Quote: "Lagos was a short stop to board some pax. The crew failed to arm AT before departure. On takeoff, pushing TOGA didn't engage AT (because, it wasn't armed)."
So why were the autothrottle arm switches off? There is no reason to turn them off and particularly as the aircraft was on a transit stop anyway.
But even on a normal turnaround or long nightstop there is no reason to turn the auto throttle arm switches off. There is no Boeing procedure that calls for them to ever be selected off on the 777 (except in a non normal or engine failure type event)
