In the case of a wing fire during flight, what should you do with the nav lights?

Turning off the navigation lights during a wing fire is critical for several reasons. Primarily, navigation lights produce heat due to their electrical components and can potentially exacerbate the fire. By turning them off, you are minimizing any additional sources of ignition or heat that might contribute to the worsening of the situation.

Additionally, during an emergency situation like a wing fire, the focus is often on achieving a safe landing and maintaining control of the aircraft. Having the navigation lights off can also help in reducing the electrical load on the system, ensuring that the essential functions of the aircraft are prioritized.

In contrast, leaving the lights on or set to flash would keep electrical components engaged, which could be detrimental when trying to manage the situation effectively. Overall, turning the navigation lights off is a precautionary measure to help ensure the safety of the flight crew and the aircraft.
