| 摘要： | This report presents revised criteria for VFR Airport Traffic Control Tower establishment and discontinuance based on an economic analysis of tower benefits and costs. In compliance with P.L. 100-223, the previous tower establishment and discontinuance criteria have been revised to eliminate distinction according to aircraft size. In addition, benefit estimation procedures have been updated to reflect accident rate differentials between towered and nontowered airports experienced during the period 1983 to 1986. Cost reflect those experienced during 1988 by the FAA for tower construction, equipment, and operation. Site-specific activity forecasts are used to estimate tower benefits from prevented collisions between aircraft, other prevented accidents, and reduced flying time. The present value of these safety and efficiency benefits are compared with the present value of tower costs over a fifteen-year time frame. Establishment costs include annual costs for staffing, maintenance, equipment, supplies and leased services and investment costs for facilities, equipment, and operational start up. A location becomes a candidate for tower establishment when the benefits which derive from operating the tower exceed the costs; a tower becomes a candidate for discontinuance, when the costs of continued operation exceed the benefits. Application of these criteria enable the Federal Aviation Administration to prioritize investments among alternative sites according to the greatest return in benefits for dollar investments. |
