Then there are some pilots who engage both autopilots in the 737 when doing an ILS in Cat 1 or better weather instead of just one autopilot. Their reasoning is that an automatic pilot go-around is available in case they have to go-around. The problem there is when they disconnect both autopilots after becoming visual and intend to land, they are faced with bags of back trim already set by the autopilot at 400 ft AGL and they have to hastily correct the ensuing pitch up that occurs with AP disconnect.
And all for what? The answer is they are worried about their ability to do a normal manually flown go-around.
