If a collision course is detected and the aircraft is suitably equipped, a TCAS alert will be sounded.

For a RA Alert, TCAS RA Direction will determine if the initial alert was Up = +1, Down = -1 or Preventive = 0. The length of time for which the alert was raised will be recorded as TCAS RA Warning Duration.

Traffic collision avoidance systems are transponder based air-to-air traffic monitoring and alerting systems. There are two classes of TCAS. TCAS I was developed to accommodate the general aviation community and regional airlines.

On 24 February 2004, the ATC who was on duty at the time, was stabbed to death by a man who had lost his wife and two children in the accident. It is obviously imperative that TCAS alert the flight crew early enough that evasive action can be taken. But it is also important that TCAS not alert unnecessarily. Collision avoidance alerts represent high-stress, time-critical interruptions to normal flight operations.

TCAS (Traffic alert & Collision Avoidance System/TCAS) This system warns pilots of the presence of other aircraft in the proximity which may pose a threat, and gives instructions to avoid mid-air collision.

FlightGear (version 2.3.0 and above) provides an instrument emulating the TCAS II Version 7 standard. called TCAS Alert Prevention or TCAP.

Trafikkollisionsvarningssystem, (engelska: Traffic collision avoidance system eller Traffic alert and collision avoidance system både förkortat TCAS, och uttalas tee-kas) är ett flygburet kollisionsvarningssystem (ACAS) utformad för att minska förekomsten av kollisioner i luften mellan flygplan. TCAS II increases the threat sensitivity in 7 steps: From 20 seconds at 1000 ft to 50 seconds above 20000 ft for traffic alerts, and from 15 to 35 seconds for resolution advisories. Features TCAS display TCAS Alert, TCAS Caution definition: A TCAS “Caution” is issued whenever an airplane is at ±1600 ft and/or at 7 NM from your position.
