PARACHUTAL PHASE (DEEP STALL)
Even though it has never happened during the tests, should the
phenomenon arise, to put the wing back into normal flight one should engage a
moderate turn and then control the surge which follows by applying adequate
braking.
If this phenomenon does occur it is a sign of ageing and requires a wing
inspection. In the case of a deep stall close to the ground, it is better to land
with the hands high than to try to get out of the deep stall.
CLOSURES
The reopening, on this model, is very generally spontaneous and
immediate, especially if the pilot takes care and flies with some braking when
the conditions are likely to cause closures.
Even though the likelihood of this has not been shown during the tests, it
cannot be excluded that after a massive closure which causes a turn, if nothing
is done, it could degenerate into auto-rotation .
To correct for this the pilot should transfer his weight to the inflated side and
brake on the outside of the turn. Once the rotation has been stopped, if the
wing has not already reopened, pull on both controls briefly and simultaneously
to open it, without slowing the wing excessively to avoid a stall.
A DEFLATION, EVEN PARTIAL, CAN NEVER BE CONSIDERED
ACCEPTABLE AND THE FLIGHT SHOULD CAREFULLY BE SHORTENED.
RADICAL MANOEUVRES
Radical manoeuvres should be avoided. They have been done during
the numerous test flights but are not within the normal flying limits of a
paraglider.
- wingovers with more roll than 45° either side of the vertical,
- slowing and then releasing the controls producing pitching movement
Greater than 30° either side of the vertical,
- Stalling manoeuvres,
- sudden turns at very low speed, susceptible of degenerating into flat
spin or asymmetric stalls,
- closing manoeuvres using the risers.
