Accelerated flight
The BIBETA 6 canopy remains very stable even when accelerated . At
their upper speed range however, paragliders fly at a lower angle of at-
tack, and are generally considered to be less structurally stable at high
speed . Because of the higher forces and energy, collapses at high
speed are more dynamic . See also section “Collapses” .
§
You can fly through light turbulence while accelerated thanks to the
BIBETA 6‘s high canopy stability .
§
With open trimmers you can also control and stabilise the BIBETA 6
with the brakes in turbulence .
Caution:
With open trimmers the steering/braking hand position
is significantly displaced upwards, and brake force increases
due to the higher airspeed .
Tip:
We recommend that you circle in thermals with closed trim-
mers . You will then be flying closer to best stability and minimum
sink configurations .
Collapses
Asymmetric collapse of the wing
The BIBETA 6 is notable for its very solid and stiff canopy . With an ac-
tive flying technique in normal conditions collapses should be more or
less completely avoidable .
If, however, the glider should suffer a greater-than-50 % asymmetric
collapse at trim speed the reaction will only be a slight turning tenden-
cy, and track can be maintained without problem by means of light
braking . Under normal conditions the wing will open by itself .
An asymmetric collapse in accelerated flight will produce a slightly
more impulsive reaction due to the higher aerodynamic forces involved
at the higher speed . The turning away behaviour at a collapse at fully
accelerated speed is a little more dynamic, but is well manageable .
After an asymmetric collapse direction should be maintained by care-
ful opposite braking, and wing pressure raised on the collapsed side
by brake pumping . This will quicken canopy reopening . Only use just
enough brake on the open side so as not to stall this wing .
Poorly flown wingovers can make the wing tips fold in and cause a cra-
vat . Because of the high drag that they produce at the wingtip cravats
can cause a strong rotation moment (=spiralling) . Oppose this desire
to rotate with careful use of opposite brake . Then clear the cravat by
