soaringhigh650, what makes you think UK airspace is designed? Basically it evolved and much of the airspace is simply historic. We don't have DC3s on public transport over here any more but the airspace would be suited to them. Modern twin jets climb at 750-1000' per nm and Constant Descent Approaches are what one would hope to see, i.e. 3 degrees or 330'/nm. Fortunately last August the CAA having acknowledged that there are large areas of unused airspace acted promptly and came up with a method of getting rid of old and unused airspace without long and expensive Airspace Change Proposals. I hear NATS accepted this view also and have been looking to work with GA groups to release airspace. Any one can sponsor a change now without incurring great costs, perhaps someone will help out by sponsoring an ACP to raise the base here by 2,000' and solve the problem?
