Traffic collision avoidance system

Tcas (Traffic colission aviodance system): This system is displayed intergrated in the ND (Navigation Display). This is the case in de Airbus family aircraft. It also can be intergrated in the IVSI (Instantanious Vertical Speed Indicator; wich indicates the vertical speed of the aircraft, if it's descending or climbing). This is the case in Boeing aircraft.

The TCAS displays other aircraft (equipped with TCAS) in the near area of the aircraft (to be selected by the pilot and can vary from 2,5 to about 30 miles range) If another aircraft tends to collide with the other aircraft, a audio and visual warning will apear, indicating the incoming aircaft, and the audio signal indicates the to be followed action by the pilot. Examples can be either climb climb climb or dive dive dive. Ofcource the TCAS in the other aircaft will signal the opposite so a colission can be avioded.
