Launch preparations: easy
launch characteristics: balanced, climbs constantly, no guidance necessary, good feedback during inflation, no braking required, slows before zenith, control check simple, low takeoff speed
asymmetric collapse: canopy collapses at low angle to leading edge, moderate dynamics, total course change <90°, (1), moderate course change rate, low forward pitching <45°, (1), low height loss 20-29m, (1), low sink velocity 10-14 m/s, (1), G-Force < 2,5 G, (1)
Frontal collapse: canopy collapses with low total collapse area, moderate pitch backwards 30-45°, moderate pitch forwards 30-45°, low dynamics, no course change, (1), immediate automatic recovery, symmetric recovery, immediate return to normal airspeed, moderate height loss 30-39 m, (2), low sink velocity 10-14 m/s, (1)
Spiral dives: moderate sink velocity increase, Moderate G-Force 3,5- 4.0 G, (2), Sink velocity after 720° <14 m/s, (1), High maximum sink velocity < 22 m/s, (3), sink velocity increase < 6 m/s on brake release, (2), Course change >720° after spiral exit, (5), moderate height loss during recovery 30-60 m, (2)
B-Stall: normal force required, low pitch backwards <15°, moderate pitch forwards 15-30°, stable sink phase, no tendency to deform, immediate return to normal airspeed, 6-8 m/s, height loss on recovery < 20 m
big ears: simple initiation, stable flight phase, immediate automatic recovery, Vsink unaccelerated 2,5-3 m/s, Vsink accelerated 3-3,5 m/s, Vunaccelerated 5-8 km/h less than trimspeed, Vaccelerated 0-3 km/h faster than trimspeed

Take off behavior: Very easy Asymmetric Collapse: very low dynamik Front Collapse: A collapse over 50% was not possible Spiral Dive: exit of the spiral is very difficult. Acceleration from 13m/s to 18m/s and a stable turning for 720° afterwards a self exit and pitch up in 180°. |

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. |
