What should pilots do as per the minimum equipment list?

The minimum equipment list (MEL) is a critical document for pilots that outlines the necessary equipment that must be operational for legal and safe flight. The correct action for pilots is to ensure that all items listed as required in the MEL are fully functional before taking off.

Understanding the MEL allows pilots to make informed decisions about whether to operate the aircraft safely given the operational conditions and the status of the aircraft's systems. If any critical equipment is inoperative, the pilot must adhere to the procedures specified in the MEL, which may include not flying until the issue is addressed or utilizing alternate procedures if permissible.

This focus on functionality is crucial because each piece of equipment contributes to the overall safety and performance of the aircraft. A comprehensive check of all required items helps in preventing in-flight emergencies and ensures compliance with aviation regulations.
