The CAA needs to liase with the JAA and get the "IMC" rating recognised throughout Europe. Class A floors need to be raised and then a new system of low level class D airways, say up to 12,000' could be introduced allowing IMC holders to fly airways...including class D airway 'corridors' through Class A TMA's. Allow 'IFR certified' GPS to be used as primary nav in light aircraft, have a mode S dispensation (how much are these BTW? a few grand?) for private flights below 12k'. Now we've got an affordable Private IR in Europe....
Ah, the only problem I can see is a complete shake up of the European ATC system. Oh well, back to the drawing board
