PRELIMINARY TWO-DIMENSIONAL AREA NAVIGATION TERMINAL SIMULATION

Abstract : The simulation study analyzed selected controller workload and system performance measures for two route configurations representing two time frames and various percentage mixes of area navigation (RNAV) and non-RNAV operations, referred to in this report as participation levels. Results indicated that controllers could use RNAV maneuvers in the control of traffic in lieu of radar vector techniques and that controller workload decreased as the RNAV participation level increased. Controller acceptance of RNAV principles and techniques in terminal ATC increased as familiarity and experience with the various RNAV functions were gained. Subjective results pointed out that in order that RNAV be an effective tool within the terminal air traffic system, adequate training and a thorough familiarization with RNAV procedures, capabilities, and limitations would be a requirement for both controllers and pilots.
