If the tail of a canopy is held lower than the nose after a dynamic stall, what is the result?

When the tail of a canopy is held lower than the nose after a dynamic stall, it leads to a full stall of the parachute. In this scenario, the angle of attack of the canopy becomes excessive, causing airflow over the surface of the wings to separate entirely. This results in a significant loss of lift and can lead to a rapid descent or a potentially uncontrollable situation.

Understanding the dynamics of a parachute during a stall is critical for safety and control in freefall. In a full stall, the canopy cannot produce adequate lift, which may also lead to erratic behavior of the parachute as it descends. This can result in a range of dangerous situations, including a spin or other uncontrollable flight patterns, emphasizing the importance of maintaining proper flying techniques and understanding the canopy's behavior during different maneuvers.

In contrast, a controlled descent or partial stall would not result in the same extreme loss of control and lift efficiency as a full stall. An increase in lift under these circumstances is also not possible, as the stall condition directly leads to a reduction in lift capability, complicating recovery efforts and maintaining a stable flight path. Thus, recognizing a full stall is essential for emergency management and safe parachuting practices.
