Aviation Legislation

This page summarises the principal legislation governing civil aviation in the United Kingdom and the European Community.

The CAA uses a mix of international, European and domestic legislation to protect consumers. This ranges from the minimum safety standards laid down by the International Civil Aviation Organisation (ICAO), to EC legislation protecting passengers rights, European legislation on safety issues such as pilot licensing and domestic regulation on the use of airspace.

The prime UK legislation is detailed in the Civil Aviation Act and the Air Navigation Order. These provide the key domestic legislation that the CAA uses in its day-to-day business.
