Lost in Saigon: During the Takeoff roll A/T comes on at 80kts and generally stays on until after landing.
Really .... Then what kind of strange magic advances the thrust levers to take off power when you press TOGA prior to the aircraft moving an inch ?
lost in Saigon: You can "click off" the A/T by pressing a button on the control wheel but it remains armed and will come back on
There is no button on the control wheel that "clicks off" the A/T.
