101st Airborne Division (Air Assault) Gold Book

ANNEX C - Army Aircraft Command and Control


1. Airspace control goals.

a. Enhance combat operations and increase operational effectiveness of all forces.

b. Minimize friendly fire losses.

c. Provide for the safe and expeditious movement of air traffic.

2. Airspace control fundamentals.

a. Airspace is a joint medium used by all components.

b. Provide maximum allowable freedom consistent with the degree of risk the

commander considers acceptable.

c. Permit close coordination between ground, naval, and air operations.

d. Enhances combat operations.

e. Allows rapid concentration of combat forces.

3. Objective area airspace must:

a. NO IDLE WEAPONS: Facilitate the integration of maximum combat power/strike

capability simultaneously. There must be no idle weapon systems.

b. NO SANCTUARY FOR THE ENEMY: Allow no sanctuary for the enemy. There

can be no safe haven for the enemy to run to, or area that restricts engagement by our weapons.

c. BE FLEXIBLE: It must be capable of adapting to expanding and contracting

operations without preventing the use of weapons systems or allowing the enemy an unbeaten

zone to hide in.

d. BE DOCTRINAL. It must integrate with joint procedures and support the way we


e. BE EASY to use, safe, and fast.

4. To meet the goals and fundamentals of airspace control, as well as the criteria established for

the objective area, the following standard has been established:

a. The objective area and security zone airspace will be subdivided into high-density airspace control zones (HIDACZs). Each HIDACZ will be numbered, with the highest number being the central HIDACZ. The central HIDACZ will cover the immediate division objective area. (See diagram).

b. The number of HIDACZs will vary in relation to objective area and security zone size, maneuver graphics, and natural boundaries.

c. Outer boundaries will correspond to the outer maneuver boundary provided from higher headquarters and is comprised of the outer boundary of the security zone. Inner dividing boundaries will be matched to maneuver graphics and/or landmarks. The HIDACZ boundaries should match maneuver graphics to allow common phase lines and boundaries for both aviation and ground use. The airhead line must allow sufficient airspace around objectives for aviation assets to support ground operations within the airhead.

d. Altitude will generally match that of the published coordinating altitude in terms of feet above ground level.

e. HIDACZs must be forecasted, requested, and activated through the ACO cycle. This allows all joint aviation elements to pre-plot the HIDACZs, even if they are inactive. This facilitates the rapid activation and deactivation of a HIDACZ in an immediate change scenario. Additionally, it allows for terminal CAS controllers to utilize the HIDACZs as a means of guiding CAS aircraft. With proper planning, maximum flexibility and application of combat power realized.

f. The HIDACZs are activated in different groups and times (or both) as determined by the situation. The following paragraphs clarify the activation of HIDACZs by time or group.

(1) Time activation. Activation of HIDACZs by time provides for the restriction only when we use the airspace and frees it for unrestricted use by joint assets at all other times. This provides joint aircraft the greatest flexibility while providing us control while in the objective area.

(a) Deep attacks to set conditions or raids. HIDACZs are activated by time to support condition setting deep attacks and deactivated when the deep attacks conclude.

(b) Air assault operations. HIDACZs are activated to support air assaults and remain in effect until follow on forces bypass the HIDACZs.

These activations will last for a significant period of time. This is a common scenario where the HIDACZ must also be activated by group.

(2) Group activations. The HIDACZs can be activated individually or as a group. This provides for maximum flexibility of division aviation assets and joint aircraft. For example: If attack aviation is operating in HIDACZs 5, 6, and 7 (See diagram), this frees HIDACZs 3, 4, 1, and 2 for joint strike assets.
