Well, FL, interesting post. They don't seem to know what the CAA are up to either.
When one reads some of the threads on here, then looks at AAIB reports, then looks back at threads on here, it seems that the airlines are doing what they want to and the CAA are a rubber stamp agency. I hate to be a conspiracy theorist, bu the only thing that really fits is the airlines deciding GA must use Mode S for their purposes, and the CAA are rubber stamping that decision too.
So if the people at that meeting are correct and this is going through no matter, is the only solution then a judicial review? Expensive stuff I would think. And I am sure judges doing these reviews are hyper-intelligent beings, I am sure they can be swayed by the regulator playing the safety card, and I bet that would be their gambit there too.
