Statistical Loads Data for the Boeing 777-200ER Aircraft in Commercial Operations Final rept

摘要

The University of Dayton Research Institute supports the Federal Aviation Administration (FAA) by conducting research on the structural integrity requirements for the U.S. commercial transport airplane fleet. The primary objective of this task was to support the FAA's Airborne Data Monitoring Systems Research 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 included: (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) reducing, analyzing, and providing processed data in statistical formats for the FAA to reassess existing certification criteria. Equally important, these new data also will 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 Boeing 777-200ER aircraft operational usage data collected from 10,047 flights, representing 67,000 flight hours, recorded by a single international operator. Data are presented that will provide the user with statistical information on aircraft usage, ground and flight loads occurrences, and system operational usage based on actual B-777-200ER operational usage. The aircraft usage data include statistics on aircraft weights, flight distances, altitudes, speeds, and flight attitudes.
