Moreoil, migh I kindly suggest you go and revise a bit of air law. Specifically on who has right of way in the air. The pecking order is quite clear.
Reaching for my EASA IR notes I can only see references to powered aircraft having to give way to airships, balloons and gliders...no reference to parachutes.
Reference perhaps?
I'd never thought to look it up because I always try to steer clear of parachute sites anyway but now that you mention it I'd be interested to know where in the rules of the air it is actually written. Quick check of the ANO didn't reveal anything either.
