## Weight and Balance of Aircraft

One of the essential conditions for the safe and effective operation of aircraft is that the weight and center of gravity (C of G). The aircraft manufacturer determines the basic weight and C of G of each aircraft. However, these values may change in service as a result of modifications, repainting, replacement of major components, […]

## Determining Aircraft Loaded Weight and Center of Gravity

There are various methods for determining the loaded weight and CG of an aircraft. There is the computational method as well as methods that utilize graphs and tables provided by the aircraft manufacturer. Computational Method The following is an example of the computational method involving the application of basic math functions.     Aircraft Allowances:

## Balance, Stability, and Center of Gravity – Aircraft Weight and Balance

Balance refers to the location of the CG of an aircraft, and is important to stability and safety in flight. The CG is a point at which the aircraft would balance if it were suspended at that point. The primary concern in balancing an aircraft is the fore and aft location of the CG along

## Weight Control

As discussed in earlier, Aerodynamics of Flight, weight is the force with which gravity attracts a body toward the center of the Earth. It is a product of the mass of a body and the acceleration acting on the body. Weight is a major factor in aircraft construction and operation and demands respect from all
