FOREWORD
Aeronautical Radio, Inc., the AEEC, and ARINC Standards
ARINC organizes aviation industry committees and participates in related industry
activities that benefit aviation at large by providing technical leadership and guidance.
These activities directly support aviation industry goals: promote safety, efficiency,
regularity, and cost-effectiveness in aircraft operations.
ARINC Industry Activities organizes and provides the secretariat for international aviation
organizations (AEEC, AMC, FSEMC) which coordinate the work of aviation industry
technical professionals and lead the development of technical standards for airborne
electronic equipment, aircraft maintenance equipment and practices and flight simulator
equipment and used in commercial, military, and business aviation. The AEEC, AMC, and
FSEMC develop consensus-based, voluntary standards that are published by ARINC and
are known as ARINC Standards. The use of ARINC Standards results in substantial
technical and economic benefit to the aviation industry.
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 organization 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
forms are included in the back of this document:
An Errata Report solicits any corrections to existing text or diagrams that may be included
in a future Supplement to this ARINC Standard.
An ARINC IA Project Initiation/Modification (APIM) form solicits any proposals for the
addition of technical material to this ARINC Standard.
