Figure 4 Departure Path of an Aircraft over the PT
Arrival on 17C elevation computation
The arrival path of an aircraft over runway 17C on the NE quadrant of the PT is shown in Figure
5. The FAA has defined that the arrival path at a 34:1 slope to reach a minimum height of 72
feet needed from the PT centerline for clearance of an aircraft taxiing on the PT. The 34:1 slope
begins at 200 feet from the end of the runway as shown in Figure 5. The actual elevation at the
end of runway 17C, the elevation of the 34:1 slope at the centerline of PT, and the thirteen feet
high visual barrier elevation are shown in the figure. A Category E aircraft is taxiing on the PT
for take off from runway 17R after leaving from the NE freight apron area. The proposed
thirteen feet high visual barrier located at a distance of 1,100 feet from the north end of runway
17C is shown. The PT centerline is 2,650 feet from the north end of runway 17C. The aircraft is
flying at a mean height of 208 feet above PT centerline.
