B-Line Stall; Deep Stall / Parachutal Stall; Spiral Dives - Ozone Mcdaddy 44 Betriebshandbuch

Decent Techniques
Wingovers
The OZONE McDaddy is not designed for aerobatic flying. The limit is
tightly banked S-turns, commonly known as wingovers. These must
not exceed 45 degrees of bank. Warning: uncoordinated wingovers
can lead to large asymmetric collapses and therefore should never be
executed near the ground.
Big Ears
Folding in the wingtips of the McDaddy increases its sink rate. This is
useful for staying out of cloud or descending quickly. To pull big ears
on the McDaddy take the outermost A-line and pull it down until the
tips of the wing fold under. OZONE gliders are fitted with split A-risers
to make this procedure easy.
Remember that once the Big Ears are in, you have less wing area
supporting you so your stall speed will have increased.
Do not use the brakes other than for re-inflation. For directional
control while using the Big Ears, you should use weight shift.
To reopen the wing tips, release the outer A line, normally the tips
will re-inflate automatically. You can help the process by leaning
away from the side you want to re-inflate and gently pumping the
brakes. Do this one side at a time to minimise the chance of inducing
a stall.
WARNING: Do not use Big Ears 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. It takes a
lot of force to B-line the McDaddy as the B2 tabs spread the load and
you have to pull a wide area of the sail in. However, the way the B2's
spread the load means that there is much less strain on the glider
when in the B- stall, and therefore less chance of damaging your
wing.
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.

Deep Stall / Parachutal stall

It is possible for gliders to resume their normal shape on 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 highly unlikely to happen on any OZONE glider, but should it
happen, reach up and push the A-risers forwards until normal flight
returns. Only then should you use the brakes again.

Spiral Dives

If you turn your McDaddy in a series of tightening 360's it will enter
a spiral dive. This will result 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 McDaddy 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 these high speeds and G-forces can be
disorientating, so pay particular attention to your altitude.
To exit the spiral dive, slowly release the inside brake and apply a
small amount of outside brake. As the McDaddy decelerates allow it
