General aviation has been promoted by Small Aircraft Transportation System (SATS) to broaden air transportation services. Under such development, the National Airspace System (NAS) will change dramatically in congested airspace. In this decade, the unmanned aerial vehicle (UAV) has rapidly growing into civilian applications. Low altitude airspace becomes more crowded. As a result, collision avoidance...
The development of unmanned aerial aircrafts (UAVs) has made great progress recently for its broad uses in disaster rescue missions or civilian applications. UAV may be operating in joint missions with manned aircraft, mostly by helicopter. Traffic alert and collision avoidance system (TCAS) plays an important role to manned aircraft. This paper uses the concept of automatic dependent surveillance-broadcast...
High density small aircrafts increasingly threaten flight safety to low altitude flights. Unlike the general air transport aircrafts, small aircrafts do not install with active detection for collision avoidance. Through available surveillance communication, small aircraft can be monitored in real time while appropriate separation can be applied. A Traffic Alert and Collision Avoidance System (TCAS)...
Radio Data System (RDS) is a mature technique which has been developed over the past 20 years. Due to the common use of FM radio, the traits of low estate requirement and the convenience in broadcasting, RDS is suitable for use in wireless transmission of large-range and low-load data. This proposes the application of RDS in the Traffic Collision Avoidance System (TCAS) for low altitude flights. The...
