A new generation of traffic alert and collision-avoidance systems based on the Global Positioning System (GPS) and Automatic Dependent Surveillance Broadcast (ADS-B) is studied in this paper. Two horizontal escape maneuvers are proposed: One is to change speed but not flying direction, and the other is to change flying direction but not speed. The algorithms for conflict detection and collision avoidance are also presented. The relationships between turn angle, horizontal miss distance (HMD), and reserving time, as well as the relationships between speed, HMD, and reserving time, are calculated and analyzed. To effectively avoid collisions by horizontal escape maneuvers, the research results indicate that the speed of the host aircraft required to increase or decrease must be bounded within a speed range, and the angle of the host aircraft required to turn right or left must also be bounded within an angle range.
