Trim is a function of Airspeed and not attitude
Could you explain more?
e.g. Power & Pitch = Performance ...the golden rule of attutude flying.
Trim an aircraft to an airspeed without considering pitch/power and surely you do not necessarily get the required performance ... just accurate speed control.
e.g. trim to approach speed with too little power and you get excessive sink - you land in the undershoot unless you correct.
Therefore shouldn't we set the attitude (picture), set the power to give us the airspeed and sink rate required to maintain the glidepath and then trim to remove the control forces so that the aircraft is stabilised?
