IF789 I am NOT suggesting AutoTrim 'dropout'. That is a bad idea. It should not have begun in the first place, but once present, an immediate loss of AoI aspect could be deadly.
If THS dialed in NU to accommodate PF input, there is a big problem with that, and the main reason recovery most likely was impossible. The fact that PF did not recover the flight Path is not relevant for the general discussion.
If THS was loading NU to re-gee the airframe, same story, it was out of its program, functionally. The a/c had to have ND, and just cause the PF didn't grok that, it is ok for the THS to blow it also?
At the onset of climb, PF had elevators loaded with airstream, and THS was unnecessary. He was barred from over loading the tail via 'g' protection, but that wasn't necessary either. He was allowed (or input himself) nibbles of NU sufficient to STALL. Because it took so long to STALL, he had zippo energy (~ or, 'not enough') left to allow a rapid break, and the MUSH brigade began. Now without cue, no-one gets that the airframe is STALLED, and TOGA is still proper (in the BOOK) per procedure, Bob's yer uncle. Done, done, done.
REPEAT... I do not advocate 'dumping' trim in the guise of recovery.
per LATCH AL2. Why do we have to go back to NORMAL LAW from AL2?
How about just a simpler version of it, like an autopilot. Is that to Ludditic?
