Purpose of this Document
ARINC Specification 628 defines general system architecturalphilosophy and specific design guidance for the design andinterface of various cabin related equipment. Compliance with ARINCSpecification 628 allows each respective ARINC equipment standardto interoperate when integrated with other relevant n equipment.System performance parameters are described herein for connectors,electrical interfaces, operational mode control/protocols, BITEreporting, reliability, environmental conditions and software dataloading.
Cabin subsystems are becoming more sophisticated and complex.This is due primarily to the passenger entertainment and serviceimprovements to enhance passenger comfort. Almost unlimitedselections of audio and video programming are becoming available tothe passengers. State-of-the-art video entertainment subsystemswith a capability for video games and catalog viewing are beingprovided on a personalized basis. Passengers can communicate almostanywhere in the world via a telephone at their seat. Office typecomputing system and peripherals are also finding theirapplications in the cabin to facilitate data handling andmanagement, and to link cabin data communication to the ground.
Standardization will enable the airlines to reap the benefits ofthese improvements. These benefits are achieved through greaterairline freedom of choice, unit price reduction through increasedvolume, interchangeable spares and greater availability of spares,more upgradeable options and creating more sub-markets forintegrators and software/hardware suppliers.
Each subsystem may embody design features that are airlineunique. Due to the unique nature of some equipment, only interfacesare standardized. Some functionalities are recommended as thedesign guidelines only.
Cabin subsystems should be managed, controlled and maintainedsystematically. Integration of management and control databuses/protocols is desirable to prevent proliferations of controlpoints in the cabin. Centralizing management and controls of thedifferent cabin subsystems facilitates operation, maintenance andtroubleshooting, significantly.
