The Kite,
sorry , shoddy explanantion, I mean sitting there with the collective still up - AFTER - the engine has hypothetically quit.
He relays that he has this very BIG (roll the eyes now) clock on the panel which indicates ~ and records for the big time FAA boys ~ just how quickly, or slowly, he puts the lever down.
.98 seconds delay , easy, the regulation one full second, not so easy.
cheers tet
