Discussion on the Key Points of PMMEL Working of Civil Helicopter
The civilian helicopter PMMEL is designed to ensure the ability of the helicopter to maintain safe flight and landing in the event of partial equipment failure.It is based on the design,operational experience,and safety requirements of helicopters,and lists the minimum equipment configurations that can be accepted in specific situations.The proposed master minimum equipment list(PMMEL)is the basis for the review of the master minimum equipment list(MMEL),and it will directly affect the safety and economy balance of civil helicopter operation.This article combines the main points of the PMMEL work with the experience of the civil helicopter model to provide meaningful reference for the development of the civil helicopter PMMEL.
