What occurs during the aerodynamic conditions at spin entry?

During spin entry, the aerodynamic conditions involve a specific interaction between the wings of the aircraft as it begins to rotate around its vertical axis. In a spin, it is crucial to understand the behavior of each wing during this phase.

When the aircraft enters a spin, the dropped wing, or the wing that is going downwards in the spin, is in a fully stalled condition. This means it has exceeded its angle of attack to the point where it cannot produce any lift. Conversely, the rising wing – the wing that moves upwards in the spin – may still have a lesser angle of attack and is often in a state where it can, at least partially, produce lift despite nearing stall conditions.

Thus, the correct description of the situation is that the dropped wing continues to stall, resulting in a loss of lift, while the rising wing may begin to regain some lift due to a lesser angle of attack. This combination creates the characteristic rotation and descent of the spin. Understanding this interaction is critical for spin recovery techniques, emphasizing the importance of addressing each wing's aerodynamic state during the maneuver.

In summary, the dropped wing remains stalled (thus producing no lift), while the rising wing might regain lift to some extent, which leads to the continuing dynamics of
