Do not use the brakes other than for re-inflation. For directional
control while using the Big Ears, you should use weight shift steering.
To reopen your big ears, release both baby As at the same time. To
help reinflation, brake gently one side at a time until tips regain
pressure. Avoid deep symmetric applications of the brake as this
could induce parachutal or full stalls.
IMPORTANT : You can land with the ears (you should release
the ears before final flare). But Ozone don't advise you to do
this when it's turbulent or windy due to the risk of a possible
stall and lack of precision in steering.
Big ears and accelerator
Once the big ears are in you can further increase the sink rate by
pushing on the accelerator bar.
NEVER try to pull the Big Ears in with the speed bar on. This can lead
to a major asymmetric deflation.
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!
Ozone do not recommend the use of this manoeuvre!
Wingovers
The OZONE Mantra is not designed for aerobatic flying. The limit is
tightly banked S-turns, commonly known as wingovers. These must
not exceed 90 degrees of bank. Warning: uncoordinated wingovers
can lead to large asymmetric collapses and therefore should never be
executed near the ground.
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
forward 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 Mantra 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 Mantra will first turn almost 360
degrees before it drops in to the spiral. Once in the spiral you must
apply a little outside brake to keep the outer wing tip pressured and
inflated.
Safe descent rates of 8 metres per second (500 ft/min approx.) are
possible in a spiral dive, but at these rates the associated high speeds
and G-forces can be disorientating, so pay particular attention to
your altitude.
To exit the spiral dive, return your weight shift to a central position
and then slowly release the inside brake. As the Mantra decelerates
allow it to continue to turn until enough energy is lost for it to return
to level flight without an excessive climb and surge. The Mantra
shows no indication of remaining neutral in the spiral dive, however
some parameters could interfere with its behaviour such as; wrong
settings of the chest strap (too wide), total weight in flight outside of
the certified weight range, or being in a very deep spiral at a very
high sink rate. You should always be prepared to pilot the wing out
of such a spiral dive. To do so smoothly use opposite weight shift and
apply a small amount of outside brake and the glider will start to
resume normal flight. Never attempt to recover from a spiral with
hard or quick opposite inputs as this will result in an aggressive climb
and surge.
IMPORTANT : Spiral dives with sink rates over 8 m/s are
possible, but should be avoided. They are dangerous and put
unnecessary strain on the glider. Spiral dives cause
disorientation and need time and height to recover. Do not
