COMPUTER/SIMULATION STUDY OF AIR-DERIVED SEPARATION ASSURANCE SYSTEMS IN MULTIPLE AIRCRAFT ENVIRONMENT.
Abstract
This report describes (1) analytical studies of three types of air-derived separation assurance (ADSA) techniques, (2) specifications of simulated aircraft environments to be recorded by the National Aviation Facilities Experimental Center, and (3) a computer program which simulates the performance of ADSA techniques under lifelike conditions. The results of the analytical studies are: Measurement errors in the synchronized airborne oscillator (SAO) range-altitude (R-A) system caused less degradation of performance than those of the groundbounce R-A and the interrogator-transponder relative position-velocity (RP-V) systems. Medium quality crystal oscillators can be used in the SAO. Rectilinear accelerations occur for such a short period of time that they cause no serious detrimental effects. The tau criterion can offer complete protection in unaccelerated flight. In turning flight, the normal velocity criterion of the RP-V system is completely unsatisfactory and should be eliminated during turning maneuvers. Of the three systems, the SAO resulted in less critical situations in turns, but still did not offer adequate protection. (Author)
