rts and Heli-Ports (Refs. 2, 4, and 14). The probability of an aircraft crashing into the site should be estimated for cases where one or more of the conditions in Item II.1 of the Acceptance Criteria are not met. The probability per year of an aircraft crashing into the site for these cases (PA) may be calculated by using the following expression: L M PA = 7 I ; l Ni Aj w=l J=l where: I I I M L C. N.. A. number of different types of aircraft using the airport, number of flight trajectories affecting the site, probability per square mile of a crash per aircraft movement, for the jth aircraft, number (per year) of movements by the jth aircraft along the ith flight path, and effective plant area (in square miles) for the jth aircraft. The manner of interpreting the individual factors in the above equation may vary on a case-by-case basis because of the specific conditions of each case or because of changes in aircraft accident statistics. I Values for C. currently being used are taken from the data summarized in 3 the following table: Distance From End of.Runway (miles) 0-1 1-2 2-3 3-4 4-5 5-6 6-7 7-8 8-9 9-10 Probability (x 108) Mile per U.S. Air Carrier1 16.7 4.0 0.96 0.68 0.27 0 0 0 0.14 0.12 of a Fatal Crash per Square Aircraft Movement General Aviation7 USN/USMC1 '84 15 6.2 3.8 1.2 -NA NA NA NA NA 8.3 1.1 0.33 0.31 0.20 NA NA NA NA NA USAF" 5.7 2.3 1.1 0.42 0.40 NA NA NA NA NA lReference 2. 2 Reference 4. 3 NA indicates that data was not available for this distance. 3.5.1.6-4 Rev. 2 - July 1981 1 4. Designated Airspaces. For designated airspaces involving military or civilian usage, a detailed quantitative modeling of all operations should be verified. The results of the model should be the total probability *(C) of an aircraft crash per unit area and time in the vicinity of the proposed site. The probability per year of a potentially damaging crash at the site due to operations at the facility under consideration (P.) is then given for this case by the following
