Efforts to prevent collisions


TCAS

Almost all modern large aircraft are fitted with a traffic collision avoidance system (TCAS), which is designed to try to prevent mid-air collisions. The system, based on the signals from aircraft
transponders In telecommunications, a transponder is a device that, upon receiving a signal, emits a different signal in response. The term is a blend of ''transmitter'' and ''responder''. In air navigation or radio frequency identification, a flight trans ...

Civilian/military mid-air collisions in the United States

On some occasions, military aircraft conducting training flights inadvertently collide with civilian aircraft. Before 1958, civilian air traffic controllers guiding civilian flights and military controllers guiding military aircraft were both unaware of the other's aircraft. The 1958 collision between
United Airlines Flight 736 United Air Lines Flight 736 was a scheduled transcontinental passenger service flown daily by United Airlines between Los Angeles and New York City. On April21, 1958, the airliner assigned to the flight, a Douglas DC-7 with 47 on board, was fl ...
