Other adjustments or changes to your UFO 2 lead to a loss of warranty, airworthiness and
validity of certification and may endanger both yourself and others.
f. Active flying
Flying actively improves the safety. Flying with a little brake applied equally will slightly
increase the angle of attack and help to prevent deflations and allow the pilot to experience
more direct feedback. This allows the pilot to feel the air and the glider which can help prevent
collapses.
The aim of active flying is to keep the glider above the pilot’s head in all situations by
responding correctly to the glider's movements using the brakes and weight shift.
When entering a strong or rough thermal it is important that the glider is not too far back or
able to enter a dynamic stall. To avoid this, it is often helpful to release the brakes slightly
when entering, which gives the glider a little more speed. Equally, when exiting a strong climb
it may be necessary to brake more to prevent the glider from diving forward.
g. Accelerating
The speed system on the UFO 2 comes supplied with ‘quick hooks’ ready to attach to a speed
bar of choice. The complete speed system should be checked to ensure it runs smoothly by
hanging in the harness before flying.
In particular, check that the speed system won’t be engaged when in normal flight.
Unnecessary knots and loops in a speed system are not recommended.
When pushing the speed bar the angle of attack of the glider is reduced. The glider speeds up
but at the same time is more sensitive to deformation.
In spite of the exceptional stability of the UFO 2, any accelerated collapse will be more dynamic
than the same event experienced at trim speed and will require quicker reactions to maintain
normal flight.
Always keep both hands on the controls when flying fast or in turbulence and be ready to
release the speed system immediately at the first sign of a collapse.
When flying through strong sink or into a headwind it is useful to fly faster using the speedbar.
Use the speed system carefully when flying close to the terrain and maintain enough height
from the ground or other obstacles to recover in the event of a collapse.
