Principles of Flight (Helicopter) - PPL(H) - Private Pilot Licence (Helicopter)

Question 1

The reason for a stall at a given pitch angle can be...

Accepted Answer

Smaller vertical airflow through the rotor and constant peripheral speed

Answer

Constant peripheral speed and great vertical airflow through the rotor

Answer

Smaller effective angle of attack and small peripheral speed

Answer

Smaller frontal resistance and turbulent airflow

Question 2

Which statement about cyclic pitch is correct?

Accepted Answer

It tilts the rotor disc to control movement around pitch and roll axes.

Answer

It changes all blade pitch equally.

Answer

It controls fuel flow only.

Answer

It is used only after shutdown.

Question 3

Which action best supports safe management of stall region in autorotation?

Accepted Answer

Avoid excessive collective that expands the stall region.

Answer

Delay the decision until after take-off.

Answer

Use the item only if requested by passengers.

Answer

Ignore it when the helicopter has sufficient fuel.

Question 4

What is the usual trade-off when helicopter stability is increased?

Accepted Answer

Reduced manoeuvrability and controllability.

Answer

A decrease in general aviation safety.

Answer

An increase in maximum permitted helicopter mass.

Answer

Improved control under negative load factors.

Question 5

What action has no effect on the rotor RPM in an autorotation?

Accepted Answer

Utilisation of friction brake.

Answer

Centre of gravity displacement.

Answer

Pitch angle change.

Answer

Transition into a turning flight.

Question 6

Which statement about settling with power is correct?

Accepted Answer

It is associated with vortex ring state conditions.

Answer

It means the engine has failed completely.

Answer

It is caused by excessive QNH.

Answer

It improves climb performance.

Question 7

Why is effective translational lift important for a PPL(H) flight?

Accepted Answer

It improves rotor efficiency as airflow becomes more horizontal and less recirculated.

Answer

It is relevant only to airline transport operations.

Answer

It can be ignored when the flight remains local.

Answer

It is replaced by passenger preference.

Question 8

What aerodynamic effect is most relevant? A strong left crosswind affects a helicopter susceptible to LTE.

Accepted Answer

yaw control margin may be reduced.

Answer

The altimeter setting becomes invalid.

Answer

The magnetic compass becomes the primary lift source.

Answer

The aircraft mass automatically decreases.

Question 9

What shape of a rotor blade has a positive impact on the lift distribution?

Accepted Answer

Double trapezoidal rotor blade with a radius at the blade tip

Answer

Rectangular blade with a geometric setting of 1°

Answer

Trapezoidal blade without radius at the blade tip

Answer

Rectangular trapezoidal blade with no aerodynamic twist

Question 10

What aerodynamic effect is most relevant? The helicopter descends vertically with power and low airspeed.

Accepted Answer

vortex ring state risk may increase.

Answer

The altimeter setting becomes invalid.

Answer

The magnetic compass becomes the primary lift source.

Answer

The aircraft mass automatically decreases.
