TCAS Awareness kit

Clear of Conflict. Raising Awareness of the Airborne Collision Avoidance System (ACAS) User Interface is an aid to, and not a substitute for proper TCAS training. This aid was developed by National Air Traffic Services (NATS) in association with FlightSafety International and EUROCONTROL. More information about TCAS can be found here.

Pilots must never manoeuvre in the opposite sense to an RA

Pilots must communicate RA's to controllers as soon as possible

Controllers must not interfere with pilot's reactions to RAs

Vertical speed must be reduced in response to the 'adjust vertical speed' RAs

TCAS II displays should not be used for Self-Separation

Aircrew should consider reducing vertical speed when approaching their cleared flight level

In a TCAS environment aircraft must operate their Altitude Reporting Transponder

TCAS II must be operated in RA mode to provide full safety benefits

For maximum safety benefits, Pilots should follow RAs promptly and accurately
