Moment sum
Note :
The above chart shows MCR mean moment arms. It must be completed with the actual empty
weight and moment arm of the Aircraft. Also update if possible the actual moment arms of movable
weight by weighing your Aircraft (refer to MBENOPP Weighing procedure).
Calculation method
•
Note movable weights in fill above chart
•
Compute total mass
•
Multiply weights and corresponding moment arms and note the results in "Moment" column.
•
Compute the moment sum.
•
Divide the moment sum by the total weight. The result gives the location in meter of the actual
Aircraft centre of gravity.
•
Check the computed moment arm is within the weight and balance envelope shown on previous.
