In general, we shorten others !
In our trim visualisation 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 a 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 larks heads)
- in the maillons
- in the line connections
- to the line attachments points.
We also sometimes replace lines with longer ones, but they are more expensive!
Original dead loops in the maillons
Some clever manufacturers deliver new paragliders with loops in certain maillons or even in certain line connections. If necessary, they can be removed at the first trimming.
Most often, it is not enough and especially…
This allows you to start by “emptying” the rear maillons of their loops before starting to “fill” the maillons of risers A and B.
