What should be turned OFF for a wing fire emergency situation?

In the event of a wing fire emergency, the primary focus is on reducing the risk of further igniting the fire or exacerbating the situation. Turning off the land and taxi lights is crucial because these lights generate heat, and since the fire is occurring in the wing area, any additional heat source could worsen the situation.

By switching off the land and taxi lights, you minimize any risk that could further fuel the fire or cause additional complications during the firefighting process and emergency landing preparations.

The fuel pump, while also essential to consider, is managed based on specific training protocols for such emergencies, and while it may be turned off in some procedures, other options are more directly associated with reducing heat. The airspeed indicator and altitude transponder do not pose risks directly related to the fire itself, making the choice of turning off the land and taxi lights more relevant to managing a wing fire scenario effectively.
