GIN Boomerang 10 - Manual (Page 13)

13 /62 Boomerang 10
Gin Gliders calculates and draws the plan of the glider with a distance between the carabiners
of 44cm. CCC certification test flights are also carried out with this setting. We recommend
setting a distance of 42cm to 50cm between the carabiners, depending on the size and design of
the harness.
Reclined harnesses
Reclined harnesses are generally completely enclosed and often have a very low main
attachment point. Active flying is very different with them than with an upright harness. To
achieve the same level of efficiency and safety in flight with a reclined harness which you are
accustomed to with an upright harness, you must systematically learn the appropriate
techniques and gain a good deal of experience.
If any problems or disturbances are encountered when flying with a reclined harness, the pilot
must immediately assume an upright seating position. Extreme flight manoeuvres flown in a
reclined position drastically increase the risk of twist. In addition, pilots often underestimate
the reduction in control travel caused by flying an extreme flight manoeuvre.
There is an increased risk of twist when using a reclined harness if a large section of the canopy
collapses. If there is an asymmetric collapse and the pilot tips sideways, the resulting twist
around the vertical axis with a poorly positioned harness leads to a reduction in control travel.
This quickly causes an unintended stall on the open side.
Reserve
It is a mandatory requirement to carry an approved reserve for use in emergency situations
where the paraglider fails and recovery is not possible, for example after colliding with another
aerial sports craft. In choosing a reserve, you should be careful that you remain within the
specified take-off weight. The reserve is fitted according to the manufacturer’s instructions.
Weight Range
Be sure to fly your glider within the certified weight range given in the Technical Specification
section. Due to EPT technology, the Boomerang 10 flies well at any wing loading within this
weight range. If you are choosing between 2 sizes, choose your optimum wing loading according
to your personal preferences and the conditions you fly in.
If you prefer dynamic flight behaviour with fast reactions, you should fly at a high wing-loading,
i.e. choose the smaller model. This may be an advantage in strong, tight thermals.
The dynamics are reduced in the middle and lower part of the weight range. Flight behaviour
becomes more straightforward and many pilots fly with this wing loading because they find it
easier to centre in thermals, especially weaker and wider thermals. If these features appeal to
you, you should fly with a lower wing-loading and choose the larger model.
The Boomerang 10 reacts to weight changes only by slightly increasing or reducing trim speed,
with little noticeable effect on glide performance. You can therefore choose the size completely
according to your own flying style.
