Question 1

What is a likely consequence of low outside temperature?

Accepted Answer

true altitude may be lower than indicated altitude.

Answer

The altimeter automatically resets to standard pressure.

Answer

The aircraft becomes exempt from maintenance requirements.

Answer

The transponder changes to emergency code automatically.

Question 2

Fuel quantity in small aircraft is most commonly measured through a level sensor. The European Certification Specifications CS 23 require that...

Accepted Answer

A fuel quantity indicator must be available for each tank and the indicator must be calibrated to read "zero" during level flight when the quantity of fuel remaining in the tank is equal to the unusable fuel supply.

Answer

At least one fuel quantity indicator must be available to indicate the total amount of fuel abord an aircraft. This Indicator must be calibrated adequately to indicate the correct amount of fuel during all phases of flight.

Answer

If the fuel indicator fails, the pilot must land at the next available airport.

Answer

If no fuel quantity indicator is available to the pilot in flight, the pilot must check the fuel quantity before commencing the flight and recalculate the remaining fuel on board in regular intervals during the flight.

Question 3

When using direct current, electrically driven flight instruments are marked with...

Accepted Answer

"DC".

Answer

"AL".

Answer

"CO".

Answer

"EL".

Question 4

Where does a geometrically twisted rotor blade have its largest pitch angle?

Accepted Answer

Next to the rotor blade roots

Answer

Between rotor blade tips and rotor blade roots

Answer

In the entire area of the rotor blade

Answer

Next to the rotor blade tips

Question 5

Which statement about carburettor icing is correct?

Accepted Answer

It can occur even when the outside air temperature is above freezing.

Answer

It occurs only below -20°C.

Answer

It is impossible in humid air.

Answer

It increases engine power.

Question 6

Which value can the pilot derive from the tachometre?

Accepted Answer

Crankshaft or main rotor revolutions per minute

Answer

Airspeed of the helicopter

Answer

Vertical speed of the helicopter

Answer

Engine performance and rotor performance

Question 7

What does the dynamic pressure depend directly on?

Accepted Answer

Air density and airflow speed squared

Answer

Lift- and drag coefficient

Answer

Air pressure and air temperature

Answer

Air density and lift coefficient

Question 8

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 9

A spider control...

Accepted Answer

Changes the pitch angle of the rotor blades via an internal control rod.

Answer

Feeds fuel by the rotational movement of pistons with various lengths.

Answer

Prevents the overlay of collective and periodic control inputs on the main rotor.

Answer

Changes the ignition timing of the magneto ignition during start-up.

Question 10

The connection between the main rotor mast and the main rotor head is...

Accepted Answer

Screwed.

Answer

Welded.

Answer

Pressed.

Answer

Glued.
