1. If the loaded mass is 27.220 kg, how much load should be transferred 9,16 m forward from no. 2 hold to the no. 1 hold in order to move the centre of gravity of an aircraft from the out of limits value of 13 metres aft to the forward limits value of 11,6 metres aft?
2. The CG of an aircraft is 980 inches aft of datum at an all up mass of 170.500 lbs. If 800 lbs of baggage is moved from FS 1130 to FS 430 the new CG will be:
3. 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?
4. 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?
5. The CG of an aircraft is at 25% MAC and MAC is 1 m. The aircraft has 2 holds, hold 1 is 7 m aft of the datum and hold 2 is 22 m aft of the datum. If the aircraft mass is 38.000 kg, what load must be transferred from hold 1 to hold 2 to move the CG to 40% MAC?
