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 a privately-owned company dedicated to serving the communications needs of the air transport industry. Today, the major U.S. airlines remain the Company’s principal shareholders. Other shareholders include a number of non-U.S. airlines and other aircraft operators. ARINC sponsors aviation industry committees 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 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 aviation. 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 avionics 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 the 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 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 does 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 manufacturer’s product designed or built to meet the ARINC Standard. In order 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 recommendations for addition of substantive material to this volume which would be the subject of a new Supplement. ii ARINC SPECIFICATION 429 TABLE OF CONTENTS 1.0 1.1 1.1.1 1.2 INTRODUCTION ......................................................................................................... 1 Purpose of ARINC Specification 429 ........................................................................... 1 Relationship to Other Documents ........................................................................... 1 Organization of ARINC Specification 429 .................................................................... 1 Table 1 List of Discrete Labels by Equipment Identifier ............................................................ 2 Table 2 List of Discrete Labels by Octal Number.................................................................... 11 DATA STANDARDS ........................................................................................................... 20 ARINC IA Project Initiation/Modification (APIM) Guidelines for Submittal ...............................End ARINC Standard – Errata Report............................................................................................End iii ARINC SPECIFICATION 429 PART 2 – Page 1 1.0 INTRODUCTION 1.1 Purpose of ARINC Specification 429 ARINC Specification 429 defines the air transport industry’s standard for the transfer of digital data between avionics systems elements. Adherence to these standards is desired for all inter-system communications in which the system line replaceable units are defined as “unit interchangeable” in the relevant ARINC characteristics. Their use for intra-system interchangeability is not essential, although it is desired. 1.1.1 Relationship to Other Documents The material in this Specification is intended to complement other ARINC Characteristics, Specifications and Reports written for avionics. It is also the intent of this document to encourage the use of any standards of good practice, that have been developed by the government, the military and other industry groups, provided they are applicable to airline electronic equipment. When ARINC 429 was originally developed, all ARINC 429 discrete words were defined in this document. However, with the proliferation of ARINC 429 discrete words, the associated ARINC Characteristic and Specification have been maintaining their own discrete word definitions. Tables 1 and 2 to this document have been developed to aid the reader in reviewing the discrete words. Table 1 is sorted by Equipment Identifier and Table 2 is sorted by octal label number. These tables summarize all the discrete words, and refers the reader to the location where the bit definition of that discrete word is maintained. There are numerous cases where a discrete label has been assigned but no source documentation has been identified for the bit description. If this is the case, the source location column will be blank. 1.2 Organization of ARINC Specification 429 ARINC Specification 429 was originally published in a single volume until version 14 (429-14) was released. The size of the document and the need for improved organization dictated the division of the document into three parts. Those three parts include: Part 1, “Functional Description, Electrical Interface, Label Assignments and Word Formats Part 2, “Discrete Word Data Formats Part 3, “File Data Transfer Techniques” Part 1 provides the basic description of the functions and the supporting physical and electrical interfaces for the data transfer system. Data word formats, standard label and address assignments, and application examples are defined. Part 2 lists discrete word bit assignments in label order. Part 3 describes protocols and message definitions for data transferred in large blocks and file format. For convenience of the user, the section and attachment numbering has been retained for the material moved from the original Specification to Part 3. Updates to each part of future releases of ARINC 429 will be independent of the other parts to accommodate timely revisions as industry needs dictate. The dash numbers for each new Part will not be synchronized with the other Parts as time passes. Users of ARINC Specification 429 should ensure that the latest version of each Part is used when designing or procuring equipment ARINC SPECIFICATION 429 PART 2 – Page 2 DATA STANDARDS Table 1 List of Discrete Labels by Equipment Identifier Code No. (Octal) 111 266 270 272 273 274 275 300 301 302 303 304 305 306 307 207 270 271 272 275 276 301 302 303 354 357 272 273 274 275 350 270 277 350 270 271 272 270 271 350 351 075 076 077 242 244 246 247 274 124 270 Eqpt.

This condition shall be reset only by power on initialization. 21 Align Fault Failed the IRU operating software ALIGN criterion, but neither power on nor continuous BitE show any faults. 22 No IRS Initialization No input or an incorrect input has been received from the IRMP or FMCs. 23 Excessive Motion Error Non-zero ground speed during the ALIGN mode. 24 ADC/IRU Fault ADC inflight fault, but no power-on BitE information available prior to flight. 25 No VOR/DME #1 Input Align status is represented by a series of descending digits, each indicating a 26 Align Status successive state of alignment.

[2] Bit 13 “1” condition indicates that AHRS is in the “Normal” mode as described in Section 1.2.1 of ARINC Characteristic 705. A “0” condition indicates that the AHRS is in the reversionary “basic mode.” [3] Bit 14 “1” condition indicates that AHRS is in the “Magnetic Heading” mode. A “0” condition indicates the AHRS is in the reversionary “DG” mode. See Section 1.2.2 of ARINC Characteristic 705 for description of modes of heading operation.

ARINC Industry Activities Projects and Work Program A project is established in order to accomplish a technical task approved by one or more of the committees (AEEC, AMC, FSEMC) Projects generally but not exclusively result in a new ARINC standard or modify an existing ARINC standard. All projects are typically approved on a calendar year basis. Any project extending beyond a single year will be reviewed annually before being reauthorized. The work program of Industry Activities (IA) consists of all projects authorized by AEEC, AMC, or FSEMC (The Committees) for the current calendar year. The Committees establish a project after consideration of an ARINC Project Initiation/Modification (APIM) request. This document includes a template which has provisions for all of the information required by The Committees to determine the relative priority of the project in relation to the entire work program. All recommendations to the committees to establish or reauthorize a project, whether originated by an airline or from the industry, should be prepared using the APIM template. Any field that cannot be filled in by the originator may be left blank for subsequent action. 2. Normal APIM Evaluation Process Initiation of an APIM All proposed projects must be formally initiated by filling in the APIM template. An APIM may be initiated by anyone in the airline community, e.g., airline, vendor, committee staff. Staff Support All proposed APIMs will be processed by committee staff. Each proposal will be numbered, logged, and evaluated for completeness. Proposals may be edited to present a style consistent with the committee evaluation process. For example, narrative sentences may be changed to bullet items, etc. When an APIM is complete, it will be forwarded to the appropriate Committee for evaluation. The committee staff will track all ongoing projects and prepare annual reports on progress. Committee Evaluation and Acceptance or Rejection The annual work program for each Committee is normally established at its annual meeting. Additional work tasks may be evaluated at other meetings held during the year. Each committee (i.e., AMC, AEEC, FSEMC) has its own schedule of annual and interim meetings. 15_APIM-VerJ.doc Page 1 ARINC Project Initiation/Modification 12/22/04 The committee staff will endeavor to process APIMs and present them to the appropriate Committee at its next available meeting. The Committee will then evaluate the proposal. Evaluation criteria will include: • Airline support – number and strength of airline support for the project, including whether or not an airline chairman has been identified • Issues – what technical, programmatic, or competitive issues are addressed by the project, what problem will be solved • Schedule – what regulatory, aircraft development or modification, airline equipment upgrade, or other projected events drive the urgency for this project Accepted proposals will be assigned to a subcommittee for action with one of two priorities: • High Priority – technical solution needed as rapidly as possible • Routine Priority – technical solution to proceed at a normal pace Proposals may have designated coordination with other groups. This means that the final work must be coordinated with the designated group(s) prior to submittal for adoption consideration. Proposals that are not accepted may be classified as follows: • Deferred for later consideration - the project is not deemed of sufficient urgency to be placed on the current calendar of activities but will be reconsidered at a later date • Deferred to a subcommittee for refinement – the subcommittee will be requested to, for example, gain stronger airline support or resolve architectural issues • Rejected – the proposal is not seen as being appropriate, e.g., out of scope of the committee 3. APIM Template The following is an annotated outline for the APIM. Proposal initiators are requested to fill in all fields as completely as possible, replacing the italicized explanations in each section with information as available. Fields that cannot be completed may be left blank. When using the Word file version of the following template, update the header and footer to identify the project. 15_APIM-VerJ.doc Page 2 ARINC Project Initiation/Modification 12/22/04 ARINC IA Project Initiation/Modification (APIM) Name of proposed project APIM #: _____ Name for proposed project. Suggested Subcommittee assignment Identify an existing group that has the expertise to successfully complete the project. If no such group is known to exist, a recommendation to form a new group may be made. Project Scope Describe the scope of the project clearly and concisely. The scope should describe “what” will be done, i.e., the technical boundaries of the project. Example: “This project will standardize a protocol for the control of printers. The protocol will be independent of the underlying data stream or page description language but will be usable by all classes of printers.” Project Benefit Describe the purpose and benefit of the project. This section should describe “why” the project should be done. Describe how the new standard will improve competition among vendors, giving airlines freedom of choice. This section provides justification for the allocation of both IA and airline resources. Example: “Currently each class of printers implements its own proprietary protocol for the transfer of a print job. In order to provide access to the cockpit printer from several different avionics sources, a single protocol is needed. The protocol will permit automatic determination of printer type and configuration to provide for growth and product differentiation.” Airlines supporting effort Name, airline, and contact information for proposed chairman, lead airline, list of airlines expressing interest in working on the project (supporting airlines), and list of airlines expressing interest but unable to support (sponsoring airlines). It is important for airline support to be gained prior to submittal. Other organizations, such as airframe manufacturers, avionics vendors, etc. supporting the effort should also be listed. Issues to be worked Describe the major issues to be addressed by the proposed ARINC standard. Recommended Coordination with other groups Draft documents may have impact on the work of groups other than the originating group. The APIM writer or, subsequently, The Committee may identify other groups which must be given the opportunity to review and comment upon mature draft documents. 15_APIM-VerJ.doc Page 3 ARINC Project Initiation/Modification 12/22/04 Projects/programs supported by work If the timetable for this work is driven by a new airplane type, major avionics overhaul, regulatory mandate, etc., that information should be placed in this section. This information is a key factor in assessing the priority of this proposed task against all other tasks competing for subcommittee meeting time and other resources. Timetable for projects/programs Identify when the new ARINC standard is needed (month/year). Documents to be produced and date of expected result The name and number (if already assigned) of the proposed ARINC standard to be either newly produced or modified. Comments Anything else deemed useful to the committees for prioritization of this work. Meetings The following table identifies the number of meetings and proposed meeting days needed to produce the documents described above.
