  4. A “stable” aircraft wing design is one where the
  5. Normally, the ailerons are used to produce rolling moments, however, the __________ can also produce rolling moments
  6. Weight and balance of airplanes is important because
  7. A “neutral” aircraft wing design is one where the
  8. The condition(s) of flight that can be critical to the directional control forces exerted by the rudder is/are
  9. If an aircraft is disturbed from its equilibrium position and has the tendency neither to return nor to move farther away from its equilibrium position, is demonstrating
  10. In Transonic, Supersonic, and Hypersonic flight the air is considered to be
  11. As the airflow passes over the airfoil, its speed increases and, somewhere on the surface of the airfoil, its speed reaches a maximum value of Mach 1 before completely passing over the airfoil and returning to its freestream airspeed. The airspeed that the aircraft is flying when this condition occurs is
  12. The desired combination of static and dynamic stability for an aircraft design is
  13. The Airplane Flying Handbook describes Shallow Turns (<20 of bank) as those in which the bank is so shallow that the inherent lateral stability of the airplane is
  14. If an aircraft that is trimmed for non-sideslip flight is subjected to a sideslip condition (i.e., crosswind) and does not react to the new relative wind is said to have
  15. The upward inclination of a wing or horizontal stabilizer to the horizontal plane is referred to as
  16. In general, a sweepback wing produces a stabilizing effect on the vertical axis (i.e., yaw)
  17. If an aircraft that has been disturbed from its equilibrium position has the initial tendency to move farther away from its equilibrium position, it is demonstrating
  18. An Oblique shock wave will have what effect on velocity and Mach number?
  19. Aircraft speeds where the airflow around the aircraft is above Mach 5.0 is
  20. If an aircraft is rolled into a given bank, released, and remains at that bank angle demonstrates
  21. A high wing position (i.e., a Cessna aircraft) places the CG of an airplane __________ the center of pressure of the wing.
  22. The downward inclination of a wing or horizontal stabilizer to the horizontal plane is referred to as
  23. Wing dihedral is primarily used on low wing aircraft for the purpose of offsetting the AOA between the wing and relative wind resulting in a stabilized rolling moment.
  24. If an aircraft that is trimmed for non-sideslip flight is subjected to a sideslip condition (i.e., crosswind) and then reacts by turning away from the new relative wind, thus increasing the sideslip angle, is said to have
  25. The speed of sound in air is a function of _____________ alone.
  26. The Airplane Flying Handbook describes Medium Turns (20 to 45 of bank) as those in which the angle of bank remains nearly constant. This type of turn demonstrates
  27. The first aircraft to be designed, produced and flown with an aerodynamically unstable design was the
  28. If an aircraft is rolled into a given bank, released, and rolls back to zero bank by itself demonstrates
  29. The factor(s) most influential on the directional stability of an aircraft is/are
  30. An Expansion wave will have what effect on velocity and Mach number?
