The problems have occurred because crazy differences like two mandatory reporting points were introduced.
I've asked this a couple of times on different (but the same
) threads to no avail - and it is a genuine question -
The report looks at a couple of busy airports in the US and Canada and they seem to have inbound VFR points/lanes and dedicated outbound tracks.
Can someone show a non-radar Class D tower anywhere (FAA, ICAO, whatever) with more than 300,000 movements a year that does not have VFR approach points/VFR routes?
