How is the maximum range for constructing SDZs determined?

The maximum range for constructing Surface Danger Zones (SDZs) is determined by using the horizontal range corresponding to a 10 Degree Quadrant Elevation (QE). This method is critical for ensuring safety during live-fire training exercises since it takes into account the maximum flight trajectory of the projectile when fired at a 10 Degree angle. At this elevation, the projectiles typically achieve the furthest horizontal distance before descending.

This approach is essential because it allows for a comprehensive analysis of the area that could potentially be impacted by errant rounds, ensuring that safety measures are enacted well beyond the actual target area. It helps in establishing safe zones where personnel and equipment can be protected from any potential hazards associated with the ordnance being used.

While other methods of determining maximum range may involve calculations or considerations based on target positions or average distances of projectiles, they do not specifically account for the tactical implications of quadrant elevations or the standard practices adopted in range safety protocols that prioritize the maximum safe distances to protect individuals and property in vicinity to the firing area.
