The key legislation governing aviation in Germany includes the German Air Traffic Act, the Air Traffic Order, and the Aviation Security Act. The Federal Aviation Office (LBA) regulates civil aviation as the supreme authority. To obtain an operating license, air carriers must hold an Air Operator Certificate, have aircraft available, civil aviation as their main occupation, meet ownership and control requirements, and comply with financial, insurance, and good repute provisions. Air safety is primarily governed at the European level by the Regulation on common aviation safety rules and the European Aviation Safety Agency administers air safety. The LBA is responsible for supervision and the German Aircraft Register at the national level in Germany.
