means an operation during which an unmanned aircraft operates without the remote pilot being able to intervene;
- beyond visual line of sight operation
(‘BVLOS’) means a type of UAS operation which is not conducted in VLOS;
- contingency area
means the projection of the contingency volume on the surface of the earth;
- contingency volume
means the volume of airspace outside the flight geography where contingency procedures described in point (6)(d) of Appendix 5 to the Annex are applied;
- control and monitoring unit (CMU)
means the equipment to control and monitor unmanned aircraft remotely as defined in point (32) of Article 3 of Regulation (EU) 2018/1139;
- controlled ground area
means the ground area where the UAS is operated and within which the UAS operator can ensure that only involved persons are present;
- dangerous goods
means articles or substances, which are capable of posing a hazard to health, safety, property or the environment in the case of an incident or accident, that the unmanned aircraft is carrying as its payload, including in particular:
- direct remote identification
means a system that ensures the local broadcast of information about a unmanned aircraft in operation, including the marking of the unmanned aircraft, so that this information can be obtained without physical access to the unmanned aircraft;
- flight geography
means the volume(s) of airspace defined spatially and temporally in which the UAS operator plans to conduct the operation under normal procedures described in point (6)(c) of Appendix 5 to the Annex;
- flight geography area
means the projection of the flight geography on the surface of the earth;
- follow-me mode
means a mode of operation of a UAS where the unmanned aircraft constantly follows the remote pilot within a predetermined radius;
- geo-awareness
means a function that, based on the data provided by Member States, detects a potential breach of airspace limitations and alerts the remote pilots so that they can take immediate and effective action to prevent that breach;
- light UAS operator certificate
(‘LUC’) means a certificate issued to a UAS operator by a competent authority as set out in part C of the Annex;
- making available on the market
means any supply of a product for distribution, consumption or use on the Union market in the course of a commercial activity, whether in exchange of payment or free of charge;
- maximum take-off mass
(‘MTOM’) means the maximum Unmanned Aircraft mass, including payload and fuel, as defined by the manufacturer or the builder, at which the Unmanned Aircraft can be operated;
- model aircraft club or association
means an organisation legally established in a Member State for the purpose of conducting leisure flights, air displays, sporting activities or competition activities using UAS;
- night
means the hours between the end of evening civil twilight and the beginning of morning civil twilight as defined in Implementing Regulation (EU) No 923/2012;
- payload
means instrument, mechanism, equipment, part, apparatus, appurtenance, or accessory, including communications equipment, that is installed in or attached to the aircraft and is not used or intended to be used in operating or controlling an aircraft in flight, and is not part of an airframe, engine, or propeller;
- placing on the market
means the first making available of a product on the Union market;
- privately built UAS
means a UAS assembled or manufactured for the builder's own use, not including UAS assembled from sets of parts placed on the market as a single ready-to-assemble kit;
- robustness
means the property of mitigation measures resulting from combining the safety gain provided by the mitigation measures and the level of assurance and integrity that the safety gain has been achieved;
- standard scenario
means a type of UAS operation in the ‘specific’ category, as defined in Appendix 1 of the Annex, for which a precise list of mitigating measures has been identified in such a way that the competent authority can be satisfied with declarations in which operators declare that they will apply the mitigating measures when executing this type of operation;
- uninvolved persons
means persons who are not participating in the UAS operation or who are not aware of the instructions and safety precautions given by the UAS operator;
- unmanned aircraft observer
means a person, positioned alongside the remote pilot, who, by unaided visual observation of the unmanned aircraft, assists the remote pilot in keeping the unmanned aircraft in VLOS and safely conducting the flight;
- unmanned aircraft system (UAS)
means an unmanned aircraft, as defined in Article 3(30) of Regulation (EU) 2018/1139, and its control and monitoring unit;
- unmanned aircraft system operator
(‘UAS operator’) means any legal or natural person operating or intending to operate one or more UAS;
- unmanned sailplane
means an unmanned aircraft that is supported in flight by the dynamic reaction of the air against its fixed lifting surfaces, the free flight of which does not depend on an engine.
- visual line of sight operation
(‘VLOS’) means a type of UAS operation in which, the remote pilot is able to maintain continuous unaided visual contact with the unmanned aircraft, allowing the remote pilot to control the flight path of the unmanned aircraft in relation to other aircraft, people and obstacles for the purpose of avoiding collisions;
