BlenderPilot, it must have been a shock to see the other L3 go into LTE.
RVDT, I think there is a distinction between getting into LTE and getting out of LTE. Pilots get themselves into LTE by making mistakes but recognising LTE and taking timely corrective action is the real test. My discussion is limited to the remedial action after LTE has begun to set in.
I have experienced full LTE too and, speaking to senior instructors and other high-time pilots who have suffered LTE, an interesting fact emerges. No matter whether the spin set in slowly to start off with (like the Ecuador video) or happened suddenly and quickly, the only practical way to survive is to roll off throttle and (height permitting) reduce collective. I have yet to meet someone who managed to pull it off by flying away with cyclic and pedals.
