Abstract
The problems encountered in weighing aircraft are of vital concern from both an economy and safety standpoint. In the field of aircraft weight and balance, engineers are fully aware of not only the necessity of keeping all the component weights in an aircraft at minimum, but also the vital necessity to know the weight and location of the center of gravity of the aircraft prior to takeoff. The control of the center of gravity must be maintained within given limits for each type of aircraft. Techniques used to determine the weight and center of gravity consists of weighing the aircraft in an unloaded condition, dry and with removable components off the aircraft. Once this is determined, the aircraft is loaded and loaded weight determined. The center of gravity is computed as each component is added to the basic weight of the aircraft.
This paper addresses the different techniques that have been used in weighing the aircraft and some difficulties encountered. Some techniques that are addressed are jacking systems, mechanical scales, computer computations that are semi-automatic or automatic devices.
