Big ears and spiral dive
Whilst it is possible to enter a spiral dive whilst holding in Big Ears,
the high forces applied to the lower lines could exceed the breaking
strain of the lines leading to equipment failure!
WARNING; Ozone strongly recommends to NOT use this
manoeuvre!
B-Line Stall
B-stall is for fast descents in emergency situations only. B-stall is
performed by symmetrically pulling down on the B-risers.
To initiate the B-stall place your fingers between the lines above
the maillons on the B risers. Do not release the brake handles. As
you pull the B-lines down the airflow over the wing is broken and the
glider loses its forward speed but remains open and you will descend
at around 6 m/s.
If you pull too much B-line the glider will horseshoe and move around
a lot.
To exit the B-stall the B-risers should be released symmetrically and
in one smooth, progressive motion. The glider will resume normal for-
ward flight without further input. Check you have forward flight again
before using the brakes.
IMPORTANT: The pitching movement on exiting the B stall
is small but necessary. We recommend you do not brake
the glider until you are sure that the glider is flying again.
The load applied on the B lines during this manoeuvre is not very good
for your glider, only use it in emergency situations.
Spiral Dives
If you turn your Magnum2 in a series of tightening 360’s it will enter
a spiral dive. This will result in rapid height loss. To initiate a spiral,
look and lean in to the direction you want to go, then smoothly pull
down on the inside brake. The Magnum2 will first turn almost 360
degrees before it drops in to the spiral. Once in the spiral you must
and make small directional adjustments but the major directional
control should still be with weight shift. Be aware that with the ear
blocker system engaged it is possible that the brake range will be re-
duced (higher stall speed) and the roll response of the wing changed.
For this reason you should concentrate on flying the wing carefully
with small, smooth inputs and not use big directional control move-
ments.
IMPORTANT: Practice using the ear system for the first time
in smooth conditions, get used to the action of engaging
and disengaging the line in a smooth controlled manor.
WARNING: With big ears engaged the flying characteristics
of any wing is changed, maintain good airspeed and avoid
deep brake movements or sudden turns. This will reduce
the possibility of entering a stall or spin.
The ears should be released with plenty of altitude; well before your
final landing approach. If you need to perform big ears to lose more
height on approach then do so ‘manually’ - without using the blocker
system.
To release the big ears simply push the line away from the red ball.
Push the A line towards the outside using the palm of your hand,
alternatively you can use your thumb to push the line from the ball
itself. The line will easily slide off the ball and the wing tip will start to
inflate.
If the wing tip does not spontaneously inflate use a small brake input
to encourage it to do so.
Big ears and trimmers
Once the big ears are engaged you can further increase the sink rate
by releasing the trimmers.
