LANDING GEAR MENU Normal Operation 1/83 LANDING GEAR MENU Normal Operation 2/83 LANDING GEAR MENU Normal Operation 3/83 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. IInniittiiaattee tthhee tteesstt..

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 LANDING GEAR MENU Normal Operation 16/83 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.

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.

MENU LANDING GEAR Normal Operation 52/83 As soon as the landing gear lever is moved to the up position, the message L/G CTL appears. This 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. MENU LANDING GEAR Normal Operation 53/83 The landing gear doors deflect downward and change to amber to indicate that they are open. At the same time, on the main gear, the braking system automatically brakes the wheels. As the doors close, you will hear in the cockpit the sound of the brake band braking the nose wheels. MENU LANDING GEAR Normal Operation 54/83 Then the landing gear retracts. There are two sets of indications which inform the pilot that the landing gear is no longer locked: - red unlock is illuminated in the position indicator lights - and the landing gear indicators become red on the ECAM wheel page.

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.
