On the 26th of May, Australia will switch off around 180 different VOR’s, NDB’s, and other ground-based Navaids. Those that escape the cull – about 245 of them – will form the basis of their new “Backup Navigation Network”, or BNN.

For International Operators, in short, Australia wants you to navigate with GNSS as your primary means of navigation. The new standards, from 26MAY, are:

  • Oceanic Routes: RNP4 if able, otherwise RNP10
  • Continental Routes: RNP2
  • SIDs and STARs: RNP1
  • Non Precision approaches: RNP APCH (ie. RNAV(GNSS)

CASA will issue an exemption if you have an existing RNAV1 or RNAV2 approval based on GNSS from your National Authority, but you must have either the above RNP capabilities, or the exemption, to operate in Australian Airspace from 26MAY.
