The Australian CAA have said they will now allow foreign operators to use RNAV1/2 in lieu of RNP 1/2.

Over the past few years, Australia has been moving away from ground-based navigation to PBN/GNSS as the primary means of navigation across the country.

Australian operators have all had to be RNP1/2 compliant since May 2016, when they rolled-out RNP2 for en-route and RNP1 for terminal operations.

It’s not yet mandatory for foreign operators to be RNP1/2 compliant – but if you want to benefit from these routes and procedures (and can’t get RNP1/RNP2 approvals from your country of registry), you can notify CASA of your intent to use RNAV1/RNAV2 instead – and they will accept those as equivalent to RNP1/RNP2.

To do that, make sure you fulfil all the criteria in their “Acceptable Means of Compliance” (as contained in CASA EX158/17), fill out Form 0667 and send it to CASA by email, along with a copy of your Ops Spec. Their email address is:

The AMC applies to both commercial and private flights. However, as it’s not a mandatory requirement for foreign aircraft, if you’re operating a private flight you might not want to bother with it; if you can’t meet the equivalent of the RNP1/2 nav spec requirements, you can still operate in Australian airspace – all that will happen is that ATC just might not provide you with the absolute best routes and levels. But even that won’t happen any time soon – at the moment there are still no RNP2 routes in Australia yet, although we will start seeing these being introduced between now and 2020.

Flight Planning:

  • If you do have RNP2 – put GRZ in Field 10a and NAV/RNP2 in Field 18.
  • If you don’t, then you must operate according to Australia’s “Acceptable Means of Compliance” and put RMK/CASA RNP AMC in Field 18.
