Caution: The ALPHA 7 was tested in accordance with the latest
certification requirements . In a neutral sitting position, and after
releasing the inside brake, a spiral dive of up to 14 m/s sink rate
recovers by itself . Spirals of higher sink rates can remain in a sta-
ble spiral if weight shift is applied to the inside of the turn . Weight
shift to the outside or pulling outside brake is sufficient to recov-
er from a high speed spiral .
Caution: The ALPHA 7 is certified for harnesses in group
GH ( without rigid cross-bracing ) . Group GX harnesses ( with
cross-bracing ) or those with very low hang points could dras-
tically alter the flying behaviour in the spiral dive . See section
«Suitable harnesses» .
Caution: Do not fly spiral dives or aggressive changes of di-
rection with big ears applied: the raised wing loading carried by
fewer lines can damage the glider .
B-Stall
The whole paraglider structure and its profile shape would be severely
strained by a B-stall . We recommend that you do not carry out B-stalls
on a regular basis . If you do fly a B-stall the recovery requires that the
B-lines are completely released without hesitation, so that normal flight
is resumed within 2 seconds . B-stall is difficult for light pilots because
of the high force required .
