Ozone Swift Six - Spiral Dives

much the glider may deform across the span and the wing tips may move forward. In turbulent air pulling
too much could result in a horseshoe or unstable B stall with the wing moving around above the head. If
this occurs, slowly release the B lines until the wing stabilises or simply exit the B line stall by immediately
releasing the B risers. Do not attempt to maintain a B line stall that is not stable.
To exit, release the B-risers symmetrically in one smooth, progressive motion. The glider will resume
normal forward ight without further input. Always double check you have forward ight before using the
brakes.
Spiral Dives
The spiral dive is the most effective form of rapid descent. If you turn your glider 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 and progressively pull down on the inside brake. The Swift 6 will
rst turn almost 360 degrees before it drops into the spiral. Once in the spiral you should re-centre your
weight shift and apply a little outside brake to keep the outer wing tip pressured and inated.
Safe descent rates of more than 8m/s (1600 ft/min approx.) are possible in a spiral dive, but at these rates
the associated high speeds and g-forces can be disorientating. Always pay particular attention to your
altitude. To exit the spiral dive, smoothly weight shift in the opposite direction of the spiral and smoothly
release the inside brake whilst applying the outside brake. As the Swift 6 decelerates allow it to continue
to turn until enough energy is lost for it to return to level ight without an excessive climb and surge.
It is possible for the Swift 6 to remain neutral in a spiral dive under certain circumstances: unsuitable chest
strap setting (too tight), total weight in ight outside of the certied weight range, or being in a very deep
spiral at a very high sink rate >14m/s.
You should always be prepared to pilot the wing out of a spiral dive. To do so, use opposite weight shift
and smoothly apply enough outside brake until you feel the wing start to decelerate, the glider will then
start to resume normal ight. Recovering from a spiral with hard or quick opposite inputs will result in an
aggressive climb and surge and is not recommended. Always be prepared to manage the energy, bleed
off the speed if necessary. Never perform spiral dives close to the ground.

Always be prepared
to pilot the wing out
of a spiral dive. Use
opposite weight shift
and apply enough
outside brake to
stop the wing from
spiralling.
