Notes

Rating

Safety class 5

This class of paraglider reacts very demandingly to one or more of the following manoeuvres: frontal collapse, asymmetric collapse or spiral dive and may present pilots with a particular challenge.
Very demandingly means that the above manoeuvres result in highly dynamic reactions from the glider, and/or large height losses. Critical subsequent glider reactions are also to be expected.

Expert piloting skills achieved through constant practice, fast personal reaction times and precise pilot inputs are required to be able to immediately react to the above manoeuvres to maintain flight control and prevent large height loss or subsequent critical glider reactions. In particular, pilots should be able to recognise the onset of the above manoeuvres and be able to prevent or minimise their effects through immediate and precise pilot inputs.
