I thought that this had been done to death by Timothy and others on many occasions in the past, so I am having difficulty understanding why it is being raised once again. I hope you're not just picking fights Timothy
If you are prepared to accept the 2 tonne MTOW cutoff for Eurocontrol charges in principle (not all are), the rest of the problems that Timothy describes are brought about by the UKs rather odd mangling of the concept of IFR and VFR. This mangling manifests itself in a couple of obvious ways:
1) The IMC rating and the consequent rash of uncontrolled IMC flights that operate outside "the system", often inexpertly flown but under IMC conditions.
2) The lack of VFR at night.
My recipe for a better system:
A) Abandon the IMC rating
B) Strengthen the distinction between VFR flights (essentially uncontrolled) and IFR flights (essentially within "the system") to bring them into line with the rest of the civilised world
C) Enable the concept of VFR at night.
This wouldn't cause Timothy to stop whinging about his Eurocontrol charges but it would ensure that IFR flights received a service which was always worth the money and would provide VFR boys with the FIS they so richly deserve.
All we need then would be to redesign our airspace system away from the historically-based mess that it is at the moment, into something more like the US or Germany.
Don't hold your breath.
