碩士 === 國立成功大學 === 民航研究所 === 98 === After 911, the small aircraft transportation system (SATS) was launched to increase air transport capacity and reduce major airport traffic loads. Flight activities of small general aviation (GA) aircraft as well as sport ultra light aircraft (ULA) have become a serious concern to low altitude flights below 5,000 feet. Consequently, viable solution of collision avoidance for small aircrafts has an urgent demand by reconstructing the similar confliction avoidance logic for use. This thesis involves a survey of TCAS for small aircrafts in low altitude. The proposed method which had discourse a lot of technologies, comprises of detection and resolution for collision avoidance. On the flight characteristics, some other relative concepts such as visual flight rule and the flight priority are combined into the logic chart. Based on ADS-B concept under VFR, TCAS operation can be built on the ground surveillance computer as well as on the airborne electronic flight instrument system (EFIS). Aircraft conflict will be detected from the ADS information. This thesis is focused on the study of conflict detection and resolution by jointly considering ULA characteristic, especially the flight path diversity. Several feasible scenarios from real flight data are tested in simulations to look into the TCAS performance on the ground computer and the airborne EFIS. The results had confirmed the feasible and reliable development of TCAS for small aircrafts in low altitude flights.
