SINGLE AISLE TECHNICAL TRAINING MANUAL

Trang 6

The single aisle family is equipped with two forward and two aft

passenger doors These are plug-type doors that open upward, outward

and forward parallel to the fuselage The doors can be operated from

the inside or the outside the aircraft Normal operation of the doors

is manual, with hydraulic damping

Each door is equipped with an emergency opening system:

- An escape slide stowed in a container attached to the lower side of

the door,

- A door damping and emergency operation cylinder that assists normal

door operation and acts as an actuator for automatic door opening in

an emergency,

- a slide ARMING/DISARMING lever When the slide-arming lever

is in the ARMED position, the slide is connected to the floor When

the door is opened, the escape slide inflates and deploys automatically

Opening the door from the outside disarms the door and the escape

SYSTEM OVERVIEW (continued)

EMERGENCY EXITS

The A318 and A319 are equipped with two overwing emergency exits

(one on each side)

The A320 is equipped with four overwing emergency exits (two on

each side)

The A321 is equipped with four emergency exit doors (two on each

side) located forward and aft of the wing

On the A318, A319, and A320 aircraft, for emergency evacuation,

the exit can be opened from inside or outside the cabin to activate the

evacuation system Normally these emergency exits are always armed

To open the exit for maintenance, authorized personnel must disarm

it from the inside

The A321 emergency exit door can be opened from inside or outside

These exits must be armed in flight and disarmed on the ground

CARGO DOORS

The cargo compartment doors, installed on the lower right hand side

of the fuselage, give access to the forward and aft cargo compartments

They open outwards and upwards from the fuselage They are

manually locked and unlocked by a locking handle on the door The

forward and aft cargo doors are operated hydraulically using the yellow

system electric pump

In case of electrical failure the door can be opened manually using a

hand pump

The bulk cargo door is installed aft of the aft cargo door on the A320

and A321 The bulk door gives access to the bulk cargo compartment

The door is operated manually and opens into the compartment

COCKPIT DOOR

The cockpit door separates the cockpit from the cabin It is an armored

and bulletproof door designed to prevent a hijacking attempt and to

protect the flight compartment against an intrusion The door is always

locked when closed and the aircraft is powered A Cockpit Door

Locking System (CDLS) controls the electrical release of the door

lock and prevents unauthorized access into the cockpit The door has

a door escape hatch with two pip-pins, which keep the hatch in

position

The components of the cockpit door locking system include:

- Cockpit door panel on the pedestal with toggle switch to control the

cockpit door locking and unlocking,

- Keypad in the cabin for cockpit access authorization,

- Three electrical release strikes,

- Overhead control unit in cockpit with integrated maintenance

annunciators,

- Buzzer on cockpit overhead panel

EMERGENCY COCKPIT DOOR ACCESS

We can get access to the cockpit in case of emergency

1 Enter the four digit code plus "#" on the keypad

- The buzzer in the cockpit comes on continuously,

- The green LED on the keypad flashes

2 If the cockpit toggle switch is not operated within a set time (15

sec - 2 minutes), the control unit unlocks the door for 5 s During this

5 second period:

- The green LED on the keypad comes on for 5 s.,

- The buzzer stops,

- The cockpit door can now be opened

OPERATION FROM INSIDE (2)

NORMAL OPENING

Before normal door opening:

- check that the arming lever is in the disarmed position,

- check that the cabin pressure indicator is not flashing,

- hold the assist handle on the door frame,

- lift the door control handle fully up,

- push the door outward,

- move the door forward by using the door assist handle

The door locks when it is in fully open position

NORMAL CLOSING

For closing:

- push the gust lock and move the door rearward towards the frame,

- with the help of the door assist handle pull the door in,

- lower the control handle

The locking indicator turns from red to green which indicates the correct

SLIDE ARMING MECHANICAL OPERATION (2)

ARMING

In order to arm the evacuation device, the safety pin with the red flag

must be removed and stored away Push the arming control lever down

The red ARMED/green DISARMED indicator must show ARMED If

someone opens the armed door from the outside, by moving up the

exterior control handle, the slide arming lever moves automatically to

the disarmed position, which avoids accidental slide deployment

DISARMING

To disarm the door, lift the arming control lever fully up The

ARMED-DISARMED indicator must be green and indicate DISARMED

Install the safety pin with the red flag to avoid inadvertent movement of

the arming lever

DAMPER/EMERGENCY CYLINDER DESCRIPTION (3)

GENERAL

The damper and emergency operation cylinder, located on the support

arm, damp door movement during opening and closing sequences

Trang 35

Trang 36

DOOR DAMPER FUNCTION

The door damper cylinder function is to damp door movement during

opening and closing, in windy conditions for example Damping is done

by hydraulic fluid going through a restrictor as the operating rods extend

or retract

EMERGENCY FUNCTION

The damper and emergency operation cylinder forms an emergency

actuator that assists and improves the opening speed of the door in

emergency conditions When opened in an emergency situation, the

operating percussion lever lets the nitrogen bottle pressure act upon the

piston to push it out

NOTE: The door can be closed after an emergency opening

SERVICING

After an emergency operation of the door, the nitrogen bottle has to be

refilled, using the filling valve Remove the broken pieces of the shear

pin and the damaged diaphragm after an emergency operation Install a

new shear pin and a new diaphragm

NOTE: To fill the nitrogen bottle, take into account the temperature

and pressure chart values, if the damper/emergency cylinder

does not have a temperature-compensated pressure indicator
