tips will fold down and back. If you let the baby risers free, the glider
will reopen immediately.
Don't rely on this fast decent method if your glider is wet - more in-
formation is found in the relevant section. Another point to note du-
ring Big Ears is that the trailing edge should be crease free and thus
unbraked. If too much brake is evident the risk of a stall is heightened.
Do not attempt spiral dives with big ears as this manoeuvre results in
extremely high loads and can unduly stress the glider.
Using speed system with Big Ears
In order to quickly reduce height and fl y away from danger we recom-
mend the following:
Place your feet on the speed system. Apply big ears. This will symme-
trically collapse 1/3 of the leading edge and reduce the angle of attack.
Apply speed bar to the desired point and steer using weight shift.
Spiral dive (360)
We advise no weight shifting and to adjust the harness chest strap
width at around 40-42 cm between the karabiners.
Initiate the spiral dive by progressive pulling on one control line. The
head and the angle of view should be oriented in the direction of the
turn. Both rotational speed and centrifugal force increase with a gro-
wing angle of bank.

The response of the glider can be divided into two phases. At fi rst, af-
ter fl at turns, the glider begins to turn in an ever-decreasing radi-
us with an increasing angle of bank. In the second phase, the glider
goes deeper into the spiral, that is to say the wing tilts on its nose with
additional acceleration. Try to retain a neutral sitting position, that
is to say surrender to the centrifugal force - your body will be drawn
outwards.
From the neutral sitting position, the manoeuvre is completed by pro-
gressive release of the control line on the inside of the curve. With
spiral dives involving rapid descent and high rotational speed, a gra-
dual release is essential. In this way you can prevent an excessive en-
ergy retention climb out followed by overshooting.
Ensure that you have adequate altitude in which to recover from the
spiral; as a general rule you need to allow as much time again as the
time you take to initiate the spiral!
Bear in mind that a sitting position with active weight transfer to the
inside of the curve leads to increased acceleration and stable further
turning. For successful recovery, counter-braking is necessary with
simultaneous weight transfer (push your body outwards). All glider
reactions known to us are based on experience gathered during nu-
merous test fl ights with ADVANCE harnesses (harness group GH /
