Seeking feedback on proposed changes to Part 172 MOS

Date published: 26 September 2022

Have your say

We are seeking comments on an amendment to the Part 172 Manual of Standards (MOS) that would:

  • enable electro-optical technology (known as visual surveillance system or VSS) in the provision of aerodrome control services
  • address a gap in the control tower sight line requirements, in situations where a new runway is commissioned, or an existing runway is modified at an aerodrome with an existing aerodrome control facility
  • remove standards that replicate standards already specified by the International Civil Aviation Organization (ICAO).

Provide your comments via the Consultation Hub by 24 October 2022.
