 A MOA is a type of special use airspace (SUA), other than restricted airspace or prohibited airspace, where military operations are of a nature that justify limitations on aircraft not participating in those operations.The designation of SUA's identifies for other users the areas where military activity occurs, provides for segregation of that activity from other fliers, and allows charting to keep airspace users informed.Local flight service facilities maintain current schedules and contacts for the agency controlling each MOA.
