Advance acoustic LIGHTNESS 3, Manual

Page: 38 / 54

Compatibility test
In every case correct installation of a reserve must be proven by a test
release. Put the harness on, close the 2-buckle closure, the Remember
Closure System and the speedbag, and hang the LIGHTNESS 3 up by
its carabiners in a harness stand. Then pull the reserve out by its hand-
le, as if in flight.
It is not sufficient to pull the reserve out when not sitting in the harness
as for flight. The release procedure must take place in the flying posi-
tion, without hindrance, and in accordance with the requirements of
this manual. The force required to release the reserve must not be less
than 4 daN and not more than 7 daN. If in doubt you should contact a
qualified person or your ADVANCE dealer.
The correct throwing technique has to be used – a pull to the side.
Anything else can make deployment more difficult.
The following factors can make successful reserve opening more diffi-
cult, or prevent it – especially if any apply together:
§
Reserve too big – too much volume for the compartment or inner
container.
§
Reserve not folded to the shape of the inner container.
§ Incorrect throwing technique. A pull to the side is required (Caution:
don’t pull the reserve handle straight upwards).
§
The reserve volume was suitable for the harness when first fitted in
the new harness, but after a repack it is too big.
§ Pilot arm length is a factor: short pilots with short arms can so-
metimes not pul out the reserve.
§
Deployment under high g (more than 3g, for example in a spiral dive).
Info: a successful compatibility test can reinforce the tester’s
confidence in the reserve system.
Caution: before every flight check that the reserve handle is
in its correct position, and that the yellow cables are correct-
ly sited.
Tip: We recommend a brief check of the reserve handle during
every flight. This helps to memorise its position. We also advi-
se you to mentally rehearse the sidewards pulling and throwing
action.
