It will be interesting to see how the non-NATS units get on when their legacy radar equipment is replaced by the likes of the ASR10...
What are you expecting?
I know I've been out of it for a while but it's just another primary radar. I worked a number of different radars throughout my operational days, most of which were spent with ANSPs other than NATS - each was different and had it's own strengths and weaknesses.
And, BTW, at one unit I was using far more capable kit than the nearest NATS-operated unit.
