A constant severe vibration can cause the player to glitch or fall over completely. ...
we have seen this happen with some aviation installations.



I would have to say, that if your Empeg falls over due to coninuous vibrations or turbulence whilst installed in your airplane.
Then I hazard a guess, that listening to music is probably the last thing on your mind!

If it happened to me, I would probably be reaching for the either the vomit bags or the parachute - whichever was available!
