Towing And Winching; Asymmetric And Frontal Collapses - Air Design Pure3 Betriebshandbuch

the brakes are fully applied. Avoid landing directly out of a turn or wing-over since your
momentum will be much greater due to the pendulum effect.
Attention:
After touching down, do not allow the glider to dive overhead and fall in front of you. If the
leading edge hits the ground hard, the structure of the cell walls may become damaged.

Towing and Winching

When towing or winching, the glider must be above your head before starting.
In the initial phase the tension should not be too high – a pilot climbing at a flatter angle has
more control.
Tension of more than 90kp is not allowed. In any situation, the maximum permitted tension on
the line must not exceed your weight.
You must be informed and aware of the national requirements for towing. This includes matter
such as: tow/winch licence requirements, qualified tow operators, suitability of glider for
towing, if winch and towing-links are certified etc.
In general, the regulated and enforced regulations must to be followed.

Asymmetric and Frontal Collapses

As with any paraglider, collapses can occur. "Active flying", as described in point "f", can help
avoid deformations.
You should always apply brake on the opposite side to the deflation to stop the rotation. The
glider should be supported in re-inflating by pumping the brake on the collapsed side. Be
aware that the brake travel is shorter when the glider is collapsed and the glider can stall with
less brake input.
If you experience a big collapse while accelerated, release the speed-bar immediately.
To assist in the reopening of a frontal collapse you should pull both brakes equally at the same
time. This also reduces the dive after the glider reopens.
NOTE: Pulling too much brake during a frontal collapse recovery can stall the glider or cause
the glider to revert from the frontal collapse directly into a deep-stall.
ATTENTION:
Due to the strong stability of the PURE3 it is not possible to collapse the wing with the A-risers.
For making collapses (like in a SIV course) it is needed to mount folding lines onto the canopy.
Folding-lines can be requested via AirDesign or your distributor.
NOTE:
We do not recommend trying to make collapses with A-risers.
INFO for safety trainings: when doing collapses during a safety training start pulling down
slowly the folding-lines. The faster the folding-lines are pulled down, the faster the glider
reopens and the more dynamic the reactions are, and therefore the pilots actions are more
demanding. For making accelerated collapses you need much less input on the folding-lines
then compared to trim speed (putting folding lines on tension and then bending the wrist is
enough for making a collapse).
