Question 1

The empty weight and the corresponding center of gravity (CG) of an aircraft are initially determined...

Accepted Answer

By weighing.

Answer

Through data provided by the aircraft manufacturer.

Answer

For one aircraft of a type only, since all aircraft of the same type have the same mass and CG position.

Answer

By calculation.

Question 2

The term "datum" with regard to a mass and balance calculation defines...

Accepted Answer

The point on the longitudinal axis of an aeroplane or its extension from which the centers of gravity of all masses are referenced.

Answer

The distance from the reference plane to the center of gravity of an aircraft.

Answer

The point on the vertical axis of an aeroplane or its extension from which the centers of gravity of all masses are referenced.

Answer

The point on the lateral axis of an aeroplane or its extension from which the centers of gravity of all masses are referenced.

Question 3

Loads must be adequately secured in order to...

Accepted Answer

Avoid any centre of gravity (C.G.) movements.

Answer

Allow steep turns.

Answer

Prevent excessive 'g'-loading during the landing flare.

Answer

Carry extra fuel.

Question 4

Considering the following fuel data, how much trip fuel is required? Fuel for start-up and taxi: 5 L Fuel for take-off and climb: 12 L Fuel for cruise flight: 25 L Fuel for descent, approach and landing: 7 L Fuel for taxi and parking: 3 L Fuel to alternate: 13 L Final reserve fuel: 10 L

Accepted Answer

44 L

Answer

75 L

Answer

Question 6

The power output of a piston engine is limited by...

Accepted Answer

Main rotor gearbox.

Answer

Exhaust system.

Answer

Crankcase.

Answer

Centrifugal clutch.

Question 7

What is the maximum pressure altitude to conduct a hover in ground effect if the helicopter mass equals 2400 lbs and the outside air temperature is +20° C? See annex (PFP-045)

Accepted Answer

8600 ft

Answer

9000 ft

Answer

11000 ft

Answer

9500 ft

Question 8

Calculated take-off mass = 1082 kg, calculated CG = 0.254 m, fuel burn = 55 l on station 0.40 m. Where is the CG situated after the landing?

Accepted Answer

24.8 cm

Answer

25.2 cm

Answer

24.6 cm

Answer

25.4 cm

Question 9

Which is the most recently determined empty mass and the associated center of gravity (CG) arm from the aircraft documentation? See annex (PFP-006)

Accepted Answer

498 kg; 280.59 m

Answer

512 kg; 285.39 m

Answer

4 kg; 1.1 m

Answer

5 kg; 1.3 m

Question 10

Why does the VNE decrease with increasing pressure altitude?

Accepted Answer

The true airspeed (TAS) increases

Answer

The groundspeed (GS) decreases

Answer

The rotor thrust exceeds the permissible structure limitations

Answer

The tail rotor effectiveness does not provide directional stability
