Before your first flight, the hang point should be set using the table below. To do this, loosen the
Velcro on the hang strap, move it and then reattach the Velcro at the new location. Make sure that
the end to which the carabiner is attached is inserted through both loops. Place the desired value in
the middle of the hang strap

Flight Characteristics
6.1.1
Foot Launch
The ATOS-VRS LIGHT is statically slightly rear-heavy on the shoulders. However, after the first few
steps and with sufficient airspeed, it stabilizes at an angle of attack favorable for take-off
.
When
taking the first steps the nose must be actively held down. Choose an angle of attack too flat
rather than too steep, and slightly pull in on the control bar. With a low angle of attack, the
Atos is less susceptible to crosswinds. In addition, the wingtips are further away from the
ground, the spoilers are more effective during the first steps and the risk of a stall is
minimized.
1.
Keep the angle of attack low enough that the wing rests lightly on your shoulders. If
the angle of attack is too low, the wing is difficult to stabilize.
2.
Have a helper hold the wing on the D-spar inside the spoiler wires or at the nose. If
the helper holds the wing further out and pulls down, the pilot has no way of
reducing the angle of attack and can take off uncontrollably. Basically, if a helper is
needed, the conditions are borderline. If in doubt, do not fly!

The values given are guides and should be adjusted to the pilot’s individual preference after the first
few flights (see chapter 6.4)
.
Attention:
The values in the table are set WITHOUT the glider bags inn the D-spar. With bags in
the D-spar, the hang point must be set about 0.2 inches further back. Since the ATOS-VRS LIGHT
reacts sensitively to changes in the center of gravity, AIR recommends stowing the glider bags in the
harness for the first flight.
6.1
Launching
Before the first flight or as training, it is recommended that you practice your take-off run on level
ground. Since the spoilers are so effective, the wing can be controlled even in gusty conditions. This
should be practiced on a level or slightly sloping practice area in appropriate wind conditions .
A flap setting of approx. 10-15° is a good setting for take-off. In this position, the flap bungee sticks
straight out of the keel
.
Tips for strong wind:
The ATOS-VRS LIGHT tows best with flaps set at 10-15°. With this flap setting you can fly slower.
This flap setting lets you climb better in headwinds and makes take-off easier. During the tow, be
sure to maintain sufficient airspeed (basetube approx. at the forehead). Flying too slowly means
loss of performance and less of a safety margin!
