Flight characteristics and controllability associated with maneuvering the airplane with powerplant(s) inoperative, including the importance of drag reduction.
Bottom line
Controllability is the capability of an aircraft to respond to the pilot's control, especially with regard to flight path and attitude. A windmilling propeller has, in many cases, given the improperly trained multiengine pilot the mistaken perception that the engine is still developing useful thrust. The aircraft drag defines the thrust required to maintain steady, level flight.
