Controlled Airspace and Radar Coverage - 1967
click to see this area enlarged

This chart, from the 1966-67 DCA Civil Aviation Report, shows the extent of controlled airspace and radar coverage at that time. Click here to see an enlarged view of the south-eastern corner this chart.

The darker blue 'corridors' show the extent of en route controlled airspace and closely follow the major trunk routes. As IFR navigation was entirely dependent on radio navigation aids (VAR, VOR and NDB) for track guidance, the air routes go from navaid to navaid. Major changes from the previous year include the addition of controlled airspace on the Adelaide-Darwin route, the routes to Papua New Guinea and some changes to the Tasman Sea routes.

The orange circles indicate the extent of radar coverage, at this time primary radar only, at approximately 40,000 feet. The coverage of the Adelaide radar, located at West Beach airport, is truncated to the east due to the Adelaide hills. Click here to see a photo and read more about the radar sensors.
