MG,
I sympathise with your experiences with the CAA, but as licenced and fortunately employed pilot at present I find them alot easier to deal with than previously.
I agree that their charges are high, and do need to be justified to customers. But then, in my experience, charges made by profesional regulatory bodies often are (I refer to the various medical colleges, Royal Institute of British Arcchitects etc).
I do find you a little hard to take seriously, however, when I see your profile listing you as "from the inside of a marmite jar" and your interests as getting the brown stuff off the inside of said marmite jar. Marmite jars are brown glass anyway, and maybe until you look outside at the world beyon the lid, your view will always be tainted by brown glass.
Many have tried and many have failed to change the CAA, and only with experience will you come to realise that they work on the whole, for the whole industry, and will make every effort for the individuals with the industry. This is not to say they couldn't improve, but they aren't as bad as they may seem.
As Ex-FTE asks, you do seem to have an axe to grind. Maybe you would be better asking BALPA or IPA to represent your problem to the CAA. Good luck in a succesful outcome.
