6、1929 by four fledgling airlines in the UnitedStates as a privately-owned company dedicated to serving the communications needs of the air transportindustry. Today, the major U.S. airlines remain the Companys principal shareholders. Othershareholders include a number of non-U.S. airlines and other ai

7、rcraft operators.ARINC sponsors aviation industry committees and participates in related industry activities that benefitaviation at large by providing technical leadership and guidance and frequency management. Theseactivities directly support airline goals: promote safety, efficiency, regularity,

8、and cost-effectiveness inaircraft operations.The Airlines Electronic Engineering Committee (AEEC) is an international body of airline technicalprofessionals that leads the development of technical standards for airborne electronic equipment-including avionics and in-flight entertainment equipment-us

9、ed in commercial, military, and businessaviation. The AEEC establishes consensus-based, voluntary form, fit, function, and interface standardsthat are published by ARINC and are known as ARINC Standards. The use of ARINC Standards resultsin substantial benefits to airlines by allowing avionics inter

10、changeability and commonality and reducingavionics cost by promoting competition.There are three classes of ARINC Standards:a) ARINC CharacteristicsDefine the form, fit, function, and interfaces of avionics and otherairline electronic equipment. ARINC Characteristics indicate to prospective manufact

11、urers ofairline electronic equipment the considered and coordinated opinion of the airline technicalcommunity concerning the requisites of new equipment including standardized physical andelectrical characteristics to foster interchangeability and competition.b) ARINC Specifications-Are principally

12、used to define either the physical packaging ormounting of avionics equipment, data communication standards, or a high-level computerlanguage.c) ARINC Reports -Provide guidelines or general information found by the airlines to begood practices, often related to avionics maintenance and support.The r

Itincorporates changes to MIL-C-81659 that have takenplace since ARINC Specification 404A was publ

29、ished in1974. These changes have not affected the form, fit orfunction of the connectors. In addition, new avionicsinstallations on commercial aircraft are requiring the useof connectors that provide EMI protection. These EMIrequirements have been added to this Specification.ARINC Specification 404B

30、 contains provisions for theconnectors along with Appendices A and B that define theconnector insert arrangements and the connector keyinglayouts, respectively. In addition, there is a series of 12connector drawings defining the dimensionalconfiguration of the four basic shell sizes for plugs,recept

31、acles and plugs with EMI capability. ThisSpecification improves definition of the connector portionof ARINC Specification 404A.1.2 ClassificationConnectors covered by this standard should have wiresupport grommets.1.2.1 Temperature RatingThe connector should be operable between thetemperature ranges

32、 of -55C to +125C.1.3 Part NumberThe connector part number should consist of a series ofalphanumeric characters.1.4 ContentsThe contacts should be rear release from the connector,unless otherwise specified (see Section 3.1).1.5 Contact Insert ArrangementsContact insert arrangements should be as spec
