For your info there is no EASA AMC/GM to supersede this CAP and it remains a national document, albeit adopted as best practice by a number of European states.
There are virtually no Scheme of Charges figures associated with CAP1122; I recall less than £1000. The real cost is in buying in expertise from IFP designers, safety case authors and Airspace Change Proposal managers. £50,000 outlay with no guarantee of success. That said, money from Europe channeled through the EGNOS promotion fund has helped.
Oh you worked on this!? NICE! Finally someone with some sense working on things that matter to us little guys!
Thank you for letting me know - I appreciate this. I knew the (around) £50k figure, which I actually don't think is crazy expensive. It really is a drop of water in the sea when comparing it to the cost of the infrastructure for VOR/DME/ILS approaches, which was why I spent some time trying to find ANY GNSS/LPV approaches, but at the time I believe that there were only a couple, and those were at licensed airfields only. I don't believe that this has changed much for GA.
I have done some GNSS approaches in France and NZ at untowered airfields and thought it incredible, I couldn't believe that the UK wasn't adopting it! From a safety point of view, if nothing else! There have been several crashes in the last few years, mostly highly experienced pilots scud-running / doing home-made approaches to airfields whilst in very marginal conditions. I often wonder had these airfields have GNSS/LPV or other approaches, if these accidents would have happened. (regardless of pilot error / piloting attitude / company pressure or any other factors, having a proper GNSS approach would without any doubt in my mind have reduced the risk quite considerably)
