Because aircraft accidents happen infrequently <br /> and the time,place, and consequences of their occurrence cannot be predicted,the concept of risk <br /> is central to the assessment of safety compatibility. From the standpoint of land use planning,two <br /> variables determine the degree of risk posed by potential aircraft accidents: <br /> • Accident Frequency: Where and when aircraft accidents occur in the vicinity of an airport; <br /> and <br /> • Accident Consequences: Land uses and land use characteristics that affect the severity of <br /> an accident when one occurs. <br /> SafetyZones4on8an .Carlos'Airporty <br /> The 2011 Handbook provides a series of generic compatibility zones for general aviation airports. <br /> While the general dimensions of these zones are largely a function of the size of the <br /> corresponding runway,the geometric patterns of the zones were designed to capture areas in the <br /> vicinity of an airport where the risk of an aircraft accident are greatest. Where an aircraft accident <br /> may occur is driven by aeronautical considerations; that is,the geography of risk is determined by <br /> SanfCarlosfAirportV 3-12 ESAfAirportsf/130753' <br /> ALUCPf W hitef Pape/ Junef2014f <br />
