11、dards 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
12、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 equipmen
13、t, 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 resul
14、ts in substantial benefits to the aviation industry 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 a
15、irline 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
16、 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
17、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
18、 equipment, nor does it constitute endorsement of any manufacturers 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: An Errata Report solicits any corrections to
19、the text or diagrams in this ARINC Standard. 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. -,-,- ARINC SPECIFICATION 485P1 TABLE OF CONTENTS iii 1.0 INTRODUCTION
