![]() ![]() can be expressed in several different ways: Center of Gravity can also be considered the point at which all the weight of the aircraft is concentrated.Aircraft weight must be distributed in accordance with the design described in the aircraft's flight manual.Therefore, designers fix the aft limit of the CG forward of the CP for the corresponding flight speed to retain flight equilibrium.If the CP is forward of the C.G., a nose-up pitching moment is created.When the CG is forward of the CP, there is a natural tendency for the aircraft to want to pitch nose-down.and the aerodynamic forces of lift occur at the Center of Pressure (CP) It is important to understand that an aircraft's weight concentrates at the C.G.This can result in a ground loop where the pilot is unable to stop the center of gravity from taking over directional control for the pilot/control surfaces.As discussed, the aircraft rotates about the center of gravity, meaning if directional control is lost due to erratic inputs or simply poor technique as airspeed decreases control surface effectiveness, the tail will want to come off to the side.The center of gravity for tailwheel aircraft are typically located behind the pilot.Performance impacts are due to lift/drag changes.Higher true airspeed due to lower angle of attack.Should the aircraft stall or spin, it will be much more difficult, if not impossible, to recover.The tail will feel heavy to compensate, which requires additional nose down-force.moves rearward (towards the tail), the arm between the center of gravity and the tail (downforce) decreases, thus the aircraft becomes more and more dynamically unstable High stall speeds (more airflow deflection of the elevator required to maintain altitude at slower airspeeds resulting in high Angles of Attack (AoA).Longer takeoff distance (more airflow required to provide more force to lift heavy nose).must always be within limits however, depending where in the allowable range the C.G. is of major importance in an aircraft, for its position (within a designed range) has a great bearing upon longitudinal stability It is computed during initial design and construction and is further affected by the installation of onboard equipment, aircraft loading, and other factors.The Center of Gravity is the specific point where the aircraft's mass or weight is said to center that is, a point around which, if the aircraft could be suspended or balanced, the aircraft would remain in place at any attitude.Pilot Handbook of Aeronautical Knowledge. ![]()
