1 - The distance from the datum to the Centre of Gravity of a mass is known as The moment arm or balance arm. The index. The moment. The force.

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: 14383 kg 11364 kg 13647 kg 18206 kg

3 - During take-off you notice that, for a given elevator input, the aeroplane rotates much more rapidly than expected. This is an indication that : The centre of gravity may be towards the aft limit. The centre of pressure is aft of the centre of gravity. The centre of gravity is too far forward. The aeroplane is overloaded.

4 - What are the standard masses used for crew? 88 kgs for flight crew, 76 kgs cabin crew, not including baggage 85 kgs for flight crew, 75 kgs cabin crew, not including hand baggage 88 kgs for flight crew, 76 kgs cabin crew, including baggage. 85 kgs for flight crew, 75 kgs cabin crew, including hand baggage

5 - 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 mThe aircraft mass is 2 200 kg and its centre of gravity is at 25% MACTo move the centre of gravity to 40%, which mass has to be transferred from the forward to the aft cargo hold? 110 kg 104 kg 165 kg 183 kg

6 - Where is the centre of gravity of the aeroplane in the diagram?

26.57 cm forward of datum. 32.29 cm aft of datum. 26.57 cm aft of datum. 32.29 cm forward of datum.

7 - The standard mass for a child is 35 kg for holiday charters and 38 kg for all other flights. 35 kg for all flights. 30 kg for holiday charters and 35 kg for all other flights. 38 kg for all flights.

8 - A pallet having a freight platform which measures 200 cm x 250 cm has a total mass of 300 kg. The pallet is carried on two ground supports each measuring 20 cm x 200 cm.Using the loading manual for the transport aeroplane, calculate how much mass may be added to, or must be off loaded from, the pallet in order for the load intensity to match the maximum permitted distribution load intensity for lower deck forward cargo compartment.

28.5 kg must be off loaded. 28.5 kg may be added. 285.5 kg may be added. 158.3 kg must be off loaded.

9 - Comparing a forward CG position with an aft one, the forward cg position will cause a Decrease in the landing speed. Decrease in range. Tendency to yaw to the right on take-off. Decrease of the stalling speed.

10 - The mass of an aircraft is 1950 kg. If 450 kg is added to a cargo hold 1.75 metres from the loaded centre of gravity (cg). The loaded cg will move: 40 cm. 33 cm. 34 cm. 30 cm.
