D. Flying techniques
In general the ATIS 3 can be flown conventionally.
The points listed below should help you to familiarize with your new wing even more quickly.
1. Checking the paraglider before take off
• Check the canopy: Check for outer (sail), structural damages (ribs) or damages to the sewing.
• Check the gallery-lines: Check for damages and twists.
• Check the main lines: Check for damages and correct mounting.
• Check the quick links: Quick links must be mounted correctly and securely locked.
• Check the risers: Check for damages and twists.
• Check the brake lines: Check brake lines for free travel and correct length (when flown
with no brake applied the brakes must not deform the canopy).
Brake handles must be linked to the brake lines properly and brake lines must be able
to run freely through their pulleys.

15
2. Take off
We recommend to lay out the glider in a horseshoe shape. This way the central lines
are tensioned first during hoisting. Position yourself in the middle of the canopy before
straightening the lines. Do so by holding your A-risers near the quick links and move forward
until the slack has been taken out of your central main lines evenly.
In nil wind or a slight headwind the ATIS 3 inflates reliably and rises above the pilot
after a few resolute steps with slight tension on the A-risers.
The risers should neither be pushed forward nor pulled down during inflation. It is sufficient
to lead the risers upwards while applying gentle pressure, until the wing has reached its peak
position.
When the canopy is positioned above the pilot, release the risers and accelerate your steps
until liftoff. Watch out to keep your risers tensioned while accelerating by keeping the upper
part of your body (center of gravity) in front of your feet. The take off distance can be reduced
by applying brakes during the last steps.
In case of a strong headwind the canopy might overshoot the pilot.
In this case the wing has to be stopped in its peak position actively by applying brakes.
In these conditions brake input can also shorten the take off distance.

16
3. Landing
The ATIS 3 features a good glide (clear by above 8,5) and fine agile cornering; this has to be
taken into consideration during approach and landing.
Harsh brake-operations are to be avoided during the final approach. We recommend that you
make your first flights with your new ATIS 3 at a well known site with a large landing field.
Pendulum movements and very slow flying should be avoided during landing.
Recommendation: Steer your breaks negatively.
This involves applying 30% of brake symmetrically, then releasing the outside brake.
Sufficient speed upon the last meters of final approach provides a buffer for a clean flair and
a soft landing.

17
4. Turning
The ATIS 3 was designed with comfortable handling and straightforward, stable thermal
behaviour in mind.
Active piloting improves glide and climb and therefore the fun of flying.
"Active flying" means following the movements of the canopy smoothly and avoiding sudden
and harsh movements. Input countering the dynamic of the canopy is to be avoided in any case!
Symmetric brake-input by about 10 to 15% ensures the retention of pressure inside the canopy
and enables you to brake further in case of overshooting or to accelerate the wing when
entering headwind/thermals.
5. Descent procedures
These procedures should only be carried out in suitable surroundings. Avoid crowded areas,
turbulent conditions and thermal or dynamic upwash.
If a descent procedure has to be carried out (e. g. thunderstorm or over-development)
the following techniques can be used:

18
A. Big Ears
• Pull the outmost A-line (or the respective device, if mounted) down, until the wingtip
collapses. We recommend to pull in the ears one by one.
• Hold the lines (or respective device) down to keep the ears collapsed.
• Depending on the size of big ears the sinkrate can increase to 3-4 m/s.
• Operation of the accelerator can improve sink rate and speed.
• You can steer the glider while performing big ears by the weight-shift.
When releasing the lines the ears normally open gently and on their own.
Reopening can be aided by "pumping" the brakes one by one.
Symmetrical brake input to open both ears may lead to a stall.
B. Spiral
The ATIS 3 is a wing featuring fine, precise and progressive cornering behaviour.
To induce a spiral one brake is pulled up to 35 % progressively and held in this position.
Weight shift to the inner side helps, but is not mandatory.

19
Rotational speed in the spiral increases with further brake input. Once in the spiral, speed
and diving angle can be increased or slowed down by varying the brake input by a few centimeters.
With a bit of experience a spiral enables sink rates of more than 10 m/s.
Fast or poorly synchronized brake-input or very steep spirals can lead to asymmetrical collapses
or a flat spin.
Because of high sink rates and a possibly demanding exit we recommend not to perform
this manoeuvre below 100 m above the ground.
Caution: A spiral is not a simple manoevre. The kinetic energy built up must be controlled
by releasing the brakes. Clean entry and exit have to be trained in flying schools
and must be refreshed repeatedly.
C. B-stall
Grasp the B-risers (second riser counted from the front backwards) near the quick links
and pull down symmetrically.
The wing centre will deform slightly and the wing will fall back, then stabilize above the pilot
and provide a sink rate of 6-8 m/s.
Exit the B-stall by symmetrically releasing both B-risers quickly. The ATIS 3 will instantly
adopt trim speed.

20
Pilot errors (releasing risers too slowly), bad trimming or particular conditions (rain) can result
in the wing not adopting trim speed on its own. In this case gently push the accelerator – the ATIS 3
will continously return to normal flight.
If no accelerator bar is mounted pull A-risers symmetrically for about 5 cm.
Caution: A B-stall is a stall, where the canopy does not fly any more.
Perform this manoeuvre at sufficient altitude only.
6. Performance & use of brakes
At 0 % brake (hands up in calm air) the ATIS 3 provides best glide. The speed is 37 to 38
km/h. Minimum sink rate is achieved at 10 to 15 % brake.
Beyond 30% brake, performance figures and the behaviour of ATIS 3 will change; performance
and roll-stability deteriorate and brake pressure increases heavily.
Very heavy brake pressure warns the pilot of an approaching stall-point (100 % brake).
Normally, best performance and maximum security can be found in the first third of brake travel.
