VMC Demonstration (AMEL, AMES)
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with VMC demonstration. Note: See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Bottom line
Maintaining altitude is not a criterion in accomplishing the VMC demonstration; it is a demonstration of controllability, not performance.
