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

Question 1

Why is blade pitch increase important for a PPL(H) flight?

Accepted Answer

It increases angle of attack and power required.

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 2

What aerodynamic effect is most relevant? The pilot raises collective rapidly.

Accepted Answer

torque and power required increase.

Answer

The altimeter setting becomes invalid.

Answer

The magnetic compass becomes the primary lift source.

Answer

The aircraft mass automatically decreases.

Question 3

Which statement about coning is correct?

Accepted Answer

It is the upward bending of rotor blades due to lift and centrifugal force balance.

Answer

It is a radio navigation procedure.

Answer

It is caused by altimeter error.

Answer

It is the same as tail rotor drift.

Question 4

The effective airflow velocity of a rotor blade element varies with the distance from the rotor shaft axis, because the...

Accepted Answer

Peripheral speed increases if the displacement to the rotor blade tip decreases

Answer

Helicopter airframe disturbs the airflow

Answer

Tangential force and airflow reversal vary

Answer

Drag force in direction of the rotation axis is increased

Question 5

What is the main safety effect of increased stability in a helicopter?

Accepted Answer

It improves general flight safety.

Answer

It increases the maximum permitted helicopter mass.

Answer

It improves control under negative load factors.

Answer

It always reduces the required control forces.

Question 6

The drive system of the autogyro's main rotor is based on...

Accepted Answer

The speed of the airflow.

Answer

A fan in the cabin.

Answer

An engine in the cabin.

Answer

An engine at the rotor blade tip

Question 7

Vy is the speed...

Accepted Answer

For the best rate of climb

Answer

To rotate

Answer

For the best angle of climb

Answer

Never to be exceeded

Question 8

Which of the following options has an effect on the autorotation characteristics?

Accepted Answer

Helicopter mass and density altitude

Answer

Smoothly working tail rotor control and low RPM warning systems

Answer

Air temperature and wind speed

Answer

Pressure altitude and wind speed

Question 9

Which action best supports safe management of tip-path plane?

Accepted Answer

Use cyclic to tilt it for control.

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 10

Which statement about vortex ring state is correct?

Accepted Answer

It can occur with high rate of descent, low forward speed and power applied.

Answer

It occurs only with the engine stopped.

Answer

It is prevented by increasing collective indefinitely.

Answer

It is a compass turning error.
