What is the maximum operational time for the landing lights during ground operations?

The maximum operational time for the landing lights during ground operations is indeed 15 minutes with a 45-minute cooldown. This limitation is primarily in place to prevent overheating and potential damage to the landing lights, which are high-intensity lighting systems designed for illuminating the runway during landing and takeoff, rather than prolonged use while on the ground. Adhering to this operational timeframe ensures the longevity and reliability of the lights, providing optimal performance when needed for safety during flight operations.

The cooldown period allows the lights to dissipate heat accumulated during their use, thus preventing thermal stress that could lead to failures or reduced functionality. Understanding these parameters is crucial for aircraft operators and maintenance teams to ensure the aircraft is operated within safe limits, thus enhancing safety and performance during ground and flight operations.
