Abstract

Abstract Various aircraft parameters are sensed by function sensors, the outputs of these sensors being fed to a signal conditioner and evaluator where the signals are processed and the magnitudes of these various parameters evaluated. When the magnitude of any of these parameters is above or below certain predetermined limits, an output signal is fed to a transmitter which transmits a voice message indicating the out-of-limits condition. The occurrence of out-of-limit conditions for any of these parameters is also digitally encoded and recorded for future reference. Certain outputs of the signal evaluator and conditioner indicative of selected aircraft flight and operating conditions are continually fed to a digital data encoder where they are placed in suitable condition for recording in digital form and from where they are fed to a continually recycling recorder for recordation.
