Hi Scott,
We are going to replace the FDP computers sooner than that!! NAS is moving to Swanwick in 2007 so the hardware will be new. NATS is in collaboration with SATCA (Spain) who will supply a new system (including a new FDP system) for Scotland which should be in operation in 2008. SATCA will also supply the system to replace Swanwick and that is scheduled for 2011/2012. We will be running NAS until then.
