What does the Configuration Deviations List (CDL) specify?

What does the Configuration Deviations List (CDL) specify?

• A. It lists equipment inside the aircraft that must be operable
• B. It describes changes to flight crew duties
• C. It documents in-flight failures
• D. It lists equipment outside the aircraft that may be inoperative and any penalties, used on the ground prior to takeoff

Answer: (D)

The concept tested is how configuration deviations are managed before flight. The Configuration Deviations List specifies equipment outside the aircraft that may be inoperative and any penalties or restrictions to be applied on the ground prior to takeoff. This lets crews depart with certain external items not functioning under defined conditions, without delaying the flight, while still ensuring safety and compliance. It’s different from lists that cover in-flight faults or crew duties; the CDL is focused on exterior equipment and the preflight allowances and penalties, not on in-flight operations. That alignment makes the statement describing exterior equipment that may be inoperative and any preflight penalties the correct one.
