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.
