Let’s assume that the chocks are in place in order to verify the
brakes and brake accumulator pressure.
The accumulator brake pressure is checked before setting the
brakes.
The pressure indication should be in the green area. This
indicates that the accumulator can hold the parking brake
pressure for 12 hours.
If the pressure indication is not in the green arc, use the yellow
hydraulic electrical pump to recharge the brake accumulator.
LANDING GEAR MENU
Normal Operation 4/83
We continue the test by pressing on the top of the rudder pedals to
apply maximum brake pressure.
We will check that the two needles indicate about 2600 PSI. This
check verifies that the brakes work correctly from the accumulator.

As we will be checking the brake wear indicators during the
walk around, we must set the PARK BRK ON.

On the E/WD memo section PARK BRK in green
indicates that the PARK BRK handle is in the ON
position.
LANDING GEAR MENU Normal Operation 12/83
Notice that the pressure to the main brakes is indicated
for each main landing gear. This is yellow hydraulic
pressure. The PARK BRK uses the alternate braking
system which is powered by yellow hydraulic pressure.
LANDING GEAR MENU
Normal Operation 13/83
On the nose wheel we check the following:
- the gear structure and download springs
- the hydraulic lines
- the electrical wires
- the chocks, wheels and tires.
LANDING GEAR MENU Normal Operation 14/83
On the main gear we check the following:
- the gear structure and download springs
- the wheel well for general condition
- the chocks, wheels and tires
- the hydraulic lines
- the electrical wires.
LANDING GEAR MENU Normal Operation 15/83

The brake wear indicators indicate the state of the
carbon disks.
Note: as previously mentioned, the parking brake must
be on for an accurate brake wear check.
LANDING GEAR MENU
Normal Operation 17/83
We are back in the cockpit for the cockpit
preparation.
We verify that the three gear pins and covers are on
board and stowed. We also check that the Gravity Gear
Extension lever is stowed.

During pushback, the nose wheel steering
selector, located on the nose wheel, is in the towing

on the E/WD. With this indication, nose wheel
steering is not possible from the cockpit.

The push back is completed.
Both engines are running and we will check the brakes in order to
verify that green pressure has taken over and that yellow pressure is
at zero on the brake pressure triple indicator.
To initiate the test, we first press the top of the rudder pedals and
we remove the PARKING BRK.

Notice the two green triangles for each gear. They indicate that the
gear is down and locked. There are two triangles because there are
two computers which provide the information for these indications.
These computers, called Landing Gear Control and Interface Unit

The following indications show that the AUTO
BRK is armed:
- ON in the selected pb,
- A message in green on the ECAM wheel page
- and AUTO BRK MAX changes from blue to green
on the take off configuration message.
LANDING GEAR MENU
Normal Operation 41/83
During taxi, either steering handwheel can be used to
control the direction of the aircraft.
The steering handwheel provides 75 degrees of nose
wheel deflection left or right. Signals from each handwheel
are summed up: if two handwheels are moved in the same
direction the nose wheel deflection will be equivalent to the
sum of the handwheel commands.
LANDING GEAR MENU Normal Operation 42/83
LANDING GEAR MENU
Normal Operation 43/83
While you are taxiing the aircraft for take off, you will check
the flight controls.
To check the rudder, you must press the rudder pedal
disconnect switch.
This button disconnects the nose wheel steering from the
rudder so that you can check full deflection of the rudder
pedals versus the indications on the ECAM.
You will see and do this in the normal operation module of
the flight controls.
LANDING GEAR MENU
Normal Operation 44/83
During take off, the aircraft direction is controlled exclusively
using the rudder pedals.
The rudder pedals provide up to 6 degrees of right and left
deflection at low speed.
As the speed increases, this deflection angle decreases
progressively until 130 kt, when directional control is 0 percent
nosewheel and 100 percent rudder.

indicates that there is a discrepancy between the
landing gear and lever position.
Watch the ECAM and the landing gear lights. We
will point out the changes as they occur.

The DECEL light illuminates green when the
aircraft deceleration is at least 80%of the selected rate.
LANDING GEAR MENU
Normal Operation 73/83
AUTO BRK action depends on the rate selected:
- LO: braking after approximately 4 seconds,
- MED: braking after approximately 2 seconds and
higher deceleration than in LO,
- MAX: immediate braking, with max deceleration
rate. This mode is only used for take off.
LANDING GEAR Normal Operation 74/83
On the ECAM WHEEL page, watch the green
dashes. They appear during braking indicating that
the A/SKID is active.
MENU
LANDING GEAR Normal Operation 75/83
The AUTO BRK can be deselected either using the
corresponding pb on the AUTO BRK panel, or by
applying sufficient force to one brake pedal in LO and
MED, and to both brake pedals in MAX.
MENU
LANDING GEAR Normal Operation 76/83
On the ECAM WHEEL page check the brake
temperature for significant differences and high
temperatures.
A maintenance action is required when the difference
between two brakes of the same gear is greater than 150
degrees or when the mean temperature of one gear
differs by more than 200 degrees with another gear.
MENU
