horizontal speed and you are not in control of the paraglider. The air
circulation over the profile is interrupted and the wing enters into a
situation similar to parachuting.
5.3 SPIRAL DIVE
This is a more effective way for rapidly losing height. You have to know
that, the wing can gain a lot of speed and the increase in G’s will be
substantial.
This can cause a loss of orientation and consciousness (blackouts).
These are the reasons why it is best to carry out this manoeuvre
gradually so your capacity to resist the G forces increases and you will
learn to fully appreciate and understand the manoeuvre.
A paraglider flying at its maximum turn speed can reach –20 m/s,
equivalent 70 km/h vertical speed and stabilize in a spiral dive from 15
m/s onwards. These are the reasons why you should be familiar with the
manoeuvre and know how to carry out the exit methods.
This exit manoeuvres have to be carried out gradually and with smooth
movements so you can feel the pressure and speed changes at the same
time.
Practice these movements at sufficient altitude and with moderation.
6. SPECIAL METHODS
6.1 TOWING
The DOBERMANN does not experience any problem whilst being towed.
Only qualified personnel should handle the qualified equipment to carry
out this operation. The wing has to be inflated in the same way as in
normal flight. Glider air speed must be calculated based on wing loading.
6.2 ACROBATIC FLIGHT
Although the DOBERMANN has been tested by expert acrobatic pilots in
extreme situations, it HAS NOT been designed for acrobatic flight and we
DO NOT RECOMMEND THE USE OF THIS GLIDER for that use.
We consider acrobatic flight to be any form of piloting that is different to
normal flight. Extreme manoeuvres take you and your wing to centrifugal
forces that can reach 4 to 5 g. Materials will wear more quickly than in
normal flight.
7. FOLDING INSTRUCTIONS
The DOBERMANN has been equipped with the latest technologies.
Therefore, in order to guarantee the correct preservation of the glider
and to keep it in perfect flying condition, we recommend using always an
appropriate folding method.
The DOBERMANN is delivered with the N-Kare bag. An easy folding
bag that assists you during the folding process and also can be used as
a base surface which protects the glider against damage. More info at

8. CARE AND MAINTENANCE
8.1 MAINTENANCE
Careful maintenance of your equipment will ensure continued
performance.
The fabric and the lines do not need to be washed, if they become dirty,
clean them gently with a soft damp cloth.
If your wing becomes wet with salty water, immerse it in fresh water and
dry it away from direct sunlight.
The sunlight may damage the materials of your wing and cause
