Do terminal VORs still exist?

Do terminal VORs still exist?

The VOR MON has been retained principally for IFR aircraft that are not equipped with DME/DME avionics. However, VFR aircraft may use the MON as desired.


To get relatively accurate readings, the aircraft’s altitude should be 1000 feet per nautical mile from the station. DME information is provided by VORTAC and VOR-DME, but not by standard VOR facilities. DME information may also be provided by some ILS facilities.

How do NAVAIDs work?

Navigational Aids (NAVAIDs) VOR facilities allow the pilot to follow a designated flight path by using the aircraft’s cockpit gauges to indicate their positions. ILS transmits guidance beams to allow the pilot to land safely and efficiently.

What are the airport Navaid instruments?

Navigational Aids are a form of marker, signal or device that aids an aircraft by guiding and navigating it to its destination. It can be in the form of Instrument Landing Systems (ILS), Distance Measuring Equipment (DME), Non-Directional Beacon (NDB) or Doppler VHF Omnidirectional Range (DVOR).

Why are VORs still used?

The Very High-Frequency (VHF) Omnidirectional Range (VOR) system is used for air navigation. Though older than GPS, VORs have been a reliable and common source of navigation information since the 1960s, and they still serve as a useful navigational aid for many pilots without GPS services.

Can civilians use TACAN?

The DME portion of the TACAN system is available for civil use; at VORTAC facilities where a VOR is combined with a TACAN, civil aircraft can receive VOR/DME readings. Aircraft equipped with TACAN avionics can use this system for en route navigation as well as non-precision approaches to landing fields.

Are Ndbs still used?

The ADF/NDB navigation system is one of the oldest air navigation systems still in use today. It works from the most simple radio navigation concept: a ground-based radio transmitter (the NDB) sends an omnidirectional signal to an aircraft loop antenna.

How is a DME station tuned in?

DME is tuned by tuning either a VOR or ILS station, as applicable. Here is a DME readout on an EFIS Display. The characters “NAV1” indicate that the DME being displayed is from the No. 1 VOR receiver.

Are VORs 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.
