They have to get the OK first..... and if they get the helicopters in that would be a start that never happened at other bases. Estree, East Midlands, Northolt..... and do not forget the daddy of them all.... foggy RAF Colerne....
They seem to constantly select locations with a pin and wonder why the research [that should have been done before the announcement] tends to deflect them...
I suspect the fixed wing is wish list as is 20,000 movements. It gives wiggle room and may stave off a later change in mind by EFDC.
If they get a yes they can pay for the ILS etc down the line ....... it might be cheap compared to the ongoing cost of making the 30-years old P68 fully IFR. Most police and ambulance units had to have relatively simple IL systems fitted over the years so its is just a bigger version of that.
