32. Ground effect will enable an aeroplane to become airborne below normal flying speed primarily due to

  3. you are in the Standard Pressure Region.
  4. the barometric pressure is 29.92 in. Hg.

34. The altimeter setting is 29.70 in. Hg. If the pilot inadvertently sets 30.70 in. Hg on the altimeter subscale, the altimeter will read

  2. 1,000 ft too low.
  3. 100 ft too high.
  4. 100 ft too low.

35. A major early symptom of hypoxia is

  1. drowziness.
  2. dizziness.
  3. euphoria.
  4. hyperventilation.

36. If you are looking at a featureless sky during hazy or dark conditions, your eyes will tend to focus at a point approximately . . . . . ft away.

  1. 3 to 5
  2. 30 to 50
  3. 300 to 500
  4. 3,000 to 5,000

37. The effects of one drink of alcohol at sea level will

  1. increase with an increase in altitude.

  3. remain the same with an increase in altitude.
  4. remain constant to 6,000 feet ASL.

38. During an approach to land on an upsloping runway, the pilot may experience the illusion that the aeroplane is . . . . . than it actually is.

  1. higher
  2. lower
  3. closer in
  4. approaching faster

39. When turning from downwind to into-wind at low altitude, a pilot may experience an illusion of

  1. slipping and decreasing airspeed.
  2. skidding and decreasing airspeed.
  3. slipping and increasing airspeed.
  4. skidding and increasing airspeed.

40. Wheelbarrowing on landing may result from a
