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 M expression: P = C x A M where: C = total probability of an aircraft crash per square kilometer (square mile) per 47 year in the vicinity of the site due to the airports being considered, and A = effective area of one unit of the plant in square kilometers (square miles) . 48 Where estimated risks due to military aircraft activity are found to be unacceptably high, suitable airspace or airway relocation should be implemented. Past experience has been that military authorities have been responsive to modification of military operations and relocation of training routes in close proximity to nuclear power plant sites. (Ref. 12) 49 5. Holding Patterns. Holding patterns are race track shaped courses at specified altitudes, associated with one or more radio-navigational facilities, where aircraft can "circle" while awaiting clearance to execute an approach to a landing at an airport or to continue along an airway. Holding patterns which are sufficiently distant
