An Evaluation of Ground Collision Avoidance System Algorithm

Abstract

Controlled flight into terrain (CFIT) accidents, which constitute the second largest category of tactical Air FOrce Class A mishaps, could be greatly reduced by installing forward-looking Terrain-Following Radar (TFR) Systems. In an effort to design a less costly solution to this problem, a software-oriented generic Ground Collision Avoidance System (GCAS) with application to more complex tactical missions was developed. A simulation study of the system evaluated the adequacy of the algorithm in a variety of tactical scenarios. Results indicate GCAS is a variable system for partial solution of CFIT. Although some modifications to the system are necessary prior to implementation, the concept of terrain estimation may give GCAS a capability unmatched by any similar systems. (fr)
