Abstract : The generic sector evaluated in this study was based on a four-corner post operation typically used in many terminal areas in tne United States. Arrival aircraft originated from one of four arrival fixes just outside the sector boundaries. These arrival routes can be thought of as spokes of a wheel with the main airport site as the hub. In addition to the main airport, there were three satellite airports that were under radar control. Departure aircraft from the main and satellite airports were sent directly to one of four departure fixes located outside the sector boundaries. Eleven air traffic controllers from the Atlantic City TRACON participated in the study. The experiment was conducted at the Federal Aviation Administration Technical Center's Human Factors laboratory at the Atlantic City International Airport, New Jersey. The experimental apparatus consisted of a high fidelity air traffic control simulator with voice communication equipment to allow controllers to issue commands to remote simulation pilots. The results showed significantly lower Air Traffic Workload Input Technique (ATWIT) ratings by the last generic run compared to the first generic run on the first-day training runs. Time under control and the distance flown by the aircraft significantly decreased by the last training run. Controller ratings of workload and stress were also significantly lower by the last generic run. in addition, post-scenario questionnaire ratings for ability to plan, exchange information, and prioritize were significantly higher by the last run. Correlations between scores on the generic sector and the Atlantic City sector we're significant for the over-the-shoulder ratings, ATWIT ratings, and post-scenario questionnaire ratings. Final questionnaire comments indicated that the participants thought the generic sector was representative of a typical terminal environment.
