Question 1

Which statement gives the best operational interpretation of load factor?

Accepted Answer

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

Answer

It is runway slope

Answer

It removes the need for aircraft control

Answer

It always improves stability

Question 2

Pressure drag, interference drag and friction drag belong to the group of the...

Accepted Answer

Parasite drag

Answer

Induced drag

Answer

Main resistance

Answer

Total drag

Question 3

During cross-country planning, which statement is correct for ground effect?

Accepted Answer

It reduces induced drag close to the ground and can affect landing and take-off behaviour

Answer

It increases induced drag greatly

Answer

It is a radio navigation effect

Answer

It applies only on the ground

Question 4

Extending flaps usually...

Accepted Answer

decreases stall speed

Answer

increases stall speed

Answer

has no effect on lift

Answer

reduces drag only

Question 5

Which principle of flight statement is correct? The fin contributes mainly to...

Accepted Answer

directional stability

Answer

It removes the need for aircraft control

Answer

It is measured in litres

Answer

It cancels drag

Question 6

What pattern can be found at the stagnation point?

Accepted Answer

Streamlines are divided into airflow above and below the profile

Answer

The boundary layer starts separating on the upper surface of the profile

Answer

The laminar boundary layer changes into a turbulent boundary layer

Answer

All aerodynamic forces can be considered as attacking at this single point

Question 7

Which factor can be changed by deploying flaps for landing?

Accepted Answer

The trim condition

Answer

The position of the centre of gravity

Answer

The effectiveness of the ailerons

Answer

The twist effect of the engine

Question 8

The ratio of span and mean chord length is referred to as...

Accepted Answer

Aspect ratio.

Answer

Trapezium shape.

Answer

Tapering.

Answer

Wing sweep.

Question 9

Which principle of flight statement is correct? Extending flaps usually...

Accepted Answer

decreases stall speed

Answer

It cancels drag

Answer

It affects only passengers

Answer

increases stall speed

Question 10

Which practical rule applies to stall?

Accepted Answer

A stall occurs when the critical angle of attack is exceeded

Answer

It is unrelated to angle of attack

Answer

It replaces trim

Answer

It is a runway lighting signal
