Flying the NYOS RS
Section 05
25
Turns
With the NYOS RS, SWING has
developed a glider which reacts
immediately to steering input and is
extremely responsive. The NYOS RS
performs best in turns when it is flown
with sufficient speed and weight-
shifting. Too much braking increases the
sink rate.
The NYOS RS has extremely low
negative tendency, so it can also be
turned in a tight area by carefully pulling
the inside brake line.
If the brakes are applied more, the bank
attitude increases and the glider will fly
a fast turn increasing in steepness,
which will eventually become a spiral dive
(further information on this is in the
section “Spiral Dive”).
Landing
There are no specific characteristics to
observe during landing. Prepare for
landing by making a straight approach
flight into the wind and allow the glider
to decelerate at trim speed. At 1m
above the ground, the brake lines are
pulled down as far as they will go, so
that the paraglider has been fully braked
just before the ground is reached.
The brakes should be applied in a more
regulated manner if there is a strong
headwind. Landing out of a steep turn
or a rapid change of direction before
landing should be avoided because of the
pendulum effect caused.
WARNING
Always fly with sufficient speed when
you are near the ground (well above
stall speed) to avoid an unintentional
stall.
Rapid descent methods
WARNING
Any rapid descent methods other
than those described in this section
have not been tested by SWING.
SWING advises against using any
rapid descent methods other than
those described in this section. In an
extreme situation, they could result
in uncontrollable flight positions.
Many flying situations call for a very
rapid descent to avoid a dangerous
situation, e.g. the upcurrent from a
cumulus cloud, an approaching cold
front or a storm front.
Rapid descent methods should all be
practised in calm conditions and at
sufficient altitude so that a pilot is then
able to employ them effectively if
extreme conditions arise. The rapid
descents are divided into three different
manoeuvres which increase the sink
rate in a safe and controllable manner.
Spiral dives
The spiral dive is the most effective
method for making a rapid descent, and
can allow sink rates of up to 20 m/s to
be reached. It is suitable where there is
a high ascent rate and little wind.
The certification tests differentiate
between sink rates over and under 14
m/s. The NYOS RS automatically
recovers from the spiral dive within one
turn up to 14 m/s. Above 14 m/s, it may
be necessary to break the outside half
of the wing and/or weight-shift to the
outside to recover from the spiral. With
a sink rate up to 20 m/s and a neutral
position of the pilot, the spiral does not
tighten automatically.
