ACS element text (the applicant demonstrates understanding of)

Reduce drag by retracting landing gear and flaps in accordance with the manufacturer’s guidance.

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. 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. After the flaps and landing gear have been retracted and the propeller of the inoperative engine feathered, a key element in extracting best climb performance is minimizing sideslip.
