What does it take to get out of hibernation?
CONF iture;
The "influence of the THS" argument has been demonstrated as a non-starter. The aerodynamic argument has been examined by Owain Glyndwr to which reference has been made before.
For lack of better words, it seems this is pushed quite a bit far out of context.
The aircraft remained in the stall because of the predominantly NU stick position held in by the PF, and not due to the position of the THS.
I have great respect for the mastering of a careful and well thought out writing in posts carrying your signature, and the surprise to see an exception has certainly been a wake up.. .
You're not saying that the HS has no contribution to the NU are you? But it reads that way.
The A/C remained in stall because of the sum of the effects of ALL the aerodynamic contributing factors to a prolonged NU, of which HS is part of. The NU stick drove the automatic move of the HS to MAX NU. If the NU stick would have had no effect on the THS - if the HS would stop moving at STALL condition detection - that would have removed the HS from the contributor factors. But that was not the case.
CONF iture is absolutely right that this should be documented well by any analysis, or technical report.
