Turning Flight; Accelerated Flight - Advance acoustic IOTA 23 User Manual

It is often more efficient to disregard minor pitching rather than correct
it by overcontrolling with the brakes . The test team tried rear riser con-
trol but do not recommend it because of the performance reduction
due to profile distortion .

Turning flight

The IOTA 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 When starting a turn be
careful how you apply the steering brake – just the right amount; not
too much . Active weight shift effectively assists steering . Angle of bank
can always be increased, stabilised or reduced by brake line load .
The I OTA 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 correspond-
ing 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 .
A harness specifically designed to match the flying characteristics of
the I OTA helps you to initialise and stabilise turns of this type, which
should be as even as possible . See also section «Suitable harnesses» .
Caution: To keep good manoeuvrability make sure to fly your
I OTA with enough airspeed while turning in thermals – not too
much outside brake .
Tip: If a brake line breaks you can steer the I OTA using the C
risers .

Accelerated flight

The I OTA 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
I OTA's high degree of structural stability allows it to be flown in normal-
ly 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 «Speed sys-
tem with SPI» .
