WHY HELICOPTERS CRASH WHEN OVERPITCHED

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.

[@jamesdayton9530]

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.

[@fidelcatsro6948]

what did they do to the huey engines replace the in line 4 cylinder with a v8 engine to improve power?

[@jamesdayton9530]

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.

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!

[@Islamisthecultofsin]

+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.

[@javacup912]

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!

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!😱

[@Liger._King]

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.

[@HelicoolsHelipad]

"Over-pitching?" No, dude... it's more about causing an engine under speed which leads to main rotor droop. It's when you pull more torque than the engine can provide and the engine droops (you got that right.) The lift equation being "Lift = coefficient of lift X 1/2 air density X surface area X VELOCITY^2" ...being that velocity of the rotor system is squared, when you loose a just a little bit of rotor RPM, you loose an exponential amount of lift. This is what you should be teaching and you kinda missed the point. Performance planning is key at the planned altitude you are going for... fail to plan, plan to fail. It is more about finding and getting your target torque in early to avoid power demands that cause even slight power droops. Also, what about doing a 360 constant airspeed and bank angle to determine wind direction and speed? ...then using the terrain and updrafts to minimize power requirements. The challenge is making the landing with the absolute minimum torque applied with the minimum amount of torque fluctuations (especially positive power demands)... but then again, what do I know.

And once the blades are stopped, it's basically a rock with a tail stabilizer.

[@wtimber]

That is what I was thinking the whole time. Guess there is no stall horn on the blades

[@getsideways7257]

There's the sound of the revs going down plus the low RPM warning. But yeah, those can be heard only a bit late.

[@bensonmilam6022]

Thanks

[@fredfarkle3677]

stall horn is rotor rpm, not engine rpm. When a helicopter's blades stall, they depart the plane of rotation, and often chop off the trail and/or chop into the cockpit. Then, as you said, it's a lawn dart.

[@rizwanmahmud9353]

They said that Kobe’s helicopter was too low to begin with. Maybe it did over pitch trying to power going higher...and the pilot may have tried to correct it, but they were too low. I think maybe that could’ve happened due to not realizing how close they were to the ground. Maybe...Idk tho, because I’m not a pilot. I’m just trying to make sense of it.

[@mrjweate]

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?

[@mtatom92345]

When landing where you can go "down" and away.

[@jordanrodrigues8265]

At high altitude you want to approach a ledge like this and have an escape path. In flat terrain you often have the option of a "running landing" - landing with forward speed requires less power than hovering. It's similar to how you'd want to land a paraglider.

[@unapologetic7900]

The idiotic comments about helicopters being unsafe just because a well known celebrity was sadly killed are beyond annoying and idiotic in these comments.. news flash ignorant non pilot commenters: the NTSB has NOT ruled anything out in the Calabasas crash except the engines did not fail prior to impact with terrain. They don’t know if it’s pilot error or mechanical. Very doubtful it’s mechanical being a S-76 which has a very very clean safety record. But anything is possible at this point. So do us all a favor and stop posting moronic crap about helicopters being unsafe. They are slightly less safe than fixed wing aircraft (private) per the data.

[@carmelpule6954]

I would have thought that it is so obvious that a helicopter would crash when overpitched. Anyone who is interested in matching a propeller to an engine on a boat knows very well the result of over pitching a propeller. Reason and rational thinks tell me that if one is flying using 100% of power, he should not be there in the first place and if he is, then he better take immediate precaution to get out of that condition. If 100% of power is needed for to fly at sea level, then it is better to return the helicopter to the designer and manufacturer and tell him to install a more powerful engine.......... for the sake of safety.

This is exactly right. Ground effect breaks the vortices, preventing them from recirculating, and thus increasing the efficiency of the rotor system. Ground effect IS NOT a cushion of air.

[@stefansmuts8882]

The cushion of air is just an quick and easy way to explain it - when one instructs its hard give the full explanation every time, especially when hovering on the side of a mountain. I'm sure Pilot Yellow and his student are fully aware of the correct explanation.

You have to remember he has to balance the technical content of these videos with more informal explanations as it will be watched by a whole range of people. From those who know nothing about helicopters to a seasoned Blackhawk pilot who did a gazillion tours in combat zones, flew at 2cm over sand dunes at night with NVGs and weaved in and out through cactus plants at 160kts white hitting all the ETAs within 0.1 sec of the flight plan. So the "cushion of air" explains it nicely to the layperson. Those in aviation will of course understand what he meant.

Wow, exciting & well done video! I want an MD 900 NOTAR Explorer SO BAD!

Hello Mr. your English spoken is very fast please reduce your spoken speed .we are not a English persons please reduce your spoken speed thanks.

[@regwatson2017]

Only thing I didn't understand was how you were close to the 100% power limit in the first place ? Was it because of the fact that you were high up and the air is thinner ?

[@knarftrakiul3881]

I've seen a bunch of videos of helicopters loosing control and flopping over on their side when taking off and landing. What causes that? Wind?

[@alanckaye]

Great video. I watched your video on 2 main reasons helicopters crash. Are you saying too much power in certain situations is a crashable situation - very common?

[@LuizCma]

MUITO BOM, BRASIL OK.

[@justinbosboom8602]

Why do helicopters over pitch when hovering before landing but have plenty of power to go into a hover before take off. Seen plenty of videos of helis coming Into a hover and then overpitching it.
