Chapter 2 2-8 ADP 3-90 31 July 2019 operations among subordinate units. These procedures and annexes ensure consistency with joint airspace procedures, the theater airspace control plan, aeronautical information publications, and associated plans and orders. To support the division mission, the airspace elements are responsible for—  Providing airspace control expertise for the commander.  Monitoring joint airspace operations.  Planning and updating input to the joint airspace control plan.  Integrating the airspace control architecture into the joint airspace control architecture.  Developing the airspace control architecture to support plans.  Drafting all airspace control input for operation orders, operation plans, appendices, and running estimates.  Planning and requesting airspace coordinating measures.  Deconflicting airspace through the appropriate authority.  Coordinating with the movement and maneuver (for aviation), intelligence (for information collection), and fires and protection (for air and missile defense) cells.  Providing air traffic service expertise to the headquarters. 2-35. The division airspace element oversees airspace control for all of the division’s assigned airspace. When a division allocates part of its AO to a subordinate brigade, it delegates some airspace management responsibilities to that brigade. However, the division airspace element still integrates airspace users over the entire division AO. If the division has an unusually large AO or if the division AO is noncontiguous, then it can delegate more airspace control responsibilities to subordinate units. Normally, delegation of airspace control for unified action partner airspace requires significant augmentation of the brigade with organized, trained, and equipped airspace control personnel from both the Army and the Air Force. Division and Corps Airspace Management 2-36. If required, the division headquarters provides airspace control to support multinational forces under the operational control of the division. If these forces lack airspace control capabilities, they require assistance from the division airspace element. They receive support similar to Army functional brigades working directly for the division. Airspace elements provide airspace control subject matter expertise for planning. Airspace planning focuses on near-real-time airspace control during a mission and provides commanders flexibility while reducing risk. 2-37. The United States Air Force aligns air support operations center capabilities with Army divisions. Aligning air support operations centers provides an effective method to command and control close air support, intelligence, surveillance, reconnaissance, and air interdiction operations. Aligning air support operations centers also provides an effective means to coordinate suppression of enemy air defense in division-assigned airspace. 2-38. Army airspace planners at the senior operational and tactical levels help to develop the joint airspace control plan. Their participation is critical if they intend to request the authority to control division-assigned airspace using the JAGIC technique. (See ATP 3-91.1 for a description of these functions.) As shown in figure 2-2, division-assigned airspace is airspace in which the airspace control authority delegated the responsibility for control of that airspace to the division, in accordance with the airspace control plan and airspace control order. Division-assigned airspace is assigned by the airspace control authority and is normally that airspace between the rear boundary and the FSCL, between the lateral boundaries up to the coordinating altitude. The coordinating altitude is airspace coordinating measure that uses altitude to separate users and as the transition between different airspace control elements (JP 3-52). This delegation of authorities does not include authorities vested in the area air defense commander. A JAGIC-enabled division is manned and equipped to control procedurally the tactical airspace over the division AO, within division-assigned airspace. The coordination level is a procedural method to separate fixed- and rotary-wing aircraft by determining an altitude below which fixed-wing aircraft normally will not fly (JP 3-52).
