ARINC 768-2

Purpose of this Document

This document defines standards for an Integrated SurveillanceSystem (ISS) that may be configured to suit a wide variety ofaircraft installations. The ISS may include components and modulesto perform multiple surveillance functions:

• Airborne Collision Avoidance System (ACAS) (also known as TCASII)

• Air Traffic Control Transponder (ATCRBS/Mode S)

• Weather Radar (WXR) / Predictive Windshear (PWS)

• Terrain Awareness and Warning System (TAWS) / ReactiveWindshear (RWS)

• Automatic Dependent Surveillance – Broadcast (ADS-B)OUT/IN

This document uses a building block approach to define four ISSconfigurations with a combination of surveillance functions. Thisdocument establishes interoperability standards for theseconfigurations. The ISS is intended for installation on commercialair transport aircraft with digital interfaces (ARINC 429 or ARINC664) with primary applicability to future aircraft and derivativesof the current generation production aircraft. This documentprovides standards for equipment form factor, signal interfaces,aircraft interwiring and connector pin allocation.

The minimum operational and performance capabilities of the ISSare further described in the related RTCA and EUROCAE MinimumOperational Performance Standards (MOPS) and Minimum AviationSystem Performance Standards (MASPS) documents for ACAS, Mode Stransponder, Weather Radar, TAWS, and ADS-BOUT/IN. Section 1.8 includes a list of referencedocuments.

The primary goal of the ISS is to simplify aircraftinstallations and reduce life cycle costs through integration, aswell as providing meaningful operational benefits. Another goal isto establish an enabling platform for future surveillancecapabilities.
