Flight Crew Task Reconstruction for Flight Data Analysis Program

Abstract

The Japan Aerospace Exploration Agency (JAXA) has started development of a proactive flight crew operations safety analysis tool designed to be used within an air carrier's FDA (Flight Data Analysis) program. The tool reconstructs flight crew activities, both tasks which are directly detectable from an FDA dataset by changes of system parameters, and tasks which cannot be observed directly from the dataset by using an embedded rule-based human behavioral model. The model generates an estimated sequence of flight crew procedural activities as well as a workload time history. These outputs are used to assess potential problems in daily flight crew operations, such as deviations from Standard Operating Procedures (SOPs) or high workload situations, for the prevention of exceedances and incidents. As an initial step of the development, a prototype flight crew task reconstruction routine was constructed, and a numerical simulation experiment demonstrated the tool's potential capabilities.
