Improving Cockpits through Flight Crew Workload Measurement,
Abstract
This project measures objectively the flight crew workload with sufficient sensitivity to differentiate between alternative crew station layouts, controls, and displays. The computerized technique concentrates on design factors under the control of crew station designers and provides for quick and low-cost iteration of alternatives. The program provides workload as related to specific equipments and systems, permitting special attention to be given to high workload items during the early development of concepts and hardware before simulation is available. The technique and program is also applicable to integrated displays, including those where programming to meet information requirements is an element. The analysis is based on a typical flight mission scenario constructed to explore the expected operational envelope and to exercise a major portion of the aircraft displays, controls, and systems in a sequence and time frame typical of the more demanding operations planned. The primary measure is the ratio of the required performance time to the time available within the time constraints regulated by a specific flight, supplemented by hand movement action and distance data. The operating procedures are detailed for computer handling in a way that relates a single workload element to a single piece of equipment, with the equipment coded by its location and ATA number. The times for completing specific acts in the cockpit are developed by detailed analysis of each task and its associated equipment using standard action and reading times. The hand movement and distance data are developed using a full-size design aid.
