5. LDG FLAP 3 : The flap 3 landing configuration
is selected, no flap alert will be
generated when landing in this
configuration. If you choose to land with Flap
3 configuration (refer to the PERF APPR
page for more information), this switch must
be pressed to avoid having a flap alert in
short final.

FLIGHT CONTROLS
Sidesticks & Rudder Pedals
There is not much to say about flight controls
as they were described in detail in the Fly-by-
Wire section. The only thing to keep in mind is
that a strong action on the stick or on the
rudder pedals disconnects the autopilot. As
this is not the standard procedure, it triggers
an alarm that can be stopped by pressing the
A/P disconnection button.
Flight Control Computers
Seven computers are in charge of the Fly-by-
Wire system: 2 Elevator and Aileron Computers
(ELAC), 2 Spoiler and Elevator Computers (SEC)
and 2 Flight Augmentation Computers (FAC).
All these computers can be turned off using
the switches located in the 2 FLT CTL sections
of the overhead.
These switches are supposed to be used in
case of failure, to reset the flight control
computers by turning them off and back on.
They are not designed to turn these computers
off.
The FACs are in charge of the flight envelope
protection, the auto-trim system and the autocoordination.
If they are turned off, amber
crosses appear on the PFD to indicate there is
no flight envelope protection: no bank angle
limit and no pitch angle limit.
Auto-coordination in Flight Simulator :
When you load this aircraft in Flight Simulator, the
FS auto-coordination is turned on according to the
FAC status. When the aircraft is unloaded from FS,
the previous auto-coordination status is restored.
Speed Brakes & Ground Spoilers
Speed brakes and ground spoilers are
different, even if they are controlled through
the same handle and use the same aircraft
parts. The speed brakes can be deployed in
flight, they use 4 of the 5 moving panels on the
top of the wings and their movement is limited
to approximately 50% of the maximum
deployment. The role of the speed brakes is to
reduce the lift and increase the drag to
decelerate the aircraft in flight. If they are
deployed, a green message 'SPPED BRK' is
displayed on the E/WD.
The ground spoilers can be deployed on the
ground only. They are used to reduce the
aircraft speed and to break the lift for optimal
break efficiency. When they are activated, all
the 5 panels deploy at their maximum angle.
The ground spoilers can be armed to deploy
automatically during takeoff in case of a
rejected takeoff or during approach to deploy
when the aircraft touches the ground upon

landing. When they are armed, a green
message ‘GND SPOILERS ARMED’ is
displayed on the E/WD. When the ground
spoilers have automatically deployed, the
action of disarming them will make them
retract.
The upper and lower parts of the handle can
be clicked to move the handle up and down.
Moving the handle higher than the RET
position (retracted) arms the ground spoilers.
Moving the handle down deploys the speed
brakes progressively.
Speed Brake/Ground Spoiler control in Flight
Simulator :
The standard FS keys can be used to arm/disarm the
ground spoilers and extend/retract the speed brakes. By
default, the ‘/’ key is used to extend/retract the speed
brakes and Shift-/ is used to arm/disarm the spoilers.
Flaps
The flaps have specificity on this aircraft: the
flap handle has 4 positions while the flaps and
slats can have 6 positions, as shown in the
following table :
Flap/Handle Flap/Slat Flap Slat Usage Max Speed

The table also shows how the different
flap/slat configurations are to be used, and the
maximum airspeed for each configuration.
