Advance acoustic SIGMA 11, Руководство пользователя, Страница: 20 / 38

Fullstall
Although the SIGMA 11 responds early to brake input it has very long
brake travel, and very high brake load at the stall point . This means a
large safety margin for the pilot .
Entry into a fullstall is achieved by progressively and symmetrically pul-
ling down both brake lines . Forward speed reduces . Airflow and wind
noise reduce . After reaching minimum speed the paraglider first go-
es into a brief phase of parachutal stall . Then further brake will cau-
se complete airflow breakaway, and the wing will fall back in fullstall .
The SIGMA 11 has a strong desire to fly again, but is easy to hold in the
stall . A half wrap of the brakes is recommended to fly fullstalls .
To recover, the canopy has to be pre-inflated . To do this the brakes
should, at first, be released slowly and symmetrically, and only fully re-
leased when pre-inflation is complete . The SIGMA 11 then flies away
relatively cleanly, without shooting forward too much .
Tip: As a basic principle you should immediately and fully re-
lease both brakes in all out-of-control situations, then be pre-
pared to control the resulting surge carefully .
Deep stall
Stable parachutal stall cannot be established, whether attempted by
brake or B-stall .
In rain, or if the canopy is wet, the SIGMA 11 like all paragliders, is mo-
re vulnerable to parachutal stall . If the wet glider were to go into pa-
rachutal stall you should recover only by accelerating using the speed-
bar . See also section “Flying with a wet paraglider” .
