Hi takata. No problem. In 447's case, it was not THS authority that was desired, it was the desire (seemingly unaddressed, or ignored) to defeat it, to zero it. The Elevators were fine, yes? GY points out DIRECT LAW was not in. If TRIMMING can get the a/c into trouble, (fbw, or not
), it should have a Zero channel, no?
This is what I need to know. It is said the THS follows the Pilot's ss input.
This isn't emergency; on the way up, it was doing NORMAL LAW stuff? Given the dire nature of the a/c assiete at top of climb, How could the lack of Power to the THS be the reason it stayed at ~13 NU? It appears at this point, that the climb was a problem (!), independent of conjecture re: the accident, With a need for STALL recovery, and the THS limit of 2degrees ND, no matter the reason, how did she abandon the THS so NU?
This is a big question for Pilotless flight, notwithstanding whatever 447' PF did or did not do?
Thanks again for your pics, and wow. (words of wisdom)
edit re: upper post. Manual Trim was required, isn't that .65 degree per "hand sweep"? Also, in active dynamic flight , (UA recovery), power and rate are not desired coupled together? Q/N, (Quick and Nasty?) Cruise flight wants those tender touch, Yes?
