VOR, a very high frequency (VHF) omni-directional radio range is an en-route and terminal radio-navigational aid. It utilises a ground transmitter beacon and an aircraft receiver together with some form of cockpit display. VOR gives the pilot horizontal position information in the form of magnetic bearing of the aircraft to or from the ground beacon, but does not give distance or altitude information. In this article WINGS looks at the way the aid works and how it is set up in New Zealand.
