Safety class 4

This class of paraglider reacts demandingly to one or more of the following manoeuvres: frontal collapse, asymmetric collapse or spiral dive.
Demandingly means that the above manoeuvres result in marked dynamic reactions from the glider and/or large height losses.

Advanced piloting skills which need to be regularly practised, together with good personal reaction times are required to safely fly this class of gliders. Basic recovery techniques for ending a manoeuvre are not sufficient to maintain control, reduce height loss to a minimum and prevent subsequent critical reactions. 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.

Additional experience such as regular ground handling and SIV training is required to safely fly gliders of this class. Special training or pilot skills which exceed standard training may be required for the safe performance of emergency descent techniques. Gliders of this Safety Class are not suitable for beginners, irregular flyers or low-airtime pilots.
