Abstract:The primary objective of this research is to support the FAA Airborne Data Monitoring Systems Research Program by developing new and improved methods and criteria for processing and presenting commuter airplane flight and ground loads usage data. The scope of activities performed involves defining the service related factors that affect the operational life of commuter aircraft and providing processed data in statistical formats that will enable the FAA to assess existing certification criteria. Equally important, these new data will enable the FAA, the aircraft manufacturers, and the airlines to better understand and control those factors that influence the structural integrity of commuter aircraft. The University of Dayton under contract with the University of Alabama processed digital flight recorder data collected from 903 flights representing approxinately 585 flight hours recorded on 28 typical BE-1900D aircraft during typical operational usage by a single commuter airline. This report presents statistical summaries of aircraft usage data, ground loads data, flight loads data, and systems operational data collected from these aircraft. Statistical data are presented for parameters such as gust and maneuver acceleration, airspeed, altitude, flight duration and distance, engine RPM and torque, time at propeller reversal, derived gust velocity, V-n diagrams, and vertical and longitudinal accelerations during ground operations. this report presents the results from this effort.
