Statistical Loads Data for Boeing 737-400 Aircraft in Commercial Operations

摘要

The primary objective of this research is to support the FAA Airborne DataMonitoring 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 which 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. Presented are analyses and statstical summaries of data collected from 11,721 flights representing 19,105 flight hours of 17 typical B-737-400 aircraft during operational usage recorded by a single airline. The data include statistical information on accelerations, speeds, altitudes, flight duration and distance, gross weights, speed brake/spoiler cycles, thrust reverser usage, and gust velocities encountered.
