Question 1

Which curve represents the induced drag? See Appendix (PFA-011)

Accepted Answer

1

Answer

4

Answer

2

Answer

3

Question 2

Which statement about lift and angle of attack is correct?

Accepted Answer

Increasing the angle of attack too far may result in a loss of lift and an airflow separation

Answer

Too large angles of attack can lead to an exponential increase in lift

Answer

Increasing the angle of attack results in less lift being generated by the aerofoil

Answer

Decreasing the angle of attack results in more drag being generated by the aerofoil

Question 3

The elevator moves an aeroplane around the...

Accepted Answer

Lateral axis.

Answer

Elevator axis.

Answer

Longitudinal axis.

Answer

Vertical axis.

Question 4

How do lift and drag change when setting flaps to a lower position?

Accepted Answer

Lift increases, drag increases

Answer

Lift increases, drag decreases

Answer

Lift decreases, drag decreases

Answer

Lift decreases, drag increases

Question 5

The change in pitch at a propeller blade from the root to the tip ensures...

Accepted Answer

A nearly constant load by a constant effective angle of attack over the entire length of the blade

Answer

That the most thrust is produced at the blade tip

Answer

That the most thrust is produced at the blade root

Answer

The largest possible angle of attack at the blade tip

Question 6

Rudder deflections result in a turn of the aeroplane around the...

Accepted Answer

Vertical axis.

Answer

Rudder axis.

Answer

Lateral axis.

Answer

Longitudinal axis.

Question 7

The right aileron deflects upwards, the left downwards. How does the aircraft react?

Accepted Answer

Rolling to the right, yawing to the left

Answer

Rolling to the left, no yawing

Answer

Rolling to the right, yawing to the right

Answer

Rolling to the left, yawing to the right

Question 8

What structural item provides lateral stability to an airplane?

Accepted Answer

Wing dihedral

Answer

Differential aileron deflection

Answer

Vertical tail

Answer

Elevator

Question 9

Flying with speeds higher than the never-exceed-speed (vNE) may result in...

Accepted Answer

Flutter and mechanically damaging the wings.

Answer

Too high total pressure resulting in an unusable airspeed indicator.

Answer

An increased lift-to-drag ratio and a better glide angle.

Answer

Reduced drag with increased control forces

Question 10

"Longitudinal stability" is referred to as stability around which axis?

Accepted Answer

Lateral axis

Answer

Propeller axis

Answer

Vertical axis

Answer

Longitudinal axis
