Aircraft Crash Rates.

DOE-STD-3014-96

APPENDIX B

B.2

Aircraft Crash Rates. Generic crash rates for each aircraft category and subcategory

were calculated based on a review of accident reports published by FAA and/or the

National Transportation Safety Board (NTSB) for civilian aircraft, and by the United

States military for military aircraft. The evaluation techniques used to estimate specific

crash rates for each aircraft category or subcategory are documented in Reference 2.

See this document for more information on the databases and evaluation techniques.

Table B-1 provides the generic crash rates for each aircraft category (and subcategory

as available).

Crash Location Probability. Crash location probabilities per square mile in the vicinity of

B.3

a runway were calculated based on a review of accident reports published by FAA

and/or NTSB for civilian aircraft, and by the United States Air Force for military aircraft.

The probability values are given in a tabular format for commercial, general aviation,

and military aircraft categories (or subcategories as available). The probability values

are a function of distance from an intended runway. Each probability value reflects the

conditional probability that, given a crash, the crash will occur within a specific one-

square-mile bin in the vicinity of an airport. The data and calculations used to

determine the probability values are provided in Reference 2.

Since the crash location probabilities are a function of distance from a runway, it is

important that the coordinate convention specified in this standard be used. Using this

convention, the analyst will determine the facility's location coordinates (x and y

distances) and find the appropriate probability value for the facility.
