What guidelines were used to construct single event noise maps in the study?
It is standard practice to generate Sound Exposure Level (SEL) contours for the loudest aircraft. SEL contours were prepared for the south runway for the existing case. SEL contours also were prepared for the north runway using current departures to show the effect of the shift of some jet aircraft from the south runway to the north runway. It was deemed inappropriate to show the SEL contours on both runways on the same map because the contours depict a single aircraft operation and the runways would not be used for simultaneous jet departures on the 50 degree heading.
