Human factor modelling for fast-time simulations in aviation

Purpose - The paper aims to present the findings of a research project "Human Factors in 'Fast-Time' Simulation" which was supported by Central European Air Traffic Services - CEATS Research, Development and Simulation Centre (CRDS) EUROCONTROL.Design methodology approach - With the aim of improving fast-time simulations by developing new models related to the air traffic controller's decisions, a simple traffic situation was chosen. It is focused on a pair of aircraft where one aircraft is cruising while the second is requesting clearance for climbing to the same flight level and proceeding flight "in-trail" whereby flight level is not occupied with other traffic.Findings - In order to determine parameters important to the controllers while making a decision, pilot inquiry was realized in the EUROCONTROL CRDS. The results obtained were used for determining the content and form of the final interview. The model based on the final interview results is designed on the "black box" principle - for certain inputs, output is a two-dimensional decision: YES NO give the clearance to the aircraft to climb. The model coincides to a high degree with the real system, confirming its credibility.Practical implications - The established model could improve fast-time simulations. By defining all relevant traffic situations, developing rule bases for every day traffic situations will be possible. Those rule bases could cover mayor situations which controllers are often confronted with. Integration of the model into fast-time simulators could improve the credibility of simulated air traffic to the real traffic system.Originality value - The paper deals with the various aspects of human factor modelling in aviation.
