After how many minutes stationary must the taxi lights be switched off?

The taxi lights should be switched off after ten minutes of being stationary to prevent battery drain and unnecessary wear on the electrical system. This limitation is established to optimize the performance and longevity of the aircraft’s systems while ensuring safety. Keeping taxi lights on for extended periods can lead to excessive power consumption, potentially affecting other systems that rely on the battery. Therefore, adhering to the ten-minute rule encourages efficient management of the aircraft's resources during ground operations.
