ENGLISH
into a spiral dive, once in the spiral you should apply enough outside
brake to keep the outer wing tip pressured and inflated.
Safe descent rates of 8m/s and beyond are possible, the associated
high speeds and G-forces can be disorientating, so pay particular at-
tention 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 R11 deceler-
ates allow it to continue to turn until enough energy is lost for it to
return to level flight without an excessive climb and surge.
You should always be prepared to pilot the wing out of 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
perform this manoeuvre near the ground. Ozone recom-
mends the use of an ANTI G parachute for a more effective
and comfortable spiral dive
INCIDENTS IN FLIGHT
Deflations
If you have a collapse, first priority is to maintain your direction and
fly away from the ground, obstacles and other pilots. Asymmetric
collapses can be controlled by weight shifting away from the collapse
and applying enough brake to control your direction, this act alone will
normally be enough for a full recovery of the wing. In your efforts to
stop the glider turning towards the collapsed side you must be very
careful not to stall the side of the wing that is still flying. If you are
unable to stop the glider turning without exceeding the stall point
EMERGENCY FLIGHT TECHNIQUES
Big Ears
Folding-in the wingtips increases the sink rate whilst maintaining
forward speed, this is useful for staying out of cloud. To pull big ears,
keep hold of your brake handles and take the outermost A-line and
the stabilo line on each side, then pull out down (preferably one at a
time) until the tips of the wing fold under.
Do not use the brakes other than for re-inflation. For directional con-
trol while using the Big Ears, you should use weight shift steering.
To reopen your big ears, release both A lines at the same time. To
help reinflation, brake gently one side at a time until tips regain pres-
sure. Avoid deep symmetric applications of the brake as this could
induce parachutal or full stalls.
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 already
applied. 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!
IMPORTANT: Ozone strongly recommends to NOT use this
manoeuvre!
B-Line Stall
A traditional B line stall is not possible with the Mantra R11
Spiral Dive
The spiral dive is the most effective descent method to lose height
rapidly. The Mantra R11 will turn almost 360 degrees before it drops
