KNOTS IN FLIGHT
The best way to avoid these knots and tangles is to inspect the lines before you inflate
the wing for take-off. If you notice a knot before take off, immediately stop running
and do not take-off.
If you have taken-off with a knot you will have to correct the drift by leaning on the
opposite side of the knot and apply the brake line on that side too. You can gently pull
on the brake line to see if the knot becomes unfastened or try to identify the line with
the knot in it. The identified line can then be pulled to see if the knot undoes. Be very
careful when trying to remove a knot. When there are knots in the lines or when they
are tangled, do not pull too hard on the brake lines because there is a greater risk of the
wing to stalling or negative turn being initiated
Before trying to remove a knot, make sure there are no pilots flying nearby and never
try these manoeuvres near the mountainside. If the knot is too tight and you cannot
remove it, carefully and safely fly to the nearest landing place.

LOSING HEIGHT
The knowledge of the different descent techniques is an important resource to use in
certain situations. The most adequate descent method will depend on the particular
situation.
We recommend that you learn to use these manoeuvres under the tuition of a
competent school.
5.1
BIG EARS
Big ears are a moderate descent method, reaching –3 or –4 m/s, ground speed reduces
slightly between 3 and 5 km/h and piloting becomes limited. The angle of incidence
and the surface wing load also increases. Push on the accelerator to restore the wing’s
horizontal speed and the angle of incidence.
To pull big ears take the outermost A-lines of both stabilizers as high up as possible
and pull on them outward and downward. The wingtips will fold in. Let go of the lines
and the big ears will re-inflate automatically. If they do not re-inflate, gently pull on
one of the brake lines and then on the opposite one. We recommend that you re-inflate
asymmetrically, not to alter the angle of incidence, more so if you are flying near the
ground or flying in turbulence. The ARTIK is fitted with big ear pulleys which makes
both locating the right line and the manoeuvre easier. These big ear pulleys can be
removed whenever the pilot wishes.
