|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Launch preparations: average
launch characteristics: balanced, delayed climb, needs gentle guidance, good feedback during inflation, little 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 90-180°, (1), moderate course change rate, moderate forward pitching 45-60°, (2), moderate height loss 30-39 m, (2), moderate sink velocity 15-19 m/s, (2), 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), delayed recovery, usually symmetric recovery, delayed return to normal airspeed, short deep stall phase, high height loss 40-49 m, (3), low sink velocity 10-14 m/s, (1)
Spiral dives: moderate sink velocity increase, Low G-Force 3,0- 3,5 G, (1), Sink velocity after 720° <14 m/s, (1), Moderate maximum sink velocity < 18 m/s, (2), sink velocity increase < 3 m/s on brake release, (1), Course change 180-360° after spiral exit, (2), low height loss during recovery < 30 m, (1)
B-Stall: high force required, moderate pitch backwards 15-30°, marked pitch forwards 30-45°, stable sink phase, no tendency to deform, delayed return to normal airspeed < 3 s, 6-8 m/s, height loss on recovery 20-40 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 3-5 km/h less than trimspeed, Vaccelerated 3-5 km/h faster than trimspeed |

Notes |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Start behavior: Slightly delayed rise must be easily performed. Asymmetric Collapses: Its not possible to collapse the glider deep in the test vortex induced collapse with deeper surface depth can cause dynamic reactions. Frontal collapses: Delayed start, short stall phase with collapsed wingtips. B-line stall: Delayed start, short stall phase, then with a clear pitch forward. |

Safety class 3 This class of paraglider react moderately to one or more of the following manoeuvres: frontal collapse, asymmetric collapse or spiral dive.Moderately means that the above manoeuvres result in dynamic reactions from the glider and/or large height losses. Good piloting skills which need to be regularly practised, together with good personal reaction times which are above basic training levels are required to safely fly this class of gliders. Skill and experience levels greater than those attained in basic training are required to safely recover from the above manoeuvres. Emergency descent manoeuvres, in particular spiral dives may require advanced recovery skills. Additional training such as regular ground handling or SIV training is recommended. |
