pulling the throttle back to control the airspeed is basic flying just as trimming the aircraft.
Trimming. Now there's an interesting concept. Let's see. AP on at 500ft after takeoff. No pilot trim required. AP out at 500ft on final approach. No pilot trim required. In some companies, this is the recommended/preferred SOP.
How is a pilot expected to instinctively trim in such a diabolical scenario when he doesn't do it at any other time?
