I would think so, yes. Trim seems to be a counter intuitive goal when attempting a recovery? It implies that any particular attitude is worthy of continued authority. I am trying to picture how Trim is important to upset recovery (or in turbulence), when it is critical for allowing aft cg flight for economy? If relied upon to sustain an otherwise laborious aspect (tail 'lift'), it is also reliable to command inputs that may be more transient than the word 'trim' would imply?
Especially in recovery, as here with 447, with the THS NU within one degree of max., if the turbulence changes, one is stuck with max trim up. Just trying to get a handle on the challenges the PF was facing at a/p loss.
