What is the first action to take if there is a brake/wheel tire fire?

In the event of a brake or wheel tire fire, the priority is to ensure the safety of the aircraft and personnel involved. Signaling the pilot is essential because it alerts them to the situation and allows them to take necessary precautions, such as moving the aircraft to a safer location or shutting down engines to limit potential hazards.

This action serves as the first line of defense in a fire emergency. The pilot's awareness can initiate additional emergency protocols and facilitate communication with ground support for firefighting resources. Timely signaling can also prevent further escalation of the situation by ensuring that the pilot is informed of any immediate dangers.

The other options involve actions that could either delay the appropriate response or present additional risks. Approaching from the front may place personnel in jeopardy, especially if the aircraft is under power or the fire is more severe than initially assumed. Using a foam extinguisher directly on the tire should only occur with the pilot's approval due to safety protocols, and increasing engine power would exacerbate the issue, potentially leading to a more dangerous situation.
