Turning Flight; Brake Line Length; Active Flying - Airdesign Susi 2 Betriebshandbuch Und Serviceheft

d.
Your will notice the very precise handling from the first flight. The SuSi is easy to turn at any
bank angle, from flat through to steeply banked turns. With little brake input the wing turns
flat and therefore climbs well in thermals. With more input the glider becomes agile and more
dynamic allowing radical manoeuvres to be made.
Brake pressure is progressive which enables the pilot to feel the wing and helps prevent
unintentional stalling.
When entering an asymmetric stall (negative): the glider starts to slide into the turn.
The inner wing stops flying, loses pressure and becomes soft. At this point the brakes have to
be released immediately.
In the unlikely event that a brake line releases from the brake handle or breaks, the glider is
manoeuvrable using the C-risers. By pulling gently on the C-risers it is possible to steer the
glider and land safely.
e.
The brake-line length of your new SuSi 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 carry out this process after every 20mm of adjustment.
There should always be free brake travel when the glider is flown hands-up. This means when
you look at your brake lines in flight with your hands up, there should be a slight bow, or arc, to
the line – the brake lines should not be tight. This is to prevent the brakes being applied when
the speed-system is used.
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 SuSi 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.
f.
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.

ATTENTION: PULLING THE BRAKES TOO FAST AND
DEEP INCREASES THE RISK OF STALLING THE WING!
