Whenever I fly commercial airlines I always sit behind the wing. I love to watch the wing work. It's brilliant engineering at its best. When we hit turbulence I'm amazed on how much the wing flexes. I enjoy watching the screwjacks lower the flaps. I can't wait to watch the oncoming 2 videos. Here's a suggestion, how about doing videos on landing gear and how they work. That's more incredible engineering. Thank you.

Joe, this video is one of your absolutely most beautiful ones yet. 🤩 I'm sure many other folk will hopefully realize... while all of your videos look polished, this one is exceptionally wonderful and the work you put in and the relationships you have cultivated which have allowed you to capture this kind of footage really shine as you bring us this knowledge today.

I've gone from being terrified of flying to loving aviation because of content like this. I've even started flying in GA aircraft and hope to one day get my PPL. Thank you Joe!

Captain Joe, I am a FAA Designated Mechanic Examiner (DME) in the U.S. this was a great video on flaps and the different type and how they operate. I have the B-747 training books but real pictures are so much better than a single photograph. One subject all FAA A&P mechanics test on is flight controls and this really helps understanding for new students in aviation. Great video I have linked to your channel for students to follow along.
Wow! 34yrs as an airline pilot and I'm still amazed at the complexity and effectiveness of these systems. Wonderful explanation, systems description, graphics and live demonstration videos. Their use was thought through to the end of several possible scenarios and I'm so impressed they were designed largely in the 50's and 60's. Thanks to the brilliance of thousands in the production of these systems that our current day passengers choose to never open the window shade, complain the internet is spotty and expect a free upgrade on their next flight as a result, all while smirking through their N95 mask.
The 747-100/200 had an even more complicated leading edge flap system for reverse thrust, the 2 flaps closest to the inboard side of the engine stowed whilst the rest remained deployed, even more of a mind blower, great video for a former spanner turner 3 evolutions of 747 engineer, keep it up Joe, I miss the Queens in this age of fly by wire 👍🏻
Any chance of having a video explaining the difference between Airbus and Boeing flaps? Airbus seems to use a less complicated setup (at least in cockpit). Would be great to have insight about this.
Its just different philosophies, based on design and requirement. But tldr is boeing gives you more options (ie more flexibility), airbus gives you more simplicity (ie ease of use)

There are some decades of engineering between the 747 and a A320 or more modern aircraft. Basically Airbus has more advanced aerodynamics on the flaps therefore can use less, saving weight and maintenance whereas Boeing sticks to simpler aerodynamics and therefore less development costs on this. But Boeing catches up on newer models.
@@roichir7699 absolutely not true. In terms of advancement, they are competitive with each having selling points and trade offs. For instance the 787 replaced the concept of using bleed air from the engines to pressurize the cabin. This gives the cabin cleaner air that can be better controlled for comfort. Most would agree this an advanced technology. Airbus designed fly by wire systems that take the input from the pilots and doesn't perform the requested action if the software thinks it is unsafe. This design philosophy is divisive. Most would agree it was and is a major advancement in technology. Boeing aircraft like the 737 and 747 appear to have less technological advancements than Airbus because Airbus didn't exist when these aircraft were designed. Both aircraft manufacturers have product lines that are a result of the circumstances of the time they were made. The A340 was an incredible aircraft that entered service into a world very different than it was designed for. It no longer had a reason to exist. The 737 MAX was an incredible advancement bolted onto a Model T, but it was a result of the circumstances of the time it was made.
Great explanation on the flaps and it's operating system. The back up drives for the L/E flaps is electrical power and the T/E flaps is also electrical.
Airplanes are absolutely amazing. I found out about airplanes and their attachments when I built a model airplane 12 years ago. After building it just before flying it, I was fascinated @ the servos and how they move the wing attachments to see what makes them fly. And when I travel on an airliner, I ALWAYS get a window seat just behind the the wing so I can observe the movements of the attachments. Maaaaan..these thing are amazing!!!
Love the flexible and Krueger flaps on the leading edge of the 747-the massive triple-slotted trailing Fowler flaps are mind-blowing on the -400 and earlier versions.
Wunderbar, genau was Du schon gesagt hast! Boeing's engineering on the 747 has so much foresight and experience built into it. The 747 is, and probably always will be, my favourite commercial aircraft. Nochmals danke Dir Captain Joe für ein tolles und sehr aufmerksames Video! These nerd-bird, geek-out, videos are honestly the best!
Feeling entertained by watching the flaps changing in flight and on the runway, i always try to figure out how flaps work relative to the airflow surrounding them. Fluids are fascinating, yet so difficult to understand, except you are a physicist: We just cannot see them ... . THIS episode is the TH-cam clip of my dreams come true. Looking forward to episode 2 and 3. Thank you so much!
I used to do flight test on a B747 SP in Montreal and when we are on autopilot during cruise, I love to see the control surfaces adjust themselves to maintain KCAS and ALT. Such a beautiful sight. Beautifully done Joe!
Always love your videos. I run the fire section at my local airport and have just taken on a new trainee. Only last week was I teaching all about flaps and took him out to a preserved 747-400 which we have to point out what we had been discussing. I will show him this video to help consolidate his knowledge. Thanks very much
I always see Cargolux 747 taking off from Rio de Janeiro. Its always at night or dawn. Love the sound he makes even being in another city i can still see and hear it!
Just a correction, at about 8:50 point of the video. We are looking at the L/H body gear wheel well. The unit circled on the L/H side is a power drive unit (PDU) that operates the inboard T/E flaps. That is correct. However, the unit circled on the right is not the PDU for the outboard flaps. If I remember correctly that unit is a door operated sequence valve. The PDU for the outboard T/E flaps is located in the R/H body gear wheel well.
Commend your teaching skill...Knowing something is different, and explaining it in a simpler and understandable way is another....You are simply amazing.
Very interesting. Things we just don't ever think about or have to think about when flying. These people are so very smart in understanding how all these things need to work. Mind boggling.
The variable camber flaps work through the monkey motion of all those linkages you see at 03:42 . The linkages connect to the fiberglass panels causing them to bend as they extend or retract. Their operation is a marvel of engineering I never tire of watching.
Now I Am 56 Yrs . At Very Early Stage I Wanted To Become Pilot. But Any Way I Keep Watching Your Videos Very Explanatory Which Any Conman Man Have Curiosity Will Understand Like Me. Best Wishes & Keep It Up.
Captain Joe, thank you so so so so much for this video!!! When I took my VERY first flight back in the day, 1990 to be exact, I was a 7 year old little boy, I believe it was the 747-400(maybe) with South African Airways back in the day.

Tnx to you Captain Joe i slowly overcome the fear of flying. Whenever there is turbulence or something us going on , u just remind my self of your videos and why is that happening. So from no way i am boarding a plane after watching your videos i can proudly say that i move from 0 to 10 flights a month. Tnx captain Joe for your help
What an amazingly good video, when I was flying as a passenger and sitting by the window of the plane and looking out of the plane, the wings of the plane opened and closed, I thought about how it works, and now through this video I have found the answer.

This is the type of content your channel has been missing lately. Thanks for taking the time to film and put together all the gratuitous and salacious flap and plane video to go with your overview. Always amazed by how much the 747 changes its wing shape, and the huge angle when fully extended. Anyone know if a plane that's similar in this way? Always loved watching the wing during flight.
The midspan and outboard LEFs are called ‘Variable Camber’ because the panels actually bend to form a new leading edge ahead of the wing. This flexibility is what makes them susceptible to flutter and partly why they’re retracted during reverse thrust operations.
Captain Joe my mentor pilot. Always a pleasure and honour to learn from.Good heaven, man you are a good teacher. You always make me feel like a pilot.How I wish you were my teacher when I start flying classes.Hats off for you Sir.Good job.
@0:18 @0:38 @6:50 Anyone seen Inglorious Bastards? When he said part one of three, it reminds me, an American, of the German way of saying three vs the American way. Everytime I see a CargoLux landing in MIA, I wonder if you’re flying!Lol Keep up the awesome work Joe!!! Love your channel!
AFAIK the 747 flap arrangement is unusually complex and powerful for an airliner. In the 70s there were not nearly as much large runways, so reducing the takeoff and landing distance as much as possible was important. The 747-8 got a redesigned wing with simplified flaps because in the meantime airports have caught up to the size of modern airliners.
@@TB-um1xz Its a completely different layout, with dual element inner and single element outer flaps instead of the tripple element flaps used up to the -400.
A little story: I only learned about flaps once i accidentally press "F" in FSX, and after that i finally learned how to ACTUALLY takeoff since taking off in TNCM is always a nightmare for me :/ PS; Love the new Intro, Captain!

I like sitting over the trailing edge of the wings… I can hear the hydraulic noises of the flaps extending or retracting. My favorite flap sounds are 777 and A350-1000.
The inboard and outboard TE flap drive motors are in different wheel wells, not as shown in the video. I've never heard of a flap placard speed limit on flaps 1~20. There is no mention of it in the Boeing Maintenance Manual or in engineer training manuals. Full flap extension only increases the wing area by 21% (lift by 90%)
6:39 if the outboard flaps don't move simultaneously with the inboard flaps, this is *not* asymmetry. Left/Right Outboard positions are compared. Left/Right Inboard positions are compared. Not inboard to outboard.
Joe, what a wonderful experience you are a good pilot, and it is well deception how to use the flaps when the take-off and landing of the airline. Thank you so much for your information. 👍😊
What a great video, Joe: Interesting, informative and entertaining. I now have more knowledge about how flaps work than you could shake a stick at! Thanks, my friend.

Thank you for showing the details, I didn't expect there to be so much engineering put into these flaps.
It’s awesome that your employer is so supportive of your videos, most other aviation TH-camrs can’t even mention who their employer is
Usually thats because passenger airlines are more sensitive to PR. Hence their social media policy is much restrictive

Your videos are awesome. Nowdays whenever I am on flight, observe your points.
Another reason to love Boeing, the Queen and your channel
AFAIK the 747 flap arrangement is unusually complex and powerful for an airliner.
In the 70s there were not nearly as much large runways, so reducing the takeoff and landing distance as much as possible was important.
The 747-8 got a redesigned wing with simplified flaps because in the meantime airports have caught up to the size of modern airliners.
How did they simplified the flaps? They are the same. I will agree that the wing is more swept.
@@TB-um1xz Its a completely different layout, with dual element inner and single element outer flaps instead of the tripple element flaps used up to the -400.
A little story:
I only learned about flaps once i accidentally press "F" in FSX, and after that i finally learned how to ACTUALLY takeoff since taking off in TNCM is always a nightmare for me :/
PS; Love the new Intro, Captain!
Believe in JESUS today, confess and repent of your sins. No one goes to heaven for doing good but by believing in JESUS who died for our sins. For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.(John 3:16)🥳❤️
@@alunesh12345 what?
I like sitting over the trailing edge of the wings… I can hear the hydraulic noises of the flaps extending or retracting. My favorite flap sounds are 777 and A350-1000.
I just love the flaps on a plane it’s something about those aerodynamic fairings and those flat surfaces just attract me to sit next to the wing
thank you mr captain. Very important video for aviation students before state exam
So very clear and informative .. I learnt a lot.. Thank you so much..
The inboard and outboard TE flap drive motors are in different wheel wells, not as shown in the video.
I've never heard of a flap placard speed limit on flaps 1~20. There is no mention of it in the Boeing Maintenance Manual or in engineer training manuals.
Full flap extension only increases the wing area by 21% (lift by 90%)
6:39 if the outboard flaps don't move simultaneously with the inboard flaps, this is *not* asymmetry. Left/Right Outboard positions are compared. Left/Right Inboard positions are compared. Not inboard to outboard.
Thanks Joe for that great video with all the explanations! Won't find that very often. Can't wait for the next one!
The new skeuomorphic intro looks great!
Captain Joe To The World 🌍
Thank you for making me a pilot🙏
Very informative video Captain. Thanks for sharing.
Just a casual Great captain joe video
Joe, what a wonderful experience you are a good pilot, and it is well deception how to use the flaps when the take-off and landing of the airline.
Thank you so much for your information. 👍😊
Captain Joe Very Nice Channel and Big Information Airplane Details Very Nice Program. I Like You and Your Channel.
Thank You Captain Joe.
Mr. Joe you sounded more like mechanic than pilot with so much knowledge of the system .
I hope the average pilot know a big % of what you explained .
It's great to watch this informative video👦.
All the best captain Joe
11:04 do they extend again if in case you have to put on thrust again to performe a emergency touch and go?
I built literally thousands of those torque tubes or drive shafts that connect the gear boxes when I worked for Boeing.
What a great video, Joe: Interesting, informative and entertaining. I now have more knowledge about how flaps work than you could shake a stick at! Thanks, my friend.
I love your new intro
As an Technician (in Electrics) I like such videos so much. On my next life I will choice any technical job in aviations! 😅
Hi Joe, Great Video. Can't wait for the next two parts...
Fantastic and very informative video. Joe explains everything in details.
I love the engineering of the airplanes.
Great to have you back!
Just the usual quality and informative content. Big thumbs up!
After so long and I liked that new intro animation. I really like your videos they are amazing
Love from India
