Question 1

What is the advantage of a pushing tail rotor over a pulling tail rotor?

Accepted Answer

Less thrust loss by free outflow of the accelerated air mass

Answer

Gain of thrust by Coanda and Magnus effect due to the airflow around the tail boom

Answer

Effective airflow of tail rotor blades by using the downwash

Answer

Self-compensating anti-torque operation by using the downwash

Question 2

What might be the reason for scratches on the tail stringer?

Accepted Answer

Contact with ground

Answer

Old colour

Answer

Intense erosion

Answer

Rotor blade contact

Accepted Answer

At an angle of 90° to the force being applied.

Answer

At an angle of 45° to the force being applied.

Answer

In a northern direction.

Answer

At an angle of 180° to the force being applied.

Question 5

What difference in altitude is shown by an altimeter, if the reference pressure scale setting is changed from 1000 hPa to 1010 hPa?

Accepted Answer

80 m more than before

Answer

Values depending on QNH

Answer

Zero

Answer

80 m less than before

Question 6

Why are all the connecting flanges of the main shaft designed flexible?

Accepted Answer

To compensate for thermal stresses and installation errors

Answer

For the distribution of pressure and tensile forces

Answer

To have a predetermined breaking point for engine damage

Answer

For the frictional connection to the main rotor gearbox

Question 7

Which actions shall be taken if the engine oil pressure continuously drops to zero?

Accepted Answer

Land immediately on suitable terrain and be prepared for an autorotation

Answer

Check the mixture lever and enrich the mixture

Answer

Reduce engine performance and continue the flight to the destination

Answer

Monitor oil temperature and land at the nearest airfield

Question 8

The sandwich structure consists of two...

Accepted Answer

Thin layers and a light core material.

Answer

Thick layers and a light core material.

Answer

Thin layers and a heavy core material.

Answer

Thick layers and a heavy core material.

Question 9

When is it necessary to adjust the pressure in the reference scale of an alitimeter?

Accepted Answer

Before every flight and during cross country flights

Answer

After maintance has been finished

Answer

Once a month before flight operation

Answer

Every day before the first flight

Question 10

Which is the purpose of the altimeter subscale?

Accepted Answer

To reference the altimeter reading to a predetermined level such as mean sea level, aerodrome level or pressure level 1013.25 hPa

Answer

To set the reference level for the altitude decoder of the transponder

Answer

To adjust the altimeter reading for non-standard temperature

Answer

To correct the altimeter reading for system errors
