Abstract

An onboard portion of the system is located on an aircraft for monitoring a plurality of flight parameters and detecting a predetermined exceedence indicative of a potential problem. With regard to flight data, predetermined exceedences could include abnormal attitude, control surface actuator failure, low hydraulic fluid pressure, low fuel, near stall speed, excessive engine RPM, engine failure, cabin pressure loss, and so forth. With regard to voice data, predetermined exceedences could include excessive decibel levels, excessive static, overly long periods of silence, and other audible conditions indicative of cockpit intrusion. Flight data representative of the flight parameters is transmitted via RF signals upon the detection of the predetermined exceedence. A remote portion of the system receives the transmitted RF signals carrying the flight data and records the flight data for analysis.
