'A' CHECK ITEMS PRESS GAGE INDICATION CHECK (IF NOT CONNECTED TO CIDS) The PAX door escape slide and its inflation reservoir are located in a container at the bottom of the door. The inflation reservoir is part of the slide pack assembly. The inflation reservoir pressure can be checked through a pressure gage. Moreover, in relation with the Maintenance Planning Document (MPD), the door escape slide/raft pressure indication check must be performed every check A. A correct indication is shown when: the gage needle is in the green band or to the right of the green band. An incorrect indication is shown when the gage needle is to the left of the green cursor NOTE: THE CURSOR IS SENSITIVE TO TEMPERATURE CHANGES AND MOVES INDEPENDENTLY OF THE GAGE NEEDLE. IT REACTS TO TEMPERATURE CHANGES FASTER THAN THE GAS EXPANSION IN THE INFLATION RESERVOIR If the gage shows an incorrect indication wait for temperature conditions to become stable, then examine the gage again. If the gage continues to show an incorrect indication, you must replace the slide pack assembly.

BACKREST Pull the control handle marked "R" to adjust the backrest position. The system is controlled via two cables. A gas cylinder acts as a return spring for the backwards movement of the backrest. LUMBAR REST Two coaxial knobs enable vertical and horizontal lumbar rest adjustment. Rotation of the triangular knob is used for the depth adjustment of the lumbar rest. Rotation of the second serrated knob is used for the vertical movement of the lumbar rest. INBOARD ARMREST The inboard armrest can be raised vertically and stowed behind the backrest. The inboard armrest is on the pedestal side. Tilt angle adjustment is made using a knob installed on the front. SIDE STICK ARMREST The side stick armrest comprises the fixed arm, the carrier arm and the side stick table. The fixed arm is attached to the seat pan. It supports the carrier arm and side stick table assembly. Side stick table height adjustment is controlled by a knob installed on the armrest. The side stick table tilt angle is controlled by a knob installed on the front of the armrest. A position indicator installed on top of the table shows the table tilt. A wheel avoids interference between the armrest and the lateral console when the seat is moved forwards with the table fully inclined. SAFETY HARNESS The shoulder harness is put on an inertia reel which can be locked by a control lever installed behind the backrest.

EMERGENCY EQUIPMENT PAX DOOR ESC SLIDE DEPLOYMENT / DESCRIPTION (3) PASSENGER DOOR ESCAPE SLIDE DEPLOYMENT AND DESCRIPTION A slide deployment can be initiated whenever the door is opened in the emergency configuration. When the slide is armed it can be checked on a red indicator, located on the button of the slide decorative cover. As soon as the door handle is lifted the door opens and the escape slide is ejected from its container and the inflation system is activated. The deployment and inflation sequence is automatically initiated when the cabin door is opened. The slide deploys into its final usable position within 3 seconds. The escape slide is connected to the cabin floor by a girt extension which is attached to the girt bar at the door sill. Should the escape slide not inflate automatically a red manual inflation handle must be pulled. This handle is located on the girt extension. Let's have a look at the inflation system. The system is automatically activated as soon as the slide is ejected from its container. The valve regulator assembly incorporates a direct reading, temperature compensated pressure gage, which indicates the gas charge in the inflation reservoir, relative to ambient temperature. The gas stored within the inflation reservoir is discharged into the inflatable through flexible hoses and an aspirator. Ambient air is drawn in, through the flaps of the aspirator by the partial vacuum, created by the high velocity in the venturi. Then the flaps close and the remaining gas charge tops the inflatable up to its operating pressure. Inflation is therefore rapid and reservoir size is maintained. Restraint devices are used to control the deployment sequence.

The primary restraint mechanism is a precision fuse frangible link, which separates at a predetermined force value. In case of pressure loss, no fail handles, located on both sides of the runway end, allow the inflatable to be used as a hand-held evacuation chute. In the event of a ditching, grasp lines are fitted around the outside of the inflatable to facilitate the use of the slide as a flotation device. The slide is equipped with a lighting system. The lights located along the slide tubes and across the runway, are supplied from the aircraft emergency power supply units. The lights are automatically supplied with power when the slide is deployed. The escape slide can be disconnected from the aircraft floor whenever necessary. For disconnection the following steps must be taken. Lift the flap of the girt extension to gain access to the white disconnect handle and pull the handle. The girt extension incorporates a quick release feature, a daisy chain, which permits rapid detachment of the inflatable from the A/C. Once detached from the floor the inflatable drops from the A/C but remains attached to the girt bar by means of a string, which must be cut by using the knife located next to it, on the girt extension. The inflatable is then completely disconnected from the A/C.

PAX DOOR ESC SLD/RAFT DEPLOYMENT/DESCR.(OPT) (3) DESCRIPTION The FWD and rear cabin doors of the A320 are equipped with slide rafts. The inflation and deployment sequence is automatically initiated when the door is opened in the armed configuration. The slide raft is ejected out of its container, and remains folded by restraint devices which break at a determined pressure point to allow correct deployment. The slide raft is stowed in a container connected to the cabin door. NORMAL OPERATION As soon as the door handle is lifted, the door is pneumatically pushed open and the slide raft, fixed with a girt bar to the cabin floor, is pulled out of the container, drops down and inflates automatically. As the inflatable falls down, the inflation system is activated. The gas stored in the inflation cylinder is discharged through flexible hoses to the aspirators. The aspirator flaps open and ambient air is drawn in under partial vacuum, created by the high velocity in the venturi. Then the flaps close and the remaining gas, tops up the inflatable to its operational pressure. Should the automatic inflation system fail, the slide raft must be inflated manually.
TDTI / BUC / ATA 25
Issue: 01/01
MANUAL OPERATION For that, the red manual inflation handle located on the RH side of the girt extension must be pulled. A lighting system is fitted on both sides and also on the runway end of the inflatable. The power supply for this lighting system is provided from the cabin emergency power supply units. Two assist handles are located on both sides at the lower end of the inflatable, to allow assisting people to hold on. In case of a ditching, prior to door opening the survival kit must be connected to the slide raft. The survival kit is stored in the nearest overhead bin. Place the survival kit on the floor, FWD of the door and detach the lanyard from the girt bar. Pull the lanyard and the hook, to snap on the front of the survival kit. Then open the door. The slide raft drops out of the container and deploys. NOTE: In this module the PASSENGER DOOR SLIDE DEPLOYMENT/DESCRIPTION is described on the A320 but the principle is the same for the A318, the A319 and the A321.

OFFWING ESCAPE DESCRIPTION (3)
SLIDE
Austrian Technical Training School Notes - For Training Purposes Only
DEPLOYMENT
/
OFFWING ESCAPE SLIDE DEPLOYMENT The offwing escape slide is packed in a container assembly, which in turn is mounted into the center fuselage belly fairing. Two type 3 exits are located over each wing and are always in armed configuration. Two emergency lights underneath the wing exit illuminate the escape way leading to the escape slide which is pointed out with red fluorescent arrows. The opening of one wing exit will initiate the deployment sequence. The escape slide inflates automatically and is ejected out of its containers and deploys in approximately four seconds. The inflation system consists of an inflation cylinder, which is located in the aft cargo compartment. Activation of the release mechanism initiates the inflation sequence. The gas stored in the cylinder is discharged to the inflatable through flexible hoses and an aspirator. The aspirator flaps open and ambient air is drawn into the slide. The slide remains folded by restraint devices, which break at a predetermined force, to permit correct deployment. Two black arrows located on the ramp section indicate the direction of the escape route. A lighting system is provided on the slide. The lights are located on the ramps along the side tubes and across the runway end. A red manual inflation handle, located in each exit frame, must be pulled to manually activate the inflation and deployment sequence, in case of automatic release failure. If the slide is deployed but not inflated, it can still be used as a hand-held escape chute. On the ramp section top, a hook is located. This hook must be connected to an attachment fitting on the wing. Two red NO FAIL HANDLES are located on both sides of the escape slide on the way end. Four able bodied men must hold the deflated slide extended, by means of the no fail handles, to allow the passengers on the wing to descend.

EMER EXIT ESC SLD DEPLOYMENT/DESCR. (A321) (3) DESCRIPTION/DEPLOYMENT The escape slide for the type "C" doors, is stored underneath the door inside the fuselage. The inflation cylinder is located in the overhead bin, over the door. The cylinder is in a protection box and can be seen through a plexiglass window. The pressure can be checked on the pressure level indicator. For correct pressure the needle must be in the green section. To initiate the slide deployment, the door must be opened in the armed configuration. To open the door, uncover the control handle, lift the handle fully up, and release it.
A lighting system is fitted along both sides and at the bottom of the slide. The lights automatically come on during the slide deployment. They remain on as long as the emergency power supply operates. A re-entry strap is fixed on one side of the slide. A yellow life line is fixed along the outside of the inflation chambers on both sides. Red no-fail handles are located on both sides for assisting people to hold the slide in case it is used not inflated as an evacuation chute. The slide is slightly canted in order to deploy at a safe distance away from the engine.
CAUTION: DOOR OPENING PNEUMATICALLY ASSISTED WHEN OPENED IN ARMED MODE. The door opens outwards and then opens quickly. The escape slide in the meantime inflates and deploys completely. The escape slide is ready for use when the door is locked in the fully open position. Should the door open but the escape slide not inflate, a red handle for manual inflation is located in the door upper right hand frame. The transparent protective cover must be taken off and the red handle pulled to initiate the manual slide inflation. The escape slide for the type "C" doors is stowed in a special compartment in the fuselage, underneath the door. The deployment sequence starts as soon as the door is opened in armed configuration. One aspirator is connected to the inflation cylinder by means of a flexible hose. During the door opening the inflation cylinder regulator valve is actuated, and primary gas is supplied to the aspirator. The aspirator flaps open and outside air is drawn in. The flaps close as soon as the correct pressure is reached. The slide has a single lane sliding surface with a brake path at the bottom end, which slows down the speed of the evacuees.

EMER EXIT ESC SLD DISCONNECTION (A321) (3) DISCONNECTION The slide is slightly canted in order to deploy at a safe distance away from the engine. On the girt extension close to the door step are located the disconnect handle and a knife. The knife is on the LH side in a clearly marked pouch. A disconnect handle is located under a velcro flap marked "FOR DITCHING USE". To release the slide, lift the flap, grasp the white handle and pull. Should the slide not drop immediately, push down on the girt extension. The daisy-chain on the packboard releases, and the slide is free to drop. The slide remains attached to the A/C by means of a mooring line. This line must be cut by means of the hook knife.

CARGO LOADING Let's have a look to the A320 aft compartment loading and unloading. Switch on the compartment lights. Lower the two manual sill latches. Lowers the XZ-latches. Switch on the power on the control panel. The Cargo Loading System (CLS) is now ready to be used. The container itself lowers the overridable sill latches. When the container is over the lateral Power Drive Unit (PDU), move the joystick to the IN position. At the end of the lateral travel, move the joystick to the longitudinal position. The longitudinal Power Drive Units are now moving the container. When the container is in position, lift the corresponding XZlatch. It locks the container and de-energizes the PDU underneath it. Load the other containers by following the same procedure. When the last container is loaded, lift up the two manual sill latches then check that the two overridable sill latches are up. The cargo loading is now completed, you can switch OFF the power.
