Ah, the Air Asia 330. That was a horrifying bit of video. They flew away from a perfectly acceptable airport (Learmonth), for no good aviation reason.I was watching a video with that United twin which had engine issues/parts seperated and was shaking fairly violently on the wing. Also the AirAsia A330 which flew for hours with a vibrating almost ‘jumping’ engine on the wing.
My question is, if the engine gives way and falls off, what happens to the aerodynamics of the aircraft. Would it be expected to just spiral out of control, or is glide still available (although one wing more heavy)
If the engine is shut down, and just shakes itself off, as long as it doesn’t hit anything on the way, it shouldn’t cause any issue. Be a winner actually, as the ride would smooth out. There’s no reason for any control issues, or problems with gliding. An engine weighs a few tonnes, but that’s trivia in the grand scheme.
The problem would be a pylon failure with an engine running under power. The DC10 at Chicago showed us what can happen there, as it flew forward, and pivoted over the top of the wing, damaging the leading edge as it did so. At that point the aircraft was still flyable, but as the hydraulic fluid leaked out of the system, it allowed the leading edge devices on that wing to retract, and that resulted in loss of control. Knowing what I know now, there was a way of keeping control, but sadly the pilots weren’t to know.
