Question 1

For a VFR private pilot, what should be remembered about load factor?

Accepted Answer

It is the ratio of lift to weight and increases in manoeuvres such as level turns

Answer

It is determined only by QNH

Answer

It is runway slope

Answer

It changes aircraft registration

Question 2

In order to improve the stall characteristics of an aircraft, the wing is twisted outwards (the angle of incidence varies spanwise). This is known as...

Accepted Answer

Geometric washout

Answer

Aerodynamic washout

Answer

Arrow shape

Answer

V-form

Question 3

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 4

Which statement gives the best operational interpretation of parasite drag?

Accepted Answer

It generally increases as airspeed increases

Answer

It always improves stability

Answer

It is measured in litres

Answer

It prevents every stall

Question 5

Which practical rule applies to flaps?

Accepted Answer

They increase lift and drag and change pitching moments

Answer

It is a runway lighting signal

Answer

It cancels drag

Answer

It affects only passengers

Question 6

Rotation around the vertical axis is called...

Accepted Answer

Yawing

Answer

Rolling

Answer

Pitching

Answer

Slipping

Question 7

What types of boundary layers can be found on an aerofoil?

Accepted Answer

Laminar layer at the leading wing areas, turbulent boundary layer at the trailing areas

Answer

Turbulent boundary layer along the complete upper surface with separated airflow

Answer

Turbulent layer at the leading wing areas, laminar boundary layer at the trailing areas

Answer

Laminar boundary layer along the complete upper surface with non-separated airflow

Question 8

Stall speed in level flight is 50 kt. What is the approximate stall speed in a level 60° banked turn?

Accepted Answer

71 kt

Answer

50 kt

Answer

81 kt

Answer

61 kt

Question 9

What is the advantage of differential aileron movement?

Accepted Answer

The drag of the downwards deflected aileron is lowered and the adverse yaw is smaller

Answer

The ratio of the drag coefficient to lift coefficient is increased

Answer

The adverse yaw is higher

Answer

The total lift remains constant during aileron deflection

Question 10

Which statement is correct for stall?

Accepted Answer

A stall occurs when the critical angle of attack is exceeded

Answer

It removes the need for aircraft control

Answer

It always improves stability

Answer

It replaces trim
