Manufacturer-Furnished Information When an aircraft is initially certificated, its empty weight and EWCG are determined and recorded in the weight and balance record, such as the one in Figure 1. Notice in this figure that the moment is expressed as “Moment (lb-in/1,000).” This is a moment index, which means that the moment, a very large […]
Weight and balance in aircraft is based on the law of the lever. This section discusses the application of the law of the lever and its applications relative to locating the balance point of a beam or lever on which various weights are located or shifted. The chapter also discusses the documentation pertaining to weight
Shifting the Balance Point or CG One common weight and balance problem involves moving or shifting weight from one point to another in order to move the balance point or CG to a desired location. This can be demonstrated by using a lever with three weights to work out the problem. Solution by Chart As
Weight and Balance Theory Two elements are vital in the weight and balance considerations of an aircraft. The total weight of the aircraft must be no greater than the maximum weight allowed by the FAA for the make and model of the aircraft. The center of gravity (CG), or the point at which all of
