Have your say on the ADS-B proposal


If you fly in controlled airspace, this proposal will apply to you.

As part of the New Southern Sky (NSS) programme, Airways is moving to Automatic Dependent Surveillance - Broadcast (ADS-B). The current secondary radar service will be replaced by ADS-B as the main source of surveillance information for separation of aircraft in controlled airspace.

The CAA proposed rule change would make ADS-B mandatory for all aircraft in controlled airspace below Flight Level 245 from 31 Dec 2021.
