Rapid Descents - Advance acoustic ALPHA 7 Manual

Symmetric collapse ( frontstall )
After a spontaneous or a deliberate front collapse using all A-risers the
airflow breaks away from the profile and the canopy will pitch back .
The pilot will soon swing back underneath . Wait, without applying
brake, until the wing is again above you and returns to normal flight .
After a big collapse reopening may be delayed, but do not forceably
encourage reopening by the use of excessive brake, because of the
risk of a fullstall .

Rapid descents

For quick and efficient ways of getting down the ADVANCE test team
recommend big ears ( with or without speed bar ) or the spiral dive – the
choice depends on the situation .
Tip: Fast descents should be practised now and then in quiet
conditions – so they won't become emergencies when you need
them .
Symmetrical collapsing of the wingtips ( big ears )
The ALPHA 7 has split A-risers, which make applying big ears easy .
The outer, narrower A-risers with a red covered line are separated spe-
cially for this . To do this manoeuvre pull both of these narrower, outer
risers . This will fold the wingtips in, and you can hold them there easily .
To reopen release the risers; the ALPHA 7 wingtips then open them-
selves thanks to the high internal wing pressure .
Sink rate can be further increased by using the speedbar when the
ears are folded . Depending on the situation the glider can be steered
using weight shift .
Info: Big ears is also possible using two lines ( per side ) with the
ALPHA 7 . Here it is important that the glider must then be accel-
erated as well, and the trailing edge must not be braked .
Caution: Do not fly spirals or sharp changes of direction with
big ears applied; the increased loading carried by fewer lines can
damage the structure .
Tip: If you want to lose height as quickly as possible and fly
away from a problem area at the same time we recommend the
following: apply big ears and use as much speedbar as condi-
tions allow .
