Ozone Mantra M2 Betriebshandbuch Seite 10

To reopen your ears, release the Baby A's: the glider should reopen automatically.
You can still help the reinflation by braking gently, one side at a time, to minimize the
chance of inducing a stall.
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
Although it is possible to enter a spiral dive while holding in Big Ears, the high forces
applied to the lower lines could exceed their breaking strain, leading ultimately to line
failure!
Ozone does not recommend the use of this manoeuvre!
Wingovers
The OZONE Mantra M2 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 both B-risers.
If you pull too much B-line the glider may 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: We do not recommend the use of B line stalls with the Mantra M2.
Pulling too much B line and or turbulence can cause the tips to fly forward and
become unstable. Spiral dive is a safer way to loose height effectively.
Spiral Dives
If you turn your Mantra M2 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 M2 will first turn
almost 360 degrees before it drops into 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 8m/s (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 M2 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 M2 shows no tendency to remain locked in a spiral dive; however
some parameters could interfere with its behaviour. These might include: 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
perform this manoeuvre near the ground.
INCIDENTS
Deep Stall / Parachutal stall
It is possible for gliders to resume their normal shape on a very slow release of the B-
lines, but carry on descending vertically and without full forward motion. This situation
is called 'deep stall' or 'parachutal stall'.
It is unlikely to happen on any OZONE glider, but should it happen, your first reaction
should be to fully raise both brakes and the glider should return to normal flight. If
nothing happens after a few seconds, reach up and push the A-risers forwards or
apply the speed bar to regain normal flight.
Ensure the glider has returned to normal flight (check your airspeed) before you use
the brakes again.
IMPORTANT: only a few centimetres of input from your brakes can maintain
your wing in the stall. Always release your wraps if you have taken them!
Deflations
Due to the flexible form of a paraglider, turbulence may cause a portion of the wing
suddenly to collapse. This can be anything from a small 30% (asymmetric) collapse to
a complete (symmetric) collapse.
If you have a collapse, the first thing to do is to control your direction. You should fly
away from the ground or obstacles and other pilots, or at least not to fly into them...
Asymmetric collapses can be controlled by weight shifting away from the collapse and
applying a small amount of brake to control your direction. This act will most of the
time be enough for a full recovery of the wing.
