One year to go for mandatory ADS-B fitment

18 Dec 2012

Business jet operators and airlines are being urged to get fitted with Automatic Dependent Surveillance Broadcast (ADS-B) technology, with now less than a year until the deadline for mandatory fitment.

Due to come into affect on 12 December 2013, the mandate, introduced by the Civil Aviation Safety Authority in 2009, requires domestic and foreign operators of aircraft flying at and above FL290 (29,000 feet) to have ADS-B equipment installed and operating correctly.

Australia’s air traffic control surveillance future is tied to ADS-B – a satellite based air navigation system that enables aircraft to be accurately tracked by air traffic controllers, and other pilots, without the need for conventional radar.

Given the timeframe associated with equipment installation, Airservices continues to encourage all operators, particularly business jet aircraft, to install ADS-B in advance of the mandate. Most airlines are very well advanced in their fitment programs.

Airservices is now seeing over 80 per cent of flights at or above FL290 by Australian registered aircraft, flying in the Australian flight information region, getting the ADS-B service. This is in comparison to eight per cent of Australian registered business jet aircraft.

Benefits of ADS-B equippage include reduced separation standards for aircraft flying outside of conventional radar coverage, which translates into increased safety, reduced use of stepped climbs and descents and more clearances granted to fly requested routes or levels.

Non-ABS-B equipped aircraft will be restricted to operate below FL290, resulting in less operational flexibility and the potential for delays due to the procedural separation standards that will be applied outside radar airspace.
