New Techniques for Air Traac Management for Single and Multiple Airports

Air tra c worldwide continued to grow in 1993, despite the medium-term e ects of the recession in many countries. The direct and indirect costs attributable to air tra c congestion are already enormous, and are predicted to rise to US$10 billion in Europe alone. The challenge is to match the demand with the available capacity. The alternatives are to increase capacity, restrict demand or achieve more e cient utilization of the existing infrastructure. Increasing capacity requires enormous capital expenditure, while restricting demand leads to revenue loss. Some relief can be provided through increasing e ciency, the rationale for the development of new air tra c management procedures and accompanying systems. This paper discusses the di culties of improving air tra c management, and new solutions to these problems.
