In general, we shorten others !
On our wedging visualization PDF reports, the values are reduced to 0 for the last row of lines. This makes it easier to read and understand.
So “-12mm” on an A does not mean that the line is too short in absolute terms, but that it is too short compared to the D line of the same group of lines reduced to 0. This is change of repository… and it’s not easy for everyone!
We correct the angle of the ribs by observing the differences A/B/C/D… ignoring their real “altitudes”. Indeed, “variations in altitude” have very little influence on the flight characteristics.
To correct the angle of a rib, we shorten the relatively too long lines by interventions (dead turns and lark’s heads)
- in the maillons
- in the line connections
- to the line attachments points.
We also sometimes replace lines with longer ones, but it is more expensive !
Loops in the maillons of brand new paragliders
Some clever manufacturers deliver the canopies new with loops in the rear riser maillons. If necessary, they can be removed at the first trimming.
More often than not, it’s not enough and above all it’s never precise enough to put things back on track.
This allows you to start by “emptying” the back maillons of their loops before you start to “fill” the A and B riser maillons.
