Question 2

Given are the following information at take-off ____________________________________________________________ STATION....................MASS (kg)....ARM (cm)....MOMENT (kgcm) ____________________________________________________________ Basic Empty Condition...12045.........+30......+361350 Crew..................................145........-160.......-23200 Freight (1)..........................570.......+200......+114000 Freight (2)..........................410..........-40.......-16400 Fuel.................................6045...........-8.......-48360 Given that the flight time is 2 h and the estimated fuel flow will be 1050 litres per h. The specific density of fuel is 0.79. The 'Freight (2)' will be dropped during flight within the scope of a rescue action. Calculate the CG position at landing.

Accepted Answer

Accepted Answer

Maximum certificated taxi (ramp) mass

Answer

Maximum regulated take-off mass

Answer

Maximum certificated take-off mass

Answer

Maximum regulated taxi (ramp) mass

Question 4

When an aircraft is stationary on the ground, its total weight will act vertically

Accepted Answer

Through its centre of gravity.

Answer

Through its centre of pressure.

Answer

Through a point defined as the datum point.

Answer

Through the main wheels of its undercarriage assembly.

Question 5

For the medium range transport aeroplane, from the loading manual, determine the maximum total volume of fuel which can be loaded into the main wing tanks. (Fuel density value 0.78)

Accepted Answer

11349 litres

Answer

11646 litres

Answer

8850 litres

Answer

5674 litres

Question 6

Which of the following is unlikely to have any effect on the position of the centre of gravity on an aeroplane in flight?

Accepted Answer

Changing the tailplane (horizontal stabiliser) incidence angle.

Answer

Normal consumption of fuel for a swept wing aeroplane.

Answer

Movement of cabin attendants going about their normal duties.

Answer

Lowering the landing gear.

Question 7

Given are:- Maximum structural take-off mass: 72 000 kg- Maximum structural landing mass: 56 000 kg- Maximum zero fuel mass: 48 000 kg- Taxi fuel: 800 kg- Trip fuel: 18 000 kg- Contingency fuel: 900 kg- Alternate fuel: 700 kg- Final reserve fuel: 2 000 kg. The actual take-off mass can never be higher than:

Accepted Answer

69 600 kg

Answer

70 400 kg

Answer

72 000 kg

Answer

74 000 kg

Question 8

With respect to aeroplane loading in the planning phase, which of the following statements is always correct? LM = Landing Mass. TOM = Take-off Mass. MTOM = Maximum Take-off Mass. ZFM = Zero Fuel Mass. MZFM = Maximum Zero Fuel Mass. DOM = Dry Operating Mass

Accepted Answer

LM = TOM - Trip Fuel

Answer

MTOM = ZFM + maximum full tank fuel mass

Answer

Reserve Fuel = TOM - Trip Fuel

Answer

MZFM = Traffic load + DOM

Question 9

What determines the longitudinal stability of an aeroplane?

Accepted Answer

The location of the centre of gravity with respect to the neutral point.

Answer

The effectiveness of the horizontal stabilizer, rudder and rudder trim tab.

Answer

The dihedral, angle of sweepback and the keel effect.

Answer

The relationship of thrust and lift to weight and drag.

Question 10

At the flight preparation stage, the following parameters in particular are available for determining the mass of the aircraft: 1- Dry operating mass 2- Operating mass. Which statement is correct:

Accepted Answer

The dry operating mass includes fixed equipment needed to carry out a specific flight.

Answer

The operating mass is the mass of the aircraft without take-off fuel.

Answer

The dry operating mass includes take-off fuel.

Answer

The operating mass includes the traffic load.
