ED Decision 2022/008/R

CS-ACNS Issue 4

The objectives of this Decision are:

• to maintain a high level of safety;
• to ensure interoperability compliance of aircraft with the requirements of Commission Implementing Regulation (EU) No 1207/2011 laying down requirements for the performance and the interoperability of surveillance for the single European sky (the ‘Surveillance Performance and Interoperability (SPI) Regulation’); and
• to provide consolidated acceptable means of compliance (AMC) for aircraft-manufacturing industries and aircraft modification industries.

This Decision amends the Certification Specifications and Acceptable Means of Compliance for Airborne Communications, Navigation and Surveillance (CS-ACNS) applicable to all aircraft, to address a number of issues, reported by applicants, in demonstrating compliance with CS-ACNS paragraphs.

The amendments are expected to:

• maintain a high level of safety;
• ensure aircraft interoperability;
• reduce the regulatory burden of compliance with the SPI Regulation; and
• increase efficiency in implementing CS-ACNS.
