RTCA published RTCA DO-303 - Safety, Performance and Interoperability Requirements Document for the ADS-B Non-Radar-Airspace (NRA) Application document.
This document addresses the operational concept and minimum requirements for the use of automatic dependent surveillance - broadcast (ADS-B) surveillance for air traffic services (ATS) in non-radar areas (ADS-B-NRA).
The document's annexes feature:
- The operational services and environment definition (OSED).
- A comparative operational performance assessment (OPA).
- An operational safety assessment (OHA).
- A summary of a published comparative risk assessment.
The results of these assessments were compiled into Section 3 of the main body, which specifies the minimum operational safety and performance requirements (SPR).
Interoperability requirements specifying the needed transfer of data between transmitting aircraft and ground domains is provided in Section 4 (INTEROP).
This INTEROP specification is presented at a link-neutral (i.e. MASPS) level. Annex H provides traceability of Section 4 to specific 1090MHz extended squitter interoperability requirements.
It was developed jointly with European Organisation for Civil Aviation Equipment (EUROCAE).
