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

Question 1

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 2

Which statement about ground effect is correct?

Accepted Answer

It reduces induced flow and power required when hovering close to the surface.

Answer

It increases power required compared with OGE hover.

Answer

It is strongest at high altitude cruise.

Answer

It affects only fixed-wing aircraft.

Question 3

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 4

Which energies serve to maintain the rotor rpm in an autorotation?

Accepted Answer

Potential or kinetic energy

Answer

Mechanical or chemical energy

Answer

Rotational and linear energy

Answer

Frictional and flow energy

Question 5

What happens to thrust and tangential force if the rotor RPM decreases by about 10 % in cruise flight?

Accepted Answer

The thrust and the tangential force decrease

Answer

The thrust and the tangential force increase

Answer

The thrust decreases and the tangential force remains constant

Answer

The thrust remains constant and the tangential force increases

Question 6

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 7

Which statement about flare in autorotation is correct?

Accepted Answer

It can reduce rate of descent and forward speed before touchdown.

Answer

It is used to stop the rotor immediately.

Answer

It increases sink rate in all cases.

Answer

It replaces rotor RPM control.

Question 8

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

Accepted Answer

It reduces the pilot-in-command's workload.

Answer

It increases the required control forces in all manoeuvres.

Answer

It improves control under all load factors.

Answer

It increases the maximum permitted helicopter mass.

Question 9

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 10

Which statement about the required force to change the pitch angle is correct?

Accepted Answer

It must be greater than the tangential force

Answer

It is the smallest by using an advance angle of 90°

Answer

It is the smallest by using a delta-three-hinge

Answer

It must be greater than the rotor disc loading
