2.6.2. OPERATIONAL APPROVAL OF ADS-B OUT
AIRBUS obtained the EASA airworthiness certification for ADS-B NRA on the A320 family aircraft, the A330/A340 family aircraft and the A380 aircraft. The AFM states the ADS-B NRA capability. At the time of writing the brochure, four circulars on ADS-B NRA airworthiness approval were identified (see References):
-
The European AMC 20-24 – Certification Considerations for the Enhanced ATS in Non-Radar Areas using ADS-B Surveillance (ADS-B-NRA) Application
-
The Australian AC 21-45 – Airworthiness Approval of Airborne Automatic Dependent Surveillance Broadcast Equipment
-
The Canadian AC 700-009 – Automatic Dependent Surveillance - Broadcast
-
The US NPRM Automatic Dependent Surveillance—Broadcast (ADS–B) Out Performance Requirements to Support Air Traffic Control (ATC) Service.
The FAA expects to release the final rule based on its NRPM by the end of 2009. It encompasses demanding ADS-B performance requirements for the 2020 milestone of the Surveillance and Broadcast Services program (refer to Appendix A – Worldwide ADS-B implementation). The NPRM aims at ADS-B RAD services. At the time of writing the brochure, a lot of discussions about the NPRM were in progress. Updated information will be provided in a timely manner.
Operators must obtain an operational approval before starting ADS-B NRA operations. Eurocontrol outlines some guidelines for the operational approval process at
http://www.eurocontrol.int/cascade/public/standard_page/guidelines.html
The operational approval covers the following items (but not limited to):
- Operations manuals: AFM, FCOM and MEL should be updated to reflect the installation of ADS-B components.
- Flight crew training: flight crews should be familiar with ADS-B in terms of procedures, phraseology, operating principles and operational requirements
(e.g. flight number format).
- Maintenance: regular checks of ADS-B equipment should be performed including the verification of the 24-bit address.
Refer to one of the appropriate circulars quoted above for details. In addition, operators should use the ADS-B OUT Capability Declaration referenced in their AFM to support their operational approval with authorities. Please contact your Customer Service Director (CSD) to get a copy of this document.
