I'd question the wisdom of flying non-radio in an area as dodgy as this
Says the bloke who admitted flying non-radio 'a fair bit of the time'.
What exactly is this 'dodgy' bit your talking about. It's Class G airspace, you don't have to be equipped with a radio. If the CAA started telling the flying fraternity that they had to be radio equipped regardless of a/c type and airspace used, the noise would be deafening, it'd sound like a slaughterhouse on porky pig day! Why don't you email that comment to the BGA and see what response you get.
The airspace round Cov isn't dodgy, it's just Class G, there's a difference.
