1.9: Turning Tendencies

Question 1

In what flight condition are torque effects more pronounced 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.

Answer 1

Low airspeed, high power, high angle of attack.

Question 2

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 counterclockwise.
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.

Answer 2

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

Question 3

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.

Answer 3

When at high angles of attack.
