What happens to the parachute canopy during the automatic sequence at high altitude?

During the automatic sequence at high altitude, the parachute canopy will remain closed above 18,000 feet MSL. This is designed to enhance safety and effectiveness during parachute deployment. At high altitudes, such as above this threshold, several factors come into play, including decreased air pressure and temperature, which can impact the deployment process.

By keeping the parachute closed above 18,000 feet, the system helps ensure that the parachute does not deploy prematurely in conditions where the jump might not be optimal. Specifically, there is a risk of issues such as lack of oxygen and increased risks of hypoxia at these higher altitudes, which can affect a jumper’s performance and decision-making.

Once the altitude is appropriate for deployment, the parachute can then open at lower, safer altitudes where conditions are more favorable for a successful landing. This protocol is crucial for ensuring the safety and efficiency of parachute operations.
