d. Turning flight
The UFO 2 has got a very agile handling.
Brake pressure is progressive which enables the pilot to feel the wing and helps prevent
unintentional stalling.
Because of the agile response on brakes we recommend when flying in thermals only using as
little brake input as needed. Pulling too much on brakes placed the wing too steep in the
thermal and loosing therefore climbing performance. Eventually, it is also helpful to shift the
outer brake further off (towards wing-tip) for flatter turning. We call this brake-shifting.
brake-shifting
The webbing attachment for the brake-line pulley is intentionally long making it possible to
move the brake handle either to the inside or outside of the riser.
For example: if the glider turns flat: make a steeper or faster turn by moving the inside hand
towards the centre of wing. The glider then speeds up in the turn and the angle of bank
becomes steeper. When doing the opposite
– moving the arms away from the body - the glider
turns flatter and the climb becomes more efficient. We call it “brake - shifting”.
ATTENTION: PULLING THE BRAKES TOO FAST AND
DEEP INCREASES THE RISK OF STALLING THE WING!
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. Brake line length
The brake-line length of your new UFO 2 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.
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.
