Where is the center of gravity (CG) range typically located in a helicopter?

The center of gravity (CG) range in a helicopter is important in determining its stability and handling characteristics during flight. Typically, the CG is located a short distance fore and aft of the main rotor mast to ensure proper balance and control. This positioning aids in achieving optimal aerodynamic performance and allows for better maneuverability.

When the CG is positioned within this range, it supports the helicopter's ability to perform effectively during various phases of flight, including takeoff, hovering, and landing. Proper positioning of the CG also minimizes pilot workload and enhances safety by preventing adverse flight characteristics that arise from an improperly balanced helicopter.

In contrast, positions located too far in front of or behind the main rotor mast can lead to instability, difficulty in control, and increased likelihood of crashes. Thus, maintaining the CG within this short distance fore and aft of the main rotor mast is crucial for safe and efficient helicopter operation.
