Sorry, my bad, I meant push the stick forward to arrest the climb, and yes @Idle Wild you can make slight corrections to flight path in the Harrier with AFC on. Yes AFC is still on, and it will start drifting again.
@lukeXIII Not being a jerk, serious question: Why should I need to increase my deadbands when the AFC has worked fine for a year and a half at their current setting? That tells me something has changed.
