- Today I discuss the dangers of overpitching a helicopter when you are near the ground and are unprepared for it. It's very easy for a helicopter to crash if you don't follow the right procedure.
My name is Mischa Gelb and I own BC Helicopters with my wife Amy and my brother Sancho. I love taking the opportunity to bring you along to discover the life and adventures of a helicopter pilot.

The guy in the blue just had this look like "Why did I agree to go along to make a video titled Why Helicopters Crash? I hope this doesn't end up being one of those videos they recover from a crash site".
i had no idea who was flying they never said who was in control, scary
ahvlog ya. “My controls, your controls, my controls” never heard it 😐
the student most of the video
LOL
He has the face like "I don't want to end up like Kobe"
I was in aviation for 25 years and flew helicopters for 15 of those years. I flew Huey helicopters in the Army during Vietnam (1966-67) and never had enough power. Early models Bell UH-1 A/B/C and D (T53L-9 and -11 engines) would droop RPM at high altitude or during hot weather. It was not uncommon to require a running take-off on the skids to get off the ground when loaded. Many landings with a load had to be to the ground because it would not hover due to low power, especially when the OAT was near 100 degrees or more. Turbine engines will droop under the right conditions. Later when we got the UH-1H with the T53L-13 engine, power was not a problem. I flew the CH-47C during my 2nd tour in Vietnam (1968-69) and had all the power I needed.
what did they do to the huey engines replace the in line 4 cylinder with a v8 engine to improve power?
The helicopters mentioned in my comment had gas turbine engines. The size and number of turbine wheels in the engines increased power. The CH-47 helicopter had 2 engines much larger than the UH-1.
oh okay... lucky meow you lived through that era when these engines were being improved and developed!
Thank you for your service James.
what are your toys today uncle James? V 8 mustangs? or Motorcycles?
Coming in as a 30 plus year fixed wing pilot...I found this very interesting. Ground effect on a fixed wing is a different matter and can cause the aircraft to run out of runway while being airborne in forward motion below published stall speed.
I have only been in a helicopter twice but what a fantastic way to fly!!!
Rotor is the way... I have both licenses,, but I don't fly """"" BOXER ENGINES ''';;
Who’s here after the Kobe news? RIP 😢
Dimitrius Wilkins our hearts go out to his family and friends. He will be missed.
😢
Me
@@PilotYellow what would cause a helicopter to lose control like Kobe's did?
Me 💔🙁
Actually 1. "Settling with Power" is when Power Requirements exceed Power Available. 2. "Power Settling" or Vortex Ring State (VRS) is when your rotor enters into your own VRS and the more you add power or Collective, the greater you intensify the Vortex and aggravated descent (easy fix, reduce collective and pitch forward). All you need to know are those two conditions. In this example Power Requirements exceeded Power Available or "Settling with Power". I'm a 32 year Military Helo Bubba!
Very understandable explanation, Thanks! Do you still Fly Helio, just wondering.
@@lvgeorge Yes, I bum a flight every now and then with my buddies who still fly for a living. Take care😊
the quality of that video is amazing!!!
It’s the 60 FPS! Every iPhone since the iPhone 5 can shoot it. You need to set TH-cam app Settings to upload Full Quality.
Pilot Yellow, you are great guys, and thanks you for sharing your work, your art and your passion with us! Thank you Mischa.
Goran Ivanović hey thanks a lot for the support. That means a lot.
That is one extremely beautiful place you have to fly around there. Thanks for sharing the adventure!
BC for the win!
Helicopters: Making motorcycles look like a safe mode of transport everyday.
True ! I really hated flying in them!
BOTH NOT GOOD PERIOD.
Only 50-60 people are killed in helicopter crashes each year. 5,000 people die from motorcycles so you're dumb.
Flubbbs so true
I will never ride one.
i am so glad they finally showed the outside of the helicopter bc it is a great video and its set up perfectly but hard to imagine when you do not know what it looks like, weight, size, etc....great video guys!
This demo is a great example of having the vehicle being an extension of your body. Awesome flying. Happy landings.
That the go mate it soon becomes part of you .''. get that feeling
i go heli-sking every year, its interesting to get an idea of all the stuff the piolet needs to know and deal with.
expensive too.
This guy is a great instructor.
As always an outstanding video
These videos are a great tool. They helped me complete my commercial certificate.
I'm not sure what the hell you guys are talking about with the co-pilot looking scared. I see a competent and very alert co-pilot scanning the skies for other traffic and any potential hazards as well as consistently keeping an eye on his instruments.
That's how every pilot should fly.
Mike Patton, you are God. Just saying.
@@awestruckbeing5068 that was "epic" buddy.
The guy in the right seat is the handling pilot. "Co-pilot?''
Reason why he’s doing that is because he’s scared. Or camera shy
That's absolutely correct, I wonder if he's a instructor also.?
UNCLEDOUG SAYS YOU KNOW WHAT MAKES A GOOD TEACHER ? CALM SPEAKING PERSON LIKE YOU !!!! YOU SHOULD BE PROUD OF YOUR SELF !!
The Jet Ranger 206 simulator I flew never behaved poorly during the landing sims, but having flown fixed wing in real world, I always made an approach while flying forward and settling down during the last few seconds. But the throttle is governed in the 206. I never got to real world rotary wing, and now I'm grounded - medical. I enjoy your videos. Keep 'em coming.
''Gyro mate'' its fun and cheap
Guy on the left like .. bro....i thought u said u just wanted go for a quick ride....😂
Awesome recovery technique... if just happen to be landing next to a cliff...
The technique for landing in flat terrain is different. If you don't have enough power to hover, you glide forward (autorotation if needed) and make a "running landing."
Okay after watching all the helicopter crash videos and swearing I'll never enter one of these death coffins you've restored my confidence again. I plan to sight-see by way of helicopter. Thank you!
Mischa,
Your vids are great. I have 180 hours in R22s from more than a couple decades ago but opted not to continue down the path I started towards a commercial cert. You put a ton of work into these vids and your passion and expertise shows. And your playground is gorgeous. The pinnacle landings freak me out during the reconnaissance phase...they always look so tiny. I'm always relieved when you get there and the spot is large and safe.
Stay safe and best wishes.
Stefan Marraccini hey Stefan thanks for the message. Glad you are enjoying the videos. Thanks for sharing your story.
Really good. I thought about this for the recent disaster. Except i call it Panic. I wish panic would be considered more often, instead of routine excuses. Really good video.
Thank you for this and other videos, and this one is especially useful, to both a Helicopter, but also because it shows what my instructor always stressed, and that is "you flying here, but keep in your mind where you going to be in a minute or five. You always want to be ahead of yourself in planning the aircraft. You always need to have a plan for the "If's" If your landing spot isn't just right or the crosswind is more than you expected it to be, or your realizing you might have a powerplant issue, but keep in your mind about the "What If" situation. He would always say "You never take off without a plan!" cause once up in the air your ability to safely fly is a very dependent on factors sometimes not in your favor. Thank you again !
Great scenery and great video. I have to agree with the comment about removing your hand from the collective, but the pilot in the right seat had his on it, so obviously something briefed. It may be good to mention that rotor droop happens in single and twin turbine helicopters as well, even though they have a governor to adjust power to collective demands. Although most turbine engined helicopters have an timed overtorque limit to be able to fly out of this type of situation, although in most cases, forward speed is the best way to get out, and go past ETL and fly away. Keep up the good work and safe flying!
thank you sir one of my bucket list items is to learn to fly a helicopter but where I live there's not much opportunity so I learn what I can buy watching you folks and one day I'll be able to take real lessons keep safe
Always an excellent idea to practice around hard, pointy objects.
learning to fly in that terrain must make it easier anywhere else.
This is awesome stuff, again your detailed explanation along with actual demonstrations makes these superb videos.
I’m glad no one crashed a helicopter but also somewhat disappointed that no one crashed a helicopter.
This is as good an explanation of what may have happened in Calabassas as I’ve heard. Fits the data and the audio. Pilot just didn’t realize how close terrain was until too late
Simon is the gut I want to be by pilot. His eyes never stopped scanning, he has situational awareness.
Simon looked a little worried, I would too! Always great info, keep it UP!
Well done! Excellent instructional video. Makes perfect sense, you clearly understand the physics, it's shorts, sweet, and to the point. A+!
I really like those technical videos ,so informative! It starts to paint a picture great tutorial guys.
Timothy Lindsey I have to agree - these guys out together some fantastic content - keep it up!
I always wanted to know what overpiching was Thank You. You Just answer all of my Questions
While working at GE building T700's that go on the Army's Blackhawk, two pilots were touring the plant. They stopped to talk to some of us assemblers who were pulling lock wire to an assembly. They invited us to come watch them "pull pitch" as they left the plant in their Blackhawk helicopter. So at 4:00pm we went out to watch at the heliport .... and we got the best air show ever. After the flight engineer did his thing, and pilots warmed up the turbines to full power they "pulled pitch" Those two GE engines jumped that copter straight up about a 100 feet in a second... they hovered, turned toward the Saugus River and booked at full speed...just when we thought they were heading away for good....they came buzzing back at a 100 feet and headed for Boston.... an amazing display of power. That day we learned what pulling pitch was in that Blackhawk.
Great video! (Glad you did the second approach to show that committing doesn't have to be scary since you gain efficiency once you have ground effect.)
The old saying goes; "A chain is only as strong as it's weakest link." In this case the weakest link is usually the pilot.
Great job guys and very good instruction. Forget the wanna be haters and keep doing what your doing. I occassionally drop in to see the beautiful views! I fly in cow land Texas. Not much to see from our Bell 206. Fly safe brother!
Thanks for the support man. It's great to have you on the channel.
I have learned a lot from the both of you. I'm glad to know if I'm in a situation where a person needs advice, I'll sit them down and... give them your number! Thanks for the knowledge. BTW, I love how you call it being a pilot. When I call it being a Daredevil!
A few years ago I took a ride in a Bell 47 (the one from the MASH series) at Sun & Fun and while we were out tooling around I could tell we were out of power. If he just tried to sit in a hover and climb straight up, we would not gain altitude. There simply was nothing left. And the rotors began making a different noise. Full of fuel, two large adults and 100° temps all contributed. Rather than the steady chop chop chop your ears get used to, it began to beat and the vibration was much more severe. The blades were at their full pitch yet the piston engine could not keep the RPM up. I glanced over when I noticed all this and he simply muttered "...over pitched..." and had to fly forward to gain enough rotor RPM to land. Fascinating to see this first hand.
CFI Rotor here. I just taught maintain your rotor speed in the green a lot less to think about. Rolling off the power is not the same, depending on the helicopter too low of rotor speed can cause loss of tail rotor effectiveness. I teach RPM times torque equals horsepower. Keep it in the green and live.
BC is so beautiful. You sure have the best vantage point from which to see it.
Wow, exciting & well done video! I want an MD 900 NOTAR Explorer SO BAD!
Excellent video ! I like helicopters but I still think they are a madman's vehicle!
Cheers!
That's an awesome demonstration and well explained. There is a great video by Bradley Friesen actually experiencing this for real where he had to immediately dive off a cliff almost like your demonstration.
HappyCamper yes it can happen pretty quick and easy. @bradleyfriesen does a great job recovering from it.
Excellent presentation of vital flight emergency situations by these two professional aviators. Well done, guys!!!!!
The guys in the blue’s face priceless half he time
He's on the canyon drop off side and is trying to remember if he tightened the Jesus Nut.
He's doing 99% of the flying, and actually pretty busy most of the time.. N-type people put it all right out there on their facial expressions.. Notice his emphatic "no" at the end - he had been paying attention to the conversation all that time despite his high workload.
haha yeh. . . focused on Situational Awareness. . . Simon certainly shows as full-on concentrating on the machine the surroundings and the teamwork of being aware of Mischa narrating for the likes of us. . . nice team.
Haha ya he gets pretty focused when he flies.
If you ever get the chance to fly a Bell-47...do it brothers! Ive got about 40hrs in this one before they sold it. th-cam.com/video/fmt0u4LPDs8/w-d-xo.html
Thanks again for another great video
I always enjoy your enthusiasm ,knowledge ,passion
For rotary wing
Excellent! Short and concise
OUTSTANDING!!!
In 1970 in the Alaska Range I crashed (as a passenger in the front left seat) in a FH-1100. There were 5 of us aboard (including the pilot) and we were quite heavy flying in strong winds.The pilot was asked to drop me in a cirque basin, so he climbed as he angled toward a ridge line. I'm a fixed wing pilot, and I saw him trade forward speed for elevation at the same time pulling more and more torque. Right when we were just a few feet below the ridge wind buffeted us, and I noticed 106% torque when we heard a "bang" and the pilot dropped the collective ( I presume to keep/restore rotor RPM) and our skids hit the hill bending the tips up significantly. Pilot then hit the right rudder spinning us downhill where he tried to gain energy to auto-rotate, but we hit the hill 3 or 4 more times never really achieving enough energy to maintain altitude. On the last impact with the hill we came in on a steep angle striking the rotor into the ground and we slammed to a stop. The turbine had been winding down, but got ripped out of the engine mounts causing the cowling to ignite. We all piled out with the pilot cutting his right hand on broken plexiglass. We were very lucky- I recall the turbines at that time were a bit underpowered compared to todays helicopters. We were all very lucky to survive.The bending of the skids helped us from snagging the 6 to 8 ft brush we bounced through- I figured we were going to tumble into a nasty ball.
Bill Roberts wow lucky you got away with that. Using yaw control the wrong way will also eat up a bit of power too.
Drop me off there with a tent, a few buds, food and drink, and pick us up in a couple of days please... Thanks in advance. Good vid.
Case of Bud.
blankets and a tent. Keep from frostbite.
Here after Kobe also! But his Pilot was in some super fog in VFR! But looks like at 1millsec pilot seen ground try to Bank left But at 180mph +dive it too Late! And Chopper had NO ground warning proximity system!
+Lenny James I think he lost his spacial awareness and rolled the helicopter upside down and accelerated into the ground such that he thought that down was up. He was climbing up out of the fog at 5 mph forward speed and then he ended up crashing into the ground at 180 mph.
@@Islamisthecultofsin Yes sir scary ride!
@@Islamisthecultofsin No up side down roll! just downward forward pickup up speed like anything will! He crash at 1000+feet So just to fogy he didn't no that was 2,300 hill was on him! End of the Day was pilot ERR! At first airport he was holding at! He as the Pilot Need tell Kobe it unsafe right now we need sit it hold here for hour! Cause By time fire dept got up hill to the sit the Fog was about cleared up!
+Lenny James The issue I have is that the pilot knew the area. He had flown it many many times. If he gets into thick fog then you climb out of it. He was going 5 mph. It would be very unlikely that an experience pilot would dive and accelerate to 186 mph. I maintain that he was trying to climb out of the fog and ended up accelerating downward upside down which would explain the high speed at impact. Your way would basically mean that they pilot chose to dive toward the ground. If you are accelerating downward upside down you would feel like everything was normal when it wasn't.
We both agree that he should have landed and had someone take them the rest of the way by car or van.
@@Islamisthecultofsin And VFR He can not go above 500feet clouds push him in Ground! All is to it! just see this guy drop new video lets go watch see what he saying. Im not pilot just live next door to small air lot chopper in and out and stored their! for 20years bug lot guys over their for rides and teach me stuff just case if ride with some one dies flying say i can safe get us home or down!
Very interesting video, kind of proved all my intuitive thoughts about helicopter hovering, thanks for this video.
I have no training in flying
I have only been on a jet twice
But you explained it so well that in my head i can imagine what your trying to convey to the audience here.
Good job
Rip Kobe bro hope this helps ppl not end up like him and gigi no disrespect much love tho
@michael hines for real wow man good research and I think it should be a law for fog u know just for safety nice job by the way fam
Nab Rab wait till this guy finds out it already is a law...
@@timinator31 ohh fr well that interesting well when more info about the crash shows up we will see what protocol they broke
Nab Rab th-cam.com/video/cttx236mUIE/w-d-xo.html
Still a long investigation to go, but this explains a lot of speculation.
Very Nice.
Great video lesson sir. Thank you.
Ol' Terrance and Phillip are doing alright these days
4 years I am later revisiting this video as I have started training on an R22
"here we are at 15,000 feet, I'm flying in at just about 100% power, and I'm going to demonstrate for you how easy it is to crash when you overpitch the helicopter..." :)
choppers usually do not go higher than 10 000 feet. It is why emergency pick-up of climbers is not a welcomed task. They are on their own. They know the risks. Mountains are full of dead bodies. No burial needed.
@@RandySeverino And THAT was the lesson. When your copilot does something you don't like, take control, get out of danger and sort it out with speed and altitude.
Thank you, very interesting indeed. I fly fixed wing ultralights and sometimes my RC-helicopter which does not have much limitations of power. I´ve heard landing on top of a skyscraper is one the most dangerous landings for helis. Now I habe an Imagination, why .
Great video! How about doing one on how to fly in the mountains and read the winds along with how to handle turbulence? I take my check ride 12/3 and, because I watch your videos, my instructor is always impressed with my knowledge. I always credit you. Keep up the great work!
Guaranteed Home, LLC wow thanks for the support. That’s really cool to hear. Good luck on your test. That’s coming up really soon. It’s such an amazing feeling once it’s done and you are officially a pilot. I will do a video on those things for sure. I can’t promise when but I will work on it.
You can tell you’re a good pilot buddy you handle that like a good day at the office
Great video - more people need to become military helicopter pilots.
Your buddy looked like he was freaked out the entire video lol
Great presentation. Makes it easy to understand and easy to remember. 🌟
In my opinion lowering collective comes first( if height is available and then go for the turn). The turn should be a cyclic turn and not with pedals. Power pedals consume power . You are already low on it.
Great video!
Tell your brother Sancho I have cameras up to watch for him when I'm not home!
Terry W ok sounds good
Educational beast... so full of simply explained knowledge🤯
Wow these are such beautiful spots u guys work at amazing u guys so lucky NICE
Love the videos guys! Thanks for sharing!
Here after Kobe’s death .🥺🥺🙏🏿🙏🏿🙏🏿😔😔😔
qjoful Kobe? Hmm... sounds made up
Most people do not understand how difficult flying a helicopter is. It is something like juggling and walking on a high wire at the same time. The use of counter-rotating props reduces the difficulty greatly as the need for an anti-torque apparatus is virtually eliminated. As time progresses the counter-rotating prop design will take the place of helicopters using anti-torque to controls.
The scenery is just beautiful!!
that is at Mt Robson
I have a question bc i watch a TON of videos and ohmygosh your video here is SO clear and Perfect looking the quality is UNbelievable! What do you film with and what settings do you use and then what do you use for post? Seriously can you tell us bc this video is better quality then any video i have ever watched??!?!?! Great Job guys!
Autism IS I film a lot with GoPro. Anything newer than a hero 6 is pretty smooth in the helicopter. I also use a Panasonic GH5. I edit in Adobe Premiere. I shoot everything on automatic because it’s easier in the helicopter.
@@PilotYellow Thank you for the reply! I am sooo loving your channel and i just cannot get over How AMAZING Your videos all look! I now want to go back to camera filming. I have been trying to upload more and more consistently so i bought the samsung note 10+ with 512GB so i could film and edit quicker but even in 4K the quality of my videos are awful and watching your channel has motivated me to break out my camera and crash course premiere pro again (i always edited in premiere but now its been so long since i even looked at it!) Love your channel, Love your videos, and everyone has been doing it with the tech info and camera info but YOUR videos have brought in a whole new look with flying into some of the most beautiful places i have ever seen and then talking about the gopro or whatever it may be and your standing on the edge of a mountain the YOU flew too, Hell Yeah i'm gonna watch!! Thank you for doing this channel
@@PilotYellow you wouldnt happen to be going to playlist live would you? I would love to meet you if you are? I am going with my 12 year old son Joshua who are channel is mostly about (he also has his Own channel!) I will not know one person there but hoping to pick up some motivation with tons of info (and hopefully lots of fun for my son!)
Autism IS no sorry I won’t be there.
Today we're going to show you how not to crash into a mountain. Ok here's a big mountain..
..but wait, let me overload the shif out of the engine, and simulate total failure first..
good pilot and teaching skills
Happy New Year from New Zealand...awesome videos. Your confidence is frigging amazing!
This is my first video I’ve seen of your channel. I just found your channel and I’m subscribing and notifications on. Thanks for the great tips.
Excellent technique excellent photography you’re so spot on & I like the fact that you had the 2nd pilot! Why on earth would you ever fly a helicopter as large as the one that Kobe & his people were on fly without a 2nd pilot that makes no sense to me! Particularly when there are issues of weather & terrain being factors & as we all know in the aviation business spatial disorientation is especially dangerous when you get behind the power curve as multiple factors comes into play! This is just my opinion but this was an accident that could have been prevented with just a little common sense thinking before they left the ground! So barring any type of catastrophic mechanical failure which obviously could cause an aircraft to go crashing to the ground because we don’t know that at this point but if we could set that aside this appears to be pilot error! Just sayin!😱
Theodore Haskins, I absolutely agree with you! There should have been a co-pilot to help out should the first officer get into any difficulty. That - in the absence of a crippling mechanical/electrical malfunction - could have saved the helicopter and its occupants.
This guy gave me anxiety simulating the crash rolling away from the mountain
I'll leave the flying for the birds, bugs, and bats.
Dean Harrington 😂😂😂
There you go... LOL
Don't forget the elephants
small birds don’t fly
@@III333III yes they do lol
I am glad you make these vids..... I love the art of flying but I dont fly myself but I did take a 1 day course/fly an R22 and loved it... so these vids for me are the next best thing.... plus I love Canada so the scenery is jus that added icing on the cake EH!..... from down under.
moochasas thanks, I’m glad you are enjoying them. Yes Canada is an amazing place to fly. For sure.
Great video...nice lesson.. thanks
Sheldon always insists on having his spot clear ! ....... 🥰 x
Great explanations!
Gorgeous scenery, outstanding moment by moment flight description, fantastic photography, beyond impressive view from the cockpit... and one Cold Sober, Serious explanation of how to "beat the air into submission". I think I will reserve my helo flying to my dreams. I'm pretty sure I don't have the ➑➑'s for it. But at least I understand that :) Thank you for the video. Cheers!
Awesome video and Explanation! Thank You !
IGE is actually within your rotor span, not 2/3rds of your rotor span, it just may not be that noticable until 2/3rds.
Correct me if im wrong : Many say Fixed wing crashes are commonly due to pilot human error, but Rotor wing crashes are more due to faulted moving parts that go wrong in the helicopter..
i dont know what the video was about, but it was cool.
Great Video - Always very good quality and very informative
I have to agree 100% with the other comments, this would have been
first class had you done this solo, and not dragged someone in off the
street to scare the living ship out of.
Very good video! I fukken loved this information. The guy on the left was a bit too silent though.
Regarding the danger of over-pitching in helicopters:
What are the implications of electric motors for the risk of over-pitching (for both the chance of over-pitching and the ability to recover)?
My Tesla has extraordinary acceleration. This is because torque depends much less on RPM. I get instant torque without having to wait for RPM.
Would a helicopter pilot’s need to focus on torque and RPM range become less critical?
Could electric motors be a boon to helicopter safety?
Great instructional content as always guys!
Perfect example! Thx!
