When cold fueling an aircraft, how long is the maximum wait for the pre-check?

The maximum wait time for the pre-check during cold fueling an aircraft is 45 seconds. This time frame is established to ensure that fueling operations are conducted securely and efficiently while maintaining the safety of both personnel and the aircraft.

The pre-check is a critical safety measure that involves verifying safety standards, equipment checks, and ensuring that all personnel are in a safe position before fueling begins. If there are any concerns or issues detected during this pre-check period, exceeding the 45-second guideline could indicate that something is wrong that needs immediate attention. Adhering to this duration helps maintain a high level of safety and operational integrity in the fueling process, minimizing risks associated with fueling operations.
