Private Pilot : 2007年 Airman Knowledge Test Question (Written Exam)
What force makes an airplane turn?
A) The horizontal component of lift.
B) The vertical component of lift.
C) Centrifugal force.
VFR approaches to land at night should be accomplished
A) at a higher airspeed.
B) with a steeper descent.
C) the same as during daytime.
In what flight condition is torque effect the greatest in a single-engine airplane?
A) Low airspeed, high power, high angle of attack.
B) Low airspeed, low power, low angle of attack.
C) High airspeed, high power, high angle of attack.
The left turning tendency of an airplane caused by P-factor is the result of the
A) clockwise rotation of the engine and the propeller turning the airplane counter-clockwise.
B) propeller blade descending on the right, producing more thrust than the ascending blade on the left.
C) gyroscopic forces applied to the rotating propeller blades acting 90° in advance of the point the force was applied.
When does P-factor cause the airplane to yaw to the left?
A) When at low angles of attack.
B) When at high angles of attack.
C) When at high airspeeds.
What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?
A) The CG shifts forward when thrust and drag are reduced.
B) The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced.
C) When thrust is reduced to less than weight, lift is also reduced and the wings can no longer support the weight.
What determines the longitudinal stability of an airplane?
A) The location of the CG with respect to the center of lift.
B) The effectiveness of the horizontal stabilizer, rudder, and rudder trim tab.
C) The relationship of thrust and lift to weight and drag.
An airplane said to be inherently stable will
A) be difficult to stall.
B) require less effort to control.
C) not spin.
In what flight condition must an aircraft be placed in order to spin?
A) Partially stalled with one wing low.
B) In a steep diving spiral.
During a spin to the left, which wing(s) is/are stalled?
A) Both wings are stalled.
B) Neither wing is stalled.
C) Only the left wing is stalled.
