Question 1

When the centre of gravity is at the forward limit, an aeroplane will be:

Accepted Answer

Extremely stable and will require excessive elevator control to change pitch.

Answer

Extremely stable and require small elevator control to change pitch.

Answer

Extremely unstable and require small elevator control to change pitch.

Answer

Extremely unstable and require excessive elevator control to change pitch.

Question 2

The maximum quantity of fuel that can be loaded into an aircraft's tanks is given as 3800 US Gallons. If the fuel density (specific gravity) is given as 0.79 the mass of fuel which may be loaded is:

Accepted Answer

11364 kg

Answer

14383 kg

Answer

13647 kg

Answer

18206 kg

Question 3

A load placed aft of the datum:

Accepted Answer

Has a positive arm and therefore generates a positive moment

Answer

Has a negative arm and therefore generates a negative moment and mass

Answer

Has a negative arm and therefore generates a negative moment but a positive mass

Answer

Has a positive arm and therefore generates a positive moment but negative mass

Question 4

A jet transport has the following structural limits:-Maximum Ramp Mass: 63 060 kg-Maximum Take-off Mass: 62 800 kg-Maximum Landing Mass: 54 900 kg-Maximum Zero Fuel Mass: 51 300 kg. The aeroplane's fuel is loaded in accordance with the following requirements:-Taxi fuel: 400 kg. -Trip fuel: 8400 kg. -Contingency & final reserve fuel: 1800 kg. -Alternate fuel: 1100 kg. If the Dry Operating Mass is 34930 kg, determine the maximum traffic load that can be carried on the flight if departure and landing airfields are not performance limited.

Accepted Answer

16 370 kg

Answer

16 430 kg

Answer

17 070 kg

Answer

16 570 kg

Question 5

Dry Operating Mass is the mass of the aircraft less

Accepted Answer

Usable fuel and traffic load.

Answer

Usable fuel, potable water and lavatory chemicals.

Answer

Traffic load, potable water and lavatory chemicals.

Answer

Usable fuel.

Question 6

The weight of an aircraft, which is in level non accelerated flight, is said to act

Accepted Answer

Vertically through the centre of gravity.

Answer

Vertically through the centre of pressure.

Answer

Always along the vertical axis of the aircraft.

Answer

Vertically through the datum point.

Question 7

An aircraft basic empty mass is 3000 kg. The maximum take-off, landing, and zero-fuel mass are identical, at 5200 kg. Ramp fuel is 650 kg, the taxi fuel is 50 kg. The maximum traffic load is:

Accepted Answer

1 600 kg

Answer

1 550 kg

Answer

2 200 kg

Answer

2 150 kg

Question 8

Length of the mean aerodynamic chord = 1 m Moment arm of the forward cargo: -0,50 m Moment arm of the aft cargo: + 2,50 m. The aircraft mass is 2 200 kg and its centre of gravity is at 25% MAC. To move the centre of gravity to 40%, which mass has to be transferred from the forward to the aft cargo hold?

Accepted Answer

110 kg

Answer

104 kg

Answer

165 kg

Answer

183 kg

Question 9

Regarding centre of gravity position and longitudinal stability, which of the following statements is correct?

Accepted Answer

A tail heavy aeroplane is less stable and stalls at a lower speed than a nose heavy aeroplane

Answer

If the actual centre of gravity is located behind the aft limit of centre of gravity it is possible that the aeroplane will be unstable, making it necessary to increase elevator forces

Answer

The lowest stalling speed is obtained if the actual centre of gravity is located in the middle between the aft and forward limit of centre of gravity

Answer

If the actual centre of gravity is close to the forward limit of the centre of gravity the aeroplane may be unstable, making it necessary to increase elevator forces

Question 10

Traffic load is the difference between:

Accepted Answer

The take-off mass and the operating mass.

Answer

The operating mass and the basic empty mass.

Answer

The take-off mass and the basic empty mass.

Answer

The take-off mass and the basic empty mass plus trip fuel.
