Bullethead,
Good idea. I've had the same philosophy, about guarding T/L's when large power changes are going on, even though it is not SOP in my airline. e.g levelling off from climb or descent. I've tried to educate cadets that not all airmanship is written in SOP's. Thus I encouraged them to follow through on the T/L's in such scenarios. They always asked Why? and didn't adopt it, saying the A/T was there to do that. Why then do you follow through on the T/L's when setting takeoff thrust with A/T engaged. OK, it is possible and correct that not both T/L's will reach calculated takeoff setting, hence hand at the ready. But a computer is a computer, and it can have a wobbly any time. The TMC is a fickle as any of them.
