Is it easy/possible to restart an engine during midflight high altitude cruising should a pilot incidentally touch the cutoff button for FF? i was watching the VS744 video last night put out by ITVV and it crossed my mind. Thanks in advance for any answers....Joe
Unitentional shutdowns are highly unlikely though, at least for the reason you noted. I'm not aware of any aircraft that has a cutoff button. Cutoff levers are 1) placed in a position which would be very difficult to accidentally 'bump', and 2) require two steps to place the lever in cutoff position. Typically you have to pull the lever outward from its detent before lowering it. Unless you're purposely trying to do it, you'll get a punch in the face from someone in the cockpit long before you shut down the engines.
Now if you err in judging which engine is on fire and you accidentally shut down the wrong engine.....which has happened.......
During the flight testing phase for production aircraft, they test engine re-light in flight.
Apparently (don't know if this is true!) the brave ones try to relight both at once instead of doing one after another (i.e. leaving one on at all times)!
