Verdict categories
- Good to Fly — all parameters within profile thresholds; capture conditions are good.
- Marginal — one or more recommended tolerances breached. Drone is operable but capture quality may be affected, or wind/cloud is close to the limit. Final call rests with the pilot based on site conditions, payload stability, mission requirements and JSA.
- Not Good to Fly — a hard safety limit is exceeded (drone manufacturer wind envelope, temperature out of range, precipitation, etc.) or multiple capture-quality limits are stacked.
How the verdict is calculated
For every hour, the app scores cloud cover, wind, gusts, precipitation probability, visibility, temperature, and solar elevation against the active profile's thresholds. Hard safety limits (e.g. the drone's published wind resistance) trigger an automatic NO-GO. Recommended capture-quality tolerances trigger a Marginal — the pilot decides whether to launch.
Weather sources
The app pulls forecasts from four independent providers in parallel: Open-Meteo (primary), Open-Meteo · GFS, Met Norway, and OpenWeatherMap One Call 3.0. When sources disagree on critical metrics, the divergence is shown openly in the Sources section rather than presenting a single model's output as authoritative.
