A VOR is a radio beacon for use by aircraft. It emits two signals. One identifies the beacon by Morse Code or recorded voice, the other is a continuous signal that rotates and varies in phase with the first. Using a special receiver, that resolves the phase difference, the direction to the beacon can be displayed. Knowing which beacon you tune into and its position on a chart, it is possible to plot a position line. Crossing it with other beacons will give a position.
Alternately, you can just fly towards it and use it as a way point.

How does the Vor work for us to find the direction?
Vor is an abbreviated form of VHF Omni-directional Range and is a kind of radio navigation system for aircraft that emanates two types of signals - one directional and the other a 360 degree radial omni-directional. The Phase comparison gives what radial you are on by the position of the needle while DME determines the distance based on timing. It kind of works like a GPS.
What is a vor?
V(ery high frequency) O(omni) R(ange). VOR consists of a four antenna system that transmits voice (automatic terminal information service), identification (to identify the VOR) as well as azimuth information to aircraft. The VOR may be stand alone or used in conjunction with a TACAN ( Tactical Air Navigation) system. This configuration is know as the VORTAC.
What is the maximum range for a VHF radio?
VHF is in the range 30 to 300 MHz.
How many channels has the VOR system?
The VOR (VHF Omnidirectional Range) system typically operates with 1,020 channels. Each channel is spaced 50 kHz apart, allowing for clear communication and navigation signals for aircraft. This extensive range of channels helps reduce interference and provides pilots with reliable navigation options.
What is the typical maximum range for VHF communication in aircraft?
VOR ground stations transmit within a very high frequency band. VHF is subject to line of sight restrictions therefore, its range caries in direct proportion to the altitude of receiving equipment. Generally at about 1000 feet above ground the signal distance is 40 - 45 miles and the distance increases with altitude.
What is Radials in VOR?
Radials in VOR (VHF Omnidirectional Range) are specific magnetic bearing lines that extend outward from a VOR ground station. Each radial is identified by a degree heading from true north, allowing pilots to navigate and determine their position relative to the VOR station. For instance, the 090 radial points east, while the 270 radial points west. Pilots use these radials to intercept courses and ensure accurate navigation.
How does vor provides bearing information?
VOR (VHF Omnidirectional Range) provides bearing information by transmitting a signal that aircraft can use to determine their position relative to the VOR station. The VOR station emits a signal that includes a reference phase and a variable phase, which allows the aircraft's receiver to calculate the angle or bearing to the station. Pilots can read this bearing on their cockpit instruments, enabling them to navigate accurately by flying to or from the VOR station. This system is crucial for maintaining situational awareness and ensuring safe navigation in aviation.
What is meant by the aviation term VOR?
VOR stands for VHF Omnidirectional Range, a type of radio navigation system for aircraft. It provides pilots with a way to determine their position and stay on course by receiving radio signals from ground-based VOR stations. These stations transmit signals in all directions, allowing pilots to use their onboard instruments to navigate by following specific radials. VOR is a critical component of modern air traffic control and helps ensure safe and efficient flight operations.
What is the name of all Antennas on Cessna 172?
The Cessna 172 typically features several antennas, including the VHF communication antenna, VOR (VHF Omnidirectional Range) antenna, and the transponder antenna. Additionally, some models may have an ADF (Automatic Direction Finder) antenna and a GPS antenna. The specific configuration can vary depending on the aircraft's avionics package and modifications.
Can you use a VHF radio to call a walkie-talkie?
A walkie-talkie refers to a portable radio. VHF range is usually 136 to 172 mhz and a portable will pick up if tuned to this range.
What important factors must a navigator consider when selecting vor sites?
VOR stations rely on "line of sight" because they operate in the VHF band-if the transmitting antenna cannot be seen on a perfectly clear day from the receiving antenna, a useful signal cannot be received. Also, VOR stations in areas of magnetic compass unreliability are oriented with respect to True North.
How do you generate the radiation pattern of Very high frequency Omni Range?
The VOR works by allowing an aircraft receiver to compare a reference timing signal with a directionally phased difference signal. Originally, the difference signal was generated with a rotating antenna. Today, it is generated electronically, and there are no moving parts.
