GDU 37X Installation Manual Page 4-5190-01054-01 Revision C4.4.3 W/B (Weight/Balance) Configuration PageThe W/B Configuration Page allows setting the weight and balance parameters for the airplane, theseparameters are then used on the Main Menu W/B Page in normal mode. Weight/Balance may be usedduring pre-flight preparations to verify the weight and balance conditions of the aircraft. By entering theweight and arm values into the Aircraft window, the GDU 37X can calculate the total weight, moment, andcenter of gravity (CG).Before entering the various figures, the empty weight of the airplane and the arm (or “station”) for eachweight should be determined. These figures should be determined using the pilot’s operating handbook forthe airplane, which also notes the weight limitations and fore/aft CG limits. Compare those figures to thevalues calculated by the GDU 37X.Each station listed in the Station window has an editable name and arm location. This allows the setting ofthe units of measure used for that station (weight, or units of avgas or jet fuel). Optionally a maximumvalue can be set for a particular station (e.g. a fuel tank might have a max capacity of 50 gallons) or themax 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.1.
