Jngler 909
Within the UK most (even many minor) airfields have an Air Traffic Zone. Whilst this doesn't have the status of regulated airspace (it assumes the status of the airspace within which it is located). This includes many regional airports and virtually all military airfields (who also have slightly larger MATZs but this is only recognised by Mil pilots)
ATZs are established to protect a/c during landing circuiting and take-off, and any pilot who wishes to transit the ATZ is required to contact the controlling authority on RT... this may be anything from an AGS to a full-blown IFR ATC setup.
I agree the gold-plated option would be to have CAS, but there are many lobbies competing to preserve their rights/freedoms. Generally the system is IMHO a good compromise (although there are always borderline cases where a little more protection would be nice!)
