Description / Abstract:
Purpose of this Document
This document defines standards for an Integrated Surveillance
System (ISS) that may be configured to suit a wide variety of
aircraft installations. The ISS may include components and modules
to perform multiple surveillance functions:
• Airborne Collision Avoidance System (ACAS) (also known as TCAS
II)
• Air Traffic Control Transponder (ATCRBS/Mode S)
• Weather Radar (WXR) / Predictive Windshear (PWS)
• Terrain Awareness and Warning System (TAWS) / Reactive
Windshear (RWS)
• Automatic Dependent Surveillance – Broadcast (ADS-B)
OUT/IN
This document uses a building block approach to define four ISS
configurations with a combination of surveillance functions. This
document establishes interoperability standards for these
configurations. The ISS is intended for installation on commercial
air transport aircraft with digital interfaces (ARINC 429 or ARINC
664) with primary applicability to future aircraft and derivatives
of the current generation production aircraft. This document
provides standards for equipment form factor, signal interfaces,
aircraft interwiring and connector pin allocation.
The minimum operational and performance capabilities of the ISS
are further described in the related RTCA and EUROCAE Minimum
Operational Performance Standards (MOPS) and Minimum Aviation
System Performance Standards (MASPS) documents for ACAS, Mode S
transponder, Weather Radar, TAWS, and ADS-B
OUT/IN. Section 1.8 includes a list of reference
documents.
The primary goal of the ISS is to simplify aircraft
installations and reduce life cycle costs through integration, as
well as providing meaningful operational benefits. Another goal is
to establish an enabling platform for future surveillance
capabilities.
