    attack

    direction of the relative wind
  5. 3201-1. Which statement relates to Bernoulli's principle?
    Air traveling faster over the curved upper survace of an airfoil causes lower pressure on the top surface.
  6. 3201. The four forces acting on an airplane in flight are ___
    lift, weight, thrust, and drag
  7. 3213. What is the purpose of the rudder on an airplane?
    To control yaw
  8. 3205. What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight?
    lift equals weight, and thrust equals drag
  9. 3202. When are the four forces that act on an airplane in equilibrium?
    During unaccelerated flight.
  10. 3210. An airplane said to be inherently stable will ___
    require less effort to control
  11. 3211. What determines the longitudinal stability of an airplane?
    The location of the CG with respect to the center of lift.
  12. 3212. What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?
    The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.
  13. 3287. An airplaine has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be ___
    difficulty in recovering from a stalled condition.
  14. 3288. Loading an airplane to the most aft CG will cause the airplane to be ___
    less stable at all speeds.
  15. 3211-1. Changes in the center of pressure of a wing affect the aircraft's ___
    aerodynamic balance and controllability
  16. 3214. (Refer to Figure 2.) If an airplane weights 2300 pounds, what approximate weight would the airplaine structure be required to support during a 60 degree banked turn while maintaining altitude?
    4600 pounds
  17. 3215. (Refer to Figure 2.) If an airplane weights 3300 pounds, what approximate weight would the airplaine structure be required to support during a 30 degree banked turn while maintaining altitude?
    3960 pounds
  18. 3216. (Refer to Figure 2.) If an airplane weights 4500 pounds, what approximate weight would the airplaine structure be required to support during a 45 degree banked turn while maintaining altitude?
    6750 pounds
  19. 3217. The amount of excess load that can be imposed on the wing of an airplane depends on the ___
    speed of the airplane
  20. 3218. Which basic flight maneuver increases the load factor on an airplane as compared to straight-and-level flight?
    Turns
  21. 3301. What forces makes an airplane turn?
    The horizontal component of lift.
  22. 3316. During an approach to a stall, an increased load factor will cause the airplane to ___
    stall at a higher airspeed
  23. 3202-1. Select the four flight fundamentals involved in maneuvering an aircraft.
    Straight-and-level turns, turns, climbs, and descents
  24. 3202-2. (Refer to Figure 63.) In flying the rectangular course, when would the aircraft be turned less than 90 degrees?
    Corners 1 and 4
  25. 3202-3. (Refer to Figure 67.) While practicing S-turns, a consistently smaller half-circle is made on one side of the road than on the other, and this turn is not completed before crossing the road or reference line. This would most likely occur in turn ___
    4-5-6 because the bank is increased too rapidly during the early part of the turn.
  26. 3202-04. If an emergency situation requires a downwind landing, pilots should expect a faster ___
    groundspeed at touchdown, a longer ground roll, and the likelihood of overshooting the desired touchdown point.
  27. 3263. As altitude increases, the indicated airspeed at which a given airplanes stalls in a particular configuration will ___
    remain the same regardless of altitude.
  28. 3309. In what flight condition must an aircraft be placed in order to spin?
    Stalled.
  29. 3310. During a spin to the left, which wing(s) is/are stalled?
    Both wings are stalled.
  30. 3311. The angle of attack at which an airplane wing stalls will ___
    remain the same regardless of gross weight.
  31. 3219. One of the main functions of flaps during approach and landing is to ___
    increase the angle of descent without increasing the airspeed.
  32. 3220. What is one purpose of wing flaps?
    To enable the pilot to make steeper approaches to a landing without increasing the airspeed.
  33. 3315. Ground effect is most likely to result in which problem?
    Becoming airborne before reaching recommended takeoff speed.
  34. 3312. What is ground effect?
    The result of the interference of the surface of the Earth with the airflow patterns about an airplane.
  35. 3313. Floating caused by the phenomenon of ground effect will be most realized during an approach to land when at ___
    less than the length of the wingspan above the surface.
  36. 3314. What must a pilot be aware of as a result of ground effect?
    Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating.
  37. 3829. When landing behind a large aircraft, which procedure should be followed for vortex avoidance?
    Stay above its final approach flightpath all the way to touchdown.
  38. 3829-3. How does the wake turbulence vortex circulate around each wingtip?
    Outward, upward, and around each tip.
  39. 3827. When taking off or landing at an airport where heavy aircraft are operating, one should be particularly alert to the hazards of wingtip vortices because this turbulence tends to ___
    sink into the flightpath of aircraft operating below the aircraft generating the turbulence.
  40. 3824. Wingtip vortices are created only when an aircraft is ___
    developing lift.
  41. 3825. The greatest vortex strength occurs when the generating aircraft is ___
    heavy, clean, and slow
  42. 3826. Wingtip vortices created by large aircraft tend to ___
    sink below the aircraft generating turbulence.
  43. 3828. The wind condition that requires maximum caution when avoiding wake turbulence on a landing is a ___
    light, quartering tailwind.
  44. 3829. When landing behind a large aircraft, the pilot should avoid wake turbulence by staying ___
    above the large aircraft's final approach path and landing beyond the large aircraft's touchdown point.
  45. 3830. When departing behind a heavy aircraft, the pilot should avoid wake turbulence by maneuvering the aircraft ___
    above and upwind from the heavy aircraft.
