If you keep it at ARM, is it inactive then? Does it then only require the switch of the A/P to be turned to "on" to activate it? I assume the speed has already been dialled in at this stage? (Curious non-pilot here!) Is the AT operable ONLY with the A/P being ON, ie. it is coupled with the A/P, and can only be used witht the A/P? Or is it usable as a single operational tool? How often is A/T used, during which stages of flight for example?
Thanks again, LJ.
