NDB (Non-Directional Beacon) navaid records defining the location, frequency, and characteristics of NDB ground stations
ARINC 424 Section DB records. Includes both enroute NDBs and terminal NDBs. AIRPORT_ICAO_IDENTIFIER and ICAO_CODE are null for enroute NDBs; they are populated for terminal NDBs associated with a specific airport.

| Field | Type | Description | Units | Enum |
|---|---|---|---|---|
| recordType ← RECORD_TYPE | CifpApproachRecordType | Indicates whether the record is a standard record or a tailored record |
| |
| customerAreaCode ← CUSTOMER_AREA_CODE | CustomerAreaCode | Geographic area of the world to which the record applies, used for data partitioning |
| |
| sectionCode ← SECTION_CODE | CifpNdbNavaidSectionCode | ARINC 424 section and subsection code identifying the record type; DB indicates enroute NDB navaid |
| |
| airportIcaoIdentifier ← AIRPORT_ICAO_IDENTIFIER | String | ICAO identifier of the airport with which this NDB is associated; null for enroute NDBs not associated with a specific airport | ||
| icaoCode ← ICAO_CODE | String | ICAO region code associated with the airport identifier for terminal NDB records; null for enroute NDBs | ||
| ndbIdentifier ← NDB_IDENTIFIER | String | Two- or three-character identifier assigned to the NDB navaid | ||
| icaoCode2 ← ICAO_CODE_2 | CifpNdbNavaidIcaoCode2 | ICAO region code associated with the NDB identifier, used to uniquely qualify the NDB within the global dataset | 20 values
| |
| continuationRecordNo ← CONTINUATION_RECORD_NO | String | Continuation record number; 0 or 1 indicates the primary record, values 2 and above indicate continuation records with additional data | ||
| ndbFrequency ← NDB_FREQUENCY | String | Operating frequency of the NDB navaid, stored as a five-digit integer representing frequency in kHz (e.g., 05300 = 530.0 kHz) | kHz | |
| ndbClass ← NDB_CLASS | NdbClass | Classification of the NDB indicating power class and any additional equipment or operational capabilities. First character is power class (H=High power), subsequent characters indicate additional capabilities (W=with weather broadcast, M=with compass locator, O=without voice, L=low power locator) |
| |
| ndbLatitude ← NDB_LATITUDE | String | Latitude of the NDB navaid in encoded format: hemisphere (N/S), degrees (2 digits), minutes (2 digits), seconds and decimal seconds (6 digits, implied decimal after first 4) | degrees | |
| ndbLongitude ← NDB_LONGITUDE | String | Longitude of the NDB navaid in encoded format: hemisphere (E/W), degrees (3 digits), minutes (2 digits), seconds and decimal seconds (6 digits, implied decimal after first 4) | degrees | |
| magneticVariation ← MAGNETIC_VARIATION | MagneticVariation | Magnetic variation at the NDB location, encoded as direction (E=East, W=West) followed by a four-digit value in tenths of degrees (e.g., E0070 = 7.0 degrees East, W0150 = 15.0 degrees West). E0000 and W0000 both represent zero variation. | degrees | 44 values
|
| datumCode ← DATUM_CODE | String | Geodetic datum code indicating the horizontal datum to which the latitude and longitude coordinates are referenced (e.g., NAR = North American 1983) | ||
| ndbName ← NDB_NAME | String | Full name of the NDB navaid station | ||
| fileRecordNo ← FILE_RECORD_NO | String | Sequential file record number assigned to this record within the CIFP data file, used for referencing and ordering | ||
| cycleDate ← CYCLE_DATE | String | AIRAC cycle date when this record was last updated, encoded as a four-digit value where the first two digits are the last two digits of the year and the last two digits are the AIRAC cycle number within that year (e.g., 1605 = year 2016, cycle 5) |
