I had always assumed that an aircraft's "dry weight" was equal to its "empty weight" minus the fuel load. In other words the "dry weight" plus the weight of the fuel equals the "empty weight"(the weight of the aircraft before loading passengers or cargo).
In my aircraft's .air file there is a 2,180 lb. disparity between these comparative weights(a "dry weight" of 4,524 lbs. and 900 lbs. of fuel, versus an "empty weight" of 7,604 lbs.). Have I been misinformed about the meanings of these flight dynamics terms or is there misinformation in the .air file? Thanx for your help.
