The working principle of TCAS and the working principle of TCAS
Aircraft collision avoidance system, the American aviation system called air traffic warning and collision avoidance system (TCAS:Traffic Alert and Collision Avoidance)
System) European Aeronautic system is called Airborne Collision Avoidance System (ACAS:Airborne Collision Avoidance)
(System)) the actual meaning and function of the two are consistent. The collision avoidance system can display the situation around the aircraft, and provide voice alarm when necessary, while helping the driver to avoid danger by appropriate maneuver, which can help to avoid catastrophic accidents.
Let's take TCAS as an example.
TCAS's history can be traced back to 1955, when the Bendix Aviation Electronics (now part of Honey pany) Dr. published "collisions" article. It includes puter algorithm to determine the approaching speed between aircraft, which is the basis of studying all anti-collision systems. In 1960s and 70s, pany developed several prototype machines for the US Army and the Federal Aviation Administration (FAA), and in the late 80s, the first identification of TCAS by FAA was made.
Appearance of TCAS equipment
Principle:
In the principle of determining the number, course and height of the aircraft by the two radar transponder, the inquiry device is installed on the aircraft
The aircraft can display the distance between each other, so that the driver knows the distance between the aircraft flying in a certain range, take timely measures to avoid collision. Like the two radar, the TCAS system needs to be equipped with transponders on the aircraft.
On the type of two radar reference to air traffic control radar
Composition and function:
TCAS is posed of interrogator, transponder, transceiver puter. The monitoring range is 30 nautical miles ahead, 3000 meters above and below, and a smaller distance between the side and rear. In order to reduce radi
