Abstract
An aircraft-mounted external fire detection system includes optical circuitry and processing circuitry. The optical circuitry is mounted on an aircraft forward of an engine nacelle of the aircraft, and is configured to optically monitor an exterior of the engine nacelle for a hydrocarbon fire by detecting radiation outside of the visible light spectrum. The processing circuitry is communicatively coupled to the optical circuitry and is configured to use the optical circuitry to determine that the fire has been continuously present for more than a threshold duration, and in response, transmit a warning to an operator terminal of the aircraft.
