NAVAIDs
NAVAIDs used on ground based charts will show the appropriate symbol accompanied by a data box that contains the facility name, frequency, identifier and Morse code. A NAVAID box with a heavy line indicates the primary NAVAID used for the approach.
NAVAIDs used on GPS based charts show the appropriate symbol identified with the name and identifier.

Primary NAVAID - LOC Secondary NAVAID - VORTAC Primary NAVAID - NDB/DME Secondary NAVAID - NDB/DME NAVAID - ILS Approach NAVAID - RNAV Approach Area Navigation (RNAV) Waypoints Waypoints are shown with the waypoint symbol accompanied by the five letter identifier. If an RNAV waypoint is collocated with an intersection, DME fix, or NAVAID, the appropriate Intersection, DME fix, or NAVAID symbol will be charted. ELIZE On RNAV (RNP) charts, any requirement/capability notes are depicted below the fix/waypoint/NAVAID name. When the required RNP lateral accuracy value for any approach segment other than final approach (e.g. feeder, initial and/or intermediate or missed) are less than standard (RNP 2.00 for feeder, RNP 1.00 for initial and/or intermediate and missed), a note stating the required RNP value may be placed adjacent to the applicable fix at the beginning of the Feeder Route (or annotated in the PBN box). If there is more than one lateral accuracy value within these portions of the procedure, the lowest value is annotated. These notes will take the form “RNP 0.XX, or Min RNP 0.XX” and will be located in close proximity to the relevant fix name (or be identified in the PBN Box). SHNON (RNP 0.50)

Localizer Depiction
The localizer is depicted in the Planview using the following symbol. The size of the charted localizer symbol does not serve as an indication of the service volume.
