CEE 4674 Q2 Trani Page 1 of 4 CEE 4674: Airport Planning and Design Spring 2009 Quiz 2 Instructor: Trani Your Name _____________________________ Pledge signature (this is my own work) ___________________________________________ Problem 1 An airport with a non-precision runway is surveyed for FAR Part 77 analysis. The airport has a WAAS approach with visibility minima down to ¾ of a mile. The airport is designed for aircraft larger than utility category. Determine if the following objects surveyed around the airport constitute obstacles to navigation using FAR Part 77 regulations. State the critical surface in question. 1) A 152-foot antenna located 6,200 feet from the runway end and offset 300 feet to the right hand side of the runway centerline extension. The antenna is an obstruction. At 6,000 feet from primary surface the approach surface can be 176.5 feet tall (6000/34): OK. But the horizontal surface dominates at 150 feet. So the antenna violates the horizontal surface. 2) A 78-foot tree located 800 feet perpendicular to the runway centerline.

### What students are saying

• 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.
