Operators of foreign registered aircraft: implementation of RNP 1 and RNP 2
This guidance information is for operators of foreign registered aircraft on the requirements for Required Navigation Performance (RNP) 1 and 2 Navigation Specifications (Nav Specs).
On this page
Can an operator of a foreign registered aircraft operate into, within and out of Australian Airspace without RNP 1 and RNP 2 Navigation Specifications?
Yes, some foreign operators may not be able to obtain RNP 1 and/or RNP 2 Navigation Specification (Nav Spec) from their National Aviation Authority (NAA) because:
- The aircraft operator does not have RNP 1 and/or RNP 2 Nav Spec on their Operations Specification (Ops Spec) or
- The NAA does not have rules that enable them to issue RNP 1 and/or RNP 2 Nav Spec.
Under the provisions of an Exemption (EX151/20), CASA has approved operators with an acceptable means of compliance (AMC) for equivalent Nav Spec’s. Such operators may operate aircraft on Australian continental RNP 2 routes and RNP 1 procedures with RNAV 1 & RNAV 2 Nav Specs using GNSS, or an acceptable equivalent combination of Nav Specs.
Prior to exercising the privileges of the CASA exemption operators must complete and submit:
- Form 0667 to International_Ops@casa.gov.au, along with a copy of the Ops Spec; and
- Acknowledgment of advising their NAA of operations on Australian RNP 2 Continental routes and/or RNP 1 procedures in accordance with the NAA approved Nav Spec’s or as indicated on the NAA approved Ops Spec.
Aircraft that do not meet the equivalent RNP 1 and RNP 2 Nav Spec requirements on Form 0667 can continue operations into Australian airspace, in accordance with the 'General guidance on the GNSS mandate, decommissioning of NAVAIDs and implementation of RNP 1 and RNP 2' (page 4 clause 15), with the NAA approved Nav Spec’s or as indicated on the NAA approved Ops Spec.
In this case operators of foreign registered aircraft will Flight Plan and navigate in accordance with the approved Nav Specs. Airservices Australia will provide the applicable separation and strategic traffic management based on the aircraft capabilities and crew qualifications indicated in the ATS Flight Plan.
The operator must continue to Flight Plan in accordance with the ICAO flight planning requirements and any special flight planning requirements in ENR Section 1:10 'Flight Planning' of the Australian AIP, annotating in Field 10 and Field 18 of the ATS Flight Plan, details of the applicable equipment and Nav Spec capability of the aircraft, for which the crew are qualified to use.
The operator of an aircraft in accordance with Exemption EX151/20 must ensure that the flight plan for each operation includes the following details in Item18 of the ATS flight plan: RMK/CASA RNP AMC.
For more information refer to the Navigation for communication, navigation systems and air traffic management page.
No, the GNSS equipment mandates that became effective on 4 February 2016 are applicable to Australian registered aircraft only - operators of foreign registered aircraft are not required to comply with the GNSS requirements of CAO 20.18.
