8.3 Flight
In conditions of calm rising air, you can fly with the VG tightened to a degree, which enables a better
rate of climb to be achieved.
However, in general, you should use VG in proportion to the speed at which you wish to fly. The faster
the desired speed, the more you should tension the sail by tightening the VG.
It is usually counter-productive to fly at excessively low speed with the VG fully tightened, because
manoeuvrability is lower when VG is tight. In addition, under these conditions, stalling is faster and more
marked than when the VG is released, and this requires faster reactions on the part of the pilot, and
more altitude in which to return to normal flight.
IMPORTANT: therefore you should never fly close to the ground with the VG fully tightened,
Use the VG according to the aerological conditions: in turbulence, the wing should not be excessively
loose, which would reduce performance, but neither should manoeuvrability be compromised by too
much VG.
8.4 Landing
When flying the Alto, the final flare is easily performed under all conditions and VG configurations. Close
to the ground though, you should not have more than ⅓ VG on in order to ensure a fast response time
for your glider.
When landing in turbulent conditions, it is better to leave the VG off.
After the approach, fly your final leg into the wind at a medium-high speed.
When you are close to the ground slow down smoothly, flying parallel to the ground and gradually
easing up the speedbar.
As soon as you feel that the glider is about to stall, flare! With less wind you should flare harder. If
the wind speed on the ground is greater than 15 km/h, the final stall does not have to be so
energetic. The greater the wind at ground level, the less pronounced your stall should be.
9. Trim
When the glider is assembled, the sail must be placed on the frame in such a way that the tension is
perfectly symmetric.
The sail's tension may be modified by adjusting the fibreglass tip lever tension or the pressure exerted
on the batten tips at the trailing edge.
On all Icaro's wings you can also adjust wingtip sail tension by means of the plate with multiple holes
that permits leading edge tension to be modified.
Unless absolutely necessary, we strongly suggest that you leave the sail tension as when delivered from
the factory.
9.1 Turn tendency
9.1.1 Turn tendency with no VG:
Verify the batten profile using the supplied batten plans.
Check that the sail tension on the left fibreglass tip is the same as on the right fibreglass tip. If they
are different, fix the lever to a different hole in order to restore symmetrical tension.
Check that the tube holding the fibreglass tips (at the end of the leading edge) is not damaged, and
that the tips are held correctly inside it.
Check that the sail tension on the left wingtip is equal to that of the right wingtip. If there is a
difference, fix the sail at a different hole so that tension is properly balanced.
Check that the eccentric Nylon caps, holding the above-mentioned tubes, are symmetrical.
Check that the leading edge and all other tubes are undamaged.
