What is the appropriate response for closed end cells during a jump?

In the context of parachuting, when you encounter a closed end cell situation during a jump, the appropriate response is to pull the toggles to the flare position and hold. Closed end cells occur when air is not able to flow into the cells of the canopy properly, typically resulting in a decreased level of control and an increase in the risk of a hard landing. By pulling the toggles to the flare position, you are effectively utilizing the canopy’s design to open the end cells by increasing the angle of attack. This action helps to maintain some lift and control, providing the opportunity to stabilize the canopy before landing.

This response is crucial as it can prevent major issues that can arise from inadequate airflow through the canopy. Monitoring altitude without taking action can lead to a dangerous situation as the parachute may not function properly, and deploying the reserve parachute should only be considered if the main canopy is absolutely uncontrollable or unreachable conditions arise. Releasing all toggles would exacerbate the situation and further reduce control over the canopy, which is why holding them in the flare position is the best course of action.
