Center of Gravity is the theoretical point where the entire weight of the helicopter is considered to be concentrated.

• A. Center of Gravity
• B. Center of Pressure
• C. Chord
• D. Chordwise Axis

Answer: (A)

The main idea here is the balance point of the aircraft. The Center of Gravity is the theoretical point at which the entire weight of the helicopter can be considered to be concentrated, and it serves as the pivotal reference for calculating moments about the aircraft. This location determines how the helicopter will respond to control inputs and how stable it will be in flight. If the CG is too far forward or aft, the aircraft can become difficult to control, require stronger control inputs, or even approach limits where controllability is compromised. That’s why keeping the CG within specified limits is critical for safe, stable flight. Center of Pressure is a different concept; it’s the point where the lift force is considered to act, and it can move with changes in airspeed and angle of attack, not a fixed weight location. The terms chord and chordwise axis relate to the geometric dimensions and axes of the rotor blades or airfoil, not to where the aircraft’s weight is concentrated.
