A GOMS analysis of the advanced automated cockpit

Abstract

Using models developed to analyze office automation (e.g.[3]), we identified skilIs needed to perform tasks using the flight management computer on advanced commercial aircraft, Our GOMS analysis showed that all tasks carried out on the device can be described in terms of three methods. Novices who received instruction in a part-task computer based training guided by the GOMS analysis were tested in a flight simulator, Their performance was compared with pilots who received an integrated type of training representing three to ten times the amount of time on task and with pilots who had been using this equipment on the line for at least one year ("experts"). Inconsistencies revealed by the analysis were reflected in the performance of novices (experimentally and professionally trained) as well as the experts.
