perhaps I didnt express my self very well. Yes, I know that to reduce CAS floor to 2500amsl would not work, for any number of reasons; (Not least the environmental noise impact!) I was trying to illustrate a point -that in an effort to optimise the routeing structure, we may see expansions of CAS which would be of benefit to the Air Transport industry, but perhaps to the detriment of GA/Private flying. My exaggerated lowering of the South Coast floor of TMA was to stimulate awareness of what could happen.
With regard to the spectre of navigation fees, then I can only guess at the impact on GA. I see it as twofold. Firstly, would the average PPL communicate as readily with the nearest ATSU if he/she was going to get billed for a RIS/RAS? Would this have an impact on flight safety? Secondly, if the said pilot DID pay up and look big, would he/she be able to afford to fly as often? Would the implied lack of recurrency further imapir flight safety?
I dont profess to be any kind of expert, but it does seem to me that Apathy rules OK, (Who Cares!)I am not a rabble rouser, but I have come to the conclusion that if we dont wish to see our creaking GA infrastructure totally collapse, then we all need to join AOPA or the PFA or GAPAN etc. Otherwise when we go to the site of our airfield all we will find is a cinemaplex, or shopping mall.
