  • Patent number: 3979579
    Abstract: In an aircraft, a system for recording aircraft fatigue cycles senses engine starting, engine shutdown, landing gear status, engine reversal and throttle setting and derives therefrom unit and fractional cycles. The system includes a first memory responsive to the aforementioned sensors for producing an indication of when the aircraft is in flight and a second memory for producing an indication of when the landing gear are dropped in flight. These memory indications are fed to gates which index the units counter when a takeoff, landing and engine shutdown cycle is completed and which index the fractions counter when a retakeoff without engine shutdown is accomplished. Other gates cause the units counter to be indexed when the engine is restarted in flight. In a multi-engine aircraft, sensors and counters are provided individually for each engine.
