braked.
Be careful not to get below minimum speed, and don’t overreact with the brakes.
4.3. Turning flight
The IOTA DLS has short and precise brake travel when steering. It responds very directly and progressively to
increasing steering inputs, as soon as brake line free travel has been taken up. Active weight shift effectively
assists steering. Angle of bank can always be increased, stabilised or reduced by brake line load.
The IOTA DLS makes a very agreeable companion in thermals. You do not have to correct for large pitching
movements, and this improves your climbing behaviour – and therefore your performance – significantly. When
thermalling, choose the desired angle of bank and corresponding radius, and try to let the glider turn steadily at
this attitude. Outside brake should be used to steady the wing tip and, in particular, control the rate of turn.
Anything stronger will slow the wingtip down and lose the glider’s good steering qualities.
Warning
To keep good manoeuvrability make sure to fly your IOTA DLS with enough airspeed while
turning in thermals – not too much outside brake.
Info If a brake line breaks the IOTA DLS can be steered by careful use of the C-Handles.
4.4. Accelerated flight
The IOTA DLS wing remains extremely stable even in accelerated flight. However, paragliders operate at a lower
angle of attack while flying at their higher speeds, and the degree of stability is generally reduced. The higher
aerodynamic forces involved at higher airspeeds mean that a collapse can be more dynamic (see also section
“Collapses“).
When encountering severe turbulence while flying accelerated release the speedbar fully before applying the
necessary stabilising brake. The IOTA DLS’s high degree of structural stability allows it to be flown in normally
turbulent air while accelerated. Active speedbar should be employed for adjusting angle of attack under these
conditions, instead of brake. Pitch attitude disturbances can be minimised in this way, and optimal glide
performance can be maintained. See also section “Speedsystem”.
When the angle of attack increases (e.g. wing pitches back when entering lift), the speed bar is briefly pressed
harder when the angle of attack decreases (e.g. wing pitches forward), the speed bar is released.
Warning
Even though the IOTA DLS is very stable in accelerated flight you should only use as much
speedbar as you feel happy with!
Hint
Make sure that brake is not applied at the same time as speed bar, otherwise you will find
yourself in the worst possible gliding situation, without gaining any advantage.
Hint
Always choose a suitable speed for best glide taking into account the actual headwind,
sink rate (descending air) and expected next climb.
