_Very High Frequency Omni-Directional Range - AviatorsBuzz (1)

The Very High-Frequency Omni-Directional Range (VOR) is a type of short-range radio navigation system for aircraft, to determine its position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons.

  • Operates on VHF band from 108.00 to 117.95 MHz.
  • The system is made up of a ground component and an aircraft receiver component.
  • Ground stations are located both on and off airports to provide guidance
    information to pilots both enroute to and during arrival and departure.
  • Aircraft equipment includes a VOR antenna, a VOR frequency selector, and a cockpit instrument. The instrument type varies but consists of one of the following: an Omni-Bearing Indicator (OBI), Horizontal Situation Indicator (HSI) or a Radio Magnetic Indicator (RMI), or a combination of two different kinds.
