When do you turn on and off autopilot while in flight?
On:
I usually turn it on after the first target altitude of the SID I’m using or if there’s no target altitude in the SID I’d just turn it on after passing 7000ft MSL
Off:
I usually turn off the Speed function of autopilot just prior to turning base when landing. While I turn off the entire autopilot once I’m established on the localizer and glideslope and have armed the ground spoilers and extended the landing gear.
