CEE 5614: Analysis of Air Transportation Systems Fall 2011 Assignment 4: Air Transportation Systems Analysis Date Due: October 17, 2011 Instructor: Trani Problem 1 The National Airspace System is a complex system with thousands of commercial flights each day. The file nasOperations_2011.xls contains a sample of the activities that happened in the NAS on December 20, 2008. The header and a few flights are illustrated in Table 1. Table 1. Sample NAS Flights File. Examine operations in the NAS performed using wide-body transport aircraft represented by the Boeing 767 family (models B762, B763, B764 and B767) and Airbus A330 family represented by the following models: A330, A332, and A333. a) Find cruise flight levels assigned to all modern wide-body aircraft stated above and establish a possible correlation between cruise flight level and distance flown. Plot and find the best fit model. Explain the trends observed. Figure 1. Plot of Cruise Altitude vs Distance Flown for Boeing 767 Family of Aircraft. CEE 5614 A4 Trani Page 1 of 10

Discussion: Only data in the first 500 nm miles seems to follow a pattern. The rest of the data is quite random and a good model cannot be developed. b) For the aircraft fund in Part (a), create a histogram representing the stage length flown by the aircraft vs frequency of operations flying a given range of distances. I suggest you partition the range of distances into 15-30 bins. Figure 2. Histogram of Distances Flown by Boeing 767-300 Aircraft. Mean distance flown is 3,006 nm. c) Compare the histogram of distance flown by wide bodies and compare to that of the Boeing 777 family (B772, B77W and B773). Comment on the difference observed.

### 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.
