What is the maximum time the taxi lights may remain on when the aircraft is stationary?

The correct answer reflects established protocols regarding the use of taxi lights when an aircraft is stationary on the ground. Keeping taxi lights on for a maximum of 10 minutes when the aircraft is stationary is important for several reasons.

This time limit helps reduce the risk of draining the aircraft's battery, as prolonged use of taxi lights can consume significant power resources. Additionally, adhering to the 10-minute guideline minimizes the chances of dazzling ground personnel or causing confusion at busy airports. This ensures safe operations while maintaining awareness around the aircraft's status on the tarmac.

Safety and efficiency in aviation are priorities, and this time constraint is a standard best practice intended to balance visibility with operational sustainability.
