What is the difference between Mel and CDL?
While the MEL describes the limitations of aircraft operation in case of a system being inoperative/having malfunctioned (e.g. transponder failure), the CDL deals with situations where external parts of an aircraft are missing/fallen off (e.g. fairings, aerodynamic seals or panels).
What equipment Cannot be listed on an Mel?
It may not include items like galley equipment, entertainment systems, passenger convenience equipment, which do not affect the airworthiness of an aircraft.
