Dudek VOX-25S, User Manual

Page: 16 / 36

FRONT STALL
If the pilot pulls both A-risers a front-stall is induced: the entire leading edge
tucks and the canopy generally forms a frontal horseshoe.
THE SINK RATE FROM THIS MANOEUVRE CAN BE VERY HIGH.
ENSURE YOU HAVE ENOUGH HEIGHT. THE VOX USUALLY SELF
RECOVERS FROM A FRONTAL STALL AFTER RELEASING THE A
RISERS. TO HELP THE RECOVERY, BOTH BRAKES SHOULD BE
MODERATELY APPLIED.
LINE OVER
If for any reason, lines are tangled or looped around the canopy during flight,
the following action should be taken:
$
Maintain straight flight by gently and feel fully correcting for direction
using the weight shift and brakes!
$
Check the situation carefully and once the line(s) looped around the
canopy, is/are identified pull it/them gently to untangle.
$
Pumping of the brakes in a line over doesn't always work. If a very
large unrecoverable collapse and line over occurs, it may be possible,
to clear the problem by entry and safe recovery from a full stall. This
should only be carried out if sufficient altitude is available. If insufficient
height is available (300m/1000ft), or if in any doubt, the pilot should
strongly consider reserve deployment.
DEEP STALL
The Dudek VOX generally does not remain in deep stall, and is self
recovering, when releasing any brake or riser input used to enter it.
In case the recovery from a B-stall was not dynamic enough and the canopy
remains in a deep stall, it is sufficient to gently pull down both A-risers to
reduce the angle of attack and re-attach airflow to the canopy.
EMERGENCY STEERING
In case it is impossible to control the Dudek VOX with the brake lines the
outer C-lines, C-risers (slightly) or the stabiliser lines may be used to steer
and land the canopy.
