This study was part of an on-going effort to evaluate plans for increasing air traffic capacity and to evaluate the feasibility of using multiple simultaneous, parallel, Instrument Landing System ILS approaches. The objective of this study was to evaluate the ability of experienced controllers to handle approach traffic during Instrument Meteorological Conditions IMC to a proposed parallel runway airport configuration, using a real-time, interactive, air traffic control ATC simulation. This simulation utilized a current radar system, Airport Surveillance Radar ASR-9, and a current display system, Automated Radar Terminal System ARTS IIIA. The proposed configuration consisted of parallel runways i. e. , 18R, 18C, and 18L , 10, 000 feet ft long, spaced 5000 ft apart with even thresholds. Triple simultaneous parallel ILS approaches were simulated with controllers monitoring traffic on the approach localizers. To challenge the system, blunders were introduced, according to predetermined scenarios, by having some of the simulated aircraft deviate from the localizer by either 10, 20, or 30 degrees. Furthermore, half of the blundering aircraft also simulated a total loss of radio communication NORDO with the controllers.
