You either maintain controlled flight and have some influence over where you crash or you don't.
And that is the point.
But regardless of what the engine instruments are saying, the control inputs will give a significant clue as to what is happening. Dead leg, dead engine?
From the radar track it looks like they never got on top of controlling the flight path neither horizontally nor vertically.
I'd go so far as to add a further '-ate'.
Aviate
Navigate
INVESTIGATE
Communicate.
