PURPOSE OF THIS DOCUMENT

This document defines and allocates the set of minimum requirements for the end-toend operational, safety, performance and interoperability aspects for implementations of the ATSA-ITP application. Allocation of these requirements is done by this SPR/INTEROP 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, aircraft operator operational approval, and Air Traffic Services (ATS) provider operational approval.

In addition, this document also provides guidance to determine the levels of design assurance and performance that are needed for each element (aircraft, operator, and ANSP - Air Navigation Service Provider) to support the ATSA-ITP application.

The ATSA-ITP SPR and INTEROP are also envisaged to be used along with those from other surveillance applications, based on Automatic Dependent Surveillance Broadcast (ADS-B), to develop minimum standards for avionic systems to assure that all subsystems perform their intended functions adequately for these applications.
