摘要

Much air traffic between southeast Asia and Europe transits the Kabul FlightrnInformation Region (FIR). Because this airspace lacks surveillance, air trafficrncontrollers must resort to procedural control, spacing aircraft far apart. Controllersrncurrently space aircraft 50 nautical miles (nmi) in trail, which exceeds that required byrnneighboring Pakistan, Turkmenistan, and Uzbekistan. Flights spaced closer than 50rnnmi entering Afghanistan airspace must either be slowed down or assigned lessrnefficient altitudes. This imposes costs and delays on operators.rnThe Afghanistan Civil Aviation Authority (CAA) is considering implementation of arnmultilateration system to provide surveillance of their high-altitude airspace. Thisrnwould allow controllers to use radar-like separation procedures, reducing in-trailrnseparations to at most 30 nmi. We conducted an analysis to determine if the benefitsrnof this investment would justify the cost. Flight trajectory data was not available, sornwe used flight count statistics, including distributions by route and time of day, alongrnwith published air carrier schedules and aircraft performance data, to randomly assignrnflights to routes and altitudes. A simple queuing model was then used to spacernaircraft on each airway and altitude. To analyze future years traffic was randomlyrnincreased based on the historical growth rate in the FIR. Finally, we valued delaysrnusing standard aircraft direct operating costs for each aircraft type.
