GO/NOGO weather analysis for your drone missions

A generic weather verdict says nothing about your flight. Drone OPS Mission calibrates the decision on the drone model you will actually fly: its wind resistance and operating temperature range, combined with real wind from Météo-France's AROME model (1.5 km), gusts, visibility and the geomagnetic Kp index for GPS-sensitive operations. The result is a GO / GO with conditions / NO-GO, with every factor still shown with its value, its threshold and its reference.

How it works

AROME France HD wind, automatic fallback

Wind, gusts and direction come from Météo-France's AROME model at 1.5 km resolution, served via Open-Meteo. Outside the AROME domain or beyond its forecast horizon, the calculation automatically switches to a global model — and the data source remains displayed.

EASA thresholds combined with manufacturer limits

Each verdict combines the regulatory framework (EU Regulation 2019/947, French Order of 3 December 2020) and the limits published by the manufacturer for your model: wind resistance in m/s and operating temperature range.

Geomagnetic Kp index for GPS/RTK flights

Geomagnetic activity (source: NOAA SWPC) is built into the verdict: from Kp 5, compass and RTK positioning reliability degrade and the flight goes on alert.

Never a silent GO on missing data

If a source is unavailable, the factor concerned is not ignored: it switches to “check manually” with the official source to consult. Missing data can never produce a default green light.

Why this differs from a regular weather app

Field wind in m/s, not a daily average

A consumer weather app shows a daily average, in km/h, at shelter height. Here, wind and gusts are given hour by hour in m/s at 10 m — the unit and time scale in which your drone's limits and the operating rules are written.

Calibrated per drone, not a single threshold

12 m/s does not mean the same thing for a 249 g C0 and a 4 kg C2. The verdict is recalculated for the model selected in your fleet: the same weather slot can be GO for one and NO-GO for the other.

Frequently asked questions

Which weather data is used for the drone verdict?

Drone OPS Mission uses Météo-France's AROME model via Open-Meteo when available, and clearly displays the fallback model if the area or forecast horizon falls outside the AROME domain.

Why is drone weather different from consumer weather?

The verdict takes wind and gusts into account hour by hour, in m/s, then compares them with the manufacturer thresholds of the selected drone model. A daily weather average is not enough to prepare a flight.

Does the weather GO/NOGO officially authorise the flight?

No. The verdict is decision support. The remote pilot must always check official sources, actual on-site conditions and their regulatory obligations before take-off.

To complete before take-off

Weather is never enough on its own: always cross-check the chosen time slot with airspace constraints and the height actually available over your mission area.
