Generally in the case of an aerodrome or an area designated for take-offs and landings of aircraft, it is always necessary to negotiate the intended operations in advance with the operator of that aerodrome or area (Section 13 of the Decree No. 108/1997 Coll., as amended).

In case of using any area other than the above mentioned, it is always necessary to obtain a written consent of the owner of the area (Section 14 of the Decree No. 108/1997 Coll., as amended).
