How about if you have the AP on when encountering turbulence.?
Do you disconnecr it and attempt to fly the aircraft or as I recall in other similar threads, most pilots leave it connected
It seems on the surface that the speed discussion seems to assume that the decision is reactionary after encountering turbulence, yet so is the decision above about whether to disconect the AP.
If you leave the AP connected and functioning why bother to change speed.?
