4. (50 Points) Investigate the flight characteristics of the Cessna Citation aircraft. Given the wing span dimensional length as well as tapering chord length when either the NACA 2412 or the NASA/Langley 0213 airfoils are used. Evaluate the angle of attack of the wings attached to the fuselage when at straight and level flight 22,000 feet. Compare the performance during take off and landing (different angles of attack) in the range of environments at DeKalb Taylor Municipal Airport (i.e. super hot or super cold days). At what climb rate could the Citation have some concern about reaching stall condition and lose lift? Extra Credit: (20 Points) Confirm the scaling of the airfoil lift and drag performance as the same shapes could be used on larger aircraft like the Embraer E135/145 or Airbus A320.
