Hi James7, thanks for the comments. You are right regarding the old generation (737-2, 727, 737-3, etc...), but I currently fly the B777 and the A/T stays ON ALL the TIME up to touchdown, the same with the B747-400 in my last company. Another example is the MD11 that also lands with the A/T ON all the time. In all the mentioned aircrafts, the A/T system retards the thrust levers to idle at around 27Ft RA. I may be wrong regarding the 757 and 767.
Regards
