Navigational Aid Legend

Navaid identification is given in shadow box when navaid is airway or route component, with frequency, identifier, and Morse Code. DME capability is indicated by a small "D" preceding the VOR frequency at frequency paired navaids. VOR and VORTAC navaid operational ranges are identified (when known) within the navaid box except on USA and Canada charts. (T) represents Terminal; (L) represents Low Altitude; and (H) represents High Altitude.

On High/Low altitude Enroute Charts, geographical coordinates (latitude and longitude) are shown for navaids forming high or all altitude airways and routes. On Area Charts, geographical coordinates are shown when navaid is airway or route component. Some L/MF navaids are combined in the shadow box even though they are not part of the airway / route structure, except on US and CA charts. They are used for course guidance over lengthy route segments when airway/track is designated into a VOR.

When VOR and TAC/DME antennas are not collocated, a notation "DME not Co-located" is shown below the navaid box.

Off-airway navaids are unboxed on Low and High/Low charts. TACAN/ DME channel is shown when VOR navaid has a frequency paired DME capability. When an L/MF navaid performs an enroute function, the Morse Code of its identification letters are shown.

When TACAN or DME are not frequency paired with the VOR, the TACAN is identified separately. The “Ghost” VOR frequency, shown in parentheses, enables civilian tuning of DME facility.

The navaid frequency and identification are located below the location name of the airport when the navaid name, location name, and airport name are the same.

LOC, SDF, LDA and MLS navaids are identified by a round cornered box when they perform an enroute function. Frequency identification and Morse Code are provided. DME is included when navaid and DME are frequency paired.
