ARINC 628P3-1 PDF

Purpose of this Document

ARINC Specification 628, Part 3, consolidates and defines the various interface parameters, except for power, that may be required to support the operation of an In-Flight Entertainment System (IFES) on any airplane model. While the other parts of ARINC Specification 628 concentrate on the form, fit, and electrical compatibility of the various IFES equipment, this document concentrates on providing a clear definition of all required interface parameters between the IFES and other airplane systems.

ARINC Specification 628, Part 3 differs in scope from proposed ARINC Specification 485, which defines the control signaling between the equipment within the IFES. Part 3 also establishes a standard signaling protocol between the IFES and the airplane Passenger Service System (PSS) to manage and control the operation of the passengers reading and call lights.

Historically, different airplane models have provided a unique airplane system interface to the IFES. The lack of standardization in this area has resulted in unique IFES designs for different airplane models. Unique, proprietary PSS reading and call light protocols have been the primary obstacle to accomplishing a "single-electronicsbox" seat design.
