When the conditions are turbulent, be more active and anticipate the movements of your
wing, always be aware of your altitude and do not over-react.
We strongly advise you to keep hold of your brakes at all times and to not fly in turbulent
conditions.
Active B Riser control
When gliding, whether at trim speed or in accelerated flight, we recommend to pilot the wing
using the B risers. This gives an improved feel and control over the angle of attack enabling
you to fly actively without using the brakes (which causes drag and pitch movements). The
direct feel allows you to stop collapses before they happen and maintain higher speeds and
higher levels of efficiency.
To fly with the B risers, keep hold of your brake handles (remove any wraps) and take hold
of the wooden handles located on the B risers. Now you have direct control of the AofA; by
pulling the B risers down you increase the AofA, releasing pressure reduces AofA and returns
the wing to trim speed. With B riser control you can fly actively through turbulence, collapses
can be stopped or at least reduced with correct inputs due to the sudden increase in AofA.
If you feel the nose of the wing lose internal pressure, or you see a crease appear between
the A and B line attachment points on the sail you can quickly input the B risers to stop the
collapse occurring. The amount of pressure and size of the input is dependent on the amount
of turbulence, or loss of pressure, but always avoid long deep inputs to avoid inducing large
pitch movements or inadvertent stalls.
During accelerated flight, the added control of active B riser flying further increases the
efficiency and stability of the wing. Whilst accelerated the act of pulling the B risers is exactly
the same as releasing the speed bar. This translates to direct control of speed, AofA, and
internal pressure in your hands. Coupled with active speed bar control, adjustments can
be made with the B risers to optimise your speed and internal pressure through turbulence
helping you to maintain a higher average speed whilst reducing the likelihood of unexpected
