How can improper weight and balance affect an aircraft?

Improper weight and balance can significantly impact an aircraft's stability, control, and overall performance. When an aircraft is not loaded within its specified weight limits or if the weight distribution is incorrect, it can lead to several issues during flight. For instance, if the center of gravity is too far forward or too far aft, it can result in difficulties in controlling the aircraft, which may manifest as excessive nose-up or nose-down attitudes. This can affect the pilot's ability to manage flight controls effectively, leading to potential safety hazards like stalls or difficulties in executing turns.

Additionally, an improperly balanced aircraft may experience increased drag, which can affect fuel efficiency and performance during climbing, cruising, and descending phases of flight. In essence, correct weight and balance are crucial for maintaining the intended flight characteristics of an aircraft, ensuring that it operates safely and efficiently.
