AMC1 SERA.6005(c) Requirements for communications, SSR transponder and electronic conspicuity in U-space airspace

MEANS OF TRANSMISSION OF INFORMATION AND INFORMATION TO BE TRANSMITTED

(a) Manned aircraft should transmit information through one or more of the following means to continuously make themselves electronically conspicuous to U-space service providers:

(1) A certified ADS-B Out system compliant with ICAO Annex 10 Volume IV Chapter 5
(Mode-S Extended Squitter).

(2) A certified ADS-B Out system compliant with ICAO Annex 10 Volume III Chapter 12 (Universal Access Transceiver) 12 months after its implementation and deployment for that purpose in all Member States.

(3) A system that transmits the information specified in Appendix 1 to this AMC using:

(i) a short-range device (SRD) 860 frequency band, and the information is transmitted in compliance with the format as documented in technical specification
ADS-L 4 SRD-860;

(ii) standardised mobile telecommunication network services coordinated for aerial use in the relevant decisions of the Electronic Communication Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT), and the information is transmitted in compliance with the format as documented in technical specification ADS-L 4 MOBILE. The aircraft operator using application-based service should ensure that all other applications or functions that might run in the background are switched off or made inactive to limit in-flight transmissions to only those necessary to minimise interference through unpredictable data upload.

This option becomes applicable 6 months after the publication of the technical specification ADS-L 4 MOBILE.

The systems used for transmission in accordance with points (3)(i) and (ii) should bear an appropriate CE marking, and be either installed on the aircraft with the installation approved by the competent authority or carried on board the aircraft as non-installed equipment.

(b) The information specified in Appendix 1 to this AMC, and which is transmitted through a system referred to in points (3)(i) and (ii), shall be transmitted in a machine-readable format accessible to U-space service providers without any restrictions.
