6.3 LOADING SYSTEM
The Loading Trim Sheets on the following pages will assist the pilot in ensuring that the J160-C is
operated within the prescribed weight and centre of gravity limitations. The chart is a graphic
representation of the weight and balance calculations for the aircraft. It performs two functions –
the vertical scales on the right hand side of the chart provide a graphical method to calculate the
operating weights of the aircraft, while the horizontal scales and the crew index chart at the top of
the chart provide a graphical method to calculate the cg positions.
The aircraft is loaded correctly, only if
BOTH the zero fuel and the takeoff cases fall inside the
boundary line on the graph.
The chart is based on an aircraft “EMPTY WEIGHT TRIM INDEX” which is calculated using the
following formula:
{(Aircraft Empty Weight) * (Empty Weight Arm)}
Empty Weight Trim Index =
1000
Example Trim Index Calculation:
Aircraft Empty Weight
= 275-kg
Aircraft Empty Weight Arm = 180-mm aft of datum
Empty Weight Trim Index = (275 x 180) / 1000
= 49.5
6.3.1 Baggage Zones
The cabin has one baggage zone:

Baggage is restrained using the straps fitted in the baggage areas.
