Speed-Power
Dalek , Walter...
..just one small point here.........
..there were no power levers for the engines.........
..the whole point of FADEC is to allow the engines to respond by themselves to any need for more or less power.....in order to maintain rotor rpm within the critical range.....
..there was no evidence that full emergency power was ever used , as it starts a counter to record the fact if sensed for more than one second........
