Air Transportation Oversight System (ATOS)

The Air Transportation Oversight System (ATOS) implements FAA policy by providing safety controls (i.e., regulations and their application) of business organizations and individuals that fall under FAA regulations. Three major functions further define the oversight system: design assessment, performance assessment, and risk management.

• Design assessment is the ATOS function that ensures an air carrier’s operating systems comply with regulations and safety standards.
• Performance assessments confirm that an air carrier’s operating systems produce intended results, including mitigation or control of hazards and associated risks.
• Risk management process identifies and controls hazards and manages FAA resources according to risk-based priorities.

For more information on ATOS, please see 8900.1 Volume 10 of FSIMS (Flight Standards Information Management System).
