Drone fleet management specialist, Dronedesk, has announced a fully integrated Specific Operations Risk Assessment (SORA) capability, supporting both the UK SORA framework and the EASA JARUS SORA 2.5 methodology.
The new capability integrates the complete SORA calculation directly into the Dronedesk flight planning workflow and fully automates the population density assessment that drives every ground risk determination.
“By automating the calculation and building the whole assessment into planning, Dronedesk shortens the path from concept to authorised operation,” the company said. “An operator can model a route, see the population density, ground and air risk and resulting SAIL immediately, and iterate the geometry until the operation is viable, all before a single form is submitted.”
To establish the maximum population density beneath a planned operation, operators typically have to rely on manual GIS analysis, exported map data and consultancy time to determine the number of people underneath a drone. Drawing on the Copernicus Global Human Settlement Layer (GHS-POP), the Dronedesk platform evaluates population density across the realistic dispersion area of the aircraft at its declared operating altitude, using the sliding-window kernel method defined in JARUS Annex F. It fetches the population data on demand, computes density across every cell within the operational zone, and produces a per-cell audit trail that can be exported for independent review.
Because the calculation lives inside the flight planning workflow rather than in a separate tool or spreadsheet, the risk picture updates automatically whenever the operational geometry changes. From the flight geography, Dronedesk derives the contingency volume, ground risk buffer and adjacent area, determines the intrinsic Ground Risk Class, supports the selection of ground risk mitigations, classifies the Air Risk Class using live airspace data and produces the final SAIL, all within one report.
The UK SORA implementation was developed in direct consultation with the UK Civil Aviation Authority, with key methodology decisions, including the population density approach, discussed with the CAA’s SORA assessment team. Dronedesk’s population density methodology has been reviewed by the CAA’s assessment panel and acknowledged as a correct interpretation of the JARUS SORA Annex F methodology (section 3.9.1, map resolution as a function of intended operating altitude). This acknowledgment applies to the methodology; each application is still assessed on its own evidence.
“For operators, this removes a common source of uncertainty,” the company said. “Rather than defending a bespoke population density calculation from scratch, they apply a method already reviewed against the published JARUS guidance. Dronedesk reinforces this by prompting operators in-app at exactly the points where a national aviation authority will expect written justification, capturing that reasoning as the assessment is built and helping to smooth approval timelines.”
The capability has already been used in a live regulatory context, supporting a successful application to establish a UK drone test and evaluation site.
The UK SORA and EASA JARUS SORA 2.5 capabilities are live now, available as a paid add-on on Dronedesk’s Pro tier and above.
