ARINC 424-15 Navigation System Data Base Standard

Aeronautical Radio, Inc., 2000. - 361 p.ARINC 424 is an international standard file format for aircraft navigation data maintained by Airlines Electronic Engineering Committee. The ARINC 424 specifications are not a database, but a "standard for the preparation and transmission of data for assembly of airborne navigation system data bases". ARINC 424 specifies a 132-byte fixed-length record format. Each record consists of one piece of navigation information such as an airport, heliport, runway, waypoints, navaids, airways, arrival routes, and departure routes. ARINC 424 contains several sub-specifications for different data formats. New formats have been introduced as capabilities of equipment have increased and new classes of equipment (such as GPS) have been introduced. The sub-specifications are indicated by a format number. The three sub-specifications currently in use by the NACO are ARINC 424-13, ARINC 424-15, and ARINC 424-18.
