(ARINC) and the Purpose of ARINC Reports and Specifications Aeronautical Radio, Inc. is a
6、 corporation in which the United States scheduled airlines are the principal stockholders. Other stockholders include a variety of other air transport companies, aircraft manufacturers and non-U.S. airlines. Activities of ARINC include the operation of an extensive system of domestic and overseas ae
7、ronautical land radio stations, the fulfillment of systems requirements to accomplish ground and airborne compatibility, the allocation and assignment of frequencies to meet those needs, the coordination incident to standard airborne compatibility, the allocation and assignment of frequencies to mee
8、t those needs, the coordination incident to standard airborne communications and electronics systems and the exchange of technical information. ARINC sponsors the Airlines Electronic Engineering Committee (AEEC), composed of airline technical personnel. The AEEC formulates standards for electronic e
9、quipment and systems for the airlines. The establishment of Equipment Characteristics is a principal function of this Committee. It is desirable to reference certain general ARINC Specifications or Report which are applicable to more than one type of equipment. These general Specifications and Repor
10、ts may be considered as supplementary to the Equipment Characteristics in which they are referenced. They are intended to set forth the desires of the airlines pertaining to components and general design, construction and test criteria, in order to insure satisfactory operation and the necessary int
11、erchangeability in airline service. The release of a Specification or Equipment Characteristics should not be construed to obligate ARINC or any airline insofar as the purchase of any components or equipment is concerned. An ARINC Report ( Specification or Characteristic) has a twofold purpose, whic
12、h is: (1)To indicate to the prospective manufacturers of airline electronic equipment the considered opinion of the airline technical people, coordinated on an industry basis, concerning requisites of new equipment, and (2)To channel new equipment designs in a direction which can result in the maxim
13、um possible standardization of those physical and electrical characteristics which influence interchangeability of equipment without seriously hampering engineering initiative. ii -,-,- ARINC SPECIFICATION 628, PART 3 TABLE OF CONTENTS iii ITEMSUBJECTPAGE 1.0INTRODUCTION1 1.1Purpose of This Document

27、pose 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 concen
28、trate 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 Specif
29、ication 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,
30、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
31、 a “single-electronics- box” seat design. 1.2Related Documents This document refers to Parts 1 and 4 (proposed) of ARINC Specification 628 for the definition of equipment connector pin-outs. It also relies heavily on ARINC Specifications 429 and RS 485 as defined in Appendix A for the overall data b
32、us architecture, in particular the physical and data link layers of these communications protocols. The following is a list of the documents that are pertinent to the design of equipment intended to meet this standard.

38、n the airplane. Each interface line in the shaded area of this diagram represents specific data flow between airplane systems and the IFES. The number of lines shown is not an indication of the number of physical wires (or set of wires) required to transfer the data. Separate wires will be required
39、for each type of analog signal, while the digital interfaces can be combined into a fewer number of interface wires. Attachment 1-2 is a tabular listing of the data depicted in Attachment 1-1. This table illustrates that the IFES should provide and accept data in multiple forms to accommodate variat
40、ions in different airplane models. For example, the decompression signal may be provided to the In-Flight Entertainment (IFE) equipment as an analog discrete, as a discrete on a ARINC 429 interface, or as a discrete on an RS 485 interface, depending on the airplane type. Although the IFE equipment s
41、hould support all formats, on any specific airplane model, only one format for a given discrete should be utilized. For dispatch critical and safety related discretes, such as PA keylines and decompression, individually wired discretes should be used when available. NOTE: IFE equipment suppliers sho
42、uld consult with the airframe manufacturers documentation that defines specific implementation of interfaces defined in this Specification for each of the airplane models. The following subsections describe each system function requiring data flow between the IFES and the airplane systems. Detailed
43、interfaces for each of these functions are defined in Sections 2 through 6. ARINC SPECIFICATION 628, PART 3 - Page 2 1.0 INTRODUCTION (contd) 1.3.1Crew/Passenger Address (PA) Override of Entertainment Audio entertainment via passenger headphones is interrupted during PA announcements by the flight c
44、rew. A conceptual schematic illustrating this configuration in the airplane is shown in Attachment 1-3. The Passenger Address System (PAS) sends PA Audio and PA-All Keyline to override the entertainment audio in all the seating areas connected to the PA announcement audio. The IFES sends an ENT (Ent
45、ertainment) Pause to the audio and/or video source(s) to prevent the passenger from missing audio segments and/or video scenes. Attachment 1-3 illustrates a case where a single source audio (from a microphone) PA announcement is being broadcast in all the seating areas. This would also apply to a si
46、ngle-class cabin configuration. Modern long range commercial jet transport airplanes are usually configured for multiple seating areas (first, business, economy, etc.), and may include one or more crew rest areas. For such airplanes, separate sets of PA audio and keylines will be provided to the IFE
47、S to localize PA announcement for each area. 1.3.2IFES Audio Over PA IFES audio is frequently played over the PAS in the form of boarding music from the Boarding Background Music (BGM), announcements from the Pre-Recorded Announcement Machine (PRAM), and safety demonstration or other special program
48、 audio from the Video Reproducer Unit (VRU). The IFES provides audio and associated keylines to the PAS, as is shown in Attachment 1-4. The PRAM connects to a higher priority input of the PAS, higher than the VRU and BGM. The BGM connects to the lowest priority. Thus, the PRAM or VRU will override t
49、he BGM, when the BGM is playing over the PAS. The PRAM and the VRU audio are both provided to the passengers seat, whereas the BGM audio is not. The PRAM, when in use, will activate the PA-All keyline and should cause the VRU (and ARU if desired) to pause for the duration of the PRAM announcement. The PRAM audio is always broadcast airplane wide. Any crew announcement on an airplane wide basis has a higher priority than any IFES input to PAS for PA broadcast. This means any crew announce
