Even though the U-Turn ETERNITY has a very high aerodynamic stability it is possible that the
glider gets into an extreme flight stituation 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 situatuion under professional supervision. Extreme flight maneuvers
may only be executed in calm air and in sufficient hight under professional supervision (e.g.
safety training). Once again we mention that a rescue system is required by the law. The follow-
ing extreme flight figures and flight maneuvers can eigher be caused intentionally, through tur-
bulences or through pilot errors. Every pilot can get into these flight situations! All mentioned
extreme flight figures and maneuvers are dangerous if performed without the appropriate
knowledge, enough altitude or necessary introduction. A wrong execution of these described
figures and maneuvers may have fatal consequences!
Spiral Dive
Like a normal turn, initiating the spiral dive is very easy with the U-Turn ETERNITY. The spiral
dive leads to very good sink rates (up to 15-20 m/sec). To safely use the spiral dive when neces-
sary it should be practised in calm conditions. You move down vertically within the airmass. Do
not unterestimate the G-forces that act upon the pilot when diving down in an efficient 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 wintips 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 ETERNITY except for when there is a very high bank. With shifting the bodyweight 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 ETERNITY comes out of a
frontstall by itself very quickly. Smooth and symmetric applying of the brake positively influenc-
es the re-opening of the canopy.
