An anatomy of TROTSKY [ATC simulator program]

TROTSKY is a demonstrator. It demonstrates a radically revised ATC interface for en-route air traffic management. This paper describes the physical realization of TROTSKY. It firstly describes the underlying principles, from which the interface was derived, and secondly describes an evaluation, using TROTSKY, of the speed and accuracy with which this interface can be employed. TROTSKY was written in the DOS-based language QuickBASIC, largely because that language was cheap, available and known to the author. (QuickBASIC is now obsolete. The program is being converted to Visual BASIC, which is slower and uses more time, space and money, but is generally available).
