Engine fire detection sensing elements are located in which of the following locations?

Fire detection sensing elements are placed in multiple zones of the engine to ensure any fire is detected quickly, no matter where it starts. Placing sensors in the engine core targets fires in the hottest, most fuel-rich area where combustion could begin, so an ignition or flame can be detected early. Sensing elements in the accessory gear box monitor that region where oil, lubricants, and heat from rotating equipment can fuel a fire if leaks or failures occur. The fixed cowl sensors cover the outer nacelle space, helping to catch fires that may be developing on or around the engine’s exterior or in the ducting between the engine and the nacelle. Using sensors in all these locations provides broad coverage and redundancy, so a fire anywhere within these critical zones triggers the warning and the associated suppression systems promptly. In short, multiple sensing locations ensure rapid detection across all areas where an engine fire could plausibly start, maximizing safety and response effectiveness.
