TCAS or the “Traffic Collision Avoidance System” is a system that monitors the local airspace around the aircraft, if it detects another aircraft’s transponder it will automatically exchange data with the other aircrafts, data like GPS position, altitude, speed, direction and more.
Then compares data received with it’s own, and determines the risk to the aircrafts involved, and if there is a risk of a mid air collision it will order the flight crew to take action and even cooperate with the other plane to order specific actions to both air crews.
One will be ordered to decend, the other to climb, and TCAS alerts are treated as a higher priority than even a controller.
TCAS, not “tea cast” (:
