AIRCRAFT WEIGHING PROCEDURE
The aircraft weight is determined by weighing all three wheel loads simultaneously by three
scales with the aircraft levelled.
(Upper fuselage reference line horizontal)
Datum line for weight arms x is the fire wall.
X1 = distance: fire wall - main wheel
X2 = distance: fire wall - tail wheel
XN = distance: fire wall - item N
XG = distance: fire wall - Center of Gravity
W1 = Sum of weights indicated by the two scales below the main wheels
W2 = Weight indicated by the scale below the tail wheel
W = Total weight = W1 + W2
XG = (W1 x X1) + (W2 x X2) = CG position
W
W = W1 + W2 ,
(W1 x X1) + (W2 x X2)
