Symmetrical or assymmetrical collapses :
The OMEGA 5 conveys a highly satisfying solid feel. An active flying
style will virtually eliminate collapses. Larger collapses (over 50%)
are characterised by a reasonably dynamic turn which is easily
controlled. For these situations we recommend the following :
Weight shift to the open side. Try to rotate with any ensuing turn
so as to reduce the potential for a twist. This also maintains air-
speed and internal pressure promoting a fast reopening. Depending
on the severity of the turn apply brake on the open side so as not to
enter a spiral dive but be aware of creating a potential stall. The object is to
fly the glider in a desirable direction (avoiding obstacles) and then reopen the collapsed side
using a generous pumping action.
Attention : the closures induced by the pilot in calm air can often be more dynamic and are
not exactly the same as the real ones that occur in turbulent air with correct pilot reaction/input.
Fast descents :
To quickly lose height the ADVANCE test team recommends, depending on the situation, a spi-
ral dive or big ears. It is a good idea that you practise these in smooth air. Even flares and lan-
dings with big ears should be practised in smooth conditions so that a serious scenario doesn't
turn into an emergency.
Spiral dive (360) :
The spiral dive is entered into by gradually applying brake on one side. The desired bank angle
is controlled by the amount of brake applied. We advise no weight shifting and to adjust the
harness chest strap width at around 40-45 cm between the karabiners. At the same time the
pilot's head and field of view should be oriented in the direction of the turn. To exit the spiral
raise the inside brake gradually. Depending on the steepness of the spiral it is possible that the
glider could do another rotation even after releasing the brake.
Big ears :
Take the outer suspension line of each A riser and pull them firmly and simultaneously down-
44
wards. Be careful not to pull down on the risers themselves. The wing tips will fold down and
back. Use the brakes to reopen.
NB : do not attempt spiral dives with big ears as this manoeuvre results in extremly high loads
and can unduly stress the glider.
