===WEIGHT AND CG CALCULATION===
 
Total weight is calculated by adding total weight of empty aircraft, fuel, passengers and baggage. Fuel weight can be calculated assuming 7 pounds per gallon of (Jet-A) fuel. The CG is obtained by dividing total moment by total weight. Moment at each station is obtained by multiplying the arm of that station by the weight at that station. Total moment is obtained by adding moment for each station and the moment for the empty aircraft.

SECTION 5. WEIGHT AND BALANCE

The helicopter must be flown within the weight and CG (Center of Gravity) limits as specified in this section. Failure to adhere to these limitations will result in unpredictable performance. CG is measured in inches aft of the datum plane. The datum plane is located at the forward most point of the nose.

1 WEIGHT AND CG LIMITS

The weight and CG limits for this aircraft are:

Max Gross Weight: 47,000 lb
Max Forward CG: 350 inches
Max Aft CG: 385 inches

2 EMPTY WEIGHT AND CG

The empty weight and CG of this aircraft are:

Empty Weight: 19,234 lb
Empty Aircraft CG: 356.8 in
Empty Moment: 6.863 M-lb-in

3 CG ARM DATA

The following arm data can be used to calculate moment at each of these stations.

Pilot/Co-Pilot 64.7 in (1.64 m)
Aft Pilot/Jumpseat 119.0 in (3.03 m)
Fuel 295 in (7.50 m)

4 WEIGHT AND CG CALCULATION

Total weight is calculated by adding total weight of empty aircraft, fuel, passengers and baggage. Fuel weight can be calculated assuming 7 pounds per gallon of (Jet-A) fuel. The CG is obtained by dividing total moment by total weight. Moment at each station is obtained by multiplying the arm of that station by the weight at that station. Total moment is obtained by adding moment for each station and the moment for the empty aircraft.
