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.

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.

The pressure builds up symmetrically on the left and right sides
and reaches about 2600 PSI with full pedal deflection.

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.

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.

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
position, NW STRG DISC memo is displayed in green
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.
