How Moment (and Weight or Arm) are calculated

For flight, one needs to know (i.e. calculate) the C of G (Center of Gavity) of the aircraft. To achieve this, a load sheet must be completed which quantifies exactly what is being carried, their weights and where on the aircraft they are being carried. Use this tool to calculate these elements for each item carried.

C of G (moment) is equal to mass multiplied by arm, hence re-arranging gives the equation above.
