1. 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:
2. 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) which is beyond limits. The captain decides then to redistribute part of the cargo load between cargo 1 (3,5 m from reference point) and cargo 4 (20,39 m from reference point) in order to obtain a new centre of gravity location at 31% MAC.
Given:
Distance from reference point to leading edge: 14 m, Length of MAC: 4,6 m
Captain asks for a transfer of:
.
3. 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. After the handling operation, the new centre of gravity location in % MAC will be:
4. 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:
5. A loaded aircraft weighs 4.200 lbs with a CG at 9 inches AFT of the datum. An extra 200 lbs is loaded into the aircraft 40 inches FWD of the datum. The new CG position is:
