Terminal waypoints associated with specific heliports, defining named fixes used in heliport instrument procedures (ARINC 424 Section HC)
This table contains waypoints scoped to a specific heliport identifier rather than the general terminal waypoint database. Analogous to airport terminal waypoints but for heliport operations. Latitude/longitude are encoded as hemisphere+degrees+minutes+seconds+tenths of seconds (e.g., N40514240 = N 40°51'42.40").

| Field | Type | Description | Units | Enum |
|---|---|---|---|---|
| recordType ← RECORD_TYPE | RecordType | Indicates whether the record is a standard record or a tailored record |
| |
| customerAreaCode ← CUSTOMER_AREA_CODE | CifpHeliportApproachCustomerAreaCode | Geographic area code identifying the region of the world to which the record applies |
| |
| sectionCode ← SECTION_CODE | CifpHeliportWaypointSectionCode | ARINC 424 section and subsection code identifying the record type; HC indicates Heliport Terminal Waypoints |
| |
| heliportIdentifier ← HELIPORT_IDENTIFIER | AirportIdentifier | The ICAO or FAA identifier of the heliport to which this waypoint is associated |
| |
| icaoCode ← ICAO_CODE | CifpHeliportMsaIcaoCode | ICAO regional code for the heliport identifier, indicating the ICAO geographic region in which the heliport resides |
| |
| waypointIdentifier ← WAYPOINT_IDENTIFIER | WaypointIdentifier | The five-character alphanumeric name/code of the terminal waypoint fix associated with the heliport | 9 values
| |
| icaoCode2 ← ICAO_CODE_2 | CifpHeliportMsaIcaoCode | ICAO regional code associated with the waypoint identifier, used to distinguish waypoints with the same name in different regions |
| |
| continuationRecordNo ← CONTINUATION_RECORD_NO | CifpHeliportSidContinuationRecordNo | Continuation record number; 0 or 1 indicates the primary record, higher numbers indicate continuation records with additional data for the same waypoint |
| |
| waypointType ← WAYPOINT_TYPE | CifpHeliportWaypointWaypointType | Indicates the type or category of the waypoint fix |
| |
| waypointUsage ← WAYPOINT_USAGE | String | Indicates the usage category of the waypoint, such as whether it is used for high or low altitude operations; null indicates no specific usage restriction | ||
| waypointLatitude ← WAYPOINT_LATITUDE | WaypointLatitude | Geodetic latitude of the waypoint encoded as hemisphere + degrees + minutes + seconds + tenths of seconds (e.g., N40514240 = N 40°51'42.40") | degrees | 9 values
|
| waypointLongitude ← WAYPOINT_LONGITUDE | WaypointLongitude | Geodetic longitude of the waypoint encoded as hemisphere + degrees + minutes + seconds + tenths of seconds (e.g., W072275511 = W 072°27'55.11") | degrees | 9 values
|
| dynamicMagneticVariation ← DYNAMIC_MAGNETIC_VARIATION | DynamicMagneticVariation | Magnetic variation at the waypoint location, encoded as hemisphere + degrees + tenths of degrees (e.g., W0132 = 13.2° West); used for converting between magnetic and true courses | degrees |
|
| datumCode ← DATUM_CODE | CifpHeliportDatumCode | Geodetic datum code indicating the reference datum used for the waypoint coordinates |
| |
| nameFormatIndicator ← NAME_FORMAT_INDICATOR | String | Indicates the format or type of the waypoint name/description field; null when not specified | ||
| waypointNameDescription ← WAYPOINT_NAME_DESCRIPTION | WaypointIdentifier | The full name or description of the waypoint, typically matching the waypoint identifier for terminal fixes | 9 values
| |
| fileRecordNo ← FILE_RECORD_NO | String | Sequential file record number assigned to this record within the CIFP data file, used for traceability and ordering | ||
| cycleDate ← CYCLE_DATE | CifpHeliportWaypointCycleDate | AIRAC cycle date in YYMM format indicating when this record was last updated or published (e.g., 2504 = 2025 cycle 04) |
