The Federal Aviation Administration (FAA) is a governmental body of the United States with powers to regulate all aspects of civil aviation in that nation as well as over its surrounding international waters. Its powers include the construction and operation of airports, air traffic management, the certification of personnel and aircraft, and the protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighbouring international waters were delegated to the FAA by authority of the International Civil Aviation Organization

The General Authority of Civil Aviation of Saudi Arabia (GACA‎) is the national institution of Saudi Arabia in charge of aviation and related matters, headquartered in central Riyadh

GACA emerged from the former Presidency of Civil Aviation that was created when the institution controlling aviation was split into a civil department and the Royal Saudi Air Force. The Presidency of Civil Aviation was among others also in charge of the Saudi Arabian Airlines and the Meteorology Department. The Saudi Arabian Airlines was split from the Presidency of Civil Aviation in 1960 and became an independent public institution in 1963. The Meteorology Department became an independent institution with own budget in 1966. The name of the Presidency of Civil Aviation was changed to General Authority of Civil Aviation in 1977.

The General Civil Aviation Authority (GCAA) in the United Arab Emirates (UAE) was established in 1996 by Federal Cabinet Decree (Law 4) to regulate Civil Aviation and provide designated aviation services with emphasis on safety and security and to strengthen the aviation industry within the UAE and its upper airspace. The main office is located in Abu Dhabi and the regional office is located in Dubai to serve the northern Emirates. The GCAA, which is the sole authority for the control and regulation of civil aviation in the UAE, is responsible for the provision of en-route air navigation services and all aspects of flight safety. In late 2009, the GCAA opened its new Air Navigation Centre, The Sheikh Zayed Centre, which is considered the largest and busiest air traffic management facility in the Middle East as well as one of the world’s most technically advanced centres in terms of its design.

The Public Authority for Civil Aviation is the legal personality and administrative independence to the authority responsible for various regulatory and legislative aspects of civil aviation affairs in the Sultanate of Oman. In addition, it works on the provision of air navigation services and the National Service of Meteorology. PACA’s vision is to be renowned for civil aviation safety and security, the excellence of its people and the value it creates for Oman.
