It does not seem to be such a problem in many other countries as it seems to be here. All I was asking was for those who wish to have the right to exclude others perhaps ought to consider going by the rule book - just as GA should. As for paying for the service I would submit that those who want the CAS should make the service available without charge because it is ACCESS to that airspace that is being requested and you pay nothing for that chunk of airspace. If you paid by the volume you wish to have then there may be a case for charging for entry but as you dont it seems to be a bit of a spurrious argument. There is a lot of castigation of GA and in some cases rightly so but not all GA is made up of weekend "bumblers". You know as do I that anything that is not classed as military or CAT is GA so a very wide range is covered.
