I don't agree that it will be an inconvenience - when operating in the area you should be wearing the listening squawk or be talking to Solent. That is the best practice way of flying in this country as it is good to have a second pair of"eyes" on the ground to stop you straying too close to CAS. How hard is it to dial into 120.225 and wear 0011? you don't even have to talk to anyone!
The trial is meant to reduce infringements but I am struggling to see how. It is "suggested" that pilots contact Solent or use 0011. It is not mandatory so I'm struggling with the point. What is the success measure?
The CAA have apparently been to GA airfields to talk to them about the trial but they haven't been to mine. Considering the trial commences on 01/08, I have seen little detail.
