Ground Effect; Free Flying Training - Carson Agusta Westland Grand Manual De Instrucciones

Hover flight
Hover flight means maintaining the helicopter in a stable position
in the air. Hover flight is only possible with a helicopter and must be
thoroughly practiced as a fundamental flight formation.
Acquaint yourself with the control functions of your remote control
transmitter so that this procedure gets you're your "flesh and blood".
• Then set the helicopter about 2 m in front of you on the ground,
GB
with the tail facing you.
• Leave the helicopter on the ground and first deliberately move it
slightly sidewise, forwards and backwards.
• When you have mastered control on the ground, give somewhat
more lift and permit it to hover above the ground, without
allowing the tip of the fuselage to turn or the helicopter to drift
away.
• The best procedure is to mark a position on the ground from which
you start the model. Attempt to hold the helicopter above this
position and also to land again on this position.
h. Ground Effect
ATTENTION!
Up to a height of about 30 cm, the model is
in the area of influence of the air turbulence
caused by its own rotors.
On one hand, this "ground effect" facilitates the lift off of the
helicopter since the air pressed downwards by the rotors of the
helicopter helps lift the aircraft from the ground.
But in the immediate area this effect is reversed, since the air flowing
away laterally from the helicopter creates an underpressure and the
model is actually sucked back down towards the ground. This can lead
to an ungentle landing.
i. Free Flying Training
The helicopter is no longer in the area of influence of the air
turbulence from its own rotors as of a flying height of about 2 m and
the flight situation is more stable.
If you have mastered hover flight, begin with
simple flying formations:
• Train your command of the model, allow it to ascend and descend,
hover and move forwards and backward in the air as well as
execute turns.

• When you feel secure, stand laterally to the model and practice
control from this angle of view or
• Allow the model to fly toward you and control it in the opposite
direction.
• Avoid jerky load variation. since otherwise the upper and lower
rotor could touch and cause the model to crash.

• Do not move the control lever too jerkily, because otherwise
especially the touchdown can be very hard. Develop a feeling for
the controls by repeatedly lifting off, floating and landing again.
• If you notice irregularities in the control or an imbalance in the
rotor, land
immediately
and
correct the necessary
settings.
• Increase the flying
height gradually by
degrees.
For this reason the
flight behaviour of the
model at low heights
is rather unstable. If
the restless flight
behaviour causes
difficulties for you,
increase the flying
height by degrees.
• Always fly the model in front of you or allow it to circle above you.
If you allow the model to fly behind your back, you could lose your
orientation and thereby the control over the helicopter.
Never attempt to catch the model in mid flight!
