Storing a parachute in a car during the summer exposes it to high temperatures, which can adversely affect various components of the parachute system. One significant issue is the shorter life of AAD (Automatic Activation Device) batteries. AADs are sensitive to temperature extremes; prolonged heat can accelerate battery deterioration, potentially leading to unexpected failure during a jump.
Additionally, stow bands, which keep the parachute system neatly packed and ready for deployment, can degrade more rapidly in high temperatures. The elasticity of the bands may weaken, increasing the risk of failure when the parachute is deployed. This degradation might not only affect the performance of the parachute but could also compromise safety.
The other concerns, such as reduced altitude performance or tears in the canopy fabric, stem from different issues, like improper packing or material fatigue over time. The risk of blush discoloration relates more to aesthetics rather than functional safety, while the significant impacts of temperature on battery life and stow band integrity are far more critical for ensuring safe jumps.
