Ozone Swift Six - Cravats; Deep Stall; Parachutal Stall

Cravats
If the tip of your wing gets stuck in the lines, this is called a ‘cravat’. This can make your glider go into a
spiral, which is difcult to control. The rst solution to get out of this situation is to stabilise the glider into
normal ight, i.e get control of your direction and then use strong deep pumps of the brake on the cravated
side. When doing so it is important to lean away from the cravat otherwise you risk spinning or deepening
the spiral. The aim is to empty the air out of the wing tip, but without spinning. Correctly done, this action
will clear the cravat quickly and is the most efcient and effective method. You can also try pulling on the
stabilo line to free small stubborn wing tip cravats. Whichever method you use, be careful with any brake
inputs as you may stall the opposite wing.
If it is a very large cravat and the above options have not worked then a full stall is the next option. Only
attempt this if you have enough altitude and you know what you are doing. Remember if the rotation is
accelerating and you are unable to control it, throw your reserve parachute immediately whilst you still
have enough altitude.
Deep Stall / Parachutal Stall
It is possible for gliders to enter a state of parachutal stall. This can be caused by several situations
including; a very slow release from a B-line stall; ying the glider when wet; or after a front/symmetric
deation. The glider often looks as though it has recovered properly but carries on descending vertically
without full forward motion. This situation is called ‘deep stall’ or ‘parachutal stall’.
It is unlikely to happen on any Ozone glider, but should it do so your rst reaction should be to fully raise
both hands. This normally allows the glider to return to normal ight but If nothing happens after a few
seconds, reach up and push the A-risers forwards or apply the speed bar to encourage the wing to regain
normal ight. Ensure the glider has returned to normal ight (check your airspeed) before you use the
brakes again.
Do not y in rain, doing so signicantly increases the likelihood of parachutal stalls occurring. To reduce
the chance of stalling in rain avoid using deep brake movements or Big Ears. Find a safe area to land and
using the speed bar, maintain a good airspeed at all times.
WARNING
Uncoordinated
wingovers can lead
to large asymmetric
collapses and cravats,
therefore they should
never be executed
near the ground.
IMPORTANT
A bad preparation
on launch, aerobatic
ying, ying a wing of
too high a level or in
conditions too strong
for your ability, are
the main causes of
cravats.
IMPORTANT
Only a few cms of
input from your
brakes can maintain
your wing in the stall.
Always release your
wraps if you have
taken them!
