Airport Surface Traffic Control System Requirements Analysis.

摘要

This report documents the results of an Airport Surface Traffic Control (ASTC) requirements analysis. Problems and potential payoffs are explored in the areas of capacity and delay, productivity, safety, and equipment limitations. Alternative approaches to solving ASTC problems are identified and their costs estimated. Benefits are estimated and alternatives compared. The potential for Ground Control saturation during bad cab visibility is shown to exist at Chicago O'Hare today, and at Los Angeles and Atlanta by the mid-1980's. the Tower Automated Ground Surveillance (TAGS) concept, using multiple ATCRBS interrogators to add target identity to the output of the ASDE-3 in a single hybrid display, is recommended for development and deployment at these three airports. Analysis shows that increased traffic forecasts could require two ground controllers at ten airports by the late 1980's. A standard taxiway routing system might eliminate the second ground controller at eight airports, with annual benefits of $500,000. Analysis of accidents occurring on the surface of ATC-towered airports reveals that 87% of accident costs and 76% of fatalities occurred at the top 25 air carrier airports. A study is recommended to identify the causes and hypothesize solutions to this category of accidents. Another potential safety problem is lack of positive runway clearance assurance at airports which operate during bad cab visibility but do not qualify for an ASDE-3.
