CAA ORS9 Decision No. 1

SECONDARY SURVEILLANCE RADAR TRANSPONDERS

With regard to the requirements for secondary surveillance radar transponders, aircraft operators that are subject to UK Regulation (EU) No 965/2012 should ensure that their aircraft comply with the UK Certification Specifications for Airborne Communications, Navigation and Surveillance (CS-ACNS), Subpart D — Surveillance (SUR), and particularly:

— Section 2 ‘Mode S elementary surveillance (ELS)’;

— Section 3 ‘Mode S Enhanced Surveillance (EHS)’; and

— Section 4 ‘1090 MHz Extended Squitter ADS-B (ADSB), as applicable.

Aircraft that only require the ELS capability and were certified according to JAA TGL 13, Revision 1, or installations that comply with CS-STAN, CS-SC002b (or later versions), are considered an acceptable alternative to compliance with CS-ACNS.

Third-country-operator (TCO) aircraft that operate within the Single European Sky (SES) airspace should comply with national requirements equivalent to the requirements of CS-ACNS, Subpart D, Sections 2, 3, and 4, as applicable.
