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

Question 1

A delta-three hinge is used to allow...

Accepted Answer

For a decreased pitch angle at an upwards flapping blade

Answer

The advancing blade to flap up about the hinge

Answer

The advancing blade to lead about the hinge

Answer

The advancing blade to drag about the hinge

Question 2

Which ratio corresponds to the rotor disc loading?

Accepted Answer

Helicopter mass / rotor disc

Answer

Rotor disc / helicopter mass

Answer

Rotor thrust / rotor disc

Answer

Rotor disc / rotor thrust

Question 3

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 4

Which action best supports safe management of anti-torque demand?

Accepted Answer

Anticipate pedal input when changing collective.

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 5

What is the reason for the driving forces in an autorotation?

Accepted Answer

Downward tilted effective airflow

Answer

Low rate of descent

Answer

Increased pitch angle

Answer

High airspeeds

Question 6

Why is stall region in autorotation important for a PPL(H) flight?

Accepted Answer

It produces drag and does not drive the rotor efficiently.

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 7

During an autorotation the airspeed is limited by...

Accepted Answer

The drift of the driving forces on the returning blade

Answer

The displacement of the stall regions in the inner area of the rotor blade

Answer

The interference drag during low rates of descent

Answer

The landing gear during the touchdown

Question 8

Which landing site (no wind) prevents the impairment of the ground effect?

Accepted Answer

Plain terrain

Answer

Narrow forest glade

Answer

Elevated helipad

Answer

Sloping ground

Question 9

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 10

The helicopter's stability is increased by...

Accepted Answer

Attaching a stabilizer

Answer

Reducing the rotor RPM

Answer

Pivoting the drag hinge

Answer

Decreasing the rotor mass
