We recently sought feedback on proposed amendments to 4 Manuals of Standards (MOS) that will ensure radio altimeters (radalts) operate reliably in the presence of radio frequency transmissions from 5G.
Date
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.
