Only practise this manoeuvre at high altitude and with enough ground
clearance.
To start the manoeuvre, first weight shift and pull the brake handle
located on the inner side of the turn. The intensity of the turn can be
controlled by braking slightly using the outer brake handle. A paraglider
flying at its maximum rotating speed can reach –20 m/s, or the
equivalency of a 70 km/h vertical descent, and will stabilise in a spiral
dive from 15 m/s onwards. Good enough reasons to familiarise yourself
with the manoeuvre and understand how to exit it.
To exit this manoeuvre, the inner brake handle (down side of the turn)
must progressively be relaxed while momentarily applying tension to the
outer brake handle opposite to the turn. The pilot must also weight shift
and lean towards the opposite side of the turn at the same time.
When exiting the spiral, the glider will briefly experience an asymmetrical
acceleration and dive, depending on how the manoeuvre was carried out.
Practise these manoeuvres at sufficient altitude and with moderation.
5.4 SLOW DESCENT TECHNIQUE
This technique allows descent without straining the wing or taxing the
pilot. Glide normally while searching for descending (katabatic) air and
begin to turn as if climbing in a thermal. Beware of potentially dangerous
areas and locate a suitable LZ (landing zone) while descending. Safety
comes first!
6. SPECIAL METHODS
6.1 TOWING
The DOBERMANN 2 does not experience any problem whilst being towed.
Only qualified winch personnel should handle the certified equipment to
carry out this operation. The wing must be inflated similarly as during a
normal mountain or ridge takeoff.
6.2 ACROBATIC FLIGHT
Although the DOBERMANN 2 was tested by expert acrobatic pilots in
extreme situations, it was not designed for it. We do not recommend
using this glider for acrobatic flying!
We consider acrobatic flights to be any form of piloting different than
standard soaring flights. Learning acrobatic manoeuvres should be
conducted under the supervision of qualified instructors within a school
environment and over water with all safety/rescue elements in place.
Forces as high as 4 to 5 G can be exerted on a paragliding wings during
extreme manoeuvres.
Materials will wear more quickly than in normal flight. Gliders subjected
to extreme manoeuvre techniques should be inspected every six months.
7. CARE AND MAINTENANCE
7.1 MAINTENANCE
Careful maintenance of your equipment will ensure continued top
performance.
The fabric and the lines do not need to be washed. If they become dirty,
clean them with a soft damp cloth.
If your wing is wet from contact with salt water, immerse it in fresh water
and dry it away from direct sunlight. Direct sunlight may damage the
wing’s materials and cause premature aging. After landing, do not leave
the wing exposed to the sun. Pack it properly and stow it away in its
backpack.
