Everything you need
for the Specific category

MissionDesk guides you step by step through the full SORA assessment, mission briefing, and pre-flight preparation – from iGRC to final SAIL classification and PDF report.

iGRC Calculation

Automatic calculation of the intrinsic Ground Risk Class based on UAS dimensions, operating speed, and population density, in accordance with SORA v2.5 Table 2.

SORA Step 2
ARC Determination

Air Risk Class is determined from airspace class and altitude. Full support for U-space airspace (EU 2021/664), including automatic ARC mitigation via U-space services.

SORA Step 5
OSO Scoring

Interactive assessment of all 24 Operational Safety Objectives. Each OSO is linked to its robustness criterion (M/D/O) and adequacy level (Low / Medium / High / Very High).

SORA Step 8
Containment

Assessment of the operational volume, contingency zone, and ground risk buffer. Determines GRC mitigation credit based on the selected containment strategy.

SORA Step 3
Mission Import

Import mission files directly from ArduPilot Mission Planner or Litchi. MissionDesk uses the waypoint data as the foundation for the full risk assessment and briefing.

Import
Pre-flight Briefing

Generates a complete pre-flight briefing including current METAR / TAF weather, NOTAMs, and radio frequencies for aerodromes along the planned route.

Briefing
SAIL & Category

Automatic SAIL determination from GRC and ARC. Classifies the operation as Open, Specific (PDRA / STS / ConOps), or Certified category per EU 2019/947.

SORA Step 9
PDF Report

Generates a structured PDF report covering the complete assessment and briefing. Ready to attach to an authorisation application submitted to your national CAA.
