above your head release the risers and keep the handles in your hands, then do 180º turn
to face the slope, run and take off.
IMPORTANT: Never take off when the glider is not fully inflated or falls toward one side.
> landing
Choose a large field clear of all obstructions
& in a clean laminar airflow with an extra
in security in case of making mistakes. Always face the wind when landing.
A different technique is needed for different wind strengths. Every landing should be
judged differently even if it’s your local site.
On final approach the pilot should have hands up (keeping a feel on the wing in case of
unexpected turbulence) so the glider has energy for a flare. In light or nil winds the pilot
will need a committed symmetric flare at around one meter above the ground. When the
wind is strong avoid too much braking to avoid a dangerous situation. Once in the ground
with strong winds run toward the canopy and pull the C risers to avoid being pulled by
the wind.
You must avoid the canopy to fall on its leading edge since the pressure will not escape
and you can brake cells and ribs.

-- asymmetrical tuck/collapse
An asymmetric tuck / collapse is when part (one side) of the wing ( say 20% or even any-
thing up to 90% of the span) tucks or collapses, usually induced by turbulence but some-
times also trough poor pilot control in turns and wing-overs.
The BALI is tested and certified to automatically recover without correction by the pilot,
but with the correct input the pilot can minimize any turning, and height lose, and help
the glider recover more quickly.
There are 3 basic steps to follow immediately if you have a collapse:
1. Weight shift to the flying side of your glider (away from the collapsed side). This helps
stop the rotation
& increases pressure in the wing in the inflated side.
2. If needed apply the correct amount of brake to the open (flying) side to slow any rota-
tion (spiral) induced by the collapse. Be very careful not to use too much brake as its pos-
sible to stall the flying side of the glider, and enter further unstable situations which may
be harder to recover from than the collapse itself.
3. Once the glider has straightened out, or the spiral has slowed, smoothly pull down the brake
on the collapsed side, with a long stroke/pump,
& the deflated side of the glider should re-
inflate. As the glider re-opens release the brake immediately but progressively.
