Step 1 – Detailed Operational Information (DOI)
// SORA 2.5 STEP #1 · FORMERLY "ConOps" · BASED ON ANNEX A TEMPLATE
In SORA 2.5, the concept of ConOps has been replaced by Detailed Operational Information (DOI).
DOI is the structured information baseline that underpins all subsequent risk assessment steps (Annex A, ED Decision 2025/018/R).
Fill in the essential information below. Expand Full ConOps if you wish to add a complete operational description.
⚡ QUICK LOAD – MISSION FILES
Upload ArduPilot mission files to automatically populate waypoints, calculate flight time and energy.
Formats: QGC WPL 110 (.waypoints) · QGC Plan (.plan) · Litchi CSV
▸ A1 – IDENTIFICATION
Coordinated Universal Time (UTC / Zulu)
Auto-calculated from waypoints and cruise speed
▸ A2 – UAS CHARACTERISTICS (SORA 2.5 QUANTITATIVE GRC)
SORA 2.5 replaces MTOM-based GRC with characteristic dimension (m) and max speed (m/s) as primary parameters (Annex F, Table 2).
Largest dimension (diagonal for multirotor)
Default 10 m/s. Used to calculate flight time from waypoints.
Hover/dwell time per waypoint (hover, photo etc). Default 0 s.
▸ A2b – ENERGY CALCULATION & BATTERY BUDGET
Energy consumption per flight phase as % of total battery per minute.
Values are pre-filled from the UAS database when you select a model above — adjust to match your actual experience.
Fixed overhead before take-off
High power — vertical ascent phase
Horizontal cruise phase
Lower power — descent phase
Recommended ≥20% (RTL margin)
▸ A3 – OPERATION CATEGORY & FLIGHT REGIME
▸ A4 – OPERATIONS VOLUME & LOCATION
Ground risk buffer (SORA 2.5 §2.2.4)
Adjacent area (SORA 2.5 §2.2.5) – used in containment step 8
Adjacent airspace (SORA 2.5 §2.2.6)
▸ A5 – FULL ConOps / DOI (OPTIONAL)
Detailed operational description per SORA 2.5 Annex A. Complete the sections relevant to your operation.
All information here is included in the final briefing document.
Step 2 – Volume Planner
// FLIGHT GEOGRAPHY · CONTINGENCY VOLUME · GROUND RISK BUFFER (DIPUL METHOD)
Configure your operational volumes based on kinematic parameters. The map uses your waypoints from Step 1.
The calculated buffers will automatically carry over to the Containment and Risk Assessment steps.

Steps 2–7 – iGRC · GRC · ARC · SAIL
// SORA 2.5 QUANTITATIVE RISK ASSESSMENT · JARUS JAR-doc-25 TABLE 2
▸ STEP 2 – INTRINSIC GROUND RISK CLASS (iGRC)
SORA 2.5 determines iGRC from characteristic dimension (m) and max speed (m/s) + population density.
Dimensions fetched automatically from DOI step. iGRC scales 1–10; values >7 are outside SORA scope (certification category).
▸ STEP 3 – GROUND RISK MITIGATIONS (FINAL GRC) – ANNEX B
SORA 2.5 categorises mitigations as M1A (sheltering), M1B (operational restrictions), M1C (ground monitoring) and M2 (technical energy reduction on impact).
▸ STEP 4 – INITIAL AIR RISK CLASS (ARC) — DECISION TREE
Initial ARC is determined from the Airspace Encounter Class (AEC) decision tree
[SORA v2.5 Main Body, Figure 6 and Annex C, Table C.1]. Answer each question in order.
▸ STEP 5 – STRATEGIC MITIGATION (RESIDUAL ARC)
The operator may demonstrate that the local manned traffic density in the operational
volume is lower than the generalised AEC rating, reducing the ARC.
[SORA v2.5 Annex C, Table C.2] | Note: AEC 10, 11 and 12 are not in Table C.2.
▸ STEP 6 – TACTICAL MITIGATION PERFORMANCE REQUIREMENT (TMPR)
TMPR is determined automatically from the residual ARC.
VLOS/EVLOS operations are exempt from TMPR — see-and-avoid is an acceptable
tactical mitigation for all ARC levels. [SORA v2.5, Section 4.6.4]

Step 8 – Containment
// NEW DEDICATED STEP IN SORA 2.5 · ANNEX E §E.4
Containment ensures that the Target Level of Safety is achieved in the adjacent area.
In SORA 2.5, containment is a dedicated step (#8) before OSO. Three robustness levels: Low / Medium / High.
Requirements depend on UA size, SAIL, population density in adjacent area, and presence of crowds within 1 km.
▸ ADJACENT AREA
▸ CONTAINMENT MEASURES
// CONTAINMENT ASSESSMENT
Select containment parameters above for assessment.
Step 9 – OSO (17 Operational Safety Objectives)
// SORA 2.5 ANNEX E · OSO #01–09, #13, #16–20, #23–24 · CLICK TO TICK OFF
SORA 2.5 has 17 OSOs with specific numbering: #01–#09, #13, #16–#20, #23–#24.
Note: OSO #10 (from 2.0) has been merged into OSO #05 in version 2.5. Numbers #10–#12, #14–#15, #21–#22 do not exist in SORA 2.5.
Robustness level (Low/Medium/High) is based on your SAIL. Click to mark as fulfilled.

▸ AIRSPACE MAP
In-app maps use ESRI WorldTopo as base layer. With an OpenAIP API key (free account at openaip.net) a complete airspace overlay is added to all maps — CTR, TMA, restrictions, UAS zones etc.
Without a key, no airspace data is shown on the map (use the external links below).
The key is saved in the browser localStorage and loaded automatically on next start.

▸ METAR · TAF (CHECKWX) & MANUAL NOTAM
Fetches METAR and TAF within a 50 km radius via CheckWX.
NOTAMs cannot be fetched automatically (since we do not use US sources and no free European APIs exist). Use the links below for LFV ARO or Eurocontrol EAD and paste manually.
