The following sections summarize the data <br /> and assumptions used to develop the future conditions (2035)noise exposure contours presented <br /> in Chapter 3 of this white paper. <br /> A.6.1 v 4nnualv4verageNDayvOperationsNbyv4ircraftvTypev <br /> 2035 AAD operations by aircraft type, operation type(i.e., arrival, departure,touch-and-go), and <br /> time of day are summarized in Tableal-5ffit the end of this appendix. Touch-and-go operations in <br /> the INM consist of an arrival and a departure. The number of touch-and-go operations at San <br /> Carlos Airport in 2035 was calculated by dividing local operations by two. <br /> A.6.2vTimewfiDayw <br /> Based on conversations with airport management and operations personnel it is assumed that 94% <br /> of the operations at San Carlos Airport in 2035 will occur during daytime hours,4%of the <br /> operations will occur during evening hours, and 1%of the operations will occur during nighttime <br /> hours. <br /> A.6.31Runway' Jsev <br /> Runway use information for future conditions(2035) is presented in Tabled-6. It is assumed that <br /> runway use patterns will not change over time at San Carlos Airport and hence runway use data <br /> for existing conditions and future conditions are identical. <br /> TABLE'A-6v <br /> FUTURECONDITIONS∎(2035)1RUNWAYvUSEIBYvOPERATIONvTYPE ASANICARLOSv4IRPORTv <br /> v OperationvTypev <br /> Runwayv Arrivalv Departurev Touch-and-Gov <br /> 12f 20%f 20%f 20%f <br /> 30f 80%f 80%f 80%f <br /> fSOURCEf SanfMateof Countyf PublicfWorksfAirportsf DivisionfMarchf2014f <br /> SanfCarlosfAirportV A-9 ESAfAirportsf/130753f <br /> ALUCPf W hitef Pape/ Junef2014f <br />
