I have had DEEC engines surge with over-enthusiastic thrust lever closures at altitude.
The surge resulted in a BANG as the engine slowed.
Do you really want to be telling the FADEC "
This is an emergency! I need minimum power as soon as you can do it!" - or do you want to ease the thrust lever back, effectively telling the FADEC "
Hey, relax dude - this is a normal deceleration for descent."
Do you want to be training yourself to only be able to fly FADEC engines? .. or would you like to train yourself proper piloting techniques, so that you aren't reliant on computers correcting your poor flying?
(For those not as old as I am, DEEC = Digital Electronic Engine Control, a digital computer linked to a basic Mechanical Fuel Control - a "poor man's FADEC")
