FAA Private Pilot Exam 2

Question 1

The left turning tendency of an airplane caused by P-factor is the result of the

Accepted Answer

propeller blade descending on the right producing more thrust than the ascending blade on the left

Answer

P-factor, or asymmetric thrust, occurs when the propeller disk is tilted relative to the relative wind, such as during a climb. For a clockwise rotating propeller, the descending blade on the right has a higher effective angle of attack than the ascending blade on the left. This difference in angle of attack causes the right blade to produce more thrust, resulting in a yawing moment to the left.

Question 2

What is an important airspeed limitation that is not color coded on airspeed indicators?

Accepted Answer

Maneuvering speed.

Answer

Maneuvering speed (Va) is a critical airspeed limitation that is not color-coded on the airspeed indicator. It represents the maximum speed at which full or abrupt control inputs can be made without exceeding the aircraft's structural limits. Pilots must consult the aircraft's Pilot's Operating Handbook (POH) or Aircraft Flight Manual (AFM) for this specific speed.

Question 3

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

Accepted Answer

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

Answer

Even a thin layer of frost significantly roughens the wing's surface, disrupting the smooth laminar airflow essential for lift generation. This disruption drastically reduces the wing's ability to produce lift and increases drag. Consequently, the aircraft may struggle to achieve takeoff speed or maintain flight, posing a serious safety hazard.

Question 4

What is the full flap operating range for the airplane?

Accepted Answer

55 to 100 KTS.

Answer

The white arc on an airspeed indicator denotes the full flap operating range, from the power-off stall speed with flaps extended (Vso) to the maximum flap extended speed (Vfe). For this specific question, the range of 55 to 100 KTS falls within a typical white arc, indicating the safe operating speeds for flap deployment.

Question 5

The four forces acting on an airplane in flight are

Accepted Answer

lift, weight, thrust, and drag.

Answer

The four fundamental forces acting on an airplane in flight are lift, weight, thrust, and drag. Lift is the upward force opposing weight, and thrust is the forward force opposing drag. The interaction and balance of these forces determine the aircraft's flight path and performance.
