CPL POF 4

The weight of an object:

• Is always equal to its mass

• Is the product of its mass multiplied by the acceleration of gravity

• Is the product of its mass multiplied by its velocity

• Depends only on the force of gravity

Which of the following does NOT have a positive effect on lateral stability?

• Dihedral

• Sweepback

• High wing / low C of G

• Anhedral

In the lift formula (L=CL1/2pV2s), the term '1/2pV2' can be taken to stand for"

• Indicated airspeed

• Static pressure

• True airspeed

• Angle of Attack

Which of the following statements correctly describes adverse yaw?

• Yaw in the same direction of the turn, which is a secondary effect of roll

• The yaw which is required to align the aircraft with the runway just before touchdown

• The yaw resulting from asymmetric thrust after failure of a wing mounted engine

• Yaw in the opposite direction direction of turn, which is caused by aileron drag.

The airspeed for the maximum rate of climb (Vy) is the airspeed at which:

• There is the greatest excess thrust available over drag

• The aeroplane can just be maintained safely in the climb with maximum power set

• The best climb gradient can be maintained

• There is the greatest excess of power available over power required.

Two identical aircraft are turning at the same IAS and at 30 degrees AoB, but one aircraft is at a much higher altitude than the other. Which of the following statements is correct?

• Both aircraft have the same rate and radius of turn

• The higher aircraft has a higher rate of turn, and is turning on a greater radius

• The high aircraft has a lower rate of turn, and is turning on a greater radius

• The high aircraft has a higher rate of turn, and is turning in a smaller radius

For a propeller which rotates clockwise when viewed from the rear, asymmetric blade effect results in a shift of the thrust line to the ____ of the propeller disc.

• Left

• Right

• Top

• Bottom

Your A/C has a RPM of 2500 and a manifold pressure of 30Hg. You wish to set 2300 RPM and 28 Hg the correct sequence to achieve this would be?

• Decrease throttle then decrease RPM

• Decrease RPM then decrease manifold pressure

• It doesn't matter either way

• Both at the same time

In a venturi, increase in speed will cause

• Decrease in Dynamic pressure and an increase in static pressure

• Increase in dynamic pressure and increase in static pressure

• Decrease in dynamic pressure and decrease in static pressure

• Increase in dynamic pressure and decrease in static pressure

What is lateral stability?

• Stability about the lateral axis

• Stability about the longitudinal axis

• Stability about the normal axis

• Stability in pitch
