Configuring the airplane.
Configuring the airplane.
Bottom line
Drag from a windmilling propeller, extended landing gear, flaps extended beyond optimum, or any sideslip will reduce or even eliminate any modest single-engine performance that may exist. A windmilling propeller, in many cases, has given the improperly trained multiengine pilot the mistaken perception that the engine is still developing useful thrust, resulting in a psychological reluctance to feather, as feathering results in cessation of propeller rotation. The actions listed in the “Engine Failure After Takeoff ” checklist in this pamphlet should be promptly executed to configure the airplane for climb with minimum drag.
