The center of gravity (or CG) depends on the particular type of aircraft due to each type having different overall size characteristics. Aircraft have lateral CG's, Longitudinal CG's, and even Vertical CG's. Each has to be taken into consideration, but the Longitudinal CG (Forward and Aft) is the most important. The aircrafts center of lift is where this CG is located. There is a Forward CG limit, and an Aft CG limit. Depending on the flight characteristics of the type of aircraft, your CG window could be bigger, or smaller.

Center of gravity for an airplane?
The center of gravity is a point on the airplane that the airplane would balance while sitting on the ground. The center of gravity or also called "the CG" is important in trimming the aircraft in flight as the weight has to balance out the forces on the wing. It is also important in aerodynamic maneuvers as the G-forces act through CG.
What force is activated because of the mass of the airplane and works to pull an airplane to the ground?
Gravity
What happens to the airplane if the center of gravity is too far forward?
If the center of gravity is too far forward, the airplane may become difficult to control, with a tendency to pitch down uncontrollably. This can lead to instability and potential loss of control in flight. Pilots must ensure that the center of gravity remains within the specified limits for safe operation.
What is the significance of the empty weight center of gravity range of an aircraft?
If the cg is not with in range the airplane will crash.
How does adding paperclips to the nose of a paper plane affect its flight?
It shifts the center of gravity forward. If the paper airplane originally had the center of gravity too far back, causing it to nose up and stall a paperclip or two can correct this and produce stable flight. If the paper airplane originally had the center of gravity correctly positioned or was too far forward the paperclip will cause it to nose down and crash.
What force pull an airplane towards the earth and is related to the mass of the airplane?
The force that pulls an airplane towards the Earth is gravity. Gravity is directly related to the mass of the airplane, meaning that the greater the mass of the airplane, the stronger the force of gravity pulling it towards the Earth.
What determines the longitudinal stability of an airplane?
The longitudinal stability of an airplane is primarily determined by the location of the center of gravity (CG) in relation to the aerodynamic center of the wing. If the CG is in front of the aerodynamic center, the airplane tends to be stable. If the CG is too far behind the aerodynamic center, the airplane can become unstable. Pilots use the elevator control surface to adjust the pitch and maintain longitudinal stability.
Does the center of mass of an object ever differ from the center of gravity?
The center of mass and center of gravity serve two separate purposes. As an individual, your center of gravity and center of mass remains the same. The earth has a center of mass. The moon has a center of mass. The moon does not orbit the earth. They orbit their center of gravity. Their center if gravity is always changing. It is not a fixed point. When an airplane takes off, its center of gravity is one place. As it burns fuel, its center of gravity changes. It might be necessary to change its attitude, which today is done automatically by computers. The computers are checked at the end of the flight by human beings.
Where should the center of gravity be at all times in relation to the center of lift?
The placement of the center of gravity (CG) and the center of lift (CL) affects pitch stability. When engineers design an airplane, it is usually designed so the center of gravity is placed forward of the center of lift. With this "built in stability" if a plane goes into an abrupt dive, the aerodynamic forces will bring the nose back up to level flight.
How do you balance an RC airplane?
You must find the center of gravity by balancing it. Add weight to the front of the plane. This keeps a flight stable.
