Aeromodelling

The total weight distribution of an aircraft often assumes it concentrate and act through a single resultant point called the Center of Gravity. The aircraft would be perfectly balanced when it suspended through this point — ‘Center of Gravity’.

Aircraft maneuvering in flight, it rotates about the center of gravity. Therefore, the CG is an important point on an aircraft which significantly affects the stability of the aircraft.

Aircraft designer are very careful of placing those components that vary the aircraft overall weight and moving parts, such as fuel tanks, bombs and landing gear. Reduction of fuel in the tanks, dropping a bomb or lower down and retract of landing gear cause the position of CG shifted. The CG location is crucial for aircraft stability. It is important to place the components within the limit to maintain a stable and controllable in flight.
