ARINC REPORT 665-3 LOADABLE SOFTWARE STANDARDS Published: August 12, 2005ii 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
6、a privately-owned company dedicated to serving the communications needs of the air transport industry. Today, the major U.S. airlines remain the Companys principal shareholders. Other shareholders include a number of non-U.S. airlines and other aircraft operators. ARINC sponsors aviation industry co
7、mmittees 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
8、 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 aviati
9、on. 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 a
10、vionics 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 t
11、he 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
12、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 doe
13、s 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 manufacturers product designed or built to meet the ARINC Standard. In or
14、der 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 the text or diagrams in this ARINC Standard. An ARINC IA Project Initiation/Modification (APIM) form solicits any recommendatio

47、tandards for Loadable software Parts (LSPs)and software transport media parts (Media Sets). It describes the common principles and rules to be applied to any part of a data load system, to insure compatibility and inter-operability. It includes part numbering, content, labeling and formatting of an
48、LSP, and a Media Set containing LSPs. Loadable Software Airplane Parts (LSAP) is a subset of the LSP class of parts. All requirements for LSPs in this document also apply to LSAPs. Uniform software LSP and Media Set formats enable suppliers to employ common (standardized) loadable software processes
49、, procedures, and support tools. It is intended that software loaders, tools, processes and aircraft systems reference this standard for definition of loadable software part and software transport media content and format. This should be independent of any specific data load system, production process, or aircraft system that uses the LSP. 1.2 Applicability This standard is applicable to all loadabl
