Hope you have a tin hat DA !
This thread is like an echo from the edge of the universe, back to deep stall and THS authority. There was a mountain of stuff on this in Tech Log Thread #4 including (916),
"If THS > 8 up (and no autotrim available), full elevator pitch down authority may be insufficient for speeds above 180 knots."
...at reasonable attitude of course. However is the distinction between stall, deep stall relevant as no apparent sustained attemp at ND is evident, less that it was wanted but the THS frustrated it. Back to Tech Log !
