It was not known to me, and I appreciate rudderrat's rephrase. I'll be brief with my next question. Of course it may (is) in the FCOM, but may I see any answer in the thread?
If frozen, the THS would be unavailable for Trimming, (or Pitch changes), until what point? When does it become available again?
So the original question remains: If less than one g, does the THS move independently of Pilot's inputs? Does it try to regain 1g or satisfy itself that anything greater than -1g is acceptable?
Does it "Unfreeze" if the g becomes <-1g? And then input NU?
The limits are intriguing to me, until I have a better picture of what the THS may have been doing in <1g, who can say what the a/c's behaviour was?
To expand on BOAC's #2, BEA have not assigned the climb to the pilots, that is true, and they affirm that by specifically stating, "ONE" (a) Noseup, left roll input. That apparently happened prior to the "climb", as I read it.
