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

Question 1

Why is driven region of the rotor important for a PPL(H) flight?

Accepted Answer

It consumes energy to produce lift.

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

Why is tail rotor drift important for a PPL(H) flight?

Accepted Answer

Sideways force may require cyclic correction in hover.

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 3

What can be expected during a hover flight in ground effect within a forest glade?

Accepted Answer

Recirculation of air masses and an impairment of the ground effect

Answer

Useful ground effect caused by a smaller induced airflow

Answer

No air turbulence through the slipstream and stable attitude

Answer

Aspiration of the tail rotor in the direction of the forest and a performance gain

Question 4

Why is flapping hinge function important for a PPL(H) flight?

Accepted Answer

It allows blade motion that helps balance lift in forward flight.

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 5

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 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

The effective angle of attack is the angle between...

Accepted Answer

Effective airflow and chord line

Answer

Chord line and tip path plane

Answer

Tip path plane and rotor blade

Answer

Effective airflow and tip path plane

Question 8

Which statement about LTE is correct?

Accepted Answer

Loss of tail rotor effectiveness is an uncommanded yaw condition that can occur in susceptible conditions.

Answer

It is a type of VOR radial.

Answer

It improves hover controllability.

Answer

It is prevented by ignoring wind direction.

Question 9

Why are the stability criteria of a helicopter very important?

Accepted Answer

A lack of stability may lead to loss of control

Answer

Low stability reduces the available control forces

Answer

High stability prevents low load factors

Answer

Large stability increases the maximum take-off mass

Question 10

Which statement about high gross mass is correct?

Accepted Answer

It increases power required and can reduce performance margins.

Answer

It always lowers power required.

Answer

It eliminates retreating blade stall risk.

Answer

It has no effect on hover ceiling.
