  4. When a shock-induced separation occurs behind the normal shock wave, rather than at the trailing edge of the wing, the center of pressure shifts ________ and produces a _________ pitching moment.
  5. Force divergence occurs at airspeeds around ______ above Mcrit.
  6. Another name for asymmetrical loading, which of the following occurs when the downward moving blade of a propeller engine creates more lift than the upward moving blade?
  7. If an aircraft that has been disturbed from its equilibrium position has the initial tendency to return to it’s original equilibrium position, it is demonstrating

  14. A Normal shock wave will have what effect on velocity and Mach number?
  15. Con corner exists when an airplane’s stall speed in Mach number is equal to the MMO.

  17. During calm wind conditions, in helicopters with American rotation, which of these flight operations would require the most power?
  18. Which of the following are not design features for high subsonic flight?
  19. 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

  21. Consider a small, twin-engine general aviation airplane with a datum line located near the windshield of the aircraft. If a 25-lb bag was removed from the rear baggage compartment, what overall effect would the movement have on aircraft weight and balance?
  22. What action should you take if engine failure occurs at altitude?
  23. On an aircraft with inboard and outboard ailerons, the inbound spoilers are locked at high speeds to prevent wing twisting or bending.
  24. The downward inclination of a wing or horizontal stabilizer to the horizontal plane is referred to as
  25. On many light, multi-engine aircraft airspeed indicators, VMC may be marked by a __________ radial line.
  26. Vortex generators mix lower kinetic energy air from outside the boundary layer with the faster air in the boundary layer and delay separation.
  27. High airspeeds, particularly in turbulent air, should be avoided primarily because of the possibility of:
  28. The local Mach number on top of the wing is always greater than the flight Mach number.
