After keying in the airplane's empty weight and arm, the next
step is to calculate the weight and balance for the aircraft at
takeoff. For this example, we'll assume the following load:
Item
Weight
Arm
Fuel
72.5 gal (6 lbs./gal.)
75
Front passengers
340
75
Rear passengers
340
115
Baggage

Press ENTER
Key in A R M of 7 5
Press ENTER
New totals will appear for MOM, CG and GW. The passengers
can be added onto the total in the same manner the fuel was
added above. RF will remain the same throughout the problem;
therefore, you will only be prompted once for the RF. The final
calculations can be used to confirm that the weight and CG are
within the airplane's operating limitations.
WEIGHT AND ARM (cont.)
(WT/ARM)
When finished, the cumulative totals will be displayed. The
screen will display:
Weight can also be moved or subtracted. Suppose one of the
rear seat passengers can't make the trip:
Key in W T of 1 7 0 and press
