1. An aeroplane, whose specific data is shown in the annex, has a planned Takeoff Mass of 200.000 kg, with its centre of gravity (CG) is located at 15,38 m rearward of the reference point, representing a CG location at 30% MAC (Mean Aerodynamic Cord). For performance purposes, the captain decides to reset the value of the centre of gravity location to 35% MAC. The front and rear cargo compartments are located at a distance of 15 m and 25 m from the reference point respectively, the cargo load mass which needs to be transferred from the front to the rear cargo compartment is:
2. A jet aeroplane, with the geometrical characteristics shown in the appendix, has a takeoff weight (W) of 460.000 N and a centre of gravity (point G on annex) located at 15,40 m from the zero reference point. At the last moment the station manager has 12.000 N of freight added in the forward compartment at 10 m from the zero reference point. The final location of the centre of gravity, calculated in percentage of Mean Aerodynamic Chord AB (from point A), is equal to:
3. A turbojet aeroplane has a planned Takeoff Mass of 190.000 kg. Following cargo loading, the crew is informed that the centre of gravity at takeoff is located at 38% MAC (Mean Aerodynamic Cord). The captain then decides then to redistribute part of the cargo load between cargo 1 and cargo 4 in order to obtain a new centre of gravity location at 31% MAC. He asks for a transfer of:
4. The Taxi Mass of the aircraft is 62.500 kg and the centre of gravity is calculated at 20% MAC. A load weighing 1.000 kg is moved from the forward section of the aft cargo compartment to the aft section of the forward cargo compartment. The new centre of gravity position is:
5. A mass of 500 kg is loaded at a station which is located 10 metres behind the present centre of gravity and 16 metres behind the datum. The moment for that mass used in the loading manifest is (Assume: g=10 m/s2):
