Contrary to Nicolas Brenneur, I don’t think that all the lines are getting shorter, but it doesn’t matter, because we agree that the deformations must be corrected to bring the lines back into conformity with the certification !
We take everything into account, from the riser to the line attachment and a few mm here and there end up being a few cm !
The novelty for me is that the A’s are often longer (or less short!) than the B’s. We find differences of 15 mm on new canopies after a few dozen hours of flight.
15 mm between A and B on today’s performance wing is huge !
A priori, this is due to the fact that the lift is located further forward on recent profiles.
