ABSTRACT
A constantly evolving real time computer simulation of air traffic in a terminal area has been developed at the Research Triangle Institute. The model is a flexible simulation of airborne, navaide, ground control, and communications aspects of the terminal area environment which is, with input data changes, adaptable to existing terminal areas and which can be and is being expanded to incorporate advanced concepts of instrumentation and control techniques. This talk describes the basic computer program and input data organization of the model and deals with programming techniques, such as program overlaying, data packing and threaded lists, used to resolve problems created by its requirements of versatility and flexibility, by constraints and advantages of a real time simulation, and by limitations on available core storage. The basic philosophy behind its design was to isolate the various functions performed within the terminal environment such that these functions could be called into use as needed by a particular data set and expansion of the capabilities of the model could be accomplished through unit additions to the program.
