<<But the problem is that the only abundant suitable waypoints that the GPS and the map have in common are the airfields. So a lot of flights are planned via the overheads of airfields. Not good. Maybe it's time for some IFR-like intersections to be introduced for VFR flight, at locations that are easily recognizable from the air, are listed on the map and are included in the GPS database.>>
I am an avid user of GPS, but not for flying. Surely it is possible to programme any location as a waypoint using either Lat/Long or OS grid refs? Or would that be too time-consuming?
<<Well, you could try running the airspace in a similar way to LAX class B and C and providing a consistent, easy to use radar service for all.>>
I don't know how that functions but I definitely do not like the US system of see-and-be-seen close to major airfields!
