CLOSURES
The reopening, on this model, is very generally spontaneous and
immediate, especially if the pilot takes care and flies with some braking when
the conditions are likely to cause closures.
Even though the likelihood of this has not been shown during the tests, it
cannot be excluded that after a massive closure which causes a turn, if nothing
is done, it could degenerate into auto-rotation .
To correct for this the pilot should transfer his weight to the inflated side and
brake on the outside of the turn. Once the rotation has been stopped, if the
wing has not already reopened, pull on both controls briefly and simultaneously
to open it, without slowing the wing excessively to avoid a stall.
A DEFLATION, EVEN PARTIAL, CAN NEVER BE CONSIDERED
ACCEPTABLE AND THE FLIGHT SHOULD CAREFULLY BE SHORTENED.
RADICAL MANOEUVRES
Radical manoeuvres should be avoided. They have been done during
the numerous test flights but are not within the normal flying limits of a
paraglider.
- wingovers with more roll than 45° either side of the vertical,
- slowing and then releasing the controls producing pitching movement
Greater than 30° either side of the vertical,
- Stalling manoeuvres,
- sudden turns at very low speed, susceptible of degenerating into flat
spin or asymmetric stalls,
- closing manoeuvres using the risers.
The ALTEA was tested in flight equipped with a Standard" ABS" SUP'
AIR harness. (Attachment height of 42 cm. Front strap tightened 50%, distance
between the carabiners 38 - 42 cm).The stabilising effect of this harness with a
roll damping system, depends mainly on a correct adjustment of the whole
harness including the front strap, the dorsal straps and the shoulder straps.
During the period of familiarisation with the wing, and afterwards, if one hopes
to favour the spontaneous re-inflation characteristics, one should make sure
that all the straps are precisely adjusted, so that the carabiners connecting the
harness to the risers are as close as possible to the chest whilst remaining
sufficiently apart :
- front strap tightened 50%.
- dorsal straps adjusted to produce a vertical upper body without being
uncomfortable.
- The shoulder straps are adjusted from take-off .
