(For this question use annex ECQB-031-048-v2015-07).
Calculate the centre of gravity if the mass of the baggage is increased to 50 kg.
  • A
    85.79 kg.mm
  • B
    86.41 kg
  • C
    85.79 mm
  • D
    87.59 mm
Center of gravity = Total moment / total mass

In the question its mentioned that we will increase the mass of baggage from 20 kg to 50 kg:
Total mass will increase by 30 kg = 3630 + 30 = 3660 kg

Total moment will increase by value of (30 x 200) = 6000 kg.mm
New moment = 308000 + 6000 = 314000 kg.mm

New CG = 314000 / 3660 = 85.79 mm
