DAVINCI GLIDERS / JAZZ

12.2 Spiral dive
When you hold one sided brake down for a long time, the
glider goes into a fast sharp turn and loses a lot of height.
We recommend you don’t to get into the sink rate
over 10m/s.
The sink rate could be more than 15 m/sec. To get out of the
spiral dive you must release the inner brake. Mind that JAZZ
may take one more turn after releasing the brake. While spi-
ral diving, the pilot experiences considerable overload up to
3 – 4g, so you can lose orientation.
We recommend to land with trimmers to the normal slow position.When you are 1-2m over
the ground, you should pull the brakes smoothly for minimize vertical speed.
Don’t hit the ground by your overtake the glider.
12 Descent Techniques
13. Landing
12.1 Big ears
Sink rate can be decreased in a controlled way by folding
both wing tips. While holding the brakes you should sym-
metrically pull the outermost A-risers
In order to return to the normal flight, you should release
the A-risers and pull the brake short times until wing tips
regain pressure.
Spiraling is not permitted with big ears, because of the in-
creased load on the remaining lines so that they can be
physically deformed.
