The Federal Aviation Administration (FAA), supported by the University of Dayton, conducts research on the structural integrity requirements for the U.S. commercial transport airplane fleet. 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 large commercial transport airplane flight and ground loads usage data. The scope of activities performed involved (1) defining the service-related factors that affect the operational life of commercial aircraft; (2) designing an efficient software system to reduce, store, and process large quantities of optical quick-access recorder data; and (3) providing processed data in formats that will enable the FAA to reassess existing certification criteria. Equally important, these new data will also enable the FAA, the aircraft manufacturers, and the airlines to better understand and control those factors that influence the structural integrity of commercial transport aircraft. Presented herein are analyses and statistical summaries of the data collected from 11,066 flights representing 95,883 flight hours from Boeing 747-400 aircraft during operational usage recorded by a single airline. The flight loads data include statistical information on accelerations, speeds, altitudes, flight duration and distance, gross weights, speed brake cycles, thrust reverser usage, and gust velocities encountered.
