|17B11. Danger space and hitting space
For a given target and trajectory, the danger space is the greatest distance through which the target may be moved in the line of fire and still be intersected at some point by that trajectory. Column 7 of the range table is composed of values of the danger space for a target 20 feet high and of zero depth in the line of fire.
Column 7 of the range tables shows that as range increases the ability to hit the target decreases with range and at maximum range the ability to hit the target is the smallest.
As range and gun elevation increase the ability to hit decreases.
