1. The Total Mass of an aeroplane is 145.000 kg and the centre of gravity limits are between 4,7 m and 6,9 m aft of the datum. The loaded centre of gravity position is 4,4 m aft. How much mass must be transferred from the front to the rear hold in order to bring the out of limit centre of gravity position to the foremost limit?
2. 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):
3. 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?
4. The planned Takeoff Mass of a turbojet aeroplane is 180.000 kg, with its centre of gravity located at 26% MAC (Mean Aerodynamic Cord). Shortly prior to engine start, the local staff informs the flight crew that 4.000 kg must be unloaded from cargo 4 (23,69 m aft of reference point).
Given:
Distance from reference point to leading edge: 14 m, Length of MAC: 4,6 m
After the handling operation, the new centre of gravity location in % MAC will be?
.
5. An aircraft has a taxi mass of 30.000 kg and its centre of gravity is 21,69 m aft of datum. What would be the new centre of gravity if 1.000 kg were moved 30 m forward from hold 2 to hold 1?
