The suspension lines are comprised of “cascaded top lines” (attached to the under-
surface) and “main lines”. Main lines lead loop of riser`s straps or to the “quick link”
(a Maillon which connects lines and risers). The “stabilizer lines” connect the upper
stabilizer lines on the outer suspension points with the quick link. The”brake lines” are
not load carrying suspension lines. They lead from the trailing edge of the canopy to the
main brake lines and run through the pulleys on the D-risers to the brake handles. A
mark on the main brake line indicates the position of the brake handle. This adjustment,
on the one hand, allows sufficient brake to be applied during extreme flying situations
and when landing, while on the other hand, this ensures that brakes are not
permanently applied to the canopy (especially when fully accelerated). This trimming
should not be altered. For differentiation purposes the A-lines are coloured red, the
brake lines are orange, all remaining lines are yellow. Also the main suspension loop,
on the bottom of the riser, is covered red. This is where the main karabiner should be
hooked in, which then in turn connects the risers to the harness.
The Yukon is equipped with 4 strap risers per side (A, B, C, D). The 3 A-main lines per
side are attached to the A-strap. The 3 B-main lines and the stabilizer lines are attached
to the B-strap. The 3 C-main lines to the C-strap. The 3 D-main lines to the D-strap. The
main brake lines leads through the pulleys on the D-strap.
The line connections are made to riser`s strap loops. Second option: The line
connections are made to triangular Maillons (quick links) fitted with a rubber ”o- ring” in
the form of a ”figure eight” which prevents any slipping of the lines on the quick link.
See line plan for details
Speed system:
The Yukon is equipped with a stirrup operated speed-system, which returns
automatically to normal position when the stirrup is released. The serial risers of the
Yukon do not have a lockable trimmer.
The speed system affects the A-, B- and C-risers and changes the angle of attack. In
normal flight all risers have an overall length of 50 cm without quick links. When the
stirrup is pushed out the A-risers are shortened by up to a maximum of 16 cm, the B-
risers by up to a max. of 14 cm, the C-risers by up to a max. of 7 cm, the D-risers retain
their original length. These measurements influence the certification! An incorrectly fitted
speed system causes loss of certification!
