A very high frequency omnidirectional range station (VOR) [1] is a type of short-range VHF radio navigation system for aircraft, enabling aircraft with a VOR receiver to determine the azimuth (also …

Aug 31, 2025 · Learn how VORs (VHF Omnidirectional Range) work in aviation, including their types, uses, and limitations. Discover why VOR navigation remains a critical backup to GPS.

Feb 20, 2018 · Most VORs have distance measuring equipment (DME) or tactical air navigation equipment (TACAN) installed within the VOR station. When a VOR is collocated with DME, it's …

Sep 8, 2022 · What Are VORs? VOR is a type of navigation aid (navaid) that uses very high frequency radio signals emitted by radio beacons. VOR stations broadcast three letter identifiers in Morse code.

Aug 9, 2025 · VOR signals operate on line-of-sight principles, meaning terrain, buildings, or other structures can block or distort them. Signal strength diminishes with distance, particularly at lower …

Dec 1, 2025 · VOR is a type of nonsatellite, groundbased navigation aid. The signal pattern forms 360 discrete bearings, known as radials, each corresponding to a magnetic direction from the station (for …

Apr 25, 2023 · The VOR MON program is optimizing the VOR network in the contiguous United States (CONUS) to provide a backup conventional service in the event of an unplanned Global Positioning …

Mar 12, 2025 · VOR is a short-range radio navigation aid. Pilots can check their location to cofirm they are remaining on course.

Click and drag on the VOR station or airplane. As they move around, you can see the instruments display the airplane's heading and radial/course information relative to the station.

Pilots identify a VOR by pulling the “squelch” knob out and adjusting volume on the nav radio until the VOR morse code or voice identification can be confirmed.
