The mission of the FAA

The mission of the FAA is to provide the safest and most efficient aviation system in the world. Because the aviation sector is highly susceptible to change, it is an ongoing process. The operational branch of the FAA, the ATO, is responsible for achieving the mission.


The Air Traffic Organization (ATO) is responsible for delivering safe and efficient air navigation services to all of the United States, large parts of the Atlantic and Pacific and the Gulf of Mexico. These areas cover more than 17 per cent of the airspace in the world. The total surface area of the airspace is 29.4 square miles.

The American air traffic system is currently experiencing the safest period in its history due to the robust safety culture of the ATO. The ATO can identify risks before there is a safety problem. This is due to the implementation of its proactive safety management system.
