We will begin
this module by
explaining the
basic concept of
the “Fly By Wire“
system.
FLIGHT CONTROLS MENU
System presentation 3/42
This has the
advantage of saving
weight on the
aircraft,
However, there
are, even greater
advantages as the
video clip will
demonstrate.
In conventional
aircraft, the
movement of the
control column is
transferred along
cables and pulleys,
until it reaches the
control surface to
be moved.
In the A320
family however, the
cables and pulleys
have been replaced
by electrical wires.

The electrical signals created by sidestick
movement travel through flight control computers
before being passed to the surface hydraulic
actuators, also named servo controls.
These computers analyze the signal to check that
it is a safe command and ensure the optimum flight
control surface deflection for the demand.

This has advantages over conventional
systems. It :
• makes the aircraft extremely stable,
• enhances safety,
• reduces the workload of the pilot.
Let’s now look at the flight control
surfaces themselves.

The green rudder symbol is used as an index to display
the movements of the rudder on a white scale.
The rudder trim is indicated by a small blue line below
the scale.

Note that the rudder and the pedal
deflections are limited as a function of speed
via a rudder travel limiter.
