ARINC CHARACTERISTIC 745-2-1993 PDF

Full title and description

St ARINC CHARACTERISTIC 745-2: 1993 — "Automatic Dependent Surveillance (ADS)". This ARINC characteristic defines the Automatic Dependent Surveillance Function (ADSF) and describes end-to-end ADS system functions, architecture, avionics interfaces, air/ground data links, ground network interactions and interchangeability requirements for equipment implementing ADS.

Abstract

ARINC 745-2:1993 specifies the design and functional requirements for the Automatic Dependent Surveillance (ADS) avionics function, including ADS architecture, standardized signals and interwiring, message structures and transport profiles, typical transactions and environmental categories. It includes attachments and appendices that provide connector pinouts, message parameter definitions, examples of message encoding and end-to-end application process descriptions.

General information

• Status: Current / Active (commercial listings indicate the 1993 edition as the available edition).
• Publication date: June 30, 1993 (1993-06).
• Publisher: Aeronautical Radio, Inc. (ARINC).
• ICS / categories: On-board equipment and instruments (ICS 49.090).
• Edition / version: Edition 2 (ARINC characteristic edition published 1993).
• Number of pages: 96 pages (typical commercial product listing).

Scope

This characteristic covers the ADS function from an avionics and ground application perspective: system overview and architecture, avionics form factors and interchangeability, electrical and signal standards, ADS message structures and encoding, transport profiles, application addressing and end-to-end connection models, state tables and typical transactions. It is intended to support implementers of ADS avionics and ground systems in achieving standardized, interoperable implementations.

Key topics and requirements

• ADS architecture and system overview (airborne and ground components).
• Interchangeability standards: form factor, connectors, index pin coding and standard interwiring.
• Power circuitry and grounding conventions for ADS equipment.
• Standardized digital, discrete and synchro signal definitions.
• ADS message structure, encoding samples and parameter definitions (including message bitmaps and reporting-rate definitions).
• Transport profile, application process addressing and end-to-end OSI model mapping for ADS.
• Environmental and equipment category guidance (references to avionics environmental standards).

Typical use and users

ARINC 745-2:1993 is used by avionics system architects, aircraft manufacturers, equipment suppliers, avionics integrators, ground network operators and regulators involved in surveillance, air traffic services and ADS/ADSF implementation. It supports design, integration, verification and procurement of ADS-capable avionics line-replaceable units and ground application software.
