NewModel,
I have not had time to fully absorb all the information on your website and you have obviously put in a considerable amount of time and research into your work. Many of the points you raise are already being addressed with projects like iFACTS. The implementation of Mode S will also improve productivity.
The systems currently in use are capable of "paperless" control but Flight Strips remain in use at the moment to ensure that the UK does not rely on technology too quickly. Failures still occur and the Paper system is a very important fallback. If you have a failure without backup there will be carnage.
There are many studies ongoing at the moment within Europe to improve matters but I wish you well in your efforts.
