Advance acoustic XI 21, Manual

Page: 20 / 46

Steering by the Pitch-Control-System
The XI has a Pitch-Control-System. A Pitch-Control-Line from the
C-Riser also affects the B-Level. When accelerated the XI can be ac-
tively flown and steered by the C/B levels instead of by speed system
and weight shift. Steering with the Pitch-Control-System has the ad-
vantage that handling is more direct.
When accelerated, take hold of the C-risers over the brake popper with
the sides of the hands resting on the line that goes from the C-risers to
the Bs. Make sure you have released your wraps.
Caution: The brake lines must not be tensioned in fully accele-
rated flight
By careful pulling of the C-Risers towards the shoulders, and careful
releasing as well, pitch movements in light turbulence can be opposed.
In addition you can compensate for low canopy pressure by this me-
ans, e.g. when a collapse threatens.
Info: Because of the C-Riser connection to the Bs the pull requi-
red is very high during accelerated flight. This load reduces con-
siderably when a collapse approaches. This is a sign that the ri-
ser must be pulled!
Info: For effective and intuitive C-Riser control a lot of practice is
required. Approach it slowly.
Caution: Pull the C-Risers carefully – not too much. Too much
too fast risks stalling!
Caution: Control by C-Risers is only recommended for gliding in
calm or lightly turbulent air.
