types of traffic systems aviation
System (BCAS), a transponder-based. airborne system. In 1978, a second mid-air collision. occurred near San Diego between an air carrier and a. general-aviation aircraft, leading to the expansion of. the BCAS effort; in 1981, the name was changed to the. Traffic Alert and Collision Avoidance System (TCAS).
A UAS traffic management (UTM) system for low-altitude airspace may be needed, perhaps leveraging concepts from the system of roads, lanes, stop signs, rules and lights that govern vehicles on the ground today, whether the vehicles are driven by humans or are automated.
Aircraft communications are being expanded; in fact, in recent years a new abbreviation has surfaced. CNS ATM stands for âCommunication, Navigation, and Surveillance and Air Traffic Managementâ which was created to support modernization of the dated and overload prone Air Traffic Control system. Aircraft that are intended to transport passengers are equipped with radios that enable analog voice communications. This is currently and will be for the foreseeable future the primary means for pilots to communicate withdifferent entities of the Air Traffic Control (ATC) system.
