B-Line Stall - Ozone roadster Bedienungsanleitung

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 does not recommend the use of this manoeuvre!
Wingovers
The OZONE Roadster 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,
even cravats 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 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: The pitching movement on exiting the B stall is small but
necessary. We recommend you do not apply brake to the glider until you are
sure that the wing is flying fully again.
The load applied on the B lines during this manoeuvre is not very good for your
wing; only use it in emergency situations.
Spiral Dives
If you turn your Roadster 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 Roadster 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 Roadster 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 Roadster 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 cms 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...
