g. Performance with an inoperative powerplant for all phases of flight (AMEL, AMES)
How to determine the following, as applicable to the class sought: g. Performance with an inoperative powerplant for all phases of flight (AMEL, AMES)
Bottom line
Performance with an inoperative powerplant includes the minimum control speed with the critical engine inoperative during takeoff roll (VMCG). It also includes the minimum control speed with the critical engine inoperative out of ground effect (VMCA). The performance of a reciprocating-engine-powered airplane with one engine inoperative must be determined by flight test.
