Test 10 domande Mass and Balance, tempo libero

1 - The flight preparation of a turbojet aeroplane provides the following data: Take-off runway limitation: 185 000 kgLanding runway limitation: 180 000 kgPlanned fuel consumption: 11 500 kgFuel already loaded on board the aircraft: 20 000 kg Knowing that:Maximum take-off mass (MTOM): 212 000 kg Maximum landing mass (MLM): 174 000 kg Maximum zero fuel mass (MZFM): 164 000 kg Dry operating mass (DOM): 110 000 kgThe maximum cargo load that the captain may decide to load on board is: 54 000 kg 61 500 kg 55 500 kg 55 000 kg

2 - A load placed forward of the datum Has a negative arm and therefore generates a negative mass and moment Has a positive arm and therefore generates a positive mass and moment Has a negative arm and therefore generates a negative moment Has a positive arm and therefore generates a positive moment

3 - The Maximum Zero Fuel Mass is a structural limiting mass. It is made up of the aeroplane Dry Operational mass plus Traffic load, non-revenue load and crew standard mass. Unuseable fuel and crew standard mass. Traffic load Traffic load and potable water.

4 - At a given mass the CG position is at 15% MAC. If the leading edge of MAC is at a position625.6 inches aft of the datum and the MAC is given as 134.5 inches determine the position of the CG in relation to the datum. 605.43 inches aft of datum 20.18 inches aft of datum If the leading edge of MAC is at a position625.6 inches aft of the datum and the MAC is given as 134.5 inches determine the position of the CG in relation to the datum. 605.43 inches aft of datum 20.18 inches aft of datum 228.34 inches aft of datum 645.78 inches aft of datum

5 - . Overloading has the following effects on performance: Reduced take off and landing distance, increased VNE and increased fuel consumption Increased take off and landing distance, increased rate of climb and increased fuel consumption Reduced take off and landing distance, increased VNE and reduced rate of climb Increased take off and landing distance, reduced rate of climb and increased fuel consumption

6 - . The mass of an item multiplied by it's distance from the datum is it's Moment Force Moment arm Centre of gravity

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: 1 550 kg 2 200 kg 1 600 kg 2 150 kg

8 - . The operating mass of an aeroplane is: The empty mass plus crew, crew baggage and catering. The empty mass plus the take-off fuel mass. The empty mass plus the trip fuel mass. The dry operating mass plus the take-off fuel mass.

9 - An aeroplane is said to be 'neutrally stable'. This is likely to: Be caused by a centre of gravity which is towards the forward limit Be totally unrelated to the position of the centre of gravity Be caused by a centre of gravity which is towards the rearward limit Cause the centre of gravity to move forwards

10 - Refer to CAP 696 Fig. 4.11:At the maximum landing mass the range of safe CG positions, as determined from the appropriate graph in the loading manual, is:

Forward limit 7.4% MAC aft limit 27.0% MAC Forward limit 8.0% MAC aft limit 26.8% MAC Forward limit 8.6% MAC aft limit 27.0% MAC Forward limit 8.0% MAC aft limit 27.2% MAC
