What should a pilot do on receiving a TA?
In accordance with PANS-OPS (ICAO Doc.8168), on receipt of a Traffic Advisory (TA) the pilot must use all available information to prepare for appropriate action if an RA occurs. Pilots must not manoeuvre their aircraft in response to TAs only.TAs are intended to alert pilots to the possibility of a resolution advisory (RA), to enhance situational awareness, and to assist in visual acquisition of conflicting traffic. However, visually acquired traffic may not be the same traffic causing a TA. Visual perception of an encounter may be misleading, particularly at night. It must be noted that not all TAs are followed by an RA.
