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have been replaced
by electrical wires.

FLIGHT CONTROLS MENU System presentation 5/42

System presentation 6/42
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.

FLIGHT CONTROLS MENU System presentation 7/42
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.

System presentation 14/42
The movements of both ailerons and both
elevators are symbolized by a green index moving
in front of a white scale.
FLIGHT CONTROLS MENU
System presentation 15/42
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.
FLIGHT CONTROLS MENU System presentation 16/42
High speed position
Note that the rudder and the pedal
deflections are limited as a function of speed
via a rudder travel limiter.
The high speed position is indicated by
small white ticks on the rudder scale.
FLIGHT CONTROLS MENU
System presentation 17/42
The PITCH TRIM position is indicated by THS
deflection in degrees up or down.
Let’s continue with the spoilers.
FLIGHT CONTROLS MENU System presentation 18/42
The spoilers have several
functions:
• Speed brakes use the 3 central
surfaces,
FLIGHT CONTROLS MENU System presentation 19/42
• Roll control uses the four outer
surfaces,
On the video, look at the left spoilers
as they deploy, then at the right ones as
the wings are leveled .

• Ground spoilers use all surfaces.
On the video, watch as all the spoilers deploy
at touchdown.

FLIGHT CONTROLS MENU
System presentation 21/42
On the ECAM F/CTL page, the spoiler extended position
is indicated by small arrows. This is the speed brake case.
All these control surface indications will be explained in
more detail in the normal and abnormal operation modules.
Now, we will look at the flight control computers.

The hydraulic systems which actuate each
control surface are indicated on the ECAM F/CTL
page by the use of G, B and Y.
For example, the rudder is powered by the
Green, Blue and Yellow hydraulic systems.
The ECAM F/CTL page is now complete.

Pilots control pitch and roll through two side
sticks.
FLIGHT CONTROLS MENU
System presentation 29/42
There are associated side stick
priority lights.
Side sticks and priority lights will
be explained in a separate module.
FLIGHT CONTROLS MENU
System presentation 30/42
Pitch trim wheels are located on
the center pedestal.
FLIGHT CONTROLS MENU System presentation 31/42
There are two sets of
conventional rudder pedals.
FLIGHT CONTROLS MENU
System presentation 32/42
A RUD TRIM panel is located on
the pedestal.
FLIGHT CONTROLS MENU
System presentation 33/42
A speed brake lever is located on
the left side of the pedestal.
FLIGHT CONTROLS MENU
System presentation 34/42
In addition, there are two panels, located
on the overhead panel to control the flight
control computers .
Now, we will introduce the lift
augmentation devices.
FLIGHT CONTROLS MENU
System presentation 35/42
There are 5 slats on each
leading edge ...
FLIGHT CONTROLS MENU
System presentation 36/42
and 2 flaps on each trailing
edge.
FLIGHT CONTROLS MENU
System presentation 37/42
The slats and flaps are hydraulically actuated like
all the other surfaces. They are electrically controlled
via two Slat Flap Control Computers (SFCC).
SFCC 1
SFCC 2
FLIGHT CONTROLS MENU
System presentation 38/42
Each SFCC has two channels, one for the flaps
and one for the slats.
Each channel can drive its associated surfaces.

The flap lever, located on the right
side of the pedestal, operates the slats
and flaps.
The flap lever has the following
positions:
0, 1, 2, 3 and FULL.
FLIGHT CONTROLS MENU
System presentation 40/42
The flaps and slats information is shown on the E/WD.
The flap and slat positions are indicated by white dots.
Here, the surfaces are extended to position 1+F.
FLIGHT CONTROLS MENU
System presentation 41/42
This is Flap 0 indication. Notice there is no labeling with
this setting.
FLIGHT CONTROLS MENU System presentation 42/42
The slats and flaps are fitted with
protection functions.
In particular, Surface asymmetry
between left and right wing, Surface
attachment failure, Overspeed or
uncommanded movement are detected.
All these protections will be seen in
detail in the abnormal operation
modules.
