CEE 4674: Airport Planning and Design Spring 2011 Assignment 4: Wind Rose and Obstructions to Navigation Date Due: March 1, 2010 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. Figure 1. Airport with 3 Potential Obstructions. Elevations in Parenthesis are Above Mean Sea Level Conditions. Table 1. Surveyed Runway End Elevations.
