The Operation of Regular Public Transport (RPT) Aircraft in Mandatory Traffic Advisory Frequency (MTAF') Airspace


MTAF procedures were introduced in Australia with the AMATS changes of 12 December 1991. The MTAF procedure applies at specified aerodromes. It depends on pilots making mandatory radio calls, hearing calls from other aircraft, assessing this traffic information for potential conflict, and responding appropriately with radio communication and avoiding action if necessary.

The MTAF procedure is designed to alert aircraft to all other air traffic in a designated area surrounding a particular aerodrome. The procedure mandates certain radio broadcasts and responses in these areas, and the pilots are then responsible for arranging their own separation.

In March 1993 BASI was informed that airline pilots had considerable concerns over the safety of RPT operations in MTAF areas. Reports stated that "Since the inception of MTAFs, [pilots] are experiencing conflict situations with unannounced, unalerted traffic, on a daily basis. This is resulting in numerous instances of immediate evasive action having to be initiated by aircraft operated within MTAFs".
