I C - absolutely, but the imponderable with the 'Boeing' teaching was that if you bugged your 'chosen' Vapp with A/T engaged in gusty/windy conditions, the kit would probably be flying you faster than bug and when you do 'disconnect' you would be faced with a power reduction to achieve bugged speed, hence my choice of manual thrust and fly what I want.
Oh yes, as 'C' says, do NOT over-ride the A/Throttle except in an emergency. Like any 'automatics' - if they are not doing what you need, take them out, don't fight them. NOT good teaching!
