EVS-EN 4709-004:2026

This document will provide means of compliance to cover lighting related requirements for Parts 2 to 4 of the Annex to the Commission Delegated Regulation (EU) 2019/945 on unmanned aircraft and on third country UAS operators.
The purpose is to be able to verify that an UA is equipped with lights:
—  for the controllability of the UA (the effectiveness of those lights is not part of the lighting requirement but is covered by the controllability requirement; therefore, its verification is covered by the clause addressing the controllability requirement of EN 4709-001:2026);
—  that ensure conspicuity of the unmanned aircraft at night (see 3.45 of ISO 21384-4:2025), the design of the light shall allow a person on the ground to distinguish a UA from a manned aircraft.
This document addresses:
—  definition of types, technical requirements, and technical parameters of UA lights (e.g. position of lights for different UA categories, intensity for different operation modes);
—  definition of purpose, test procedures, requirements, and compliance rules to evaluate UA lights
