(2) Identify appropriate containment levels and risk associated with the areas identified as needing specific risk analysis, or the area of critical concern. (3) Identify possible or improved target locations. (4) Modify allowable delivery ground tracks to eliminate or reduce hazards. (5) Identify the best locations for range modifications or improvements. (6) Design a new target area/range. c. The methodology is based on a combination of weapon modeling/simulation data and actual impact data. Each WDZ incorporates a probability distribution function which provides the information necessary to perform a quantita- tive risk assessment to evaluate the relative risk of an identified profile. d. Every type of air-to-ground aviation ordnance should have a WDZ. This WDZ (the weapons footprint) is calculated based on the type of aircraft delivering the weapon (for example, F/A–18 Hornet aircraft or OH–58D Kiowa helicopter), the delivery parameters of the aircraft (dive angle, airspeed, altitude, and so forth), type of ordnance being delivered (for example, MK–82 bomb and AGM–114 HELLFIRE missile), and the level of containment desired. e. WDZs may be further affected by terrain, artificial barriers, or other compensating factors such as target type (wood, metal) and soil hardness. f. Representative examples and descriptions of WDZs are reviewed in chapter 3. 11–7. Weapon danger zone tool a. WDZs for FW, RW and UAS are generated with the WDZ tool as part of the RMTK package. The WDZ tool is a Geographic Information System-based application that is available to operational planners and RMAs (Army), RCOs (Marine Corps) in both desktop and web-based versions. b. The WDZ tool will lead the user through the WDZ generation process. It will help range managers determine aircraft type, ordnance, and delivery parameters that are permissible for each target. c. A record (electronic or hard copy) of the analysis of each target engaged during the training evolution will be maintained at range operations (Army), range control (Marine Corps). The WDZ manager (library function) may be used to meet this requirement. d. Range operations (Army), range control (Marine Corps) personnel will publish air-to-ground ordnance delivery regulations for each target in the range SOP, specifying ordnance permitted as well as any restrictions (dive angle, airspeed, run-in heading) associated with that target or specific training event. Proper target analysis will include, but is not limited to the following: (1) Approved ordnance for the range target. (2) Type of deliveries allowed. (3) Run-in restriction if required for a specific weapon or delivery. (4) Approved containment boundary. (5) Weather minimums if more restrictive than standard visual flight rules operating requirements. (6) Any other constraints or restrictions required to allow weapons delivery on the identified target. e. For deliveries not contained within the SOP, the using unit may submit proposed WDZs to the range operations office (Army), range control office (Marine Corps) for consideration. f. WDZs will be developed and tested as new weapons, aircraft, and delivery parameters are produced and enter the operational inventory. Appropriate higher headquarters will ensure WDZs are available prior to levying new weapons training requirements or introducing new aircraft and weapons into the DOD inventory. g. The WDZ tool is an integral application of RMTK and may also be accessed on the web: (1) Army: Sustainable Range Program Web site - https://srp.army.mil. (2) Marine Corps: RTAM Web site - https://rtam.tecom.usmc.mil. 11–8. Applying the weapon danger zone tool a. Containment. (1) The "containment" of a weapon system’s performance envelope, impact footprint, and/or associated debris fields require the surface area (land or sea) to be protected by purchase, lease, or other restriction to exclude personnel from that area. This general policy ensures safety will be maximized and consistent with mission requirements. (2) The WDZ tool allows selectable levels for weapons containment ranging from 1:10,000 probability to a 1:1,000,000 probability of a munition escaping the containment area (for inert ordnance) or a live weapon’s fragment escaping the containment area (for live ordnance). (3) The safety standard for Army and Marine Corps ranges is 1:1,000,000. (a) Fixed wing aircraft. All WDZs will be generated with a minimum containment standard of 1:1,000,000 (99.9999 percent). (b) Rotary wing and tilt rotor aircraft. All WDZs will be generated with a minimum containment standard of 1:1,000,000 (99.9999 percent). 142 DA PAM 385–63 • 16 April 2014
