Senator COLLINS —On 19 May I was asked a question by Senator Chapman regarding CAA board approval of a new airspace system. I have a detailed response for Senator Chapman, and I seek leave to incorporate it in Hansard.

  Leave granted.

  The answer read as follows

  The CAA Board approved the implementation of an ICAO based airspace model at its meeting on 31 March 1993.

  This approval follows the most extensive period of industry consultation ever undertaken by the Authority. As a consequence of this consultation, the model as now refined, is supported by the full range of industry users.

  Australia has for over 20 years, been operating jet aircraft flights into uncontrolled aerodromes without separation, in other words, with no Air Traffic Control. Since December 1991, such operations have also been conducted without a directed traffic information service about Visual Flight Rules (VFR) flights, such as those often involving general aviation aircraft.

  Under the airspace model, all aircraft operating at Mandatory Traffic Advisory Frequency (MTAF) locations, such as Yulara, will be required to make mandatory radio broadcasts. This will provide jet airline aircraft operating at these locations with traffic advice about all aircraft operations. By comparison, overseas practice usually limits traffic advisories to Instrument Flight Rules (IFR) flights, rather than IFR and VFR.

  The use of MTAF procedures is subject to additional consultation with the industry through the Authority's Aviation Regulatory Proposal system. The CAA is satisfied that the airspace classifications that will be introduced in November 1993 will achieve the necessary balance to preserve air safety whilst containing costs to the flying public.
