TCAS in Australia


The carriage of traffic collision avoidance system (TCAS) equipment is not mandatory in Australian aircraft. However, many Australian and foreign registered aircraft operating in Australian controlled airspace are equipped with TCAS because of their compliance with a US requirement when operating in American airspace.
A total of 157 TCAS-related air safety occurrences were reported in Australian airspace during 1993 and 1994. The circumstances of these events, and the views of the pilots and air traffic controllers involved in the occurrences, were examined in detail.

Early versions of TCAS produced nuisance or unnecessary warnings, but later software has almost eliminated these problems. TCAS has had a positive safety benefit in Australia and is considered to be a valuable additional safety net in the Air Traffic Services system.

In June 1995, following a serious breakdown of separation between two passenger jets, BAS1 made a wide-ranging recommendation to the Civil Aviation Authority (CAA), calling for the frtment of airborne collision avoidance systems to all aircraft engaged in regular public transport (RPT) operations. In November 1996, the Civil Aviation Safety Authority (CASA) released a legislative instrument proposal dealing with the introduction of TCAS equipment to certain commercial transport aeroplanes.
