Imagine a paraglider cuts his main chute and reaches terminal velocity. Can he still land safely when he deploys hes rescue chute?
The european standards require that paragliding rescue chutes can handle opening shocks as high as 60 m/s at full load. Google tells me that termial velocity is around 53 m/s for a human skydiver. Is that requirement enough to safely say it can handle terminal velocity? Note that a paraglider can have equipment up to 15kg. Is it possible one could hurt himself when opening paraglider rescue chute because they can open to fast?
EDIT: I've found this post where somebody talks about how he deployed a hangglider reserve while he was falling at terminal velocity. He talks about how he survived and how he has seen another similar case where it went the other way.
