A loaded aircraft has its Centre of Gravity (CG) 48 inches forward of the datum, and its mass is 2 966 lb. If a last minute load of 128 lb is added 28 inches aft of the datum. What is the new position of the CG?

  • A
    44.72 inches forward of the datum.
  • B
    46.84 inches aft of the datum.
  • C
    44.86 inches forward of the datum.
  • D
    46.01 inches aft of the datum.

New Total Moment = Old Total Moment + Additional Load (m)

(2966 + 128) x d = - (2966 x 48) + 128 x 28
3094 x d = -142368 + 3584
3094 x d = -138784
d = - 138784 / 3094 = -44.85 inches (Forward of the datum)
