To monitor the interaction between aircraft motion and pilot control inputs during such unusual happenings as upsets caused by turbulence and collision-avoidance type of maneuvers, Unusual Event Recording Systems UERS were installed in three jet transports -- a Boeing 707, 727, and 737 - operated by two major airlines in scheduled passenger-carrying flights. Each UERS consisted primarily of a DARS 24-channel magnetic tape recorder, a signal conditioner, and a set of sensorstransducers. As the recording period one year for each aircraft neared completion without any unusual event having been experienced, the data objectives were expanded to produce several types of statistical data on normal airline operation. The resultant 2088 hours of usable data demonstrated the adequacy of the UERS for extended monitoring of commercial aircraft flight parameters and revealed the potential of such data for providing statistical information. In addition to the usable operational data, data from 163 approaches recorded during 727 training flights were processed and presented. Author
