Purpose of ARINC Specification 429

ARINC Specification 429 defines the air transport industry’s standard for the transfer of digital data between avionics systems elements. Adherence to these standards is desired for all avionics inter-system and intra-system communication, particularly when used with the related ARINC Characteristics.

Relationship to Other Documents

The material in this Specification is intended to complement other ARINC Characteristics, Specifications, and Reports written for avionics. It is also the intent of this document to encourage the use of any standards of good practice, that have been developed by the government, the military, and other industry groups, provided they are applicable to airline electronic equipment.

When ARINC 429 was originally developed, all ARINC 429 discrete words were defined in this document. However, with the proliferation of ARINC 429 discrete words, the associated ARINC Characteristic and Specification have been maintaining their own discrete word definitions.

Tables 1 and 2 to this document have been developed to aid the reader in reviewing the discrete words. Table 1 is sorted by Equipment Identifier and Table 2 is sorted by octal label number. These tables summarize all the discrete words and refers the reader to the location where the bit definition of that discrete word is maintained.

There are numerous cases where a discrete label has been assigned but no source documentation has been identified for the bit description. If this is the case, the source location column will be blank.
