ARINC429总线协议又称ARINC是美国航空电子工程委员会(Airlines Electronic Engineering Committee)于1977年7月提出的,并于同年节月发表并获得批准使用。它的全称是数字式 信息传输系统DITS。协议标准规定了航空电子设备及有关系统间的数字信息传输要求。ARINC429广泛应用在先进的民航客机中,如B-737、B757、B-767,俄制军用飞机也选用了类似的技术。我们与之对应的标准是HB6096-SZ-01。

FOREWORD
Aeronautical Radio, Inc., the AEEC, and ARINC Standards
Aeronautical Radio, Inc. (ARINC) was incorporated in 1929 by four fledgling airlines in the United
States as a privately-owned company dedicated to serving the communications needs of the air transport
industry. Today, the major U.S. airlines remain the Company’s principal shareholders. Other
shareholders include a number of non-U.S. airlines and other aircraft operators.
ARINC sponsors aviation industry committees and participates in related industry activities that benefit
aviation at large by providing technical leadership and guidance and frequency management. These
activities directly support airline goals: promote safety, efficiency, regularity, and cost-effectiveness in
aircraft operations.
The Airlines Electronic Engineering Committee (AEEC) is an international body of airline technical
professionals that leads the development of technical standards for airborne electronic equipment-
including avionics and in-flight entertainment equipment-used in commercial, military, and business
aviation. The AEEC establishes consensus-based, voluntary form, fit, function, and interface standards
that are published by ARINC and are known as ARINC Standards. The use of ARINC Standards results
in substantial benefits to airlines by allowing avionics interchangeability and commonality and reducing
avionics cost by promoting competition.
There are three classes of ARINC Standards:
a)
ARINC Characteristics—Define the form, fit, function, and interfaces of avionics and other
airline electronic equipment. ARINC Characteristics indicate to prospective manufacturers of
airline electronic equipment the considered and coordinated opinion of the airline technical
community concerning the requisites of new equipment including standardized physical and
electrical characteristics to foster interchangeability and competition.
b)
ARINC Specifications—-Are principally used to define either the physical packaging or
mounting of avionics equipment, data communication standards, or a high-level computer
language.
c)
ARINC Reports— -Provide guidelines or general information found by the airlines to be
good practices, often related to avionics maintenance and support.
The release of an ARINC Standard does not obligate any airline or ARINC to purchase equipment so
described, nor does it establish or indicate recognition or the existence of an operational requirement for
such equipment, nor does it constitute endorsement of any manufacturer’s product designed or built to
meet the ARINC Standard.
In order to facilitate the continuous product improvement of this ARINC Standard, two items are included
in the back of this volume:
a)
An Errata Report solicits any corrections to the text or diagrams in this ARINC Standard.
b)
An ARINC IA Project Initiation/Modification (APIM) form solicits any recommendations for
addition of substantive material to this volume which would be the subject of a new
Supplement.
