In 1946 a Directorate on Air Communications was established subordinated to the Council of Ministers. In 1948 the Law on Aviation came into force and it went through a series of amendments over the years until the Civil Aviation Act of the Republic of Bulgaria evolved. As a result of the increased requirements to civil aviation in 1966 the State Economic Association "Bulgarian Civil Aviation" was established. In 1967 the Republic of Bulgaria ratified the 1944 Chicago Convention on International Civil Aviation and became a member of the International Civil Aviation Organisation. BULATSA is an EUROCONTROL member since 1997. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BULATSA」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
