The CAA is working with airports, ATC and GA flying organisations to help reduce the risks of infringements in the Southampton Control Zone and the Solent Control Areas. GA pilots are being asked to collaborate in this new initiative set to start on 1 August 2016
The CAA said this is not an airspace change but pilots are being asked to co-operate with the 10 week trial.
