Summary of consultation now available – Requirements for radio altimeters due to 5G transmissions

The proposed amendments also include a Direction to foreign air transport operators under CASR Part 129, and operators holding a New Zealand AOC with ANZA privileges, to the same effect, as these operators are not covered by the 4 MOS amendments.

We’ve published the summary of consultation on our Consultation Hub.

We received 14 responses which provided feedback on the following themes:

  • timeline provided to update radalts and requests to delay the date
  • impact on airline operations
  • inclusion of the RNP-AR instrument approach procedures
  • alternative means of compliance and exemptions
  • where the proposed rules apply.

Next steps

We recently emailed operators to advise:

  • we have removed RNP-AR instrument approach procedures from the list of operations which require fitted radio altimeters to be compliant with the interference tolerance curves in the relevant FAA ADs
  • no individual exemptions will be provided for operators who have not upgraded their aircraft
  • we are working with the Australian Communications and Media Authority (ACMA) to determine whether aircraft operators can be exempt from complying with the new radalt requirements at an aerodrome until a 5G station starts operating near that aerodrome.

We will proceed with the proposed amendments to the Part 91, 121, 133 and 135 MOS, and the separate Direction.
