The potential for safely reducing the runway separation standard for simultaneous instrument landing system (ILS) approaches is demonstrated; the standard is based on the current surveillance system. A general autoregression model that generates realistic and stabilized final approach flight tracks is developed. The model is then used in a simulation of simultaneous ILS approaches during which the aircraft deviate normally about the ILS (Simulation 1), to study the probabilities of violating the no-transgression zone and causing false alarms (the probability that radar displays the aircraft in the no-transgression zone when it actually is in the normal operating zone). Simulation 2, which is simular to Simulation 1, considers a worst-case scenario of simultaneous ILS approaches during which one aircraft blunders and determines the probability of collision. Simulation 1 and 2 results indicate that the minimum runway separation that maintains the probabilities of false alarm and collision for the current runway separation and surveillance system is 3,700 ft, when used with radar having an update interval of 2.4 sec and an accuracy of 1 milliradian.
