Unmanned free balloon; application for an ascent permit

A permit is required to operate unmanned free balloons ("weather balloons").



An unmanned free balloon may be operated only if the impact of the balloon or any part thereof, including the payload, with the earth's surface will not endanger persons or property.

Special notes

Unmanned free balloons can be divided into different classes (light, medium and heavy) depending on their weight and payload. Depending on the total mass and place of ascent of the free balloon, it may be necessary to obtain an air traffic control clearance from the responsible air traffic control office in addition to applying for the permit.
