Bulky reserves of an older generation can be relatively difficult to release from compact, modern harnesses,
especially under high-G circumstances. Certified volumes of reserves for the BIPRO 4 reserve compartment are a
function of harness size: M: 5.0 - 9.0 liters, L: 5.0 - 9.0 liters.
Info
For a broad approximation for reserve volume in liters a factor of x 2.7 can be applied to
the reserve weight in kgs. Depending on method and packing skill a reserve with a volume
arrived at by this formula, which is within the certified limits for a harness, still may not
release without problems.
Warning
If a reserve volume lies within the top third of the certified volume, special care must be
taken that the reserve is folded to match the length of the inner container‘s longest side.
Warning
In every case a test release/compatibility test carried out by the pilot in realistic
conditions is the only way to prove that the particular reserve will reliably release from
the
BIPRO 4
.
Warning
A newly-folded reserve can occupy up to 30% greater volume. ADVANCE strongly
recommend a compatibility test.
Steerable reserves
The BIPRO 4 is not suitable for steerable reserves.
Info
It is not possible to install quick-out carabiners.
4.2.1. Packing the reserve in the inner container
General
The release handle and the five-flap inner container are connected and designed in such a way that the pull from
the release handle is evenly distributed over the entire width of the inner container. This reduces the risk of the
inner container jamming in the reserve compartment and of reserve lines entangling with the inner container, and
guarantees optimal deployment. The release handle used with the five-flap inner container is part of the harness
and complies with the latest certification requirements according to NfL.
Warning
Only use the original reserve handle and its attached inner container.
Packing the reserve parachute in the inner container
Always pack your reserve parachute to fit the shape and size of the supplied inner container. Place the rescue lines
in the back in the direction of flight/throw. When all lines are stowed, there should be about 90 cm of line length
left to the bridle.
Warning
If your reserve parachute does not fit in the inner container without excessive squeezing,
this indicates that it is too big for the BIPRO 4.
