Refer to figure or CAP758 Figure 3.25.
Calculate the moment of a 800 kg single pallet loaded on a helicopter for a CAT offshore operation.

  • A

    3760 kgm

  • B

    4.700 m

  • C

    3112 kgm

  • D

    4552 kgm

Refer to figure.
Moment is the turning force created around a datum by the mass over a distance or lever arm and given by the formula:

  • Moment = Mass x Arm

For this question, advise the CAUTION in the middle of the figure:

  • WHEN LOADING A SINGLE PALLET, IT MUST BE INSTALLED IN THE CG NEUTRAL POSITION (DATUM + 4.700 m)

Therefore, the moment of a 800 kg single pallet will be:

  • Moment = Mass x Arm
  • Moment = 800 kg x 4.7 m
  • Moment = 3760 kgm
