The Federal Aviation Administration (FAA) is an agency of the United States Department of Transportation with authority to regulate and oversee all aspects of civil aviation in the U.S. The Federal Aviation Act of 1958 created the group under the name "Federal Aviation Agency", and adopted its current name in 1967 when it became a part of the United States Department of Transportation.

The Federal Aviation Administration's major roles include:

In December 2000, an organization within the FAA called the Air Traffic Organization, or ATO, was set up by presidential executive order. This became the Air Navigation Service Provider for the airspace of the United States and for the New York (Atlantic) and Oakland (Pacific) oceanic areas. It is a full member of the Civil Air Navigation Services Organization.
