What triggers the Fire Warning Light to illuminate?

• A. When fuel flow exceeds normal limits
• B. When the oil pressure drops below a certain level
• C. When the temperature in the engine cavity reaches an overheat condition
• D. When the engine is started

Answer: (C)

The Fire Warning Light illuminates primarily in response to conditions indicating an overheat situation within the engine cavity. This feature is critical for ensuring safety, as it alerts the crew to potentially hazardous temperatures that could lead to a fire. When the temperature reaches a pre-defined threshold that signifies a risk of combustion or fire, the warning system activates the light, prompting immediate attention and corrective action.

In this context, monitoring the engine cavity temperature is vital for maintaining operational safety. Engineers and pilots must stay vigilant for any indications of overheating, as failure to address such warnings can result in severe consequences, including damage to the aircraft or jeopardizing safety.
