What can happen to the aircraft's attitude during a stall with an aft center of gravity?

When an aircraft experiences a stall with an aft center of gravity, the dynamics of the aircraft's attitude can lead to the tail dropping instead of the nose. An aft center of gravity means that the center of mass is positioned towards the back of the aircraft, which significantly affects stability and control.

In such a configuration, during a stall, the aircraft can enter a state where it has difficulty maintaining a positive angle of attack. As the airflow separates from the wings at a lower angle of attack, the pitch control becomes less effective due to the shift in balance. This position can cause the nose to not pitch down as expected, leading to the tail dropping instead. The resultant attitude can be characterized by an increased risk of a tailplane stall due to reduced airflow over the horizontal stabilizer, exacerbated by the aft center of gravity's effects.

Understanding how the aircraft's center of gravity influences stall behavior is critical for safe flying practices, especially when performing maneuvers close to the stall margin. This is why a tail drop is a notable characteristic in such scenarios among pilots.
