Performance-based navigation: stand-alone navigators
If you are flying in Australia you need to be aware of new PBN approvals and, if required, how to obtain them.
Australia is completing the transition to area navigation using International Civil Aviation Organization (ICAO) standardised performance-based navigation (PBN) standards, which use global navigation satellite systems (GNSS) as the enabling technology.
If you are flying in Australia you need to be aware of the new PBN. You also need to be aware of flight planning requirements and ensure your GNSS equipment is properly configured.
Australia-specific area navigation approvals (GPSRNAV, GPSOCEANIC and AUSEP) ended on 13 July 2014 and have been replaced by PBN approvals. Australia has adopted the following PBN specifications:
- Oceanic – RNP 4 (preferred) • En Route – RNP 2
- Terminal – RNP 1
- Non-precision approach - RNP APCH (currently charted as RNAV (GNSS))
- RNAV 10/RNP 10 is supported.
How to obtain a PBN approval
If the aircraft manufacturer states the aircraft’s PBN capability, this is accepted by CASA. Many new aircraft come with a statement outlining PBN capability in the flight manual or capability document.
Aircraft with stand-alone navigators are generally covered by deeming provisions, meaning the aircraft is deemed to have PBN capabilities. If the aircraft is not used in oceanic areas, deemed approvals for PBN RNP 2, RNP 1 and RNP APCH are likely to be all that are required. If the aircraft is operated in oceanic areas RNP 4 or RPN 10 is also required.
Flight planning-PBN capability
PBN capability, whether deemed or granted by CASA, needs to be reflected in flight plans. Follow these steps to ensure this information is entered correctly.
|1 Remove GPSRNAV, GPSOCEANIC and AUSEP|
2 Add PBN approvals:
Z indicates supplemental information is included in Item 18
3 FPL item 18:
|O2 indicates RNP 1 approval based on GNSS
S1 indicates RNP-APCH approval
NAV/RNP2 indicates PBN RNP 2 approval (there should be a letter-number combination used with PBN. However, this is yet to be defined by ICAO)
A1 indicates PBN RNP 10 approval
L1 indicates PBN RNP 4 approval
