Pilot skill requirements:
Pilots should be able to recognise the onset of instability and be able to prevent or minimise glider reactions through immediate and precise pilot inputs.
Expert piloting skills and regular flight practice (>50 hour per year) necessary.

Glider characteristics

Launch preparations: average
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, high dynamics, total course change 180-270°, (3), fast course change rate, marked forward pitching 60-75°, (4), very high height loss 50-59 m, (4), low sink velocity 10-14 m/s, (1), collapse on opposite wingtip with course change >90°, (5), G-Force 2,5- 2,9 G, (2)
Frontal collapse: moderate pitch backwards 30-45°, moderate pitch forwards 30-45°, moderate dynamics, no course change, (1), variable recovery behaviour, at times immediate, at times delayed, automatic recovery, (3), symmetric recovery, horseshoe, wingtips at rear, immediate return to normal airspeed, very high height loss >50 m, (4), low sink velocity 10-14 m/s, (1)
Spiral dives: rapid sink velocity increase, High G-Force 4,0-4,5 G, (3), 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 360-540° after spiral exit, (3), high height loss during recovery 60-100 m, (3)
B-Stall: normal force required, high pitch backwards 45-60°, moderate pitch forwards 15-30°, stable sink phase, no tendency to deform, immediate return to normal airspeed, 8-10 m/s, height loss on recovery 20-40 m
big ears: simple initiation, stable flight phase, wingtips flatter a little, immediate automatic recovery, Vsink unaccelerated 2,5-3 m/s, Vsink accelerated 3-3,5 m/s, Vunaccelerated 3-5 km/h less than trimspeed, Vaccelerated 0-3 km/h faster than trimspeed
Steering behaviour: balanced to agile, very noticable brake pressure increasse, Late stall point, easily identifiable

Notes

en:

Side collapse:
It was difficult to deform the wing with a deep surface and a steep bend line. After folding the glider turns quickly and nods forward, while the change of course is total at 180-270 degrees. The glider has the tendency that the open outer wing curling in at stabilo and the rotation and pitching motion stops. During big collapses (upper limit of the measuring field), the glider has a tendency to against side collapses, which were then also very large. It came about to change in direction> 90 degrees. Break open collapses happen two times in the test. This led after break open to a renewed collapse on this side without big dynamic. The break open happens in the act of nodding forward.

Front collapse:
it was very difficult to generate surface deep front collapse. The glider opens mostly starting from the center and goes on immediately. The ears open slightly delayed and independently. In frontal collapses with a very large surface depth occurred at the starting weight lower limit to delayed opening with height loss more than 50 m.

Spiral Dive:
Spiral is easy to control and typical for this class, if the pilot, according to test requirements, the centrifugal force does not counteract. Tendency exists to stable spiral when the pilot remains in the weight shift to the curve side or in the neutral position. SAT-spiral is possible.

Ears:
Easy, light hitting the folded wingtips.

B-Stall:
Easy, force high.

Full stall:
Easy. No special technology needed. Beautiful, long-lasting pre-fill phase.



















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.
