Abstract

Current air traffic control facilities in terminals that operate with automated radar terminal system III equipment require controllers to (a) monitor displays of radar-derived situation data; (b) make decisions; (c) voice communicate with pilots to transmit clearances, maneuver instructions, proximate traffic, and navigational advisories; (d) communicate with other controllers to coordinate their control actions; and (e) maintain computerized and hard-copy data records describing aircraft flights. The time spent performing these activities depends on local traffic routing characteristics and related procedural control requirements, including visual versus instrument airport approach operations. The work-load models differentiate the work activity characteristics of various airspace sectors and quantify traffic capacity (aircraft per hour) according to the number of persons assigned to a sector control team. The modeling approach demonstrated uses field data collected at the Oakland Bay Terminal radar approach control facility. Traffic capacities are calculated for various sector operational alternatives that represent current and proposed automated control systems.
