SPIN AND FULL STALL
Practically do not occur. It may happen only as a result of serious mistake or
intentional action. In normal flight braking up to the stall point requires much
force and its proximity cannot be overlooked.
Wing recovers spontaneously in initial phase of stall, otherwise use standard
procedures.
WING OVER
You make a wingover by executing a series of consecutive, alternating turns
with growing bank angle. Too much banking with some flaws in coordination
can evoke pretty dynamic collapse.
CAUTION: Steep turn with bank angle over 60 degrees is a prohibited
aerobatic manoeuvre!
FRONTAL COLLAPSE
Can happen in strong turbulence. Active piloting will usually prevent its
occurrence. Under normal conditions Orca XX reinflates instantly and
spontaneously. Applying some brakes in the right moment will greatly speed
up the recovery.
LINE OVER (CRAVATTE)
Not very likely when flying Orca XX. Use standard action, in case of any
doubts pilot should seriously consider throwing the rescue chute.
DEEP STALL
Under normal conditions does not occur.
If you want to prevent it, stick to a couple of rules:
<
after B-stall, release the risers quick and even. Orca XX does not jump
forward excessively.
<
prior to executing Big Ears you should fully open the trims. It will
increase the sink rate and safety margin, as big ears constitute an
aerodynamic brake with significant loss of speed.
If parachutal stall happens nevertheless, best solution is to push forward A
risers or pull them downward.
EMERGENCY STEERING
In case of malfunction rendering it impossible to control Dudek Orca XX with
brakes, you can safely steer and land using the D-risers (blue) or stabilo lines.
