General Information about
Flying Parafoil Kites
Introduction to parafoil kites
Parafoil kites are kites without spars which
develop a flight shape similar to paragliders in
air stream. Since they consist only of fabric and
lines they fold to a small size and can easily be
packed for air travel. Parafoil kits haven upper
and lower sail with connectors to give them
a wing shape. These cells either all or some
feature an opening on the inflow side.
The cells themselves are interconnected so that
pressure differences can be balanced inside.
When air streams into the front edge the cells fill
with back pressure higher than the pressures on
the outer surface. This stabilises the shape of the
kite. The lift generated by the low pressure on
the top face is deflected from the lower side onto
the two flying lines through a complex bridle of
lines.
Wind Window (fig. A)
A parafoil kite is flown in the so-called wind win-
dow. The pilot stands with his back downwind,
the wind window in front of the pilot. Depending
on the wind force the wind window is so to
speak a large quarter round.
The parafoil kite can’t be flown outside of this
wind window as the air cells would not be filled
with sufficient air stream.
Power Zone (fig. A)
At the centre of the wind window is the so-called
power zone. In this area straight ahead of the
pilot the strongest air stream should be expected.

The Airfield
Verify the suitability of the airfield (see safety
notices). This area should be free from large
obstacles such as trees or houses. The airfield
must be free from tripping points. These could
not only cause swirling wind but also interfere
with the parafoil kite and also damage it. Large,
open fields or sandy beaches are ideal.
Crashes
Crashes are unavoidable and are part of flying
kites. Many of them appear much worse than
they truly are. However: the stronger the wind
the more violent the crashes! Try to avoid these
if possible. We assume no liability for damage
caused by crashes.
