CEE 4674 Homework 5 Spring 2009Dimension Length - feet (meters) RemarksK 93 (28.5) Taxiway to fixed/movable object (Table 2-3)P 1000 (300) RSA length beyond runway end (Table 3-3)Q 800 (244) ROFA width (Table 3-3)R 1000 (300) ROFA beyond runway end (Table 3-3)W 50 (15) Taxiway width (Note that landing gear wheelbase is less than60 feet) (Table 4-1)Z 81 (24.5) Taxilane to fixed/movable object (Table 2-3)b)Find the size of the runway and taxiway shoulders needed at this airport.The runway shoulders need to be 20 feet (6 meters) (Table 3-3). The taxiway width will be 20 feet (6 meters) (Table4-1).c)Assuming the top of Figure 2 is the North side of the airport, find the closest distance from the runway that adeveloper could build a 4-story hotel (say 50 feet tall). Explain the controlling surfaces and dimensions considered inyour analysis.Surfaces to be tested: 1) Transitional surface extending at a slope 7:1 outwards from the primary surface and 2) therunwayTransitional surface drawingFigure 3. Transitional Surface Schematic.From figure 3 it is clear that the hotel is restricted to a minimum of 850 feet from the runway centerline. This will be incompliance of the Part 77 transitional surface.Runway OFZ surface schematic.Figure 4. Runway OFZ Surface Schematic.According to FAA design standards, “for CAT I runways, the inner transitional OFZ begins at the edges of the runway OFZ andinner-approach OFZ, then rises vertically for a height "H", and then slopes 6 (horizontal) to 1 (vertical) out to a height of 150 feet(45 m) above the established airport elevation.”The dimension of H is given by, 3
