4.4.2.1 Laying out the envelope
Lay out the envelope, starting from the basket, with the parachute pointing in the wind direction.
Spread the envelope out widthwise in such a way that the differently colored marking above the
appendix is situated at the center of the upper side of the envelope. Lay the two holding ropes
of the envelope on the left-hand and right-hand sides. Pull out the suspension ropes to their full
length and toggle-fasten them to the load ring.
4.4.2.2 Toggle-fastening the load ring
The suspension rope attached to the load belt above the differently colored marking is the first
to be fastened and is fastened to the load ring at the toggle centrally above the trail rope crow’s-
foot (Fig. 5). Thereafter, pairs of adjacent suspension ropes are each attached to one load ring
toggle leading upwards. The basket ropes are toggle-fastened to the load ring in such a way
that the trail rope crow’s-foot is on the windward side.

It must be ensured that the ropes are not crossed or twisted.
NOTE:
The assignment of the load ring may vary according to the size of the balloon
envelope and that of the basket.
