Altitude and Flight Forces - Worksheet

 
  1. Compare and contrast the following forces on an airplane: weight, lift, thrust, and drag.






     

     

  2. Alter the altitude of the given airfoil. Enter values in the following table. As the altitude changes, what happens to the density, pressure, temperature, and lift quantities?
    Altitude
    4763
    12864
    17775
    25500
    30000
    36000

  3. Compare the information obtained about the forces on an airplane with the table information. What is the implication of the changes in altitude on the forces affecting the flight of an airplane? Think this through carefully.









     

  4. As the altitude changes, what happens to the graphs seen in the Plotter View Panel window?

     

     

  5. What are the implications or importance of the yellow and white graphs seen in the Plotter View Panel window? Think carefully.
