15 / 20

The calculated CG before take-off is 8 cm beyond the CG limit. The aircraft has a total mass of 7132 kg. In order to have a CG within limits, a mass of 320 kg can be shifted within the hold. How much should you move this mass?

  • A

    0.358 m

  • B

    186.3 cm

  • C

    170.3 cm

  • D

    1.783 m

Use the formula:

Mass Change / Total Mass = Change of CG / Distance

  • Mass Change: 320 kg
  • Total Mass: 7132 kg
  • Change of CG: 8 cm = 0.08 m
  • Distance: ?

320 kg / 7132 kg = 0.08 m / Distance
Distance = (7132 kg / 320 kg) x 0.08 m
Distance = 1.783 m

The mass of 320 kg has to be moved by 1.783 m.
