re-establish the flight speed after correcting the incidence.
It is NOT recommended to accelerate near to the mountainside or in very
turbulent conditions. If necessary you will have to constantly adjust the
movements and pressure on the accelerator whilst constantly adjusting
the pressure applied to the brake lines. This balance is considered to be
“active piloting.”
HOOK 4 has been designed with no other adjustable, removable or
variable device that could modify glider’s behaviour to prevent an incorrect
use of the product.
4.4 FLYING WITHOUT BRAKE LINES
If, for any reason at all, you cannot use the brake lines of your HOOK 4
you will have to pilot the wing using the C-risers and your body weight
to fly towards the nearest landing. The C-lines steer easily because
they are not under pressure, however you have to be careful not to over
handle them causing a stall or negative turn. To land you have to let the
wing fly at full speed and before reaching the ground you will have to
pull symmetrically on both the C-risers. This braking method is not as
effective as using the brake lines so you will land at a higher speed.
4.5 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.
5. 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 SPLIT A
Big ears are a moderate descent method, reaching –3 or –4 m/s, 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.
The HOOK 4 is fitted with a big ear pulley system which makes both
locating the right line and the manoeuvre easier. These big ear pulleys
can easily be removed whenever the pilot wishes. To activate big ears
take either the big ear pulley or outer most line on each A risers (2A3
in the line plan) and simultaneously, smoothly pull 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.
5.2 B-LINE STALL
When you carry out this manoeuvre, the wing stops flying, it loses all
