Thank God I found this. My F22 has been sitting in the driveway for months waiting for me to learn it's flight characteristics. Looks like I'll be taking her to work tomorrow.
Kind of comes with the Job. In USAF we have "Training the Trainer" programs. Required training we have to have in order to teach any procedures to personnel without the training. Basically a program that teaches how to teach. :)

I was thinking he must be pretty bright to be an engineer and a fighter pilot at the same time, then he says war is his favourite thing because he likes "to protect people from bad guys".. Incredible, and I thought by now even the most clueless person on earth would now wars are fought for economical interests, not freedom or "bad guys".. Sounds like he watches too many cartoons.. Or people are just dumber then i imagen
Wow, I think the most amazing thing in this video is that you have a literal f-22 test pilot who is also a highly decorated engineer, phd, and many other qualifications, educated at freakin MIT and Harvard, and there’s a student surfing the internet looking at yoga poses. Absolutely incredible.
You can tell he's a fighter pilot, his mind is going a hundred miles an hour all the time, he's always thinking ahead, and he knows everything about the plane he was flying,
Physics and math teacher here, really enjoyed this. He teaches very clearly and directly. I also like a conversational teaching style, was nice to pick up some good habits from him as well!
"I also like a conversational teaching style" that's because he's entertaining you and NOT TEACHING ANYTHING!!!!!!!!! God please DO NOT pick up some habits, unless you don't actually want your students to learn. What did you actually learn about the flight controls? NOTHING because he only talked at the most general, skim the surface, Sesame Street level. This is supposed to be a prestigious engineering college and he talked to them like they are babies. Now in his defense they probably do have the intellectual level of babies because the education system in the US has been continuously dumbed down for decades.
This piece is on a topic of mild interest for me. After listening for a few minutes, it became a topic of more intense interest, not because I suddenly want to qualify on any particular plane, but because it was impeccably presented and sequenced. An excellent use of an hour of my day.
Physical condition , vision , training, focus ,and knowledge ,i was told as a demo flight on a Super Etendart French Fighter jet ! And what an awesome experience of 25 minutes adrenaline ! Today after more than 45 years , I'm sure it is a pleasure from the stand point of controls, informations , automatic computer control if any pilot becomes confused or disabled , besides graphics , for me is the right side of astronauts to be ! For me flying is the reminder to how small we are , and how beautiful this planet is , I'm not taking anything for granted , went to remote places and people shows openness ,honesty and humbleness !
I just found myself spending 1 hour like if it was a 1 minute video. Astonishing lecture from a wonderful teacher who combines passion, knowledge and experience along with intelligence and pedagogy... I am sure even a 10 years old kid will clearly understand and enjoy this wonderful lecture
I wanted to be there asking questions, i know its not to everyone's interest, but engineering wise, the f22 is a pinnacle, and the students didnt participate or "lean forward" at the luck they had that day, such a talented man, that could explain every nook and cranny about that engineering megalodon
@zakslt Pedagogy... I wanted to thank you for introducing me to a new set of words. BUT... Being overly pedantic, the grammatical use of the word is incorrect, as his passion, knowledge, intelligence, and experience summarize his merit and approach to pedagogy. Also, adding an adjective, like personable, ahead of pedagogy, would validate your use of it. I should actually say 'should validate' because I'm not 100% on that. Great word! Thanks again!
@@joaorodrigues-dy9rm I don't think they "didn't ask any questions". Pretty well just got to see the lecture part, and the later QnA part was cut out from the video. There's no way on earth I can believe that a brain as curious as a person getting admitted to MIT, which can fill up with a plethora of complex questions, which we normal-beings can't even begin to comprehend, on seeing the simplest of daily-life happenings, did not get any questions after attending a lecture on such a technical topic.
This guy is so smart and likeable it seems as if he spent a couple thousand years in a groundhog day learning all this stuff perfecting his craft. What a great lecture.
@@foobarmaximus3506 many who comment negatively, do so because they themselves do not understand what actual intelligence is. They themselves believe they are smart, not realizing that "the entire picture" is beyond what they see (because they lack the intellect to process information beyond their brains limits). They believe they see the "bigger picture" (have all the information), and therefore will formulate an opinion based on what they think they know (which generally isn't much)...but they don't know that. By definition, they are ignorant, and because they are intellectually in ept, they don't even realize that they are making a subjective comment, ignorantly believing it's factual. Their ignorance is painful and embarrassing. They are clueless that smart people laugh at them (assuming they even waste any thought on the dumb comment/s).
Randy is the ultimate professor, he brings his experience and technical knowledge to the classroom in such a way as to make all of us wish we were pilots.
What technical knowledge did he bring? He's so bad that he completely screws up how the ailerons work @19:47, and when the teacher asks him what the rotational speed is at take off @35:25 he only talks about linear speed! THIS IS A JOKE THAT ALL OF YOU THINK THIS IS WHAT DEFINES A GREAT TEACHER
@@christopherjoseph651 by "What would be a typical rotation speed?", he means the speed at which you input pitch commands to the aircraft to "rotate", as in pitch upwards and take off.
Fast is great. I love the "but we'll get back to that later" with no plan of getting back to it method he uses. After about 2 more sentences both he and I have both forgotten what we're supposed to get back to later. 😂
I wish I were 25 and had someone like you visiting my classroom. I'm 55 and a computer flight sim fan since 1982 even before it was released on Microsoft. I just love anything that flies and find your enthusiastic lecture simply rejuvenating. Thanks.
Very articulate and everything is in his mind ready to express. No notes, no teleprompter, all from experience and knowledge. I love the humble yet genius way Laz gave this lecture. I am inspired and can only imagine how well received by the students!
@@wakonalds3469 Yeah. Luckily I'm from the panhandle lol. Not too bad. And then finished up my enlistment at Sherman Field. Blue Angel practices from the control tower were sweet though.
@@watchandjewelryloft4713 I’m AT3 now. It wasn’t too long ago when I went through NAS. Yeah seeing the Angels practice each day really made chow more enjoyable. They’d always fly 10-12.
No idea why I am watching this but damn, he makes this subject so interesting and easy to understand even for someone like me who has no clue about planes.
Mr. Gordon is phenomenal! After a few seconds I saw the one hour+ length, after 7 minutes I was bound to his lips. One of the best things he said: "I'm 100% zero different from anybody in this room" (he doesn't put himself above of his audience). Great course, I wish I could be there.
That's really cool. To be a test pilot on a high-end fighter you have to have the intelligence for aerospace engineering, plus the coordination for stick+rudder skills (and piano!), plus the emotional fortitude to handle life-or-death situations in real time. Really anybody with even one of the 3 is blessed. Then there are a few (very few) people like this...
That's actually a tradition in the Air Force to party and set a wicked piano on fire, while one of them plays "Great Balls of Fire" till he can. At the end they collect money to get a new scraped piano for the next party.
My fist degree is mechanical engineer, then later in life I achieved my degree in computer engineering. Watching this gives me the urge to hit the campus again. The bod is a little creaky but the mind is still hungry. The wonderous creativity of the human mind never cease to amaze and inspire. Excellent lecture!
Role model? Iwas also thinking he must be pretty bright to be an engineer and a fighter pilot at the same time, then he said war is his favourite thing because he likes "to protect people from bad guys"..

Good comment man. Don't pay attention to the negativity; some people only see things through a political lens. GI's coming back from Vietnam got spat on at the airport and called baby killers. Go figure.
@@Defender78 Indeed. He's a brainy machine, no doubt. This is really what "smart" looks like. Not all smart people speak this well, but he is an omnipath. Pretty rare, actually.
This dude gave us 15 "last pieces that he will give us" and I was listening to every single word. NOTHING makes me wanna join the air force and die to a parachute training dummy more than this lecture. Thanks Laz
"Why do I have a random ass lecture on F-22 fighter jet controls?" -1 hour, 6 minutes later "Why don't I have more good lectures like this recommended to me?"
Both my father and I were in commercial aviation, both of us flying and servicing helicopters, from the late 60's to early 80's, and yes, they can be a handful to fly, the margin for error compared to a fixed wing is extreme, it takes a completely different skill set to operate a rotary wing effectively ... The rest of this lecture I found very interesting, the pilot giving it, animated and interactive, loved his style of lecturing. I am sure those attending this understood just how experienced and skilled "Laz" is as a pilot and instructor... Thank you !
Hello! I am an F-15A thru E model crew chief here(USAF for 21+ years, now retired). I really enjoyed this type of instruction, it very accurately reflects what the military used to do for instruction and training. Not so sure they are still on that same path anymore or not judging from the outside now. I was also at Edwards for a few years and learned a TON about the F-22 even though it wasn't my airframe(there in the mid 90's), and a lot about the F-23. Every one of the civilians I spoke with while there said the F-23 was slated to win because it flat out was a better maneuvering aircraft, it just didn't have the range of the F-22. So the F-22 won by range criteria mainly. Now, what I find interesting is how they(the USAF and US military in general) have since picked back up the F-23 and started examining it for the next generation of fighter....Really looking forward to the advances that is keeping America dominating in the battle space above the ground and beyond.
That's simply not true, the F-23 DID HAVE THE RANGE. In fact it met or exceeded all the requirement set forth by the design cryteria. That's coming from all the Flight test pilots, including one who flew both the F-22 and F-23, Northrop and Lockheed test pilot Paul Metz, who said "the F-23 was a clear winner,It lost because of Politics, in that the government felt that Lockheed had more experience in this design support because of its experience with F-117. The F-23 was better." I tend to believe those who actually flew it. And That's just Fact.
Honestly, he's a typical test pilot in terms of disposition. In a conference room full of engineers, everyone goes silent when the test pilot speaks. He doesn't have to shout. The engineers know whose ass is in that cockpit.
professors dont make people smarter. you fail to understand what intelligence is or means. ironically, one would have to be of your proposed "smarter" lot to realise that in the first place, guess you have a long way to go as well (based on your own retarded logic)
These type of guys are so far and few in between. My entire High School career there was only one professor that had a great personality and could keep me interested on the entire course subject even with subject matter I could care less about. In college I only had two professors with great personality. One was the Sci-Fi nerd who would put joke answers on multiple question tests that none of the class caught except me. Doctor Who references Star Trek references and made up science. Like listing types of crystals one of them being dilithium. Really give it up to teachers though it's more of a sacrifice than a career. They should be respected more and paid more for it
Yet students would still chat of Facebook. The thing is, not everyone is interested in aviation, especially military aviation. Like some people just really dont find it even remotely interesting or important. Sure we can say "b-but, its like the pinacle of our "moving" technology" (except maybe space flight, but that is SO different), but what does that really mean? What is the cold hard value of this principle. Its nothing. Noone cares. You can know flight physics and technology forward and back, have thousands of hours on a simulator... and still be a "loser" in the eyes of society, unless you make it all into a careeer or business... :(
The question why wings are on the top of "cessna-type" planes was left kind of unanswered so I will try to do it here briefly. When you design "normal" plane, you want to make it stable, meaning: without any input or with a little "wrong" input from pilot it should just flight straight instead of just bank on one side and lose all the lift. The easiest way to do this is to put sum of lift forces from both wings above the center of of gravity, so you make plane being "pulled up" by wings (in contradiction of wings "pushing up" the plane in which scenario your center of gravity can slide to the side if its not directly above the lift force). There are two common ways to do it, in most airliners wings are mounted at the bottom (for many reasons) and go slightly up as you approach the tip of the wing, so if you are flying straight, forces from your wing are pointed a bit towards each other (thus, generating a bit drag, as a tradeoff for stability), when you bank left, your left wing will have force from your left wing pointing more upward and your right wing force will be pointing more to the left (so less upward) and create feedback loop which will level your plane back to going horizontally. Now, if you put your wings on the top of the plane you don't need them pointing upwards because you already have your lift force above the center of gravity. In fighters which are fly-by-wire, you don't care about stability, computer will correct all input mistakes made by pilot and other factors, thus, trading off stability for less drag and more maneuverability seems like a good idea. Disclaimer: I'm not aviation expert, so this might contain some inaccuracies or even be wrong, I just don't know why visibility was main reason pointed out in the lecture for wing placement and aerodynamics and plane stability was somehow dismissed. I think this video explains it better than me: th-cam.com/video/ODP9efQBddA/w-d-xo.html
Then on large aircraft with very heavy engines and long wings, like the B-52, Il-76, C-17, etc, wings are on top. The Il-76 and An-225 actually have a hump in the fuselage where the wings attach. Curving the wingtips up would be difficult with the giant engines hanging from them, and the engines would strike the ground if the wings were low. Or they'd need a very tall landing gear, which is not a good thing on a superheavy aircraft; they actually want to have short, thick landing gears that are practically on the side of the plane instead of the bottom).
@@RsRj-qd2cg You don't need wings curved up in An-225 because of the effect I've described above. In fact, wings in An-225 are pointed a bit down to reduce pendulum effect because it was to hard too maneuver (yes, you can overdo with stability too). Engine weight is not a factor here. Plane needs to maintain its shape regardless of where engines are placed, for B-52 and other heavy-lifting army machines it is good to have engines at the top to reduce problems when using dusty runways. There are many factors here, but weight of engines is not one of them. If you are afraid of engines hitting the ground you can always place them on the top of wings, the downside is that whenever you increase the thrust your nose will go down a bit (but this is the case for topwing planes as well).
@@proosee anhedral high wing aircraft also have stability due to pressure forces. The low side wing has much higher presser at the wing root causing a restoring moment. High side wing the opposite. The high side wing is flatter to the flow and would generate more lift causing negative feedback. Low side wing less lift. They are still stable in this configuration since the forces balance out. (otherwise we wouldn't fly planes like that) You're right that there is such a thing as too much stability. If a plane was too stable, you couldn't fly it. It would only fly itself!
@@cluerip I think this is just a different perspective on the same phenomena, but I really appreciate your comment, never thought about it that way, seems like deeper analysis. What about F-22? I once heard it is on the edge of being unstable, so without fly-by-wire systems human would be unable to fly it, can you confirm it or deny it?
As an aircraft maintenance engineer student, it is indeed an engineering marvel but the maintenance and logistics of f22 are a huge nightmare for us considering the parts they uses are way more complex and different from conventional/4th gen aircrafts
@@yuigahama3189 sometimes i forget these arent like your average corolla, and that keeping all the parts and supply chains organized must be hella difficult considering the low production volume When you say the F-22 is more complex than 4th gen aircraft, what parts are more complex? I was under the impression that F-22s are aerodynamically similar to other airfarmes, and that its only the electronics and stuff that are wildly different. Im just in highschool so idk much abt this stuff
@@tommy.vercetti2003 Nah not really. Usually with cars, you have a large volume of production. You can make a shit ton of factories and pump out all the parts you need easily enough. Aircraft need a large database to track every single part installed or uninstalled, and a full history of every single aircraft that part was used in before. They also have sensors and whatnot operating on the aircraft in real time, to basically mesage back to Lockheed Martin, to tell them how many more units must be produced in the near future. F-22's are especially difficult, beacuse they probably dont use the same database that every other commercial airliner uses. Im also guessing that because of the low production and compartmentalization of information, its probably painfull to manage that aircraft.
As someone who’s passion is aviation this was such a neat presentation to watch. As an A&P Mechanic I got a good chuckle watching a room full of aeronautic engineers incorrectly state the positions the ailerons are in when a Cessna is banking to the right.
I stopped the video and ran to my flight simulator to check. He probably just got confused when he turned the airplane around to match the audience's perspective.
Brilliant mechanical minds think alike... As a a10 flight control maintained manual reversion is real reverse flight control surface movement explained. Its the control surface taps that fly backwards...
Man i remember watching this video at like 250K views and thinking holy shit, its perfect. The kind of video that could make a non aviation enthusiast fall in love with this plane. The eloquence intermingled with a certain playful curiosity but also encased in military poise, combined with the instructors depth of knowledge well beyond the boundaries of the actual aircraft, make this an absolute gem.
Reminds me of engineering in college when I thought a final project/presentation on propulsion and wing lift would be EASY. I teach engineering now and came across this lecture for some inspiration. So glad I did.
The cool thing was a few years back at the Cleveland Air Show, they finally had the full F-22 demo, and he was doing Cobras and controlled flat spins and it was very, very cool, but then it finishes up and flies off. Then I look back, and there’s the Goodyear Blimp, and it’s getting closer and closer, and then it floats gracefully over show center (and it is HUGE), does a 360 degree pirouette, takes a bow, and floats away. It was such a neat contrast to the F-22.
Great presentation, I don't fly planes, I am a grandmother who has 3 grandchildren who will see this and know how far they can go. I watched it 2 times.
This ladies and gentlemen is how you teach something to someone, who has an interest in it but no prior experience. The biggest problem right now is education is how to keep your students engaged in what the instructor is talking about. This man has mastered that issue., and it shows in his presentation
But didn't actually teach anything. So you keep your students entertained and they learn ABSOLUTELY NOTHING! The biggest problem is that students don't want to learn anything, they want the degree so they can make the money but they don't give a fuck about the actual subject
A good teacher is not one who impresses his audience but one who inspires them through his passion. This guy is passionate about his stuff, you can tell he is good at it.
Col Gordon is a great person and an excellent leader had the honor of working for him out at Edwards AFB at the F-22 compound while him being the squadron commander. Hope he gets his stars soon. Love the fact that the Raptor model has an ED (Edwards AFB) tail flash.
Was about to sleep when I saw this on my recommendation. Started to watch the first 5 min and ended up watching the full lecture for the guy's enthusiasm. You guys at MIT are really lucky to have Lecturers and professors like this.
The USAF has people called "patches"--men and women who graduated the USAF Weapons School and wear a special black and gray patch--and I know a few of them. They comprise the short list of the smartest people I've ever met . . . and that Test Pilot patch is a whole other league.
And the one's I worked with at NASA were the top .001 percent of those. Yeah. Work daily with astronauts, then get back to me. Air Force. LOL Shit, USN aviators are better than anything the USAF ever let in a cockpit.
Watched this thing fly in Pensacola FL. I've never seen a jet that can flip around, cobra, and do stall maneuvers the way it does. It's unbelievable how it moves! Was in complete awe of the performance. It felt like I was watching the laws of physics being broken left and right. An absolutely amazing and beautiful aircraft.
I agree with you 👍🏽 F22 it's a Incredibly amazing plane .. But I found some plane Which literally broke the rules of physics and would make you like 😯 How the hell is that possible 😂 The name of the plane is Sukhoi 35 I think .. But the Raptor remains dominant in the sky
3:31 AM here and I'm enjoying every bit of the video - such a awesome piece of machinery, more amazing teacher. Wish I could be there on MIT to learn and experience that
Why is he such an amazing teacher, what did you actually learn, ABSOLUTELY NOTHING. He didn't go into any details on even one topic. He's so bad that he completely screws up how the ailerons work @19:47, and when the teacher asks him what the rotational speed is at take off @35:25 he only talks about linear speed! THIS IS A JOKE THAT ALL OF YOU THINK THIS IS WHAT DEFINES A GREAT TEACHER
Lecture this informative from an experienced lecturer/pilot, I would definitely pay the tuition first hand. It's a blessing TH-cam shares this content.
I notice that this is only the *Declassified* stuff, classified stuff might include the: anti gravity generator, and cloaking settings and emp beam emitter manual
Who searches for this stuff? Not me. For the first time I got a recommendation that I actually loved. Truly a fascinating experience. What scares me? Well let’s just say I recently saw Boston dynamics robots dancing. Now I’m envisioning the Strauss waltz with a couple of F 22s in the sky… 🤣
Richard Baxton piloted his Recon Rover into a fungal vortex and held off FOUR waves of mind worms, saving an entire colony.

The real story would just hurt sales, and dampen the spirits of our customers„ "Mythology for Profit" Morgan Stellartots Keynote Speech
This is so amazing. I turned 35 today and was about 9 years old, when I played F-22 Lightning. 26 years later somebody on the internet explains me all the things I wondered (well, not all of course) about this plane.
it's really interesting to see the corollaries of handling, stability, control between the f-22 and that of a racecar. both boiled down to a rigid body - with 6 degrees of freedom controlled by a combination of forces and moments.
Indeed, aerodynamics and weight are two of the most important elements of aircrafts and motorsports, especially the more complex ones like, Formula 1 and WEC.
19:49 They mix up left and right. If you do a right turn, the right aileron goes up and the left one goes down. The left wing produces more lift as the right wing and as a result, the plane banks to the right.
I just had to come down to the comment section to see if some one else caught that.. I was like nah that can't be right, but then again it's a bunch of MIT students that have flight experience AND its a test pilot giving the lecture
I love how he makes everything so understandable! That's because he ONLY TALKED ABOUT THE MOST SIMPLISTIC things. If someone didn't understand this they are so dumb they may as well be dead. I really hope you didn't come away from this thinking you learned something about the flight controls because you didn't. A great teacher makes things that are complicated easy to understand, NOT someone who makes the most simplistic thing easy to understand. Teachers that only teach the most simplistic things are HORRIBLE teachers because they don't actually teach anything
Not sure if someone pointed this out in the comments, at 19:55, aileron on left wing should be deflected down and aileron in right wing should be deflected up. Down deflection increases camber of wing thus produces more lift on the left wing.
Excellent presentation, this makes up for the physics professor I had that told us all that we had to come up to his level and will fail anyone who doesn't. This guy is a true performer in every way...kudos !!!!!
43:25 "I could put my kid in a F-22 he could turn the stick all day at any speed and nothing bad would happen to the airplane" I wonder what would happen to his kid though :D Jokes aside, such a fantastic way of lecturing. To be able to explain such partially abstract and complex things in a way that even someone like me without any or close to no prior knowledge about flying can understand what he means is fascinating.
You realize this is akin to the tech going into self driving cars. (Though self driving car tech is actually more complex due to the image processing software…it’s super complicated stuff to do virtually real-time). They could easily make this plane into a remotely operated drone nowadays. No risk to a soldier, and cheaper.
This was an incredible privilege to watch. So much fascinating and interesting details about what its like to fly this plane and what makes it work. I was actually surprised that he was willing to reveal so much of the performance characteristics. Regardless thank you!
You'd be surprised what is considered unclassified info. A lot of things are modular to the point where only the most specific part of data is classified and all else is unclassified.
The moving of the aircraft control surfaces are seen in the demo's of the F22. The Cg and Cl position in slower flight is that gives the headaches to be duplicate from the others
Very informative, I learned some things about flight controls and I was involved with the manufacture and quality management of the flight controls of vertically every aircraft in the US inventory. In 1974 at 17 yrs of age, I was employed at a company that manufactured the pitch and roll control & allerion rudder interconnect for the F-15 Eagle. We also did the controls for the SR-71 Blackbird, the Space Shuttle, Lavi jet fighter for the Israelis, The Saab JAS 39 Gripen for Sweden, The AIDC F-CK-1 Ching-Kuo, commonly known as the Indigenous Defense Fighter for Taiwan. We also manufactured flight controls for Boeing, Airbus, Bombardier and others. Toward the end of my employment, we were working on the JSF, Y-22, F-22, V-22 and other aircraft controls. My employment in this field had me traveling, working and living in other countries around the world and it was very satisfying to say the least.
@@Shaker626 you make a great point! Let me explain a little: when I graduated from high school, I started at this company as a machine operator, over the years I advanced thru something they called “a bidding system” we were growing fast and there were a lot of job openings to bid on, so I took advantage of this system. Eventually I advanced into a engineering position even though I didn’t have an engineering degree, because I showed that I could learn to do the job over time. I admit that I was very fortunate and in the right place at the right time and it was great! You’re right that today this kind of thing doesn’t happen anymore and I think that’s sad.
I could take 1000 hours class from this professor on any topic, he's just great at everything he does, the tone, the speed of delivery, the knowledgeability of the topic, his interactions with learners, encouraging questions by rating them great questions, not shying away from any topic and in the same time staying within the boundaries of confidentiality. he could teach how to fly a plane in a nursery school.
HIGHLY interesting! I was an RAF aircraft engineer then later a pilot. I was a 'flight test observer' on helos. Basically after a complete tear down and overhaul I would go up with the unit test pilot as one of the lfiying engineers. If there was a fault we would land in a convenient field I would hop out and make adjustments then back up! The pilot would sometimes hand me the aircraft if he felt a vibration etc and sak me 'how does this feel to you'? we were also taught to fly. This is very like my 'theory of flight' section of my training! SUPERB!
I've never seen anyone who could so clearly communicate concepts with their hands. When he said wing tips or negative G his non verbal communication instantly made me understand what he meant. Really good lecture.
That was great, thank you. The people who designed and wrote the code for this aircraft must understand aerodynamics and propulsion so incredibly well to get it working like that.
These planes are 35 tons, real heavy! I thought they were lighter. I realize now how full of equipment and stuff they have to be. Other revelation for me is that bombs can be as heavy as a car, and the electronic system has to deal with recovering center of gravity by moving fuel when they are released. Amazing!
@@erazn9077 The plane itself is heavy but it isn't made with heavy metals (lead, mercury, thallium, etc.) Well, maybe the solder joints are soldered with leaded solder, but that's about it. The rest are all titanium and composites, glass, copper and aluminum wiring, and FR4 for electronics
Fell asleep watching another TH-cam video on rc airplanes (which I have an obsession with lol) and woke up to this video believe it or not gradually . Felt so natural and informative I think I will make it my new morning alarm ! Seriously though dude has an AWESOME teaching style !
Fighter pilots spend the better part of their careers teaching. He's studied, but you'd be amazed how many hours he's spent briefing, debriefing, and instructing.
19:45 I believe you had the Cessna aileron positions reversed in the right bank example. This is one of best videos! Great job and thank you very much for your service Sir!
I don't think I'll ever get to fly an airplane because I get motion sickness, but this was really engaging. Also, being able to access a free MIT course is incredible.
Funny thing: I got (and still occasionally get) motion sickness, so when I started my private pilot training, I was susceptible to nausea and frequently got sick in training flights, especially on hot days when we flew down low in the bumps, or when I went under the dreaded "hood" for instrument training. After about 30 hours of suffering through it, though, I mostly got over it. It became much easier to deal with and my inner ear wasn't as bad. I still get sick if the air is really bumpy but keeping my eyes on the horizon and knowing that I have 200 hours in the cockpit somehow made it easier to deal with. YMMV but it's a good data point at least.
It can be cured. Take very short flights and stop as soon as you feel nauseous. This builds tolerance. It can be made much much worse if you keep going until you barf. After that you tolerance goes down.
Great talk by Laz. I'm an airplane fanatic, former F-15 avionics tech, 21 year USAF retiree, and I love hearing the engineering aspects behind plane design. Having grown up watching the development of the F-22 and knowing the combat power it can project, it's an amazing system. This was super interesting and you can tell Laz loves his job which made it even better. :D Hate to say I'm jealous that his "other car is an F-22", but geez, can you imagine going to work and your office cubical pulling 9Gs? I'd love to talk shop with him! 😂
This has to be the most entertaining lecture I've ever seen. Once you start watching, you cannot stop. He make concise statements. Easy to be understood by 7 year olds.
As an F-16 Avionics Tech, I saw a Pilot giving a speech on Flight Controls and thought he would have no clue what he was talking about, but turns out he actually understands the Avionics behind it very well. Nice lecture!
@@currentcommentor8745 Most pilots have little to no idea of how the Avionics works besides the surface level interaction between the Jet and the Pilot. This pilot did his research and put extra time into understanding the System Theory behind the avionics.
@@BamaNick he's a test pilot, it's his job to understand the engineering while he's live testing it in practice. The things these guys do for a living... Literally flying straight into mountains/terrain while testing automated terrain avoidance systems. I mean, come on.
@@tomaszwota1465 I mean what you said doesn't disprove my point of most regular pilots not knowing system theory completely. But Test pilots obviously have a higher standard of knowledge than regular pilots need.
You’re probably better off going to a part 147 school and becoming an aircraft mechanic. Or an actual pilot. I’m an aircraft mechanic and i love my job.
Man this Randy guy can present! If I knew what he knew i wouldn’t be able to speak as fast and organize my time segments. Phenomenal instructor and public speaker.
Let me clarify my last comment...At around 19:47 the guy (and an audience member) says if you bank the aircraft right your right aileron is down. Wrong...it is up, the left is down. The right being up provides the drag/negative lift to drop the right wing and the left aileron being down provides the drag/positive lift to raise the left wing. And I do not have a pilots license.
@@mountainbikingwithlogan6163 no the op is correct, if you move the stick right the right aileron will come up, the same when you pull the stick back the elevator will go up, the flight surface always comes up to the direction you move the stick/yoke/rudder pedals.
@@rohansthill6224 Nope L Peddle is right! If you move the stick to the right the right aileron will go up making that wing go down. Just like when you pull the stick back the elevator goes up making the tale of the aircraft go down and the nose go up. Well At least they have done so for the 2000 hours I have logged as a pilot.
22:06 it does feel like it sure would! You can search on TH-cam an F22 pre-flight check and you see when they test the elavator the whole thing shakes, which is nuts
@@foobarmaximus3506 yeah I had a similar experience, I was taught most of my higher level math, technology and science classes by student teachers who seemingly had no teaching experience.
Fantastic Lecture and great speaker, however your correct. I only fly RC planes but part of our check is right stick right aileron. I think they captured the point that they move opposite.

Pedagogy... I wanted to thank you for introducing me to a new set of words. BUT...
Being overly pedantic, the grammatical use of the word is incorrect, as his passion, knowledge, intelligence, and experience summarize his merit and approach to pedagogy.

Hello! I am an F-15A thru E model crew chief here(USAF for 21+ years, now retired). I really enjoyed this type of instruction, it very accurately reflects what the military used to do for instruction and training. Not so sure they are still on that same path anymore or not judging from the outside now. I was also at Edwards for a few years and learned a TON about the F-22 even though it wasn't my airframe(there in the mid 90's), and a lot about the F-23. Every one of the civilians I spoke with while there said the F-23 was slated to win because it flat out was a better maneuvering aircraft, it just didn't have the range of the F-22. So the F-22 won by range criteria mainly. Now, what I find interesting is how they(the USAF and US military in general) have since picked back up the F-23 and started examining it for the next generation of fighter....Really looking forward to the advances that is keeping America dominating in the battle space above the ground and beyond.
Thank you for your service and keeping our skies safe.
That's simply not true, the F-23 DID HAVE THE RANGE. In fact it met or exceeded all the requirement set forth by the design cryteria. That's coming from all the Flight test pilots, including one who flew both the F-22 and F-23, Northrop and Lockheed test pilot Paul Metz, who said "the F-23 was a clear winner,It lost because of Politics, in that the government felt that Lockheed had more experience in this design support because of its experience with F-117. The F-23 was better." I tend to believe those who actually flew it. And That's just Fact.
i can attest to the military still teaching the same way as this lecture. The best teachers i have ever had were all Sgts, Majs, and retirees.
This guy is one of the most humble people I have ever witnessed
Honestly, he's a typical test pilot in terms of disposition. In a conference room full of engineers, everyone goes silent when the test pilot speaks. He doesn't have to shout. The engineers know whose ass is in that cockpit.

@@tunacant9106 abso fucking lutely.
These type of guys are so far and few in between.
My entire High School career there was only one professor that had a great personality and could keep me interested on the entire course subject even with subject matter I could care less about.
In college I only had two professors with great personality. One was the Sci-Fi nerd who would put joke answers on multiple question tests that none of the class caught except me. Doctor Who references Star Trek references and made up science. Like listing types of crystals one of them being dilithium.
Really give it up to teachers though it's more of a sacrifice than a career. They should be respected more and paid more for it
Yet students would still chat of Facebook. The thing is, not everyone is interested in aviation, especially military aviation. Like some people just really dont find it even remotely interesting or important. Sure we can say "b-but, its like the pinacle of our "moving" technology" (except maybe space flight, but that is SO different), but what does that really mean? What is the cold hard value of this principle. Its nothing. Noone cares. You can know flight physics and technology forward and back, have thousands of hours on a simulator... and still be a "loser" in the eyes of society, unless you make it all into a careeer or business... :(
The question why wings are on the top of "cessna-type" planes was left kind of unanswered so I will try to do it here briefly. When you design "normal" plane, you want to make it stable, meaning: without any input or with a little "wrong" input from pilot it should just flight straight instead of just bank on one side and lose all the lift. The easiest way to do this is to put sum of lift forces from both wings above the center of of gravity, so you make plane being "pulled up" by wings (in contradiction of wings "pushing up" the plane in which scenario your center of gravity can slide to the side if its not directly above the lift force). There are two common ways to do it, in most airliners wings are mounted at the bottom (for many reasons) and go slightly up as you approach the tip of the wing, so if you are flying straight, forces from your wing are pointed a bit towards each other (thus, generating a bit drag, as a tradeoff for stability), when you bank left, your left wing will have force from your left wing pointing more upward and your right wing force will be pointing more to the left (so less upward) and create feedback loop which will level your plane back to going horizontally. Now, if you put your wings on the top of the plane you don't need them pointing upwards because you already have your lift force above the center of gravity. In fighters which are fly-by-wire, you don't care about stability, computer will correct all input mistakes made by pilot and other factors, thus, trading off stability for less drag and more maneuverability seems like a good idea.
Disclaimer: I'm not aviation expert, so this might contain some inaccuracies or even be wrong, I just don't know why visibility was main reason pointed out in the lecture for wing placement and aerodynamics and plane stability was somehow dismissed.
I think this video explains it better than me: th-cam.com/video/ODP9efQBddA/w-d-xo.html
Then on large aircraft with very heavy engines and long wings, like the B-52, Il-76, C-17, etc, wings are on top. The Il-76 and An-225 actually have a hump in the fuselage where the wings attach. Curving the wingtips up would be difficult with the giant engines hanging from them, and the engines would strike the ground if the wings were low. Or they'd need a very tall landing gear, which is not a good thing on a superheavy aircraft; they actually want to have short, thick landing gears that are practically on the side of the plane instead of the bottom).
@@RsRj-qd2cg You don't need wings curved up in An-225 because of the effect I've described above. In fact, wings in An-225 are pointed a bit down to reduce pendulum effect because it was to hard too maneuver (yes, you can overdo with stability too). Engine weight is not a factor here. Plane needs to maintain its shape regardless of where engines are placed, for B-52 and other heavy-lifting army machines it is good to have engines at the top to reduce problems when using dusty runways. There are many factors here, but weight of engines is not one of them. If you are afraid of engines hitting the ground you can always place them on the top of wings, the downside is that whenever you increase the thrust your nose will go down a bit (but this is the case for topwing planes as well).
Yes
@@proosee anhedral high wing aircraft also have stability due to pressure forces. The low side wing has much higher presser at the wing root causing a restoring moment. High side wing the opposite. The high side wing is flatter to the flow and would generate more lift causing negative feedback. Low side wing less lift.
They are still stable in this configuration since the forces balance out. (otherwise we wouldn't fly planes like that)
You're right that there is such a thing as too much stability. If a plane was too stable, you couldn't fly it. It would only fly itself!
@@cluerip I think this is just a different perspective on the same phenomena, but I really appreciate your comment, never thought about it that way, seems like deeper analysis.
What about F-22? I once heard it is on the edge of being unstable, so without fly-by-wire systems human would be unable to fly it, can you confirm it or deny it?
Wow, the f22 sounds like an engineering marvel, even though the design is more than 20 years old now. I was reading its first flight, was in 1997.
As an aircraft maintenance engineer student, it is indeed an engineering marvel but the maintenance and logistics of f22 are a huge nightmare for us considering the parts they uses are way more complex and different from conventional/4th gen aircrafts
@@yuigahama3189 sometimes i forget these arent like your average corolla, and that keeping all the parts and supply chains organized must be hella difficult considering the low production volume
When you say the F-22 is more complex than 4th gen aircraft, what parts are more complex? I was under the impression that F-22s are aerodynamically similar to other airfarmes, and that its only the electronics and stuff that are wildly different.

@@honkhonk8009 Im in high school too and don’t know much but i assume its the engines and hydraulics

@@tommy.vercetti2003 Nah not really.
Usually with cars, you have a large volume of production. You can make a shit ton of factories and pump out all the parts you need easily enough.
Aircraft need a large database to track every single part installed or uninstalled, and a full history of every single aircraft that part was used in before.
They also have sensors and whatnot operating on the aircraft in real time, to basically mesage back to Lockheed Martin, to tell them how many more units must be produced in the near future.
F-22's are especially difficult, beacuse they probably dont use the same database that every other commercial airliner uses.
Im also guessing that because of the low production and compartmentalization of information, its probably painfull to manage that aircraft.
As someone who’s passion is aviation this was such a neat presentation to watch. As an A&P Mechanic I got a good chuckle watching a room full of aeronautic engineers incorrectly state the positions the ailerons are in when a Cessna is banking to the right.
Hey man I'm an AME from Canada and also played it back like 12 times lmaoo
As an A&P mechanic, you know less than nothing about this class and the people in it. A&P mechanics ... oh never mind. You wouldn't understand anyway.
They made question my knowledge about ailerons
I stopped the video and ran to my flight simulator to check. He probably just got confused when he turned the airplane around to match the audience's perspective.

Great presentation, I don't fly planes, I am a grandmother who has 3 grandchildren who will see this and know how far they can go. I watched it 2 times.
Apart from I've got 2 children and no grandkids, I'm 100% onboard with your statement. This is an awesome presentation!
This ladies and gentlemen is how you teach something to someone, who has an interest in it but no prior experience. The biggest problem right now is education is how to keep your students engaged in what the instructor is talking about. This man has mastered that issue., and it shows in his presentation
But didn't actually teach anything. So you keep your students entertained and they learn ABSOLUTELY NOTHING! The biggest problem is that students don't want to learn anything, they want the degree so they can make the money but they don't give a fuck about the actual subject
A good teacher is not one who impresses his audience but one who inspires them through his passion. This guy is passionate about his stuff, you can tell he is good at it.
Its fascinating to know that he probably has knowledge of the 6th gen fighters and might have even flown prototypes of it. What an awesome lecture
He is a man with a confidence, great knowledge and real life experience, it's such a great lecture
Col Gordon is a great person and an excellent leader had the honor of working for him out at Edwards AFB at the F-22 compound while him being the squadron commander. Hope he gets his stars soon. Love the fact that the Raptor model has an ED (Edwards AFB) tail flash.
@@foobarmaximus3506 Your comments detract more from you than from the target of your unfounded insults.
This officers lecturing skills are far superior than his even being a fighter pilot. Very special human being. Fantastic
Was about to sleep when I saw this on my recommendation. Started to watch the first 5 min and ended up watching the full lecture for the guy's enthusiasm. You guys at MIT are really lucky to have Lecturers and professors like this.
The USAF has people called "patches"--men and women who graduated the USAF Weapons School and wear a special black and gray patch--and I know a few of them. They comprise the short list of the smartest people I've ever met . . . and that Test Pilot patch is a whole other league.

Watched this thing fly in Pensacola FL. I've never seen a jet that can flip around, cobra, and do stall maneuvers the way it does. It's unbelievable how it moves! Was in complete awe of the performance. It felt like I was watching the laws of physics being broken left and right. An absolutely amazing and beautiful aircraft.
I agree with you 👍🏽 F22 it's a Incredibly amazing plane .. But I found some plane Which literally broke the rules of physics and would make you like 😯 How the hell is that possible 😂 The name of the plane is Sukhoi 35 I think .. But the Raptor remains dominant in the sky
3:31 AM here and I'm enjoying every bit of the video - such a awesome piece of machinery, more amazing teacher.
Wish I could be there on MIT to learn and experience that
Why is he such an amazing teacher, what did you actually learn, ABSOLUTELY NOTHING. He didn't go into any details on even one topic. He's so bad that he completely screws up how the ailerons work @19:47, and when the teacher asks him what the rotational speed is at take off @35:25 he only talks about linear speed! THIS IS A JOKE THAT ALL OF YOU THINK THIS IS WHAT DEFINES A GREAT TEACHER

That’s how you teach avionics, systems, and aerospace engineering. Round of applause everyone!
There was too much of water to give such praise.
Bravo
This is a great video of this talk there won't be a quiz!

@@foobarmaximus3506 how the fuck do you not know what thats from?
This is so amazing. I turned 35 today and was about 9 years old, when I played F-22 Lightning. 26 years later somebody on the internet explains me all the things I wondered (well, not all of course) about this plane.
Educational, entertaining and, above all, easy to understand for me, who's not yet old enough to understand most flight science
it's really interesting to see the corollaries of handling, stability, control between the f-22 and that of a racecar. both boiled down to a rigid body - with 6 degrees of freedom controlled by a combination of forces and moments.
Indeed, aerodynamics and weight are two of the most important elements of aircrafts and motorsports, especially the more complex ones like, Formula 1 and WEC.

19:49 They mix up left and right. If you do a right turn, the right aileron goes up and the left one goes down. The left wing produces more lift as the right wing and as a result, the plane banks to the right.
Right u are:-)
I just had to come down to the comment section to see if some one else caught that.. I was like nah that can't be right, but then again it's a bunch of MIT students that have flight experience AND its a test pilot giving the lecture
Thanks for confirming. This made me unsure of the whole lecture. Very unfortunate.
I could watch content like this all day. I love how he makes everything so understandable!
I love how he makes everything so understandable! That's because he ONLY TALKED ABOUT THE MOST SIMPLISTIC things. If someone didn't understand this they are so dumb they may as well be dead. I really hope you didn't come away from this thinking you learned something about the flight controls because you didn't. A great teacher makes things that are complicated easy to understand, NOT someone who makes the most simplistic thing easy to understand. Teachers that only teach the most simplistic things are HORRIBLE teachers because they don't actually teach anything
Yeah that's why aerodynamics engineers are hired by hedge funds and high frequency traders because the math can fry your brains
Not sure if someone pointed this out in the comments, at 19:55, aileron on left wing should be deflected down and aileron in right wing should be deflected up. Down deflection increases camber of wing thus produces more lift on the left wing.
I was going to point the same mistake out
@@ragingraven6738 likewise.
how could he not notice that. i guess standing in front of so many people can play tricks on your mind lol
@@LyroLife Ya happened to me before, thought I said one thing but something else came out :D
I let it go since he was on the other "side" of the wing and otherwise seemed so stinking knowledgeable. Still caught my attention.
I don't even own an F-22 and I still watched till the end, that's how good the lecture is.
Excellent presentation, this makes up for the physics professor I had that told us all that we had to come up to his level and will fail anyone who doesn't. This guy is a true performer in every way...kudos !!!!!
Most college instructors and professors are very very weak in the real world.
What an amazing lecture. Not only is he a god-level pilot but also an amazing teacher! The way he engages the students is amazing.
43:25 "I could put my kid in a F-22 he could turn the stick all day at any speed and nothing bad would happen to the airplane" I wonder what would happen to his kid though :D
Jokes aside, such a fantastic way of lecturing. To be able to explain such partially abstract and complex things in a way that even someone like me without any or close to no prior knowledge about flying can understand what he means is fascinating.
"Over G, Over G, Over G" Over G's create a lot of inspections maintenance has to do
They say if you can't explain it to a six year old kid then you don't know it it doesn't the field if you know it you know it
@@mosesgikeri6750 six year old are quite dumb though, as is the saying.
You realize this is akin to the tech going into self driving cars. (Though self driving car tech is actually more complex due to the image processing software…it’s super complicated stuff to do virtually real-time).
They could easily make this plane into a remotely operated drone nowadays. No risk to a soldier, and cheaper.
He's talking to young people working on a private pilot's license. LOL Yeah. It's pretty simplified.
This was an incredible privilege to watch. So much fascinating and interesting details about what its like to fly this plane and what makes it work. I was actually surprised that he was willing to reveal so much of the performance characteristics. Regardless thank you!
Yes, I was thinking the Chinese were sitting there taking notes like crazy!
Those aren’t real numbers, it can do much more
You'd be surprised what is considered unclassified info. A lot of things are modular to the point where only the most specific part of data is classified and all else is unclassified.
The moving of the aircraft control surfaces are seen in the demo's of the F22. The Cg and Cl position in slower flight is that gives the headaches to be duplicate from the others
@@MelbaOzzie plot twist: that's just the tip of F-22's powah
Very informative, I learned some things about flight controls and I was involved with the manufacture and quality management of the flight controls of vertically every aircraft in the US inventory. In 1974 at 17 yrs of age, I was employed at a company that manufactured the pitch and roll control & allerion rudder interconnect for the F-15 Eagle. We also did the controls for the SR-71 Blackbird, the Space Shuttle, Lavi jet fighter for the Israelis, The Saab JAS 39 Gripen for Sweden, The AIDC F-CK-1 Ching-Kuo, commonly known as the Indigenous Defense Fighter for Taiwan. We also manufactured flight controls for Boeing, Airbus, Bombardier and others. Toward the end of my employment, we were working on the JSF, Y-22, F-22, V-22 and other aircraft controls. My employment in this field had me traveling, working and living in other countries around the world and it was very satisfying to say the least.
Kids don't have that option anymore, too many laws and regulations now to even let a minor into such a field.
@@Shaker626 you make a great point! Let me explain a little: when I graduated from high school, I started at this company as a machine operator, over the years I advanced thru something they called “a bidding system” we were growing fast and there were a lot of job openings to bid on, so I took advantage of this system. Eventually I advanced into a engineering position even though I didn’t have an engineering degree, because I showed that I could learn to do the job over time. I admit that I was very fortunate and in the right place at the right time and it was great! You’re right that today this kind of thing doesn’t happen anymore and I think that’s sad.
I could take 1000 hours class from this professor on any topic, he's just great at everything he does, the tone, the speed of delivery, the knowledgeability of the topic, his interactions with learners, encouraging questions by rating them great questions, not shying away from any topic and in the same time staying within the boundaries of confidentiality. he could teach how to fly a plane in a nursery school.

@@chrismathewsjr Professionalism, rather. This is not the place to discuss war.
HIGHLY interesting! I was an RAF aircraft engineer then later a pilot. I was a 'flight test observer' on helos. Basically after a complete tear down and overhaul I would go up with the unit test pilot as one of the lfiying engineers. If there was a fault we would land in a convenient field I would hop out and make adjustments then back up! The pilot would sometimes hand me the aircraft if he felt a vibration etc and sak me 'how does this feel to you'? we were also taught to fly. This is very like my 'theory of flight' section of my training! SUPERB!
@The Matrix He's telling stories.
This definitely ranks in the top 3 "Most Interesting Lectures" I've ever watched. Great stuff!
Who are another two?
Yea i gotta know the other 2
What are the other two
I've never seen anyone who could so clearly communicate concepts with their hands. When he said wing tips or negative G his non verbal communication instantly made me understand what he meant. Really good lecture.
That was great, thank you. The people who designed and wrote the code for this aircraft must understand aerodynamics and propulsion so incredibly well to get it working like that.
Or at least we hope the people doing the code review do 😂😬
These planes are 35 tons, real heavy! I thought they were lighter. I realize now how full of equipment and stuff they have to be. Other revelation for me is that bombs can be as heavy as a car, and the electronic system has to deal with recovering center of gravity by moving fuel when they are released. Amazing!
They are also built with strong heavy metals that can withstand all the Gs they produce.
@@foobarmaximus3506 care to explain at all? Since you’re an expert apparently
@@erazn9077 The plane itself is heavy but it isn't made with heavy metals (lead, mercury, thallium, etc.)
Well, maybe the solder joints are soldered with leaded solder, but that's about it. The rest are all titanium and composites, glass, copper and aluminum wiring, and FR4 for electronics
We're so freaking lucky to get this quality content for free. Thank you MIT!
Fell asleep watching another TH-cam video on rc airplanes (which I have an obsession with lol) and woke up to this video believe it or not gradually .
Felt so natural and informative I think I will make it my new morning alarm !
Seriously though dude has an AWESOME teaching style !
I can't explain why i watched this. but im glad i did. Feels like time well spent.
i watched the whole thing bfore, but here i am watching the whole thing again
Engaging lectures, he has a talent for teaching.
Fighter pilots spend the better part of their careers teaching. He's studied, but you'd be amazed how many hours he's spent briefing, debriefing, and instructing.
19:45 I believe you had the Cessna aileron positions reversed in the right bank example. This is one of best videos! Great job and thank you very much for your service Sir!
I caught that too. Must've been a group brain fart.
Ow my goodness, I Was looking for this comment lol. Caught it while watching it for the 10th time :D
I thought I was the only one that caught that mistake!
I don't think I'll ever get to fly an airplane because I get motion sickness, but this was really engaging. Also, being able to access a free MIT course is incredible.
Funny thing: I got (and still occasionally get) motion sickness, so when I started my private pilot training, I was susceptible to nausea and frequently got sick in training flights, especially on hot days when we flew down low in the bumps, or when I went under the dreaded "hood" for instrument training.
After about 30 hours of suffering through it, though, I mostly got over it. It became much easier to deal with and my inner ear wasn't as bad. I still get sick if the air is really bumpy but keeping my eyes on the horizon and knowing that I have 200 hours in the cockpit somehow made it easier to deal with. YMMV but it's a good data point at least.
become a drone pilot then ;c)
It can be cured.
Take very short flights and stop as soon as you feel nauseous. This builds tolerance. It can be made much much worse if you keep going until you barf. After that you tolerance goes down.
Great talk by Laz. I'm an airplane fanatic, former F-15 avionics tech, 21 year USAF retiree, and I love hearing the engineering aspects behind plane design. Having grown up watching the development of the F-22 and knowing the combat power it can project, it's an amazing system. This was super interesting and you can tell Laz loves his job which made it even better. :D Hate to say I'm jealous that his "other car is an F-22", but geez, can you imagine going to work and your office cubical pulling 9Gs? I'd love to talk shop with him! 😂
This has to be the most entertaining lecture I've ever seen. Once you start watching, you cannot stop. He make concise statements. Easy to be understood by 7 year olds.
As an F-16 Avionics Tech, I saw a Pilot giving a speech on Flight Controls and thought he would have no clue what he was talking about, but turns out he actually understands the Avionics behind it very well. Nice lecture!
Avionics is how the pilot interacts with the plane.
@@currentcommentor8745 Most pilots have little to no idea of how the Avionics works besides the surface level interaction between the Jet and the Pilot. This pilot did his research and put extra time into understanding the System Theory behind the avionics.
@@BamaNick he's a test pilot, it's his job to understand the engineering while he's live testing it in practice.
The things these guys do for a living... Literally flying straight into mountains/terrain while testing automated terrain avoidance systems. I mean, come on.
@@tomaszwota1465 I mean what you said doesn't disprove my point of most regular pilots not knowing system theory completely. But Test pilots obviously have a higher standard of knowledge than regular pilots need.
@@BamaNick I didn't try to disprove that particular point, because why would I?
This fellow really knows the F-22 well. And can explain it to me. Amazing!
This makes me want to study aerospace engineering.
I study aerospace engineering. This is nothing like aerospace engineering. This is a class for pilots.
You’re probably better off going to a part 147 school and becoming an aircraft mechanic. Or an actual pilot. I’m an aircraft mechanic and i love my job.
@ yeah… not quite the same in structural analysis, control systems, fluids, or dynamics and vibrations…
Im an airline pilot and an artist... Thought I wanted to do aero engineering. One semester later I realized that I was wrong!
Lmao oof
Man this Randy guy can present! If I knew what he knew i wouldn’t be able to speak as fast and organize my time segments. Phenomenal instructor and public speaker.
Let me clarify my last comment...At around 19:47 the guy (and an audience member) says if you bank the aircraft right your right aileron is down. Wrong...it is up, the left is down. The right being up provides the drag/negative lift to drop the right wing and the left aileron being down provides the drag/positive lift to raise the left wing. And I do not have a pilots license.
@@mountainbikingwithlogan6163 no the op is correct, if you move the stick right the right aileron will come up, the same when you pull the stick back the elevator will go up, the flight surface always comes up to the direction you move the stick/yoke/rudder pedals.
@@rohansthill6224 Nope L Peddle is right! If you move the stick to the right the right aileron will go up making that wing go down. Just like when you pull the stick back the elevator goes up making the tale of the aircraft go down and the nose go up. Well At least they have done so for the 2000 hours I have logged as a pilot.
Oooff i was searching for this 😅
Btw you all three guys say the same...
@@x-ghost-x9532 that's exactly what I said, re-read my comment, the person I replied to has deleted their comment.
22:06 it does feel like it sure would! You can search on TH-cam an F22 pre-flight check and you see when they test the elavator the whole thing shakes, which is nuts

Or maybe more like only topics just like this.
I mean, at some point you are going to need some math and that's were the flow of easy stuff ends.

@@foobarmaximus3506 yeah I had a similar experience, I was taught most of my higher level math, technology and science classes by student teachers who seemingly had no teaching experience.
I’ve been a ppl for 25 years, Cessna, Pilatus and now cirrus. BUT I learned so much from this excellent talk. Thanks!
This was awesome even if everyone in the room is wrong about which ailerons deflect in which direction (around 19:40).
yeah seemed weird to me too
I thought it was just me. Why the instructors did not notice?
Me too. I did a school project aged 10 and made the same mistake so it really stuck out lol
Everyone knew what he meant, or I hope so.
Fantastic Lecture and great speaker, however your correct. I only fly RC planes but part of our check is right stick right aileron. I think they captured the point that they move opposite.
This is probably one of the coolest and most interesting videos I've randomly stumbled across in a long time
Honestly
19:47 I think they've meant the right aileron going up and the left one going down in order to turn right...
Yes indeed👍thought the same. And also, it won't be a turn, it will be a roll 😉
Aye, a collective brainfart, though I'm sure a couple of people were like "wait, what?" but didn't say anything because that's how people work.
@@tomaszwota1465 It might be due to peer pressure
Thank you! I was questioning my studies and preflight runups, lol
I turned back 20 seconds when he said that and had the wait what? He really said that. At first I just thought I misheard it.
