rendelharris Posted September 17, 2018 Share Posted September 17, 2018 And a complete spoof - I'm no expert but pretty sure that the first thing you would get on turning a jet airliner upside down is an instant rapid plunge downward of several thousand feet, or in this case about a hundred feet before the ground intervened!

Invert an airliner and once it's upside down, all the aerodynamics that were forcing it upwards start forcing it downwards instead.

fishbiscuits Posted September 17, 2018 Share Posted September 17, 2018 It's a fakehttps://www.aviation24.be/website/facebook/fake-video-beijing-capital-airlines-airbus-a320-accident-reached-6m-views-facebook/As for whether flying upside down is POSSIBLE in an airliner... it should be in theory. After entering the roll, you'd have to press forward/down on the controls, as if you were performing a dive, in order to keep the nose up. But of course an airliner isn't designed to be flown upside down, and doing so might place unusual stresses on the structure. Modern planes have software preventing the pilot over-stressing the plane, so in practice it might not be possible.There are some accounts of airliners performing barrel rolls... usually accidentally, but at least one intentionally, famously in a prototype Boeing 707 over Seattle.

rendelharris Posted September 17, 2018 Share Posted September 17, 2018 I remember seeing a documentary about Concorde where a test pilot said he and his French counterpart had barrelrolled it both ways, so it can be done - but not a hundred feet off the ground!

DulwichFox Posted September 17, 2018 Author Share Posted September 17, 2018 This was not a deliberate stunt performed by the pilot in stable air. This was an aircraft hit by the storm force of a Typhoon.

DulwichFox Posted September 17, 2018 Author Share Posted September 17, 2018 Well yes. The aircraft does appear to have no windows.. Give away. The point was that it was never claimed to be a stunt. It was mearly for intertainment value. I bet you lot call out the punchline and heckle at a comdey night.

Yeah it freaked me out when I first saw it too.The other giveaway was the passengers disembarking - from a completely different plane - in clear weather!

JohnL Posted September 18, 2018 Share Posted September 18, 2018 LOL you turn your airline over - set the aerofoils so you are flying upside down perfectly - then realise the fuel inlets at the fuel tank are at the bottom of the plane DOH.

Chick Posted September 22, 2018 Share Posted September 22, 2018 No. It depends on the angle of attack, as long as air is moving faster over the top of the wing there will be lift and the plane will keep flying.> Yes, I believe they frequently have asymmetrical> aerofoils (get me!) so they fly the same level or> inverted.

Pretty sure that's how it works. So if the wing is inverted, the air will be flowing slower under the groundward side and faster over the top, pushing it down?Mind you I'm an English graduate who doesn't really understand why electricity doesn't fall out of empty sockets, so could well be wrong!

Alan Medic Posted September 23, 2018 Share Posted September 23, 2018 I was following posts on twitter during the typhoon as my son is in Shenzhen and this was posted there and who knows where ever else. It's like a scene from the comedy movie Airplane.

As you stated, the wing deflects air downward. When inverted, the pilot simply controls the the pitch of the aircraft to keep the nose up, thus giving the wings sufficient angle of attack to deflect air downwards.It's less efficient and in a light air craft it requires full power.It would mean pointing the nose towards the sky. Hope that makes some sense.
