6. INSTRUCTIONS FOR EXTREME FLYING AND DANGEROUS SITUATIONS
The NAJA was specifically designed for use in motorised flight.
The DULV regulations were the basis for our new product, because the safety
requirements for a paramotor wing are different from those for a wing used for
thermalling.
Even though numerous test flights during the development work were carried out
without using a motor, we specifically do not recommend the NAJA for free flight. It does
not have the appropriate certification for free flight.
Pilot error during the flight or extreme wind conditions may leave the wing in an unusual
flying position. This may require the pilot to make corrections during flight to which he is
unaccustomed.
In this section we explain how to correct any extreme situations you may get into. The
manoeuvres described below relate to the DULV take-off weight and should help to
understand the behaviour of the NAJA.
Tip
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.
We were not able to put the NAJA into a deep stall during test flights.
However 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.
It is often possible to recognise that C and D lines are too short, for example, 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 (4-5 m/s).
Open the trimmers. If this is not possible or if the paraglider does not speed up
immediately, take hold of the A-risers from outside (palms facing in the direction you are
flying) and shorten them by twisting them by about 90° forwards. Do not under any
circumstances accelerate when doing this.
Caution – accident risk.
A wet canopy or flying in the rain increase the canopy weight and can in some
circumstances cause a deep stall. Flying is forbidden in these situations.
Strong turbulence can cause part or all of the leading edge of the glider to fold or tuck
under.
Normally the NAJA will immediately recover its normal flight position.
Front stalls can affect a larger surface area if the trimmers are open. A short
symmetrical braking action is required to reopen the glider, particularly if there is low
wing-loading. The brakes must be completely released after the glider has reinflated so
that it can continue flying again.
