The Forbidden Maneuver in Commercial Aviation - The unbelievable crash of a Yak-40 in 1986

It’s a well known story in aviation that, in 1955 Boeing test pilot Tex Johnston performed a barrel roll with a new 707. During the roll a +1 g acceleration was maintained, allowing for the famous pouring a drink while inverted. The trick is in the pilots skill and knowledge of aerodynamics. This accident seems to fit perfectly with pervasive macho attitudine in Russian colture.

[@bobharrison7693]

That was not a barrel roll, that was an improperly executed aileron roll. If done by the numbers, it is not a particularly dangerous maneuver. 1. Pitch the nose up (the pilot didn't pitch up at all), 2. RELAX the back pressure, and 3. apply maximum aileron in the direction of the roll. It takes a surprising degree of nose up attitude for a plane with a slow rate of roll as once the back pressure is released, the nose will drop towards the ground all the way through the maneuver. The next major mistake some pilots make is to not relax the back pressure on the yoke when starting the roll. That turns the maneuver into a sort of barrel roll with the nose pitching all through the maneuver such that as the aircraft reaches the inverted position half way through the maneuver, the pilot is actually pulling the nose towards the ground, resulting in an extreme nose down attitude as the roll is completed. This mistake likely caused the loss of a Navy EA-6B on a low level training flight near Spokane some years ago.

[@puppets.and.muppets]

nonsense.

[@ronanstis6328]

Bob is correct - at no time should the load on the aircraft exceed 1.5 G. The pilot should know the correct entry speed, (I'll bet it's not in the flight manual!) and ensure that the aircraft is at that speed before lowering the nose a little in a left bank for a right barrel roll. The nose is then raised while the aircraft is rolled to the right, not about its axis, but along a horizontal corkscrew flight path, finishing in level flight. You do not point the aircraft at the ground, and you do actually lose some speed during the manoeuvre. Correct use of rudder is just as important as aileron during the manoeuvre, in order to keep the nose aligned with the flight path.

[@warringtonminge4167]

I think - not being a pilot or even student of aviation - I get the difference between an aileron roll and a barrel roll. Is an aileron roll a roll with the aircraft spinning round the same "string" line of flight whereas a barrel roll involves rotating round inside a mythical barrel at a constant radius from the "string" which is the nominal line of flight?

During my airline career (UAL), most of the simulator check rides would have a few minutes of time left over at the end, and the check pilot would ask what we would like to do. I'd always go for a few aileron rolls. Done in the B727/B737/B757/B767/B777. The secret was to get the nose well above the horizon (~30 degrees), crank in full aileron and then neutralize the elevator once the pitch up was established. I always tried to come out a little higher than I started. Just like in the Globe Swift I owned. During training the instructor gave me a unannounced roll upset at about 10k feet. As the sim went through about 120' bank, and I had no idea why, I just "went with the flow" and finished the rather sloppy roll. Lost some altitude bur did not exceed barber pole or G limits.

I have been a commercial pilot since 1970. A Barrel Roll is far from being the most dangerous maneuver in commercial aviation. In fact it’s one of the simplest and less stressful acrobatic maneuvers in aviation. The reason this one caused the aircraft to break up is because the pilot did not do it properly. It’s a maneuver that when done properly should not produce more than 2 to 3 Gs. Many acrobatic pilots do it with only 1 to 1.5 Gs and no less than .5 Gs. Two to 3 Gs should not have caused the aircraft to break up. Granted the pilot should not have attempted the maneuver, as I’m sure the airline prohibits acrobatic maneuvers.

Mind you during the days of the USSR most of their pilots came from air force training which was notorious for reckless bravado.

You keep the coordinated turn going and pull back on the stick to keep 1 G. Keep turning and pulling 1 G until you are at right knife edge, then start forward on the stick until you turn to wings level. If you do this continuous coordinated turning at the correct rate you will end up about 30 degrees nose low. If you start about 30 degrees nose high you will end up wings level. Passengers with their eyes closed will say you just did a coordinated turn. A roll involves using the ailerons only and the aircraft rolls around a line going straight thru the fuselage.

He could have easily aborted the maneuver at 90 degrees of bank when it was apparent things weren't going well (but it takes an aerobatic pilot to recognize that). Starting the roll at 5 degrees nose up isn't nearly enough for a barrel roll in that type of plane, not even for an aileron roll. The aircraft is perfectly capable of those maneuvers, but the pilot was not. The B-707 has performed barrel rolls before without any issues. If performed correctly, it produces no more stress than a normal steep turn. Heck, Bob Hoover did them at airshows with both engines feathered while pouring a glass of water.

A barrel roll is certainly NOT a dangerous maneuver. And if executed correctly, the g force is at 1 G all through the roll. And - still if executed correctly - the nose would NOT drop below the horizon, so the aircraft would NOT gain speed. If the crew would have done a barrel roll, they'd have been fine.

[@ats-3693]

Not saying this wasn't totally reckless but a barrel roll isn't just rolling the aircraft around its own long axis, that's an aileron roll. A barrel roll is flying in a spiral both rolling and turning the aircraft around on the surface of an imaginary tube, which is the "barrel" If done correctly a barrel roll is a 1 g manoeuvre and doesn't put excessive stress on an aircraft, it's definitely not the most dangerous of aerobatic manoeuvres.

[@jepolch]

Beautiful animation. Why not put some characters in the cockpit?

[@planesounds]

Others may've said this, but a correctly executed barrel roll performed by a competent and experienced pilot is not a dangerous maneuver. In fact, it can be done such that even when carrying passengers, unless they were looking out the windows at the time, would not be aware that they had been inverted. However, you can be darn sure that every year some wannabe aerobatic pilot will kill themselves and a passenger that they were seeking to impress by trying it with no safety margin. Surely the Yak 40 was built to go beyond 5G? It was probably exceeding the Vne in an asymmetric attitude that tore the wing away.

A barrel roll if performed properly is not really all that dangerous

[@lxxsxxx7845]

The main inconsistency in this video is that the pilot never performed a barrel roll. He did what the video showed, only an aileron roll, defined as "complete roll of the aircraft around its own axis". May I add "longitudinal axis" for clarity and completeness? And the proper way to perform a barrel roll is to dip the nose to gain some airspeed, pull it up to nose-up pitch and start the roll with FULL aileron deflection (and sufficient rudder input). The aircraft will likely end up in a slightly nose-down attitude. Starting nose-up prevents too much nose-down during the maneuver and thus prevents rapid build-up of airspeed. Aileron rolls are very easy (I have done plenty). The higher the roll rate, the lower the pitch change, the lower the airspeed increase and thus the easier the recovery. Aerobatic aircraft have purposely high roll rate. Commercial airliners do not. A barrel roll in an airliner is doable. An aileron roll need a really good pilot with good aerobatic skills.

With a straight-winged aircraft at that altitude? Nobody considered its flight envelope? Getting to 90 degrees and being well below the horizon seems like a good time to abort the maneuver, but instead they doubled down.

[@jozsiolah1435]

About 30 barrel rolls are needed for Android to turn on a secret autopilot, that avoids a crash. Windows needs 20 fast dives that end up with crashes, after that the plane will be driven safely. The Russians may have done this deliberately to fix their autopilot, and to put it into another plane.

[@yves3560]

The barrel roll is by far not the most dangerous figure. It has been done with a boeing 707 on a demo flight for potential customers, the boeing company was not too happy with that, there was a picture taken from the cockpit while the liner was upside down.

[@stephendavidbailey2743]

Anyone know what the simulator is? Looks very sharp.

[@ProJanitor]

Would the plane have been able to perform that at a much higher altitude?

[@margarita8442]

a 707 did one at an airshow -- 1 G manouver

[@prettigedag]

Doing a barrel roll after doing some gentle turns is like an old man taking a walk around the block and then trying to do a floor exercise like an Olympic gymnast. Not gonna turn out well. The barrel roll, however, should not have produced 5Gs. It’s a one G maneuver.

[@WardinaAfikah]

They maybe be seen a barrel roll by 707 test pilot and though they can accomplished it too

[@renatorodrigues1189]

what´s the name of the simulator?

[@maxenielsen]

A barrel roll isn’t a dangerous maneuver.

[@es7821]

Russia at it’s best

[@ДжонПартлов]

if executed correctly a barrel roll will never seed one and a half gs This is not a dangerous maneuver if performed correctly. Look at text Johnson performing a barrel roll in a 707 in front of Boeing executives. to perform this maneuver properly, you would’ve first pulled the nose up, slowing airspeed, You would’ve never brought the nose down at one point during the barrel roll and should’ve lost air speed.

[@ДжонПартлов]

Exceed*

[@ДжонПартлов]

This is simply a case of a pilot not knowing what the hell he’s doing

[@donaldsalkovick396]

3 engines on a plane of this size?

[@malcolmwhite6588]

What’s more amazing is that there is stunning close-up footage of the whole test flight so that we can see exactly what happened

A barrel roll is NOT a dangerous maneuver if it is done correctly. But when you start it in a dive it will probably kill you ...

[@billiebobbienorton2556]

Captain Putin, can we go now?

[@bricefleckenstein9666]

If you do it right, it's not dangerous. Shown by a Boeing 707 almost 2 DECADES before this.

[@briancarno8837]

in a commercial airline would a barrel roll not mean all the dust, debris cigarette butts (this is Russia) etc swirl around and make a mess of the cockpit?

[@hj8272]

Why that soviet wheelbarrow needs three engines for 32 passengers? Oops, soviet technology.

[@TheBeingReal]

In Mother Russia: nothing ever goes wrong.

[@ronduncan9527]

Why are they doing maneuvers for a repaired nose gear?? And why are they banking the aircraft to 50° which is some thing you would never do in flight?

[@davidpp330]

I cannot think of any real world flight with passengers you would need to do a barrel roll so there is no reason at all for the Captain to try that maneuver! He is at fault and killed the crew with him!

[@roberts.3712]

That was really stupid.

[@CairnTerrier69]

I’m sure these guys and the two knuckleheads who attempted to climb an empty CRJ to 45,000 feet would have a lot to talk about. Rule of thumb…just do what you are supposed to do and save the “fun” for an appropriate aircraft or the simulator.

[@williampotter2098]

He fell out of the bottom of the barrel roll. So easy to do that. It is a difficult maneuver.

[@Madskills810]

not a dangerous maneuver just terrible pilots

[@rubiks6]

The left wing breaks off. wow. Stupid pilot.
