Abstract
This paper reviews the techniques open to the study of air traffic control systems and, in particular, the feasibility of fast-time simulation methods. The peculiarities of an ATC system and the difficulties of representing it by a logical element are discussed. A description is, nevertheless, given on the progress which has been made in the development of the so-called ‘ Ground ’ model, a fast-time simulation which, although still in its infancy, is expected to evolve very soon into an efficient tool for the study and comparison of various ATC systems and organisations.
