DAVINCI GLIDERS OPERA, Руководство пользователя

Страница: 11 / 24

It is possible for gliders to enter a state of deep stall. This can
be caused by several situations including; flying the glider
when wet; very old glider; or after a front/symmetric deflation.
When you meet this situation you should fully raise up the
both brakes and push the A-risers forwards or use the speed
bar symmetrically to regain a normal flight.
The cravat can occur when the tip of the wing comes into the
glider line due to the collapsed situation. When it’s happened,
the first action is to make the glider could not be lost the
course where you go. For this, you need to do weight shift
and pull the brake to the other side of cravat wing until the
glider is stable and go straight.
Once you can control your wing to the course, you need to
pull the brake lines at the cravated side strongly and release
it. You need to repeat this pumping action several times.
If you lost the timing for keeping the course, the glider can
be entered spiral dive.
When you pull the one of the brake too much, a
asymmetrical stall may occur.
If the small cravat can be solved by pulling the stable line.
The full stall maneuver is the last step of the solution to solve
the cravat but you have to know about that skill very well
before try it.
You have to keep in mind that if the rotation is accelerating
and you can not manage the glider, you should open the
reserve parachute system immediately before the low altitude.
Cravat(wing Tangle) Deep stall
Asymmetrical stall
It can take place when you pull one of the brake too hard, or
while spiraling at a small speed in turbulence you increase
the angle of attack. Rotation in the asymmetrical stall is
called negative spiral. This is one of the most dangerous
flying situations. In order to get out of asymmetrical stall, just
release the brakes. There may follow side thrust forward with
a following wing collapse.
Traditional B-line stalls are not possible with 2 liners glider
like the OPERA.
If you pull the B lines, it will be occurred a full stall.
We strongly do not recommend this maneuver for OPERA.
