CEN/TC 471/WG 1 - Unmanned Aircraft Systems

This document provides means of compliance with the “Direct Remote Identification” requirements set
in Regulation (EU) 2019/945 on Unmanned Aircraft Systems.
“Direct remote identification” means a system that ensures the local broadcast of information about a
UA in operation.
More specifically, this document addresses drone’s capability to be identified during the whole duration
of the flight, in real time and with no specific connectivity or ground infrastructure link, by existing
mobile devices when within the broadcasting range. Such functionality, based on an open and
documented transmission protocol (described in this document) contributes to address security threats
and to support drones’ operators’ obligations with respect to citizens’ fundamental rights to privacy
and protection of personal data. It can be used by law enforcement people, critical infrastructure
managers, and public to get an instantaneous information on the drone flying around, providing various
information such as UA serial number, UA navigation data and operational status, UAS Operator
registration number and position as defined in the Delegated Regulation (EU) 2019/945.
Since Regulation (EU) 2019/945 requires DRI information to be broadcasted using an “open and
documented protocol”, this document does not define technological measures to protect the
confidentiality and integrity of the data broadcasted.

This document provides technical specification and verification methods to support compliance with Commission Delegated Regulation (EU) 2019/945 of 12 March 2019 on unmanned aircraft systems and on third-country operators of unmanned aircraft systems.
This part provides requirements, test methods and pass criteria for the means to terminate flight (flight termination) for unmanned aircraft systems, in particular addressing:
— safety related aspects of the architecture;
— descent performance;
— means to reduce the effects of impact on ground; and
— manufacturer’s instructions.
Even if security, including IT security, may be useful from an operational point of view, it falls outside the scope of this document.
An activation of the means to terminate the flight by a visual observer is also outside the scope of this document.
This document provides voluntary means of demonstrating compliance with the requirements laid out in Regulation (EU) 2019/945.
Additional hazards that occur from the characteristics of the payload are excluded and are, conversely, under the responsibility of the UAS manufacturer and UAS operator.
