It should be concertina-packed, with the leading edge reinforcements flat
and the flexible rods stacked one on top of the other. This method will
keep the profile in its original shape and protect the integrity of the wing
over time. Make sure the reinforcements are not bent or folded. It should
not be folded too tightly to avoid damage to the cloth and/or lines.
At Niviuk we have designed the NKare Bag, a bag designed to assist you
with rapid packing which helps maintain the integrity of the leading edge
and its internal structures in perfect condition.
The NKare Bag guides you through the folding process, allowing you to
concertina pack the wing with each rod on top of the other and then fold
the wing as required. This folding system ensures that both the fabric and
the reinforcements of the internal structure are kept in perfect condition.
4. IN FLIGHT
4.1 FLYING IN TURBULENCE
We recommend that you read the certification test report.
The report contains all the necessary information on how the ICEPEAK
EVOX reacts during each of the tested manoeuvres.
It is important to point out that the appropriate response to each adverse
manoeuver can vary from size to size; even within the same size at
maximum or minimum load the behaviour and reactions of the wing may
vary.
Having the knowledge that the testing house provides through the test
report is fundamental to learning how to deal with possible situations.
To become familiar with the manoeuvres described below, we recommend
practising within the auspices of a licensed training outfit.
4.2 POSSIBLE CONFIGURATIONS
To become familiar with the manoeuvres described below, we recommend
practising within the environment of a licensed training outfit. You must
adapt your use of the brakes depending on the wing-loading and avoid
over-steering.
It is important to note that the type of reaction to a manoeuvre can vary
from one size of wing to another, and even within the same size the
behaviour and reactions may be different depending on the wing-loading.
In the test report, you will find all the necessary information on how to
handle your new wing during each of the tested manoeuvres. Having this
information is crucial to know how to react during these manoeuvres in
real flight, so you can deal with these situations as safely as possible.
Asymmetric collapse
In spite of the ICEPEAK EVOX’s profile stability, strong turbulent air may
cause the wing to collapse asymmetrically in very strong turbulence,
especially if you do not fly actively and prevent the collapse. In this
case the glider conveys a loss of pressure through the brake lines and
the harness. To prevent the collapse from happening, pull the brake
handle on the affected side of the wing. It will increase the incidence of
the wing (angle of attack). If the collapse does happen, the ICEPEAK
EVOX will not react violently, the turning tendency is gradual and easily
controlled. Weight-shift toward the open, flying side (the opposite side of
the collapse) to keep the wing flying straight, while applying light brake
pressure to that side if necessary. Normally, the collapsed side of the wing
should then recover and reopen by itself. If it does not, try to weight-shift
towards the collapsed side. If this does not resolve the issue, pull the
brake handle on the collapsed side decisively and quickly all the way
(100%) down and release it back up immediately. You may have to repeat
this action to provoke the re-opening of the collapsed glider side. Do not
over-brake or slow down the flying side of the wing (control the turn).
Once the collapsed side is open make sure you return to normal flying
speed.
