737 A/T ARM mode
Why Boeing didn't recommend the A/T to be armed during landing (deselect the existing) rather disengage the A/T? Doing this will let the auothrottle advance automatically to go around thrust during a single go around.
Q 2. I understand the A/T ARM mode provide underspeed protection, but why during takeoff mode thrust goes to THR HLD instead of ARM? If the mode would be "ARM" will this make the thrust to advance again in case of a rejected takeoff? If so, why? where is the "underspeed" in this situation?
