N2 - This work presents the design, implementation, qualification and flight data evaluation of an in-flight Health and Usage Monitoring System of the Israeli Air Force "Heron" UAV. The system is based on Fiber Bragg Grating (FBG) sensors embedded into the wing and tail booms. Reliable flight data were recorded by the sensors during a dedicated flight test, covering the full UAV flight envelope, and continue to be recorded during the normal operation of the aircraft. The on-board collected data are processed off-line on the ground and analyzed both in the frequency and time domains so that booms load spectra and vibration signatures can be identified and tracked. Based on the data obtained, it is now possible to track this UAV actual load spectrum and its impact on the UAV structural integrity.
