This calculator is used to determine the vertical danger area about which it necessary to warn air traffic of detonations taking place on the ground. This warning may be published through a Notice to Airmen (NOTAM) filed with aviation authorities.
The equations for this calculation are as follows:
For single ammunition item only:
Distance = 314(AUW)1/3
For multi-item fragmenting munitions:
Distance = 470(AUW)1/5
