Service to non towered fields
I'm a little lost in this debate but to clarify one point.
In the US there is scheduled service into non towered fields and some of these fields have are out of center radar coverage.
Massena New York, (MSS) is a case in point. You can legally have a plane, in IMC, executing the ILS while you have local traffic -legal in the pattern. Boston center radar will not get you below 2500. The only "service" so to speak is pilots on the UNICOM.
Most US fields and canadian fields do not have UNICOM operators providing information in my experience. (Only come across this once, the local air cadets at Lachute)
Also - there are a lot of towerd fields where the tower has no radar. We had a mid air at KCDW, night VMC, a few years back when the tower was operating.
