VOR approaches
Minor revision 8/09/06
VOR approaches are the mainstay of the Instrument system. They differ from a VOR/DME approach in that there is no distance information available to the pilot.


applications
Like the NDB / ADF there are several applications for the in light aircraft cross country VMC navigation. The applications briefly described below will be detailed in the 'Using the ' module.

VOR Radio Navigation
VOR stands for Very High Frequency Omnidirectional Range. It is a radio transmitter capable of sending signals resembling the spokes of a bike wheel.

VHF OmniRange ()
Technology / Aviation / VHF OmniRange (): A ground-based navigation aid transmitting very high-frequency (VHF) navigation signals 360 in azimuth, on radials oriented from MAGNETIC NORTH.

VOR Cone-of-confusion indications:
(1) Size of a VOR cone is negligible, meaning that station passage can be used as a recognizable fix
(2) HSI VOR bearing pointer will be removed when within the cone ...

test facility (VOT). A ground facility which emits a test signal to check receiver accuracy. Some VOTs are available to the user while airborne, while others are limited to ground use only.
VOT. See test facility.

VOR
The VHF omnidirectional range (VOR) navigation system has been in widespread use in the United States since the 1950s. However, it is being replaced by GPS.

(VHF Omnidirectional Range) A land-based radio navigational system. A station transmits a signal that the receiver can use to calculate its postion relative to or from the station.

VOR: VHF Omni-Range. A radio transmitter used for navigation. A companion receiver in the airplane provides an indicator that shows the direction from the station to the airplane.


A ground-based electronic navigation aid transmitting very high frequency navigation signals, 360 degrees in azimuth, oriented from magnetic north. Used as the basis for navigation in the National Airspace System.

VOR (VHF Omnidirectional Range) Ground- based radio navigation aid. More than 1,000 VORs electronically define Victor Airways and Jet Airways, 'highways in the sky.' Most IFR and many VFR flights follow airway routes.

- VHF OmniRange. A ground-based navigation aid transmitting very high frequency (VHF) navigation signals 360 in azimuth, on radials oriented from magnetic north.

VOR, ILS, NDB, VASI, DME, MLS, are different navigation aids and need periodic flight inspection.

Windsocks: Socks that need darning.
Yankee: Any pilot that asks Houston tower to "Say again." ...

Very High Frequency Omni Directional Range. A ground-based electronic navigation aid transmitting very high frequency navigation signals, 360 degrees in azimuth, oriented from magnetic north.

VOR check-If your airplane is IFR equipped within the preceding 30 days the VOR equipment must be operationally check in accordance with FAR 91.171. Remember you should also maintain a record in the airplane of this.

(See .)
TERRAIN FOLLOWING- The flight of a military aircraft maintaining a constant AGL altitude above the terrain or the highest obstruction. The altitude of the aircraft will constantly change with the varying terrain and/or obstruction.

A plain old VOR receiver can get you into trouble, too. It is altogether too common for pilots approaching a VOR to have their heads “down and locked” — ...

This tracking a radial to a station is the primary means by which pilots the world over navigate from one section of a country to another, and finally to any destination airport.

VOR
In this particular aircraft a VOR display is mounted to the left of the Turn and Bank, below the directional gyro.
Engine Instrument Cluster
Other instruments are mounted to the left of the flight instruments.

Your retrospective on the ("The Day The Waypoints Died," April 2012) was of interest in a reverse sort of way.

Navigation relative to radio station, providing, for example, of relative bearing, range, lateral deviation, and glideslope; Examples include VOR, TACAN, and PLS.

A NAVAID can be a (very high frequency omni-directional range beacon), NDB (non-directional beacon), or GPS waypoint. In order to be abeam a NAVAID you have to have instrument confirmation that you next to it.

Of course, someone is going to say, “Yeah, but we can always tune in a VOR.

VERY HIGH FREQUENCY (VHF) OMNIDIRECTIONAL RANGE () - A radio transmitter facility in the navigation system radiating a VHF radio wave modulated by two signals, the relative phases of which are compared, resolved, ...

Very High Frequency Omnidirectional Range (VOR) Station − A ground-based radio navigation aid transmitting signals in all directions. A VOR provides azimuth guidance to pilots by reception of electronic signals.
