What is the typical engine-fire emergency procedure on the ground?

• A. Increase fuel flow
• B. Deploy extinguisher
• C. Cut fuel, shut down the engine, isolate sources, deploy extinguisher, evacuate if necessary
• D. Evacuate immediately without actions

Answer: (C)

When facing a ground engine-fire, the priority is to stop the fuel and shut the engine first, then manage energy sources, suppress the fire, and retreat only if the situation demands. Cutting fuel and shutting the engine halt the source of ignition and prevent the engine from continuing to burn or attempt to restart, which is crucial for stopping the fire quickly. Isolating sources means closing fuel valves and disconnecting or turning off auxiliary power and electrical systems that could feed the fire or keep damaged systems energized. Deploying the extinguisher applies a suppression agent directly to the flames, increasing the chances that the fire can be contained without spreading. Evacuating if necessary ensures crew safety when the fire cannot be controlled or if conditions become life-threatening. Choosing to increase fuel flow would fuel the blaze, and evacuating without taking suppressive and shutdown actions delays control and can put everyone at greater risk.
