With the naysayers above, it does seem a bit off to have a go at what is an extraordinary step forward for a GA airport that's been around for 75 years in busy uncontrolled airspace. What other UK GA airport out there today would cough up £4m or so and pay the costs of running the primary and secondary radar to ensure a safer environment for all who travel to and through that zone? Yes, they have aspirations for some commercial stuff, but this is about protecting GA, by far the greatest users of that airspace. They should be commended for taking this huge step forward, at vast expense, to make the sky a little bit safer for all of us. It's doubtful that there will be a full, all day, every day service from the start, but a gradual stepping up of capability once all have the training, experiance etc. behind them. It's a progressive, forward-thinking airport spending a lot on infrastructure right through a period of economic doom since the new owners bought it in 2007. That said, some of the other key GA/regional airrports around London continue to spend large sums on enhancing their airrports too - thank goodness people are still spending money at these places.
