This online training provides an insight into the Minimum Equipment List (MEL), which is a document that lists the equipment that may be temporarily inoperative under certain conditions at the commencement of flight. The MEL is prepared by the operator for their own particular aircraft based on the Master Minimum Equipment List (MMEL), taking into account specific variables such as operating environment, route structure, and geographic location.

The student learns how to identify the minimum equipment and conditions needed to safely operate an aircraft having inoperative equipment, with the goal of minimizing continued operation with inoperative equipment. The course also covers the Configuration Deviation List (CDL), which has the character of a supplement to operational limitations and indicates operation of the aircraft without certain secondary airframe and engine parts is possible.
