Operating limits
The Eden 4 has been tested by certification laboratory European Para Academy to
LTF 1-2 / EN-B category. The Eden 4 is certified for solo flight. The Eden 4 has been
load and shock-tested and passed with a load corresponding to 8G of the maximum
weight in flight 145 kg. Its flying tests have shown that the glider remains stable and
controllable over a wide range of normal and abnormal flight conditions.
Nevertheless, turbulence and gusting winds can lead to a partial or complete
collapse of the canopy. Therefore never fly in such conditions.
Any changes made to this paraglider invalidate the certificate of airworthiness.

Construction of the canopy:
Rigging system:
The canopy of the EDEN 4 consists of 52 cells over the wingspan. The wingtips are
slightly pulled down and this produces a kind of stabilizer. The Eden 4 is a second rib
diagonal-construction paraglider. Every second main rib is attached to the 4 or 5
suspension lines. Between these main suspension ribs, intermediate ribs are
suspended by diagonal segments. These segments do not lead to top surface of canopy
but are attached at 80% of rib's height. This construction ensures a smooth top surface
and precise airfoil reproduction. The internal reinforcements maintain the precise form of
the canopy and provide stability. The cell openings on the under-surface of the profile's
nose provide airflow into the glider. Stretch resistant flares, integrated with diagonal ribs
at the suspension points, ensure an even distribution of load throughout the canopy. A
stretch resistant Mylar strip on the top and bottom panels alongside the openings and
running the length of the trailing edge defines the wingspan, together with an optimized
sail tension; this guarantees a high form stability. Large cross ports allow effective airflow
inside the canopy, providing good re-inflation without reducing the profile accuracy..
The Eden 4 is mainly made of the proven Nylon fabrics Porcher Marine Skytex Rip-stop
9092 E85A, 9017 E38A and 9017 E29A. Like any synthetic material, this can deteriorate
through excessive exposure to UV.
The lines of the Eden 4 are made of proven strong and stretch resistant Polyester HMA
Aramid/Kevlar (yellow core) lines and PES/Dynema (white core) lines. The entire rigging
system comprises individual suspension lines looped and stitched at each end. The
Aramid main lines have strengths from 160 up to 240 kg. The Aramid cascade lines have
strengths from 80kg up to 160 kg. The Dynema brake lines have strengths from 100kg
up to 240 kg
The suspension lines are comprised of “cascaded top lines” (attached to the under-
surface),”cascaded middle lines” (cascade 2 to 2 top lines together on middle main
lines), and “main lines”. Main lines lead to the “quick link” (a Maillon which connects lines
and risers). The “stabilizer lines” connect the upper stabilizer lines on the outer
