1.8 Flying over buildings
The maximum flying altitude for unmanned aircraft in the Open category is 120 metres (400 ft) above ground level (AGL).
On a national
level, countries may determine geographical areas in which lower maximum
altitudes apply. As a remote pilot, you must obviously comply with these limits
and, if necessary, fly with an observer.
