TURNING AND AVOIDING ACTION
The most efficient turns are obtained by a transfer of weight in the
harness towards the inside of the turn accompanied by action on the control.
Once in the turn the adjustment is easily managed using the outside control.
In thermal flight, the turns are corrected mainly from the harness :
- tipping weight to the outside: to flatten the turn and improve sink rate
- tipping weight to the inside: to incline and accelerate the turn.
An avoiding action is taken by smoothly applying the control on the inside of
the turn.
THE WING IN CASE OF STRONG WIND
We advise the pilot to get into the habit of standing up during the
approach sooner as more gusty are the flying conditions. His position will be
better in case of hard landing.
We do not advise to end the approach in a "big ears" configuration which
could be difficult to recover from in case of deep stall because of gradient
situation.
At the moment of landing in a strong wind, as soon as the wing is stable, the
pilot should release the brakes and grab the "C" risers to pull down the wing
symmetrically.
Flying in turbulence should be avoided at all cost. Study the books on
aerology to learn to predict turbulent conditions (strong winds, turbulence due
to obstacles, wake turbulence, rotors, leeside thermals, foehn effect, over
developed clouds, etc...).
If however you do get caught in turbulence, there is only one thing to do:
reduce your speed (30 to 50% brakes).
. incidence is increased (less risk of the leading edge going into
negative incidence )
. the pendular effect will be damped in the transition,
. the wing, in the case of a deflation, will reinflate immediately
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.
