Advance acoustic ZETA User manual

Many thanks for choosing ADVANCE. We
are one of the world’s leading paraglider
manufacturers and are based in Switzerland.
Since 1988 we have consistently followed
our own paths and concepts, both in
development and production. We hope that
your ZETA will bring you many rewarding
hours in the air.
The ZETA is ADVANCE’s most precise and
dynamic wing. It specialises in precision and
performance and its high level of passive
safety means that entry and exit from
all situations are easily mastered. A sprightly
trim speed makes the ZETA exceptionally
suitable for soaring in wind, and thermal
ying is fun as well.
Welcome to ADVANCE

Getting started
This guide gives you a brief look at using
your ZETA, but it does not replace the ofcial
manual, where you will nd detailed instruc-
tions about setting up, ying characteristics,
manoeuvring, upkeep and service.
The manual can be downloaded from
www.advance.ch/zeta.

The ZETA is a wing for pilots who want to get
into freestyle ying, or further develop their
acro skills. The ZETA’s high trim speed also
makes soaring a lot of fun, so this dynamic
glider will very well suit pilots who spend
time in a soaring environment.
The ZETA pilot should have the following
paraglider skills and experience:
• He must be familiar with short brake travel
and high speed.
• He must have secure takeoff and landing
techniques.
• He must be procient at spiral dives
of more than 15m/s sink rate, and be able
to recover without the nal pitch up and
zoom climb.
• He must have a competent active ying
technique.
You as pilot

Every ADVANCE paraglider has to be own
by the dealer before delivery to check for
correct basic settings. Any personal
alteration you make to the paraglider will
result in it losing its certication. The brake
line lengths should not be altered. They are
set at the factory so that, with brakes fully
released, the trailing edge remains unbraked
in accelerated ight.
ZETA delivery includes:
• Speed lines with speedbar
• Inner bag
• Compression strap
• COMFORTPACK
• Repair kit
• Mini windsock
• Getting started booklet

In general a high wing loading means that
dynamic reactions can be expected of a
wing. The ZETA is however straightforward
in nature, and entry into and exit from all
in situations can be well mastered. This
certied ADVANCE Freestyle wing is suitable
for ying the following manoeuvres: Wing-
over, Helicopter, Fullstall, Tail Glide, Looping,
SAT, Asymmetric spiral, Twister, Parachutal
ight, McTwist, Misty Flip, Dynamic Fullstall.
Handling and Manoeuvres

A high wing loading results in a high trim
speed. Internal pressure is similarly raised,
and this again contributes to high dynamic
potential. A raised trim speed is an essential
advantage for ZETA soaring in that soaring
becomes a lot of fun when the wind gets up;
and it often does. The wing’s high stability
and high ZETA passive safety can be of
great value when soaring near the ground.
A small 21 m2wing area makes easy work of
entering a tight circle. Compared with other
products in the category the ZETA has very
good climbing and gliding performance.
ZETA soaring and thermaling are a lot of
fun as well – almost as much fun as freestyle!
Soaring & Thermal flying

Long lines result in the pilot experiencing
high centrifugal loads – g, and this makes
for tons of fun. Along with the additional fun
factor the long lines also encourage the
ZETA to quickly nd itself in a stable spiral.
The ZETA does NOT recover from a steep
spiral by itself. With a neutral sitting position
and released inside brake the wing will
stay in a stable spiral. For this reason it is
essential that a pilot in this situation must
take positive action to recover from a spiral.
Info about the steep spiral dive

Alu Handles as an option
Aluminium handles (acro bars) are available
as an optional extra. These handles make
it easier to apply just the right brake
loads for freestyle manoeuvres. The two
halves of these bars screw together
through the eyelets on the brake handles.

Flying with a wet paraglider
There’s a risk of parachutal stall. Parachutal
stall is often the result of a combination of
factors. The water adds to the weight of the
glider. The additional weight causes a higher
angle of attack, putting the glider closer
to the stall. Then again, water drops on the
wing surface disturb the laminar airow near
the front of the wing, signicantly reducing
the maximum lift coefcient available.
In order to guard against the risk of parachu-
tal stall with a wet wing the glider should
braked as little as possible and big ears
should not be used under any circumstance.
If the glider still goes into parachutal stall
recovery should be achieved by use of the
accelerate system (speedbar) only.

Packing and care
For packing lay the ribs nose on nose, so
that the plastic rods in the leading edge lie
at on each other and all at the same level.
Fold the wing to the width of the inner bag.
Lay the glider on the back surface of the
COMFORTPACK and put the folded harness
on top.
Be aware that bad packing will shorten your
ZETA’s life. Do not leave the glider in the sun
longer than necessary, and never subject
it to large temperature changes. It should be
stored in a dry place.
