[Avionics Today 01-29-2016] The next three mandates regarding communications, navigation, surveillance and air traffic management for Australia under the Australian Government’s Civil Aviation Safety Authority (CASA) will come into effect on Feb. 4.

As of Feb. 4, 2016, all aircraft that operate under Instrument Flight Rules (IFR) must be equipped with Global Navigation Satellite Systems (GNSS). Any aircraft operating at Brisbane, Sydney, Melbourne or Perth airports must have an Automatic Dependent Surveillance-Broadcast (ADS-B) capable Mode S transponder. Last, all aircraft operating under IFR in class A, B, C or E airspace within the quadrant 500 nautical miles north through east of Perth airport must be equipped with approved ADS-B equipment.

The requirement for aircraft to be equipped with an ADS-B capable Mode S transponder when operating at Brisbane, Sydney, Melbourne or Perth aerodromes relates to aircraft operating on the surface of these airports. Airservices Australia has implemented Advanced Surface Movement Guidance and Control Systems (A-SMGCS) at these aerodromes that require aircraft to be equipped with Mode S transponders.
