Leadsled:
Not limited to "directions to ATOs" that (asymmetric) handling of a "V1" cut ( no such thing on a FAR 23 aeroplane) "engine failure on takeoff" must be demonstrated by pulling the mixture ---- no wuzzy "zero thrust". This is at the heart of the problems of the ATOs, who, perhaps not surprisingly, have shown no enthusiasm for such bureaucratically directed "techniques".
If that is actually correct, then I'm simply flabbergasted. I only fly singles, but were someone to do that to me, the mixture control would be immediately returned to full rich and the test terminated.
I've had the throttle retarded to idle at fifty feet on takeoff, together with "Engine failure, what are you going to do now?" and even that focuses your attention.
