What is the first step to take when alerted to an engine fire?

When alerted to an engine fire, the first step you should take is to perform a proper hand signal to the pilot. This communication is critical for ensuring that the pilot is informed of the emergency situation and can take the necessary actions to secure the aircraft. The hand signal serves to quickly inform the pilot of the fire and initiates the emergency response protocol, enabling both the pilot and crew to coordinate their efforts effectively.

While shutting down the engine, injecting an extinguishing agent, and disconnecting the battery are all important steps in the sequence of actions to address an engine fire, they come after ensuring that the pilot is aware of the situation. The pilot must receive immediate notification so they can respond correctly, prioritize safety, and manage the emergency effectively.
