An air tasking order (ATO) is a means by which the Joint Forces Air Component Commander (JFACC) controls air forces within a joint operations environment. The ATO is a large document written in United States Message Text Format (USMTF) that lists air sorties for a fixed 24-hour period, with individual call signs, aircraft types, and mission types. NATO uses a different text format, “.ato”. The ATO is created by an Air Operations Center (AOC) which has command and control for a particular theater. More specifically, the Combat Plans Division of the AOC is responsible for creating the ATO, as well as the associated Airspace Control Order (ACO) and linked detailed information in the Special Instructions (SPINS).
