Advance acoustic EPSILON 7 Getting Started page 10

Descent aids
For coming down quickly and efficiently the
ADVANCE test team primarily recommend
that you use big ears (with or without speed-
bar), so as to fly away from danger vertically
as well as horizontally.
The EPSILON 7 has split A-risers, which make
big ears easier. To apply, pull both outer,
red-marked A-lines briskly downwards at the
same time. To reopen, release the A-lines;
the folded ears will open by themselves,
thanks to the EPSILON 7's high internal
pressure. Sink speed can be increased by
using the speed system while big ears are
applied.
Another descending aid is the spiral dive.
When you are in the spiral keep your weight
neutral. The EPSILON 7 comes out of a spi-
ral by itself with a neutral sitting position. At
high sink rates of more than 14 m/s a steep
spiral can become stable if weight is applied
