Recently I've had a few textbook landings ruined because when I turn off the autopilot just before the wheels touch the aircraft starts banking and veers off from the runway. The reason for it is because in previous flights I have altered the aileron trim and its not been reset. Even though I have a key that centers the rudder and ailerons it doesn't reset the trim setting? Is there a way I can reset it completely. The graphical display of my ailerons position isn't very clear either and there is no digital display so centering them manually involves a bit of guess work.
All this has happened because I've started banking the plane with the ailerons manually instead of letting the autopilot do it and I've not checked the trim settings in subsequent flights. In the real world when vectoring an airport do pilots use the AP to manouver and let the AP systems handle all the trim settings?
