Here's what a VOR station looks like:The frequency range for a VOR is between 108.0 MHz and 117.95 MHz. As with any system, VORs come with some potential problems.
Each R, C, or L represents the position of an aircraft which has selected the same VOR frequency, the same (90-degree) radial, and its corresponding CDI needle indication. A VOR system is made up of a ground component and an aircraft receiver component. Every VOR is oriented to magnetic north (more on this in a bit), and emits 360 radials from the station. Pilots fly certain radials to or from VORs as a primary way of navigating. Get Boldmethod flying tips and videos direct to your inbox. A large number of VOR facilities are located on airport property, allowing even student pilots to fly directly to a VOR to find the airport easily. Obstacles, terrain, and even the slope of the earth interfere with VOR signals. The OBI, HSI, or RMI indicator in the cockpit looks like a compass or a heading indicator, with a superimposed Course Deviation Indicator (CDI) needle on it.

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.

Set the radial's direction into the OBS and turn the aircraft to fly that heading.
In its more basic form, a VOR facility can be used to go directly to an airport. Paired with DME, a pilot can determine a precise location from the station.
Once established on the heading, note the position of the CDI.

A photograph of a VOR ground station is shown below: VORs provide azimuth information (the heading of the aircraft) and are generally used during the en‑route phase of flight or on non-precision approaches to a runway. He's the author of articles, quizzes and lists on Boldmethod every week.
Also, the use of two VOR stations makes determining a precise location even more accurate by using cross-radials, even without DME. Ground stations are located both on and off airports to provide guidance information to pilots both en route and during arrival and departure.
You can look your VOR up in the FAA Chart Supplement to determine what category it is.Even though VORs have been around since the 1940s, they're not going away anytime soon.Swayne is an editor at Boldmethod, certified flight instructor, and an Embraer 145 First Officer for a regional airline. VOR stations are used all over the world. The result is a cockpit instrument (the ADF) that displays the aircraft position relative to an NDB station, allowing a pilot to \"home\" to a station or track a course fro… If it is to the right, your radial is to the right. These are also called "reference" and "variable" phases.An aircraft's VOR antenna, which is usually located on the tail, picks up this signal and transfers it to the receiver in the cockpit. https://www.boldmethod.com/learn-to-fly/navigation/how-a-vor-works
