What is VOR service volume?
VORs (VHF Omni-directional Range) provide positive course guidance within a standard service volume. These service volumes define the altitudes and distances protected for use on random or non-published routes.
What is a VOR beacon?
In radio navigation, a VOR/DME is a radio beacon that combines a VHF omnidirectional range (VOR) with a distance measuring equipment (DME). The VOR allows the receiver to measure its bearing to or from the beacon, while the DME provides the slant distance between the receiver and the station.
What does it mean if a VOR is not monitored?
Unmonitored, as used in this order, means that the personnel responsible for monitoring the facility have lost aural and visual monitoring capabilities and cannot observe the status of the facility.
How do I know my VOR type?
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.
How far out can you pick up a VOR?
The VOR Navigational Station Terminal VORs are designed to be clearly received up to 25 nautical miles from the station at altitudes of 1,000 feet agl through 12,000 feet agl. Low-altitude VORs are meant to be used from 1,000 feet agl through 18,000 feet agl at distances of up to 40 nm from the station.
What VOR stand for?
VHF Omnidirectional Radio Range
Definition. VHF Omnidirectional Radio Range (VOR) is defined as VHF Omnidirectional Radio Range, an aircraft navigation system operating in the VHF band.
What does AP mean in a notam?
| CONTRACTIONS | DECODE | SOURCE |

| APP | Approach Control | ICAO |
| ARFF | Aircraft Rescue and Fire Fighting | FAA |
| ARR | Arrive, Arrival | ICAO |
Why can’t all airports be used as alternatives?
[Instrument Procedures Handbook, pg. 2-11] Not all airports can be used as alternate airports. An airport may not be qualified for alternate use if the airport NAVAID is unmonitored, is Global Positioning System (GPS) based, or if it does not have weather reporting capabilities.
When a navigational aid’s operational status cannot be monitored at the controlling or monitoring facility, but all indications or reports are the facility is operating normally, Technical Operations personnel must ensure the origination of a NOTAM placing the aid in an unmonitored status.
What does unmonitored mean in a security category?
Unmonitored, as used in this order, means that the personnel responsible for monitoring the facility have lost aural and visual monitoring capabilities and cannot observe the status of the facility. It does not refer to the automatic monitoring feature. b.
When to use unmonitored in a NOTAM?
When issuing a NOTAM describing a facility as unmonitored, do not use the category of monitor, only the contraction UNMON. EXAMPLE- !DCA LDN NAV VOR UNMON d. If the NAVAID is reported as being out of service, the unmonitored NOTAM shall be canceled.
Are there any unmonitored navaids in the NAS?
UNMONITORED NAVAIDs a. All VOR, VORTAC, and ILS equipment in the NAS have automatic monitoring and shutdown features in the event of malfunction.
