Australia: The mandate is designed to align Australian operations with global standards set by the International Civil Aviation Organization (ICAO) for Communications, Navigation, Surveillance and Air Traffic Management (CNS/ATM).
The changes include the requirement that all aircraft operating under instrument flight rules (IFR) must now be equipped with GNSS avionics meeting TSO C129, which enables compliance with Required Navigation Performance (RNP) 1 terminal area and RNP 2 continental en route operations that begin May 26.
GNSS is the enabling technology for both performance-based navigation (PBN) and automatic dependent surveillance-broadcast (ADS-B) in Australia and will affect all IFR aircraft. To help foreign-registered aircraft operators in meeting the new requirements, transition arrangements are available for a two-year period. Operators who need the extension must complete an online form before their first flight in Australia on or after May 26.
