You are flying on an easterly course. If the wind is from the northeast, you must crab the airplane:

Somewhat to the north of east to counteract drift.

South of east to counteract drift.

North to counteract torque.

(Refer to Figure 26.) In flight and approaching the Bryn (Pvt) Airstrip (area 2) the weather minimums are

What measurement can be used to determine the stability of the atmosphere?

Actual lapse rate.

Surface temperature.

Atmospheric pressure.

A stable air mass is most likely to have which characteristic?

Turbulent air.

How will frost on the wings of an airplane affect takeoff performance?

Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability.

Frost will change the camber of the wing, increasing its lifting capability.

Frost will cause the airplane to become airborne with a higher angle of attack, decreasing the stall speed.

A pilot should be able to overcome the symptoms or avoid future occurrences of hyperventilation by

increasing the breathing rate in order to increase lung ventilation.

closely monitoring the flight instruments to control the airplane.

Except when necessary for takeoff or landing, what is the minimum safe altitude required for a pilot to operate an aircraft over congested areas?

An altitude of 500 feet above the highest obstacle within a horizontal radius of 1,000 feet of the aircraft.

An altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.

An altitude of 1,000 feet above any person, vessel, vehicle, or structure.

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.

Wingtip vortices increase creating wake turbulence problems for arriving and departing aircraft.

A full stall landing will require less up elevator deflection than would a full stall when done free of ground effect.
