Even though the U-Turn BLACKOUT PLUS has a very high aerodynamic stability it is possible
that the glider gets into an extreme flight situation due to pilot errors or turbulent air. The best
method to stay calm and react correctly is to take part in a flight safety course. The pilot will
learn to manage extreme flight situation under professional supervision. Extreme flight ma-
noeuvres may only be executed in calm air and in sufficient height under professional supervi-
sion (e.g. safety training). Once again we mention that a rescue system is required by the law.
The following extreme flight figures and flight manoeuvres can either be caused intentionally,
through turbulences or through pilot errors. Every pilot can get into these flight situations!
All mentioned extreme flight figures and manoeuvres are dangerous if performed without the
appropriate knowledge, enough altitude or necessary introduction. A wrong execution of these
described figures and manoeuvres may have fatal consequences!
Spiral Dive
Like a normal turn, initiating the spiral dive is very easy with the U-Turn BLACKOUT PLUS.
The spiral dive leads to very good sink rates (up to 15-20 m/sec). To safely use the spiral dive
when necessary it should be practised in calm conditions. You move down vertically within the
airmass. Do not underestimate the G-forces that act upon the pilot when diving down in an ef-
ficient spiral.
The glider has a strong nose-dive when the bank increases during the spiral dive. The behav-
iour is very dynamic and should be piloted through lessening the brake-line-pull on the inside
of the turn resp. accordingly with the outside brake and should only be practised under profes-
sional supervision.
ATTEnTIOn:
If the initiation is too fast there is a danger of a spin, in this
case release the brakes and try a smoother initiation.
Wingover
The pilot has to perform right and left turns with increasing bank until the desired angle is
reached. Collapsing wingtips are prevented by gently applying brake pressure in the up- and/
or down-swing of the wingover. Normally there is no danger of collapsing wing tips with the U-
Turn BLACKOUT PLUS except for when there is a very high bank. With shifting the body weight
while applying the brake it is possible to fly the highest possible wingovers.
Full Frontal
A negative AoA caused by turbulences of the simultaneous pull-down of the A-risers by the
pilot, results in a frontal collapse of the leading edge. The U-Turn BLACKOUT PLUS comes out
of a frontstall by itself very quickly. Smooth and symmetric applying of the brake positively influ-
ences the re-opening of the canopy.
