Once the envelope has been raised to the upright position, the inflation tube, all suspension
ropes and all operating lines must be checked. The two holding ropes of the envelope and the
appendix anchor lines must be used to minimize swinging of the envelope during the rest of the
inflation operation.
CAUTION:
If one of the two holding ropes of the envelope positioned itself over the para-
chute while the envelope was rising, it must be removed from this position. Take-
off must not be carried out if there is a holding rope of the envelope lying over the
parachute.
The pull-down line of the inflation socket must be fastened to the load ring with a little slack.
This rules out the risk of injuries to persons if the inflation socket slips out of the appendix. In the
event of windy weather, it may be necessary to stabilize the appendix using the appendix an-
chor lines, if necessary.
CAUTION:
The holding ropes of the envelope and the appendix anchor lines must not be
tied to a heavy object, as this may result in damage to the ropes and to the enve-
lope.
Once inflation has been completed, the Velcro fastener is removed by pulling on the pull-open
line.
When doing this, the pull-down line of the inflation socket must be held tightly
and
the inflation socket must be lowered slowly.
4.6 Making the ropes ready
Check whether the white marking on the parachute line is hanging at the same height as the
lower appendix ring (Poeschel ring). If this is not the case, pull on the parachute and check the
position of the marking again.
The balloon must be deflated if it is not possible to untangle the
parachute line and pull-down belts before take-off.
Check that the appendix closing device is functioning properly. The end of the
appendix pull-
close line
is attached to the rope handle inside the basket. The remaining line is stowed in the
basket bag. The appendix is closed until take-off. For this, the corresponding section of the line
is tied to the rope handle with an easily released knot or wound several times around a toggle
on the load ring.
The
appendix anchor lines
are wound twice around a basket rope and the ends are tied to the
rope handle inside the basket. The remaining line is stowed in the basket bag.
The
parachute line
is untied from the extension line and the end is tied to the rope handle in-
side the basket. From there it runs up to the load ring and the excess length can be wound
around a toggle or stowed in an empty sand bag. The parachute line must always have about
one meter of slack.
