32 Section 5 Flying the Sting 2
Given the complexity and the possible risks
of the spiral dive, SWING recommends that
this manoeuvre be learnt under qualified
instruction.
Starting the manoeuvre
Begin the spiral dive whilst flying at full
speed by flying a turn which becomes tighter
and tighter and by using weight- shifting to
the inside (refer here also to the section
“T ”).
The bank angle and sink rate are controlled
by carefully applying or releasing the inside
brake.
Look down before and during the spiral dive
to maintain a constant check on your
distance from the ground.

TIP
The outer wing tip may collapse during
the spiral dive although this is no cause
for concern. It can be avoided by lightly
braking on the outside. Release the
brakes carefully.
Recovery
Recover from the spiral dive slowly and
steadily over several turns, keeping your
body weight in a neutral position. The inside
brakes are gradually released. If the brakes
are released too quickly, the increased
speed can cause the wing to climb, become
unsettled or partly collapse.
Recovery can be assisted by braking lightly
on the outside.
If the glider does not stop turning, this can
be stopped by weight-shifting to the outside
of the turn.
DANGER
At a high sink rate (above 14 m/s) it may
be necessary to brake the outside half of
the wing and/or to use weight-shifting to
recover from the spiral.
Furthermore, for exiting the manoeuvre,
several turns with a corresponding loss of
altitude may be required.
DANGER
You must immediately deploy your
reserve if you lose control of the glider
and the sink rate and find yourself in a
stable spiral.
The spiral may lead to loads and/or
disturbance to consciousness which
prevent later deployment of your reserve.
WARNING
In the spiral dive, very high turn speeds
can be reached with an increase in
acceleration due to gravity (up to over
6g), so exercise care when attempting
this manoeuvre. Take note of the
following:
Carry out your first attempts at spiral
dives under professional instruction as
part of a safety training course.
Do not enter the spiral dive by way of a
wingover. High sink rates can be reached
very quickly by doing this. It is not
possible to gauge the sink rates safely.
Do not continue the spiral dive for too
long: it could cause a loss of
consciousness.
Always maintain ground clearance of
200m . The manoeuvre must be exited at
this height above ground.
