B-Line Stall; Big-Ears - Team 5 GREEN Betriebsanleitung

absolutely prohibited. Since there are strong forces acting on the pilot during extreme spiral rotations
and its initiation presents problems in very turbulent conditions, we also recommend - owing to the
GREEN's appropriate design - to use the B-Stall with the GREEN. The spiral dive (sinking about 8-15
m/s) still remains the most effective method for descent and should therefore be practiced. A B-stall
(sinking about 6-8 m/s) is not appropriate for every type of emergency situation.
B-LINE-STALL
Out of unaccelerated normal flight, it is best to grasp the B-lines
on both sides above the line links and pull them down. There is no
need to release the toggles while B-stalling. The first 10 cm require
a relatively high power input. Then a full stall will occur, the canopy
bunches up in the direction of the profile and by pulling down fur-
ther ( another 10 cm) you will achieve a high sink rate while keeping a completely stable "flight"
position. Pulling the B-lines even further down will not enhance the sink rate but lead to a more
unstable flight position and turning away of the canopy.
By releasing the risers the canopy will accelerate immediately without strong oscillation effects. A
rapid release is recommended. The GREEN does not show any tendency to remain in stalled flight.
Should it not catch up right away, a simultaneous push on the A-risers will remedy this condition.
BIG EARS
By pulling on the rear (outer) A-riser and holding down the outer
A-lines the wing tips of the GREEN can be folded in. This method
drastically deteriorates the glide angle but without being an effec-
tive method for descending. The use of big-ears is only sensible for
getting away horizontally out of moderate thermals without gaining
more altitude (such as at cloud base or at risk of being blown back-
wards into lee). The horizontal speed only increases very little, the flight path speed increases signifi-
cantly. The effectiveness of this technique can be increased by using the speed system at the same
time. To reinflate it is simply necessary to release the line - only in exceptional cases is it necessary to
help the reinflation with brief, deep pumps of the brake on the deflated side.
Caution: In this configuration no additional spiral dive may be flown since only a part of the line attach-
ments can take up the increased loading caused by the turn and the canopy would be overloaded!
