Often asked: What Does Vor Mean In Aviation?

What is a VOR in aviation?

The Very High Frequency Omni-Directional Range ( VOR ) is a ground-based electronic system that provides azimuth information for high and low altitude routes and airport approaches.

How does a VOR work?

A VOR ground station uses a phased antenna array to send a highly directional signal that rotates clockwise horizontally (as seen from above) 30 times a second. It also sends a 30 Hz reference signal on a subcarrier timed to be in phase with the directional antenna as the latter passes magnetic north.

Do pilots still use VOR?

As of 2018, pilots still use VORs as a primary navigational aid, but as more and more aircraft are equipped with GPS receivers, VORs most likely will be retired from use.

How do pilots use VOR?

The VOR indicator can give the pilot many types of information about his or her position relative to the station. For example, by using two different VOR frequencies, a lost pilot can find out exactly where he is. If you have two VOR indicators, tune each one to a different VOR frequency.

What does VOR stand for?

‘ VOR ‘ stands for ‘Very High Frequency Omnidirectional Range’.

What is Volmet in aviation?

OLMET, or meteorological information for aircraft in flight, is the term applied to a worldwide network of radio stations that broadcast TAF (Terminal Area Forecast). In some countries, VOLMET stations broadcast on VHF frequencies too.

Is VOR being phased out?

Under the plan, 74 VORs are set for decommissioning through Phase 1, which is ongoing through 2020. Under Phase 2, which is to take place between 2021 and 2025, 234 more VORs will be decommissioned.

How do you identify a VOR?

The only positive method of identifying a VOR is by its Morse Code identification or by the recorded automatic voice identification which is always indicated by use of the word “ VOR ” following the range’s name.

Is VOR obsolete?

The VOR will eventually fade away and become obsolete because it’s expensive for the government to maintain and GPS based NextGen systems offer so much accuracy and flexibility. But just as ADF has survived for 80 years, so also will VOR persist for quite a long time more.

Is VOR required?

Although a VOR can be used to satisfy the navigation equipment requirements, a VOR is not specifically required. GPS is a suitable radio receiver which can be used for both IFR and VFR operations instead of or in addition to VOR. In some areas of the world, an NBD/ADF receiver would suffice.

Are VOR magnetic or true?

VOR degrees are magnetic, not true, so you can read your magnetic course for that location right from the VOR rose. Again, the difference between the true course you’ve drawn on your chart and the magnetic course that runs through the VOR rose is the magnetic variation.

Is a VOR required for IFR?

The federal aviation regulations, specifically 14 CFR 91.205, detail the equipment needed for different flight conditions, such as day VFR, night VFR, IFR, etc. The answer is obviously no for the pilot flying IFR solely (from a legal perspective) in reliance on the VORs.

What is the difference between VOR and Vortac?

TACAN stands for TACtical Air Navigation, a military system that is similar to VOR but with higher accuracy. A VORTAC combines the VOR and TACAN in one location. Civil users will use the VOR signals which have the same performance as ordinary VOR signals. In addition they use the DME from the TACAN.
