INSTRUCTIONS FOR EXTREME FLYING AND
DANGEROUS SITUATIONS
DANGEROUS SITUATIONS
Extreme flying with a motor trike and full gas are extremely dangerous and
therefore cannot be tested. They must be avoided at all costs.
Problems do not arise during a normal flight. However, pilot error during the flight
or extreme wind conditions may force the wing into an unusual flying position. This
may require the pilot to make corrections during flight to which he may not be used
to. In this section we explain how to correct extreme situations if they do arise. The
manoeuvres described below are based on the legal -take-off weight as described
in the technical data section.
Note!
These instructions do not replace safety training or specialised literature. We
recommend that you undertake special safety training which will prepare you for
extreme situations.
Always keep within the recommended limits. Do not perform aerobatics or extreme
flying manoeuvres. This will prevent accidents caused by over-loading the glider.
DEEP STALL
Various things can cause a paraglider to deep stall, e.g. shrinkage of the C and D
lines as a result of dampness or flying in the rain. The airflow from the front of the
glider gradually breaks away towards the back and the canopy sags, with the glider
remaining upright. Paragliders are particularly susceptible to deep stalls if the wing
loading is too low. C and D lines which are too short, for example, can often be recognised because
launch behaviour deteriorates. You can recognise a deep stall because there is less flight noise than
normal. In addition, your sink rate will increase (6-8 m/s).
Recovery
The XWing couldn’t be deep-stalled at all during our test flights. The usual recovery
procedure would be to decrease the angle of attack be shortening the A- nd B-
lines. But this would require huge forces at the X-LIGHT. Better would be to decrease
the angle of attack be pulling both trim levers back.
Caution! Accident risk!
A wet canopy or flying in the rain increases the weight of the canopy and may
cause a stall. You are not allowed to fly under these circumstances.
FRONTSTALL
Strong turbulence can cause part or all of the leading edge of the glider to fold or
tuck under. Normally the RelaX will immediately recover into its normal flight position.
RECOVERY
If the XWing does not immediately recover from a frontal tuck, brake quickly and
strongly with both steering-lines (brake lines) to re-inflate the glider.
Any weather condition which causes a front stall is much outside the allowed and
safe weather conditions. If you get into such weather land as soon as possible a
continue not before the weather got quieter!
ASYMMETRICAL TUCKS
In turbulent air, one side of the paraglider may collapse. Some of the cells deflate
and the paraglider may collapse or spin.
During test flights the RelaX self-recovered on release of the A-risers which wer
pulled down to initiate the collapse. It turned less than 90° and stabilised itself.
Recovery
• Counter-brake slightly on the side of the paraglider that is still inflated to
stop it turning away and to stabilise it.
• Counter-brake just enough that the paraglider continues to fly straight
ahead.
• If the wing has not yet self-recovered, pump with the brake on the side th
has collapsed in order to open it, making use of the full brake travel.
