Key information
- Open category standard limit: 120 m AGL — applies in most unrestricted zones.
- Some zones impose lower limits — the UAS map shows them as coloured overlays.
- NOTAMs can reduce the ceiling temporarily even in zones that normally allow 120 m.
- Flying higher than the zone limit without authorisation is an airspace violation.
- Check altitude limits on the UAS map and in active NOTAMs for your specific point and date.
What this means for you
The 120 m rule is a ceiling, not a universal green light. Zone restrictions or NOTAM activations can lower it significantly. Always verify the altitude limit for your exact location, planned time and drone category before take-off. If your plan exceeds the zone ceiling, either fly lower or seek the correct authorisation — do not “try a bit higher”.
After reading the steps, check if you can fly on the exact point or explore the flight zones map. If the zone needs coordination, see the approval request.
How to set the correct altitude
Follow these steps before locking the mission max altitude in the controller.
- Write down the real planned altitude Note in metres AGL what you want to reach (for example 60 m for filming). Do not let a default controller value decide for you.
- Compare with zone details on the map Open the UAS map, mark the point and read vertical limits. Some zones have a ceiling under 120 m; others require approval above a certain level.
- Check the NOTAM for altitude A NOTAM may close only an altitude band. If the restriction intersects your plan, change time, place or ceiling.
- Account for obstacles and CTR Near aerodromes and in CTR, altitude is often more restrictive. Do not use a hearsay “5 km rule” — real limits are on the map.
- Re-check on flight day Even if yesterday the ceiling was 120 m, today a NOTAM can lower it. Repeat the check before take-off.
