34.4.14 Weight &/Balance Configuration Page
The Weight & Balance Configuration Page allows setting the weight and balance parameters for the
airplane. These parameters are then used on the Main Menu W/B Page in normal mode. Weight/Balance
may be used during pre-flight preparations to verify the weight and balance conditions of the aircraft. By
entering the weight and arm values into the Aircraft Empty window, the GDU 4XX can calculate the total
weight, moment, and center of gravity (CG).
Before entering the various figures, the empty weight of the airplane and the arm (or “station”) for each
weight should be determined. These figures should be determined using the pilot’s operating handbook for
the airplane, which also notes the weight limitations and fore/aft CG limits. Compare those figures to the
values calculated by the GDU 4XX.
Each station listed in the Station window has an editable name and arm location. This allows the setting of
the units of measure used for that station (weight, or units of avgas or jet fuel). An optional maximum
value can be set for a particular station (e.g. a fuel tank might have a max capacity of 50 gallons) or the
max can be set to zero so that no maximum will be imposed.
The Loading Limits window contains fields for the entry of minimum and maximum aircraft weight, and
the minimum and maximum CG location.
