Is it possible then that the autopilot was not sufficiently rapid to keep control? (447) What happens when 330 Auto can't be so quick as your Viper?
What happens if roll rate for gums is too slow by half when one slat fouls?
What happens to 447 when auto is too lazy? airplane is an airplane?
F4 For two years, no progress has been made on either side. You and smilin have nailed the problem each time, and each time it is ignored by "The a/c did what was directed."
It also did what was directed, apparently, by NOT trimming whilst the a/c was in an aspect commanding certain g. So if the Autotrim is disabled when the airframe is under maneuvering load, whty does it return "automatucally" (at the top of the gd climb, of all places), to seal the fate of the pilot who probably couldn';t have recovered anyway, even knowing the Auto trim was active?
Don't be sly, messrs. AB. Whether the pilot knew or did not know the Autotrim was active may well have been irrelevant. "Red Herring"? A "helpful" Gremlin in the tail cone, with a prod to mystify the crew? Changing the handling of this airframe in ways not EVER practiced by the humans?
