The CAYENNE4 is an EN/LTF C wing and requires very good extreme flight pilot skills.
Your skywalk CAYENNE4 has a very stable canopy, but the possibility of collapse can-
not be eliminated in strong turbulence. You can minimize the one-sided turning of the
collapsed wing by braking the open wing half. With severe collapses, you have to brake
carefully in order to avoid a full stall. if the wing still does not open even with counter
steering, you can accelerate the opening process by pumping the brake on the tucked
side.

SyMMetric cOllapSe (frOnt cOllapSe)
Following a spontaneous or deliberate front collapse the airflow will break away from
the wing, which will pitch back, followed by the pilot. Wait, without applying any brake,
until the wing is overhead again, give it time to start flying, and then you can stabilise it
using the brakes. Following a large collapse, the wing tips may not fully fill when reopen-
ing. Reopening should not be forced with excessive control responses, because of the
risk of a total airflow breakdown.
cravat/line Over:
Maintain the direction as much as possible in an asymmetric collapse by immediate
dosed counter braking and raise the ram pressure by pumping on the closed side.
Steer the open side with care, in order to avoid a stall. Without reaction from the pilot,
a cravat will result in a spiral dive.
there are different possibilities of getting out of the situation:
> Pumping the folded side
> Pull the stabilo (tip) lines
> if neither works, you can exit the cravat by performing a full stall. This maneuver-
should only be attempted by experienced pilots with extreme flight experience and
with adequate altitude.
