Aircraft General Knowledge - PPL(H) - Private Pilot Licence (Helicopter)

Question 1

A steel or lead rotor blade spar...

Accepted Answer

Improves the autorotation characteristics by increased inertia.

Answer

Prevents high-frequency vibrations to the main rotor system.

Answer

Is necessary for the connection to the main rotor head.

Answer

Holds loads of the uniform lift distribution.

Question 2

In which way may an altimeter subscale which is set to an incorrect QNH lead to an incorrect altimeter reading?

Accepted Answer

If the subscale is set to a higher than actual pressure, the indication is too high. This may lead to much closer proximity to the ground than intended

Answer

If the subscale is set to a lower than actual pressure, the indication is too high. This may lead to much closer proximity to the ground than intended

Answer

If the subscale is set to a lower than actual pressure, the indication is too low. This may lead to much closer proximity to the ground than intended

Answer

If the subscale is set to a higher than actual pressure, the indication is too low. This may lead to much greater heights above the ground than intended

Question 3

Which statement about the swashplate is correct?

Accepted Answer

It transmits cyclic and collective pitch inputs to the rotating rotor system.

Answer

It stores hydraulic fluid.

Answer

It measures exhaust gas temperature.

Answer

It locks the rotor blades during start.

Question 4

Why is door and latch security important for a PPL(H) flight?

Accepted Answer

It prevents distraction and possible damage in 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

An attitude director indicator (ADI) combines the information provided by...

Accepted Answer

The attitude indicator and the flight director.

Answer

The attitude indicator and the relative bearing indicator.

Answer

The directional gyro and the rate gyro.

Answer

The attitude indicator and the radio magnetic indicator.

Question 6

The pilot wants to refuel the helicopter after a cold night early in the morning. What needs to be checked before starting the engine?

Accepted Answer

Fuel for water content and impurities

Answer

VHF communication for transmission

Answer

Carburettor heat for function

Answer

Left seat controls for damage and tight fit

Question 7

Calibrated airspeed (CAS) equals...

Accepted Answer

Indicated airspeed (IAS) corrected for instrument and position error.

Answer

Ground speed (GS) corrected for instrument and position error.

Answer

True airspeed (TAS) corrected for wind.

Answer

Equivalent airspeed (EAS) corrected for altitude.

Question 8

Which statement about the magnetic compass is correct?

Accepted Answer

It is affected by acceleration, turning and nearby magnetic fields.

Answer

It is unaffected by aircraft electrical equipment.

Answer

It measures true north directly.

Answer

It needs pitot pressure to operate.

Question 9

What is likely to be the cause if the engine runs unusually rough while checking the magnetos?

Accepted Answer

Sparking plug is defective

Answer

Short circuit on the ground cable

Answer

Ignition switch is faulty

Answer

Starter is faulty

Question 10

Which method of measurement is mostly used for the fuel supply indication on helicopters?

Accepted Answer

Capacitive measurement

Answer

Dipstick measurement

Answer

Flow measurement

Answer

Inductive measurement
