In case of failure of a spoiler servo control, the
opposite surface is retracted.
ELECTRICAL FAILURE
In case of total electrical loss, induced roll is
obtained by using the rudder pedals which have a
mechanical control.

YAW CONTROL NORMAL D/O
GENERAL
The yaw control is performed by the rudder, with a
maximum deflection of 25° (30° for the A319), and is
controlled by deflection of the pedals.
The rudder is operated by three moving body
servocontrols with a common mechanical input. This
mechanical input can receive commands from:
- rudder pedal input (mechanical control)
- rudder trim actuator (electrical control)
- yaw damper input (electrical control)
RUDDER PEDALS
The two pairs of rudder pedals are connected together.
They are linked by a cable loop to the mechanical
summer unit which in turn is connected to the hydraulic
rudder actuators via a differential unit.
Mechanical rudder control is always available from the
rudder pedals.
The pedal position signals are sent to the Elevator
Aileron Computers (ELACs) by the transducer (XDCR)
unit.
ELEVATOR AILERON COMPUTER
In manual flight, the ELACs transmit the yaw damping,
turn coordination and rudder trim commands to the
Flight Augmentation Computers (FACs).
The yaw damping and the turn coordination orders do
not move the rudder pedals (no feedback).
FLIGHT AUGMENTATION COMPUTER
The two FACs control the yaw damper servo controls,
the rudder trim and the rudder travel limitation unit.
FAC 1 has priority. FAC 2 is in hot stand-by.
FLIGHT MANAGEMENT AND GUIDANCE COMPUTER
When the autopilot is engaged, the Flight Management
and Guidance Computers (FMGCs) send commands to the
FACs for rudder trimming, yaw control and yaw damping
function.
RUDDER
The rudder is powered by three hydraulic actuators
operating in parallel.
RUDDER TRIM
The rudder trim is achieved by two electric motors,
each controlled by its associated FAC.
In manual flight:
- The pilot can apply rudder trim at 1°/sec from
the RUD TRIM rotary switch.
In automatic flight:
- The asymmetry compensation function is
available in case of lateral asymmetry.
- The yaw automatic trim is active for lateral
asymmetry and engine failure compensation at
5°/sec.
Trimming causes rudder pedal movement.

RUDDER LIMITATION
Rudder deflection limiting is achieved by a variable
stop unit driven by two electric motors. Each motor
is controlled by its associated FAC.
The rudder deflection becomes limited as speed is
increased.
YAW DAMPING
The two yaw dampers servo controls are connected to
