If two aircrews do not complete the required checklist entries, what action should they take?

Completing the required checklist entries on the ground is essential for ensuring the safety and airworthiness of the aircraft. Checklists are critical in aviation as they provide a systematic way to verify that all necessary pre-flight and operational procedures have been followed. This step is crucial for identifying any potential issues before taking off.

By completing the checklist entries before departure, the aircrews can confirm that the aircraft is in the appropriate state for flight and that all safety protocols have been adhered to. This action helps mitigate risk and ensures compliance with regulations and standard operating procedures. Taking this step on the ground allows for any discrepancies to be addressed without the added complications and dangers of being in-flight.

Other choices such as leaving the aircraft or requesting permission to take off do not address the underlying issue of incomplete checklist entries, which could compromise the aircraft’s safety. Reporting to the maintenance crew may be a necessary action if discrepancies are found; however, completing the checklist beforehand ensures that all standard procedures are fulfilled.
