The average parking area required was calculated by multiplying the average aircraft length plus 2 <br />times the additional clearance margin by the average aircraft wingspan plus 2 times the additional clearance <br />additional clearance margin. <br />Based on these calculations and the San Marcos Regional Airport peaking <br />characteristics described in the Forecast Chapter, Table 4-21 shows the estimated <br />amount of apron space that will be required at the airport during the forecast <br />period. <br /> <br /> <br /> <br />Facility Requirements Chapter Page 65 of 70 <br />October 2020 <br /> <br />
