1. TCAS SSGT Hromek

2. TCAS = Traffic Collision Avoidance System

3. TCAS What is TCAS? How does it work? Procedures Limitations

4. What is TCAS? Aircraft collision avoidance on-board system Checks distances between aircraft Informs pilot about other planes and advises the best way how to avoid the incident

5. How does it work? Based on SSR principle Components – Computer – Antennas – Cockpit presentation

6. How does it work?

8. Procedures In case of conflict between an ATC instruction and TCAS advise must pilot obey TCAS – Resolution Advisory (RA)

9. Limitations Expensive (about $50 000) ATC is not always informed about the advise given by TCAS to the pilot (depends on SSR) Demand advise could be outside the normal/safe envelope of an aircraft Supporting only vertical maneuvers Mandatory only in planes carrying 19 passengers and more or aircraft with max. T/O mass of over 5 700 kg
