Authorisation for aircraft operating without ADS-B transmitting equipment
CASA has granted a temporary authorisation (instrument CASA 05/16) under the Civil Aviation Orders (CAO) enabling air traffic control to manage on an as-needs basis non-ADS-B equipped instrument flight rules (IFR) aircraft operating in Australia or flying into or out of Australian territory.
The authorisation, which expires at the end of 1 February 2017, will enable air traffic controllers to better manage daily workloads, aircraft separation issues and to facilitate weather avoidance when required.
The authorisation applies to non-ADS-B equipped aircraft but which are equipped with an SSR transponder in areas where there is SSR surveillance coverage or in oceanic control areas. It does not apply to areas where there is ADS-B coverage only. Operators of non-ADS-B equipped aircraft should not automatically expect to be granted clearance by ATC as a result of the authorisation and all existing ADS-B mandates continue to remain in effect. Operators of non-ADS-B equipped aircraft are also advised to carry enough fuel to fly below flight level (FL) 290 following the expiry on 11 December 2015 of a general exemption that allowed non-ADS-B aircraft to operate at or above FL290.
Under the temporary authorisation for aircraft operators, all existing mandated limitations for non-ADS-B equipped aircraft continue to apply and operators of non-ADS-B equipped aircraft will need to flight plan accordingly. If operators plan to conduct frequent flights using non-ADS-B equipped IFR aircraft, they should apply separately to CASA for consideration of an individual exemption or CAO authorisation which would only be available until February 2017.
All applications for individual exemptions or authorisations must be accompanied by a safety case. Each application will be assessed individually, on its own merits, in order of receipt by CASA and any exemption or authorisation issued would only be valid for the period of time an owner or operator needs until their aircraft is properly equipped.
CASA has been implementing new rules and equipment mandates since February 2009 to align Australian operations with global standards set by the International Civil Aviation Organization for communications, navigation, surveillance and air traffic management.
The final mandate comes into effect on 2 February 2017, when all aircraft operating under IFR must be equipped with approved ADS-B equipment.
