	* Arm for Pilot or passenger center of gravity on adjustable seats positioned for average occupant (used in above W&B Calculator). Number in parentheses indicate forward and aft limits of occupant center of gravity range ** Arm Measured to center of areas shown. These values are used in the above W&B calculator NOTE: The rear cabin wall (appoximate station 108) or aft baggage wall (approximate station 142) can be used as a convenient interior reference points for determining the location of baggage area fuselage stations.
