(c) Unmanned Aircraft System. All WDZs will be generated with a minimum containment standard of 1:1,000,000 (99.9999%). (4) For the Army, if the selected containment level is too large to support necessary operations, a smaller containment level may be accepted with the completion of an appropriate risk analysis and deviation process referenced in AR 385–63/MCO 3570.1C, and FM 5–19. For the Marine Corps, if the selected containment level is too large to support necessary operations, contact Commanding General, Training Education Command, Range and Training Area Management Branch (C465), 3300 Russell Road, Quantico, VA 22134–5001 for assistance in development of the appropriate risk analysis and deviation process referenced in AR 385–63/ MCO 3570.1C FM 5–19, and MCO 3500. 27B. (5) Subject to deviation, WDZs may be further reduced by selecting the option to mitigate for terrain. (6) Deviations approved for WDZs extending beyond installation boundaries must be based on the ability to contain projectiles, hazardous fragments, laser beams, and both vertical and horizontal ricochets sufficiently within the installation boundaries, and area under military control (such as leased land or training areas and facilities acquired through memorandum of understanding or memorandum of agreement). Probability of hazardous fragment escapement must not present a greater than 1:1,000,000 hazard to the public. b. Mission essential personnel. (1) Placement of mission essential personnel (MEP) within a WDZ may be authorized by the RMA (Army), RCO (Marine Corps) or the operational commander of the training or exercise. (2) Essential personnel are those personnel directly related to the employment of live/inert ordnance (air, surface, or sea fires) in an exercise or evaluation on a training range in a training/evaluation scenario (all those people that are receiving/giving the training and or receiving/giving the evaluation). This would include JTACs, tactical air control parties, maneuver elements, fires elements (air/land/sea), and instructors/evaluators. c. Risk analysis. (1) The WDZ tool risk analysis function can show the probability of impacts within a selectable, defined area of the WDZ. This function will help define the risk associated with a specific location within the WDZ, dependent upon the weapons system employed and the size of the area at risk or area of critical concern. (2) Area of critical concerns may involve the placement of MEP (such as, JTAC or tactical air control parties) or the location of towers or other facilities within the WDZ. For area of critical concerns that contain MEP, the RMA (Army), RCO (Marine Corps), or the OIC will use the WDZ Tool Risk Analysis function and will not accept greater risk than the safety standard of 1:1,000,000 unless a thorough risk assessment, risk management process has been completed per reference FM 5–19 and MCO 3500.27B. (3) Risk may be mitigated by moving the location of the personnel, decreasing their vulnerability through the use of terrain features or bunkers, or reducing the dimensions of the area. (4) Non-participating personnel must be outside the WDZ at all times. 11–9. Rotary wing surface danger zones a. General. (1) SDZs will be used for RW aircraft when WDZ generation is not available. (2) For firing from a hover, SDZs will be superimposed over the GTL at each firing point. On running fire courses, SDZs will be superimposed over each anticipated firing position along the course. These SDZs will begin at the start- fire line and move along the course to each anticipated firing point to the cease-fire line. (3) A range may contain several different hover fire points or running fire courses where multiple aircraft can fire at the same time. The resultant SDZ will be a composite formed by individual SDZs. When multiple aircraft are firing at the same time, controls will be established to ensure the safety of all participating aircraft. (4) The lateral limits of the target area determine the left and right limits of fire, which will begin at any point beyond the start-fire line provided the minimum safe distance (for example, ricochet area, Areas A and B) for the weapon system being fired is maintained from the aircraft to the point of impact. For running fire, Distance X will be measured from the cease-fire line. b. Guns and Cannon. SDZ requirements for safe firing of 7.62mm, .50 caliber machine guns, and 20mm and 30mm cannons from RW aircraft are given in chapter 4. c. Rockets. (1) SDZ requirements for the safe firing of the 2.75 in folding fin aerial rocket weapon systems from rotary-wing aircraft for hover and running fire are given in table 11–2 and figures 11–2 and 11–3, and are the basis for constructing the SDZ. (2) The distance from the cease-fire line or disarm line to the closest edge of Area B will be Distance X for the weapon system being fired. (3) Areas A and B are not required for inert/training munitions. For HE warhead-equipped rockets, Areas A and B are 300 m wide. For flechette warhead-equipped rockets, Area A is 300 m wide and Area B is 400 m wide. 143 DA PAM 385–63 • 16 April 2014
