Demonstration of Effects of Various Airspeeds and Configurations during Engine Inoperative
To determine the applicant understands the effects of various airspeeds and configurations during engine inoperative performance, can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction. Note: See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Bottom line
There is a dramatic performance loss associated with the loss of an engine, particularly just after takeoff. VMC only addresses directional control; there is no requirement that the airplane be capable of climbing at this airspeed. Performance speeds vary with aircraft weight, configuration, and atmospheric conditions.
