Safety class 3
Pilot skill requirements:
Recovery techniques and experience levels greater than those learned in initial training.
SIV training recommended.
Regular flight practice.

Glider characteristics
Launch preparations: average
launch characteristics: balanced, climbs constantly, no guidance necessary, good feedback during inflation, little braking required, slows before zenith, control check simple, low takeoff speed
asymmetric collapse: moderate dynamics, total course change 180-270°, (3), moderate course change rate, moderate forward pitching 45-60°, (2), high height loss 40-49 m, (3), moderate sink velocity 15-19 m/s, (2), G-Force < 2,5 G, (1)
Frontal collapse: canopy collapses with low total collapse area, low pitch backwards <30°, moderate pitch forwards 30-45°, moderate dynamics, no course change, (1), delayed recovery, usually symmetric recovery, delayed return to normal airspeed, delayed reinflation of wingtips, high height loss 40-49 m, (3), low sink velocity 10-14 m/s, (1)
Spiral dives: very rapid sink velocity increase, Moderate G-Force 3,5- 4.0 G, (2), Sink velocity after 720° <18 m/s, (3), High maximum sink velocity < 22 m/s, (3), sink velocity increase < 6 m/s on brake release, (2), Course change 180-360° after spiral exit, (2), moderate height loss during recovery 30-60 m, (2)
B-Stall: normal force required, moderate pitch backwards 15-30°, low pitch forwards <15°, 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 3,5-4 m/s, Vunaccelerated 3-5 km/h less than trimspeed, Vaccelerated 3-5 km/h faster than trimspeed

Notes
Launch Characteristic:
Four of the five LTF-A gliders demonstrated good school suitability in terms of launching the glider. For this segment it is particularly important that gliders do not tend to overshoot, as this quickly over-challenges new pilots. Niviuk Koyot 2, Icaro Cyber TE, Nova Susi and Ozone Mojo 4 are all excellent here. Their canopies climb steadily with comfortable pressure on the A-risers and slow automatically as the reach the zenith. Only moderate brake appliance is necessary to stabilise them.

Asymmetric Collapse:
Mojo 4 and Koyot 2 change course to a greater degree and suffer more height loss than the other test gliders.

Front Collapse:
Ozones Mojo 4 opens first in the middle, but the ears stay closed with sink velocities of
about 5 m/s for a period before recovering completely. Sink rates are relatively low for the Mojo 4 even for large collapses.

Spiral Dive:
Relatively dynamic transition from entry to spiral, with rapid increase in sink rate and G-force.
Exit relatively simple.

B-Stall:
Very stable sink phase, low pitch forward on exit.
The LTF-A gliders Nova SuSi, Icaro CyberTE, Ozone Mojo 4, Niviuk Koyot and the low end LTF-B Swing Arcus 7 and Air Design Vita displayed good behaviour in B-stalls. No deformation tendencies, stable sink phase with good sink rates and no recovery or deep stall problems on exiting

Big Ears:
Performing big ears was unproblematic.

Rating

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.
