I am replying mostly out of courtesy to those posing questions. I realise that some will be unmoved by anything I write.
Not at all, your posts are very well informed and constitute a convincing case for not mandating the carriage of transponders by gliders in VMC. Whether the case is sufficiently persuasive is a debate for another day, but it is enough that the CAA were clearly persuaded for the time being.
I for one am certainly very grateful to you for opening my eyes about gliding. We would all be poorer were your activities restricted unnecesarily.
That said, I hold that in IMC you are a danger to every other user of the airspace; you seem convinced you are a special case.
Please tell me why those who wish to enter cloud cannot carry one of the new breed of compact transponders and turn the thing on when ever they enter cloud?
