structures (e.g., munition storage bunkers and seismically qualified process and

storage buildings), extremely rocky terrain, soft soil, dense forests, ravines, and

canyons. These special conditions could permit the analyst to reconsider the angle of

impact and the skid length for the aircraft of interest. If, for example, the nearby robust

structure is tall with respect to the facility, the angle of impact might be considerably

larger than the mean value recommended, resulting in a substantially smaller effective

target area. The higher angle of impact may result in a reduced or negligible skid

length, which could also reduce the effective target area. In addition, if the facility is

surrounded by other buildings, the skid distance will not be greater than the largest

distance between these buildings and the facility.

Sample Problem. The following sample problem will take the reader through the steps

B.5

described in Section 5.3 of the standard. A facility with three airports within a 22-mile

radius will be considered, as shown in Figure B-4.
