PURPOSE

This document defines and allocates the set of minimum requirements for the end-toend operational, safety, performance and interoperability aspects for implementations of the ADS-B-NRA application. Requirements are allocated to the necessary domains of the CNS/ATM system, i.e. at aircraft and ground domain level.

These requirements can be used for approval processes including aircraft type design approval, and operational approvals for aircraft operators and Air Traffic Services Providers (ATSP).

In addition, this document also provides guidance to determine the levels of design assurance and performance that are needed for the aircraft domain systems and ground domain systems, to support the ADS-B-NRA application.

The ADS-B-NRA SPR and INTEROP standards are envisaged to be used along with SPR and INTEROP standards from other surveillance applications based on ADS-B to develop minimum standards for avionics systems. These standards will assure that all subsystems perform their intended functions adequately for ADS-B applications.
