POF 51-100

Left rudder pedal input will cause a:

• left yaw about the vertical axis and left roll about the longitudinal axis.

• right yaw about the vertical axis and right roll about the longitudinal axis.

• left yaw about the vertical axis and right roll about the longitudinal axis.

• right yaw about the vertical axis and left roll about the longitudinal axis.

Which of these statements are correct or incorrect regarding a sideslip, with the elative airflow coming from the right, on an aeroplane that exhibits both directional and lateral stability? 1) The initial tendency of the nose of the aeroplane is to move to the right. 2) The initial tendency of the left wing is to move down.

• 1) is correct, 2) is correct.

• 1) is incorrect, 2) is correct.

• 1) is incorrect, 2) is incorrect

• 1) is correct, 2) is incorrect.

For a fixed-pitch propeller in flight at a given TAS, the blade angle of attack will:

• remain constant if RPM increases.

• increase if RPM decreases.

• decrease if RPM decreases.

• remain constant if RPM decreases.

MMO can be exceeded in a climb at a constant lAS because:

• maintaining a constant lAS requires an increase in TAS.

• as altitude increases the local speed of sound increases.

• at reduced density the Mach meter will under read.

• position error increases.

What changes in aircraft control must be made to maintain altitude while the airspeed is being decreased?

• Increase the angle of attack to compensate for the decreasing lift

• Increase the angle of attack to produce more lift than drag.

• Decrease the angle of attack to compensate for the increasing drag.

• Maintain a constant angle of attack until the desired airspeed is reached, then increase the angle of attack.

Which statement, about an aeroplane leaving ground effect at constant angle of attack, is correct? 1) The lift coefficient CL increases. 2) The induced drag coefficient CDi decreases.

• 1) is correct, 2) is incorrect.

• 1) is incorrect, 2) is incorrect

• 1) is correct, 2) is correct.

• 1) is incorrect, 2) is correct.

Which aeroplane behaviour will be corrected by a yaw damper?

• Spiral dive.

• Tuck under.

• Dutch roll.

• Buffeting.

Which of these statements about flutter are correct or incorrect? 1) Wing mounted engines extending ahead of the wing contribute to wing flutter suppression. 2) Excessive free play or backlash increases the speed at which control surface flutter occurs.

• 1) is incorrect, 2) is correct.

• 1) is incorrect, 2) is incorrect.

• 1) is correct, 2) is incorrect.

• 1) is correct, 2) is correct.
