The abbreviation CDL refers to which of the following terms?

• A. Configuration Deviation List
• B. Configuration Deviation Ledger
• C. Compliance Deviation List
• D. Configuration Documentation List

Answer: (A)

Configuration Deviation List is the term used to document approved departures from the standard aircraft configuration and the conditions under which those deviations are allowed. It tells pilots and maintenance exactly which inoperative or missing items are acceptable for flight, and it specifies any limitations or procedures that must be followed during dispatch. This helps ensure safe operations by making explicit what can be altered in the aircraft setup and what the crew must do to operate within those allowances. The other phrases aren’t the standard terminology used to describe this concept, so they wouldn’t convey the approved, operationally safe deviations in the same way.
