PASSENGER DOORS/SLIDE ARMING MECHANICAL OPERATION

ARMING

- In order to arm the evacuation device, the safetypin 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.Opening an armed door from outside:- If someone opens the armed door from the outside,by moving up the exterior control handle, the slidearming lever moves automatically to the disarmedposition, which avoids accidental slide deployment.

DISARMING

- To disarm the door, lift the arming control leverfully up. The ARMED-DISARMED indicator must be greenand indicate DISARMED.- Install the safety pin with the red flag to avoidinadvertent movement of the arming lever.

PASSENGER DOORS/LOCKING MECHANISM DESCRIPTION

LOCKING HOOK

The locking hook engages on a roller mounted on thedoor frames.The door is locked by a hook.

SAFETY PIN

A safety pin blocks the door even if a double mechanicalfailure in the locking mechanism and the liftingmechanism occurs.The safety pin prevents any upward door movement.

LOCKING SHAFT

The locking shaft is locked in an over centeredposition.An arm on the locking shaft forms the visual lockingindicator.The locking shaft is connected to the hook by a rodand bellcrank.

SPRING ROD

The overcentered position is maintained by a clearanceeven if structural deformation occurs.A spring rod maintains the locking shaft in anovercentered position.

LOWERING SHAFT

The door cannot be lowered in the open position whilebeyond the door frame.The lowering shaft mechanism locks the control handleto prevent the door from being lowered when not incontact with the door sill.

EMERGENCY CONTROL HANDLE

The emergency control handle is located far from theinner control handle.It is connected via rods and levers to the girt baractuating mechanism.

GEAR BOX

The shaft of the door central handles is coupled viaa gear box so that the outer-handle will not move whenthe door is lifted by operation of the inner handle.The gear box is connected by rods to the locking shaftand lifting lever.

DISARMING MECHANISM

When the outer control handle is operated, the releasemechanism of the emergency escape slide/raft isreturned to the "disarmed" position.A cam disk and a roller connect the emergency controlhandle and the outer control handle.

LOCKING SYSTEM

The door is locked by a hook located at the top ofthe door.Door locking is monitored on the ECAM by proximityswitches.One inner handle and one outer handle operate the doorlocking mechanism.The shafts of these handles are coupled via a controlmechanism which disarms the slide release mechanismwhen the outer handle is moved.It also prevents the operation of the outer handle ifthe inner handle is moved.

EMERGENCY SYSTEM

The emergency system consists of a slide control handlecontrolling the escape slide release mechanism, adamper and emergency operation cylinder, an escapeslide/raft packed in a container fitted in the fuselageunder the door and an inflation reservoir located abovethe door.

- In DISARMED mode, the damper and emergencyoperation cylinder damps the door movements.

- In ARMED mode, the damper and emergencyoperation cylinder powered by a gas bottleopens the door automatically.

INDICATING

For safe operation, two different kinds of indicatingsystems are fitted to the door :

- a electrical indicating system.- an mechanical indicating system.- ARMED/DISARMED indication placards.

Electrical indicating :- The warning lights are located below the doorwindow. They are visible, from the inside orthe outside, through the window.

When a person tries to open the door :- The white light comes on if the escape slideis in the ARMED mode.

- The red CABIN PRESSURE light flashes when thereis residual pressure in the cabin with slidedisarmed and engines not running.

Mechanical indicating :- A visual indicator on the top of the door showsif the door is LOCKED or UNLOCKED.

- A visual indicator above the slide controlhandle shows if the escape slide controlmechanism is in the ARMED or in the DISARMEDposition.

ARMED/DISARMED indication placards- There are two labels near the slide controlhandle, to avoid forgetting to disarm thedoor before opening.

EMERGENCY EXITS / DOORS OPERATION

NOTE : In this module the EMERGENCY EXITS / DOORSOPERATION is described on the A320 but theprinciple is the same for the A319.

OPERATION

Two emergency exits are located over each wing.The exits can be opened from the outside and the inside.Inside opening instructions are placarded on the exitframe.To open an exit, the cover flap must be removed.The "slide armed" indicator illuminates whiteimmediately.To unlock the latch mechanism, the control handle mustbe used.Pull down the control handle and pull exit top inwards.With free hand grasp the lower grip mould and liftexit.Turn exit inward and throw it out away from opening.Should the exit opening not initialize the automaticslide deployment, the red handle must be pulled formanual deployment.If a ditching line is provided, it has to be fixed tothe yellow fittings located in the exit frame and onthe wing.

EMERGENCY EXITS - DOOR DESCRIPTION/OPERATION

DESCRIPTION/OPERATION

For the evacuation of the passengers, there are fouremergency exit doors as well as four regularpassenger/crew doors.Two emergency exit doors are installed on each sideof the cabin, two forward of the wing leading edge andtwo aft of the wing trailing edge.The operation is similar to that of the normalpassenger doors.The forward left emergency exit door is larger in sizethan the others and is known as a 73" door.The three other emergency exits doors are 60" doors.Door operation from outside or inside and in emergencyis identical for all the emergency doors.The emergency exit door is installed with a supportarm and two guide arms which maintain door parallelto the fuselage in operation.The door mechanism is manually operated, it locks andkeeps the door in the safety closed position.It also unlocks and lifts the door before you can movethe unlocked door to the open position.The primary components of the door locking mechanismare:

- The door handle mechanism.- The locking shaft mechanism.- The balance mechanism.- The lifting mechanism.

The lifting mechanism will lock, unlock the door andoperate the lifting mechanism.This moves the door up so that the lateral guide rollerscome free from the fuse
