explain the "auto throttle" to me/us
From the Asiana threads, I am not sure how the "auto throttle" really works, or even the intent.
If the thing is set to hold an airspeed and change the engine thrust to hold that airspeed, then sounds like what we USAF pilots usually flew. You know, point the nose and move the throttles to hold speed. The nasal radiators did it different. Hold an AoA that gave you best approach speed for weight and such, then move throttles to control rate of descent. We SLUF ( A-7D) pilots found that the Navy procedure was great, but we still did a slight flare just before touchdown as we were not trying to catch a wire on the deck of a pitchin/rolling boat.
The Asiana crew appears to have used the procedure/technique we USAF dweebs used - point the jet, and move throttles or let HAL move them.
I would appreciate some explanations and rationale for different implementations.
