ATTENTION: Due to the high load it demands strong powers to enter control and exit this
manoeuvre!
We do not recommend making this manoeuvre.
n. Deep/Parachutal Stall
The deep stall, or parachutal stall is kind of the pre-stage to a full stall. The wing has no forward
motion and a high sink speed, but it is almost fully inflated. The pilot can enter the deep stall by
applying both brakes. It is very difficult to keep the wing in a deep stall: If you pull the brakes a
little too much, the glider will enter a Full Stall. If you release the brakes too much, the glider
will go back to normal flight. To practice a deep stall, it is necessary to master the full stall first.
A very old or worn out glider with a porous cloth or with a changed trim (due to many winch
launches, or deep spirals) might stay in a deep stall even after releasing both brakes. Do not
apply the brakes in such a situation, because the wing would then enter a full stall! You can exit
the deep stall by pushing the A-risers forward. If you fly through rain, the risk of a deep stall is
higher.
We advise against flying in rainy conditions . If it happens that you get into rainfall, we
recommend not to perform a B-stall or Big Ears. The best is to leave the rain as soon as
possible, and to fly with both brakes released, or even open the trims, as this reduces the risk
of a deep stall. (The available brake travel before entering a deep stall may be reduced
significantly.)
o. Rapid decent manoeuvres
i. Spiral
The spiral dive is an effective way of making a fast descent. During the spiral dive the pilot and
glider will experience strong centrifugal forces which strain the glider. As such it should be
considered an extreme manoeuvre. Due to the rapid height loss during a spiral, pilots must
always take care that they have sufficient altitude before initiating the manoeuvre and that the
airspace is free around the pilot.
Initiation : Weight shift and smoothly pull on one brake (the same side you are weight shifting
into) so the glider goes from a normal 360-degree turn into a steep turn and from there into a
spiral dive. Once established in the spiral the descent rate and bank angle can be controlled
with weight shift and the releasing or pulling of inner brake. As the glider banks in front of the
pilot maintain the spiral by keeping the brake pressure constant, at this point weight-shift can
be neutralised. Descent is controlled by pulling more on the inner brake. A slight pull on the
outside brake helps to keep the glider stable.
Recovery : The RIDE3 recovers from a spiral spontaneously as soon as the brakes are released
and weight shift returns to neutral. To exit, allow the spiral to slow down for a turn or two by
slowly releasing the inner brake. Once the glider starts to exit the spiral, control your descent
rate and bank angle with weight shift and the outer and/or inner brake to prevent any strong
climbs out of spiral. Always finish a spiral dive at a safe altitude.
The RIDE3 does not show any tendency for a stable spiral. That means the glider does not
remain in spiral after releasing the brakes. If the glider should, in rare cases, remain in a stable
