When does the ACO execution take place?

The ACO (Airspace Control Order) execution refers to the specific time frame within which the directives outlined in the ACO become effective and are executed in the operational environment. Typically, the execution of an ACO takes place 24 hours after it is issued. This period allows for the necessary coordination and planning among various airspace users, ensuring that all units are prepared to operate under the specified airspace control measures.

In the context of air-ground operations, having a 24-hour window for execution facilitates effective integration of air and ground forces, as it accounts for logistical considerations, mission planning, and adjustments to the operational environment that may arise. Additionally, this time frame provides a balance between allowing adequate preparation and the need for timely response to dynamic battlefield conditions.
