What type of temperatures does the engine fire warning system primarily focus on?

The engine fire warning system in the T-6B primarily focuses on average and discrete temperatures exterior to the engine. This system is designed to detect conditions that may indicate an engine fire or an over-temperature situation, which typically manifests in the areas surrounding the engine rather than within the engine's internal components.

The system monitors the surface temperatures that could be indicative of fire hazards, as these exterior temperatures can rise rapidly in the event of an engine fire. By focusing on these external temperature thresholds, the warning system can provide timely alerts to the pilots, allowing them to take appropriate actions, such as shutting down the engine or executing emergency procedures.

Understanding that the warning system is not primarily concerned with internal engine temperatures, engine oil temperatures, or fluid temperatures helps clarify its specific operational focus on detecting potential fire threats through the assessment of external temperature readings. This distinction is vital for managing safety in flight operations effectively.
