Does TCAS II display all aircraft traffic?

The TCAS II is a system that: Monitors the airspace around the aircraft and communicates with all traffic equipped with a corresponding active transponder.

Where is TCAS 7.1 required?

Currently, TCAS II version 7.1 is mandated in European airspace (other TCAS II version fall outside the mandate).

How does TCAS determine the direction of a threat?

Once an aircraft is detected by TCAS surveillance and determined to be a potential threat, TCAS presents it to the pilot as a Traffic Advisory (TA). If the threat is imminent, then TCAS proposes a vertical avoidance maneuver to the pilot. This is a Resolution Advisory (RA).

Where is TCAS displayed?

The TCAS interface with the pilots is provided by two displays: the traffic display and the RA display.

How does TCAS work?

Working independently from air traffic control, TCAS uses nearby aircraft’s transponder signals to alert pilots to the danger of mid-air collisions. It does so by constructing a three-dimensional map of the airspace through which the aircraft is traveling.

What are the TCAS?

Tricyclic antidepressants (TCAs) are a class of antidepressant medications that share a similar chemical structure and biological effects. Tricyclic antidepressants increase levels of norepinephrine and serotonin, two neurotransmitters, and block the action of acetylcholine, another neurotransmitter.

Is TCAS 7.1 required?

The European Aviation Safety Agency (EASA) requires ACAS II (effectively TCAS II, version 7.1) for all fixed wing turbine powered aircraft that have a maximum takeoff weight of greater than 5,700 kg (12,566 lbs) or have more than 19 passenger seats.

How do I display TCAs information on the navigation display?

TCAS information can be displayed on the navigation display via a switch located on the transponder (on pedestal panel for A320). B737 Navigation Display in ARC mode with terrain radar activated. Radar terrain information can be displayed on the navigation display via a switch located next to the ND.

Are there any traffic indications or TCAS warnings available?

No traffic indications or TCAS warnings are available. TA – This will display “TA ONLY” on the ND’s. All RAs are converted to TAs. Selection of “TA ONLY” will be made, for example, in the case of engine failure when called for by the EICAS/ECAM or if reffered to in a QRH (Quick Reference Handbook) procedure.

What is the diamond on the TCAs display?

Once an aircraft comes into the TCAS airspace of another aircraft, there is a little diamond which pops up on the navigation display, showing the position and the vertical separation of the aircraft. If the other aircraft is within six nautical miles, this diamond becomes completely white.

What is TCAS (Traffic Collision and avoidance system)?

TCAS (Traffic Collision and Avoidance System) is a surveillance system on modern aircraft that uses radio signals to detect and display other nearby aircraft, calculate possible threats and display avoidance guidance to pilots. What Happens When Pilots Receive a TA or RA?
