What may happen if an aircraft's center of gravity is improperly positioned?

When the center of gravity (CG) of an aircraft is not properly positioned, it significantly affects the aircraft's stability and control. An improperly positioned CG can lead to several issues, such as increased difficulty in controlling the aircraft during maneuvers, and reduced effectiveness of the flight controls.

For instance, if the CG is too far forward, the aircraft may have a tendency to pitch down and require considerable force on the control yoke or stick to maintain level flight. Conversely, if the CG is too far aft, the aircraft may become prone to uncontrollable nose-up attitudes, jeopardizing the ability to recover from stalls.

Ultimately, these issues can lead to a dangerous flying environment, where normal handling characteristics are compromised, and pilots may find it challenging to execute standard flight maneuvers safely. Thus, maintaining the correct CG is crucial for ensuring the aircraft's stability and overall flight safety.
