Emergency Controls - Nervures FAIAL Manual

These emergency manoeuvres should only be used when necessary. After a
while they weaken the lines, the ribs and the attachment points.
Attention is drawn to the risk involved when spiralling with a lot of big ears
pulled on. This can increase the load considerably on the front lines to the cen-
tre of the wing and weaken them prematurely, therefore only use this tech-
nique when really necessary and have the strength tested subsequently in our
workshop.
TURNING AND AVOIDING ACTION
The most efficient turns are obtained by weight shifting towards the in-
side of the turn together with action on the control. Once in the turn the adjust-
ment is easily managed using the outside control.
In thermal flight, the turns are corrected mainly by weight-shift:
- to the outside: to flatten the turn and improve sink rate
- to the inside: to bank and accelerate the turn.
An avoiding action is taken by progressively applying the control on the inside
of the turn.
In case of problem with the main controls, the wing can be controlled by
light pressure on the Ds. Take care not to pull too much, as there is a risk of
asymmetric stall. The manoeuvrability will be greatly reduced compared to us-
ing the main controls .
THE WING IN CASE OF STRONG WIND
Approach and landing are performed hands up, as the improved glide
and stability of our wings make them more sensitive to wind gradient.
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 "D" risers to pull down the wing
symmetrically.
Flying in strong turbulence should be avoided. Study the books on aer-
ology to learn to predict turbulent conditions (strong winds, turbulence due to
obstacles, wake turbulence, rotors, lee-side thermals, foehn effect, over devel-
oped clouds, etc...).
If however you do get caught in turbulence, pulling ears with a bit of speed bar
is a good method to quickly reach a landing zone :
. the pendular effect will be damped
. the angle of incidence will be increased and the risk of collapses will
be reduced
