compared to conventional gliders. The stall-point position is noticeable via a softened feel. The
UFO recovers immediately with a short, fast dive, but stops itself at around 45 degrees.
(The publication of the brake travel is claimed by the EN 926-2.)
It would be dangerous to use the brake travel according to those numbers, because it is not
practicable to measure the brake travel during flight, and in turbulences the stall might occur
with less or more brake travel.
The brake-line length of your new UFO has been finely tuned by AIRDESIGN test pilots, and it
should not be necessary to adjust it.
If you feel it is necessary to adjust the brake-line length to suit physical build, height of harness
hang points, or style of flying, we recommend you ground handle the glider before you test-fly
it, and repeat this process after every 20mm of adjustment.
Brake lines that are too short:

May lead to fatigue from flying with your hands in an unnatural position

May impede recovery from certain manoeuvres

Will certainly reduce your glider's speed range.
Brake lines that are too long will:

Reduce pilot control during launch

Reduce control in extreme flying situations

Make it difficult to execute a good flare when landing.
Each brake line should be tied securely to its control handle with a suitable knot.
Other adjustments or changes to your UFO lead to a loss of warranty, airworthiness and
validity of certification, and may endanger both yourself and others.
If you have any suggestions for improvements let us know, and our test pilots will try out your
ideas in a controlled situation.
Alternative Steering:
In the unlikely event, that a brake line releases from the brake handle, or breaks, or the brake-
lines are tangled up, the glider is manoeuvrable using the rear-risers. By pulling gently on the
rear-risers, it is possible to steer the glider and land safely. Don’t pull the rear-risers too much,
to avoid a deep stall!
e. Active flying
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.
