would feel a kind of instability and a lack of pressure on the brake lines,
although the canopy would appear to be correctly inflated. The correct
reaction would be to release the pressure on the brake lines and push the
A lines forward or rather lean your body to any side WITHOUT PULLING
ON THE BRAKE LINES.
Deep Stall
The possibility of the HOOK 4 falling into this configuration is almost
nonexistent, if the factory settings have not been altered. This could
happen if you are flying at a very low speed, whilst over steering in a
number of manoeuvres and in turbulent conditions.
To provoke a deep stall you have to take the wing to minimum flight
speed by symmetrically pulling the brake lines, when you reach this
point, continue pulling until you reach 100% and then hold. The glider
will first fall behind you and then situate itself above you, rocking slightly,
depending on how the manoeuvre was carried out. When you start to
provoke a stall, be positive and do not doubt an instant. Do not release
the brake lines when half way through the manoeuvre. This would cause
the glider to surge violently forward with great energy and may result
in the wing below the pilot. It is very important that the pressure on the
brake lines is maintained until the wing is well established vertical above.
To regain normal flight conditions, progressively and symmetrically
release the brake lines, letting the speed be re-established. When the
wing reaches the maximum advanced position ensure that the brakes
are fully released. The wing will now surge forward, this is necessary so
that air speed is completely restored over the wing. Do not over brake
at this point because the wing needs to recover speed to quit the stall
configuration. If you have to control a possible symmetrical front stall,
briefly and symmetrically pull on the brake lines and let go even when the
wing is still ahead of you.
Wing tangle
Of all the possible situations, which you may encounter while flying the
HOOK 4, this is the least probable one of all. The well proportioned ratio
and well calculated positioning of the line cascades ratify this fact.
A wing tangle may happen after an asymmetric collapse, the end of the
wing is trapped between the lines (Cravat). This situation could rapidly
cause the wing to turn, although it depends on the nature of the tangle.
The correction manoeuvres are the same as those applied in the case
of an asymmetrical collapse, control the turn tendency by applying the
opposite brake and lean your body against the turn. Then locate the line
that reaches the stabiliser that is trapped between the other lines. This
line has a different colour and belongs to the external lines of the B riser.
Pull on this line until it is tense, this should help to undo the wing tangle.
If you cannot undo the tangle, fly to the nearest possible landing spot,
control the flying course with your body movements and a little pressure
on the opposite brake. Be careful when attempting to undo a tangle if you
are flying near a mountainside or near to other paragliders, you may lose
control of the flying course and a collision may occur.
Over handling
Most flying incidents are caused by wrong actions of the pilot, which
chained one after another create abnormal flying configurations (a
cascade of incidents). You must to remember that over handling the wing
will lead to critical levels of functioning. The HOOK 4 is designed always
to try to recover normal flight by itself, do not try to over handle it.
Generally speaking, the reactions of the wing, that follow over handling,
are neither due to the input made or the intensity, but the length of time
the pilot continues to over handle. You have to allow the profile to re-
establish normal flight speed after any type of handling.
4.3 USING THE ACCELERATOR
The profile of the HOOK 4 has been designed to fly stable through its
entire speed range, the EN B certification confirms this. It is useful to
accelerate when flying in strong winds or in extreme descending air. When
you accelerate the wing, the profile becomes more sensitive to possible
turbulence and closer to a possible frontal collapse. If you feel a pressure
loss, you should stop pushing on the accelerator and pull slightly on the
brake lines to increase the angle of incidence. Remember that you have to
