Finds navaids operating on a given frequency. For VOR-family navaids, frequency is in MHz. For NDB-family, frequency is in kHz. Results are sorted alphabetically by identifier.
Looks up navaids by identifier (e.g. "BOS", "JFK"). Multiple navaids can share the same identifier (e.g. an NDB and a VOR). Returns an empty array if no match is found.
Looks up the single navaid sharing the given identifier that lies nearest to a geographic position. Multiple navaids can publish the same identifier (a co-located NDB and VOR/DME, or two stations far apart that reuse a code); this disambiguates them by proximity to a known point such as a map-click location or an adjacent route waypoint.
Returns the nearest matching navaid by great-circle distance. When
toleranceNm is provided, matches farther than that distance are
excluded and the method returns undefined if none qualify. When
toleranceNm is omitted, the nearest match is returned regardless of
distance. Returns undefined when no navaid carries the identifier.
Navaid identifier (case-insensitive).
Latitude of the reference position in decimal degrees (WGS84).
Longitude of the reference position in decimal degrees (WGS84).
OptionaltoleranceNm: numberOptional maximum great-circle distance in nautical miles. When omitted, the nearest match wins regardless of distance.
The nearest matching navaid, or undefined when none match or none fall within toleranceNm.
Finds all navaids of the given type(s). Results are sorted alphabetically by identifier.
Finds navaids nearest to a geographic position, sorted by distance. Results are filtered by max distance and limited to the requested count.
Fuzzy-searches navaids across identifier and name. Results are scored and returned best-match first, each carrying the matched field and character ranges for highlighting.
