Up till now my company SOPs dictate the A/T to be armed at all times, but now there will be change to the official Boeing procedures - including A/T disengage for manual landings. My two cents: I am a bit distrustful, A/T go-around is a very good thing, anything to reduce workload at low altitude is good - setting go-around thrust manually is a pain, and to my knowledge the 'tailstrike due to autothrottle intervention' is purely anecdotal, can someone shed some light on this?
