CEE 4674: Airport Planning and Design Spring 2011 Assignment 4: Wind Rose and Obstructions to Navigation Solution Instructor: Trani Problem 1 Perform an obstruction analysis for airport shown in Figure 1. The airport has two runways oriented East-West and North-South as shown in Figure 1. Runway 09-27 is a precision runway whereas runway 18-36 is designed as a non- precision runway to offer approaches with a visibility minima of greater than 3/4 of a mile. The figure shows the location of three potential obstructions. Table 1 lists all the runway end elevations surveyed recently. a) The hill is an obstruction to navigation. It violates the approach surface of runway 18/36. b) Hangar is not an obstruction c) Tower is an obstruction. Tower is under the transitional surface. At 2,200 feet from runway, the approach surface width is 830 feet. Therefore, tower is in transitional surface.

Unformatted text preview: CEE 4674 Trani Page 1 of 2 Problem 2 A new airport in New Mexico has been proposed. The airport is expected to receive commercial traffic with the Boeing 767-400 as the largest aircraft operating at the airport. Use the FAA computer program AD42.exe demonstrated in class. a) 20 knots. Boeing 767-400 is ADG C-IV. b) Optimal runway orientation is 04/22 or 05/23. Problem 4 Briefly answer the following questions: a) Simultaneous departures with radar. Independent arrival and departure streams (radar). dependent arrival streams. b) 5,300 feet. c) VFR runway separation. Assumes no wake vortex. d) FAA criteria = 16 knots. Boeing 737-900 has 117 foot wingspan (C-III in FAA parlance). ICAO criteria is based on runway length. g) Any object > 500 feet is an obstacle to navigation and such be labeled as such.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
