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).
Can an aircraft be legally operated with a known inoperative equipment?
The answer is, yes, we can continue to operate the aircraft with inoperative instruments and/or equipment as long as it is done within the provisions outlined by 14 CFR Part 91.213.
