Helinut,
I think that would be a rather dangerous assumption.
I cannot see what is "dangerous" about my assumption. I believe that Sussex Ambulance Service provide 25% of the funding to the current joint police/air ambulance operation. It is highly unlikely that they will continue to provide this money if there is a separate dedicated air ambulance operating in the same area. The shortage of money within the British National Health Service (NHS) is already well known.
If that 25% funding is removed, then Sussex Police are going to have to increase their contribution by about the same amount, in order to continue the operation as a dedicated police air support unit. How are they going to find that money when the British Home Office has already indicated its intention to substantially reduce the central government funding to police services in the 2008/9 financial year?
