GM1 Annex IV UAS flight authorisation request referred to in Article 6(4)

CONSTITUENTS

(a)The table below includes clarifications on the information contained in Annex IV to Regulation (EU) 2021/664.

Information typePossible examples
1Unique serial number of the unmanned aircraft or the remote identification add-onANSI/CTA-2063-A specified in Regulation (EU) 2019/947
2aMode of operationVLOS, BVLOS
2bSAIL of the operationProvision for further potential check
3Type of flight (special operations)Article 4(1) of Regulation (EU) No 923/2012 (SERA) (a) police and customs missions; (b) traffic surveillance and pursuit missions; (c) environmental control missions conducted by, or on behalf of, public authorities; (d) search and rescue; (e) medical flights; (f) evacuations; (g) firefighting; (h) exemptions required to ensure the security of flights by heads of State, ministers and comparable State functionaries.
4aCategory of UAS operation‘open’, ‘specific’, ‘certified’
4bUAS aircraft classC0, C1, C2, C3, C4, C5, C6, < 1 m, < 3 m, < 8 m, ≥ 8 m, Others: can be linked to model aircraft or similar special cases.
4cUAS type certificateA UAS subject to certification should comply with the applicable requirements set out in Regulations (EU) No 748/2012, (EU) 2015/640 and (EU) No 1321/2014.
54D trajectoryStandardisation of acceptable formats for the storage and distribution of common data models (DTM/DSM/DEM) together with their metadata and timeliness.
6Identification technologyThe technology used for the remote identification (e.g. GNSS-LTE, ADS-B Out)
7Expected connectivity methodsTo be expressed in terms of a standard, when available.
8EnduranceMaximum endurance (in minutes). Endurance under nominal conditions.
9Applicable emergency procedureEmergency procedures will be supplied in a form agreed with the USSP. The information should allow the service provider to anticipate the behaviour of the aircraft in case the link is lost. The emergency procedures contain the planned manoeuvres, change of routes, automatic landing site, etc., which could be performed in case of contingency/emergency, and to be checked free of intersection by the USSP.
10aRegistration number of the UAS operatorAMC1 to Article 14(6) of Regulation (EU) 2019/947
10bRegistration number of the unmanned aircraftInformally the ‘tail number’ — for certified aircraft

(b)The 4D trajectory describes a series of one or more 4D volumes, each with entry and exit times. The UAS operator submits this series of volumes, committing to remain within them. The volumes may overlap to express uncertainty in any dimension (for example, time). The conflict detection process is simply the identification of overlapping 4D volumes.

(c)The navigation performance is reflected in the dimensions of the volume. A situation leading to the use of a less precise measurement system (for example, the use of barometric height rather than GNSS) should be reflected in a revision of the dimensions to accommodate the corresponding uncertainty (± 30 m rather than ± 30 cm).
