12 Flashcards
It is a short to medium range, single aisle subsonic transport aircraft and is accepted as being one of the most technically advanced aircraft in the world.
A320
Hydraulically active systems are linked by means of an electrical pulse generated by a computer instead of the normal mechanical linkages.
Three cargo compartments are installed under the cabin floor
The aircraft is equipped with two high by-pass turbo fan engines mounted under the wings.
The APU is mounted in the tail and operates both on the ground and in the air.
The electrical power system consists of a three phase __ AC system and a __.
105/200V 400 Hz constant frequency
28V DC system
Electrical transients are acceptable for equipment.
Commercial supply has secondary priority.
Normally, the system produces AC current, which is then transformed into DC current. Each generator can supply the whole network.
In case of loss of normal AC generation, an emergency generator can supply the aircraft.
In case of total loss of AC generation, the aircraft can be supplied from the batteries. In this case, DC current can be transformed into AC current.
The air conditioning system operation is fully automatic. It provides a continual renewal of air and maintains a constant selected temperature in the three following zones: ___ which are independently controlled.
Cockpit, FWD Cabin and AFT Cabin,
In normal operation, pressurization control is fully automatic. The system consists of:

fly-by-wire control system
All flight control surfaces are:
- Electrically controlled,
- Hydraulically activated.
It can also be controlled mechanically. The pilots use the side sticks to fly the aircraft in pitch and roll (and in yaw, indirectly, through turn coordination). Computers interpret pilot inputs and move the flight control surfaces, as necessary, to carry out these orders.
stabilizer and rudder
However, regardless of the pilot’s inputs, computers prevent:
- Excessive maneuvers.
- Flight outside the safe-flight envelope
The flight controls consist of primary and secondary surfaces, which are hydraulically actuated.
- Primary surfaces are ailerons, elevators, and rudder.
- Secondary surfaces are slats, flaps, airbrakes, spoilers, and lift dumpers
There are a total of 10 emergency exits: -
LHS & RHS sliding windows in the flight deck.

Lift up the door control handle slowly 3 to 4 degrees and keep a watch on the Slide Armed warning light. Confirmation from Witness that the Slide Armed Warning Light is OFF, and says “Clear to Open the Door”.
If it does not illuminate, continue lifting it up to the OPEN position.
Push door outwards and forwards by using the door assist handle until the gust lock engages.
IF THE “SLIDE ARMED” CAPTION ILLUMINATES, THE DOOR IS STILL IN THE ARMED CONDITION. RESTOW THE HANDLE.
ALWAYS LIFT UP THE DOOR CONTROL HANDLE SLOWLY TO AVOID ACCIDENTAL DEPLOYMENT OF THE SLIDE.
CHECK “CABIN PRESSURE” CAPTION. IF RED LIGHT FLASHES:-
DO NOT OPEN THE DOOR - REPORT TO THE SCCM WHO WILL INFORM THE FLIGHT DECK. THE SLIDE SHOULD REMAIN DISARMED.
Normal Closing From Inside
- No debris or obstruction around the exit.
- Grasp assist handle on the door frame.
- Press gust lock release button.
- Pull door rearwards by door assist handle and pull into its frame
- Lower door control handle.
- Check door visual indicator reads “LOCKED” (in green).
Door Safety Precautions
- Never leave a door half open. It must be either fully open or locked closed.
- Before opening or closing a door the floor area across the width of the doorway and for 18” (0.5m)
inboard must be clear of debris or obstruction.
Emergency Opening From Inside
- Check slide is ARMED.
- Check outside conditions are safe.
- Grasp assist handle on door frame.
- Lift door control handle fully up and release it.
- Monitor slide inflation.
- If slide FAILS to inflate Pull Red manual inflation handle on right hand side of the door girt.
It should only be conducted once Evacuation Orders have been received and External Conditions are safe.
Emergency Opening of the door
DO NOT KEEP HOLD OF THE DOOR CONTROL HANDLE OR DOOR ASSIST HANDLE AS THE DOOR IS OPENED WITH FORCE BY THE PNEUMATIC SYSTEM.
IT WOULD PULL THE OPERATOR OUT OF THE AIRCRAFT.
SHOULD THE PNEUMATIC SYSTEM FAIL, PUSH THE DOOR OPEN MANUALLY BY USING THE DOOR ASSIST HANDLE.
Each cabin door can be opened from the outside. Opening instructions are written next to the external door control handle (opening handle).
Note: If a cabin door is opened from the outside, and the slide is in the Armed mode, the slide automatically gets disarmed.
Normal Opening From Outside:
- Look through the observation window to ensure Cabin Pressure Warning light is off.
- If Off, push the flap to grasp the handle.
- Lift the handle up to the horizontal green line.
- Pull the door outward and forward, till the gust lock engages.
- Restow the handle to the completely flushed position.
SLIDE
- The slide at the four Type I doors are all single lane, and can be detached and separated from the aircraft.
- There is a dual lane overwing ramp slide at the aft edge of each wing
- All are equipped with a manual inflation system in case the automatic inflation system fails during
operation. Slides take approximately 4 to 6 seconds to inflate.
The inflation reservoir sensors are connected to the __ and the pressure of the inflation cylinder is indicated on the __
CIDS
FAP.
The slides at the four Type I doors are all single lane, and can be detached and separated and converted to floatation devices in the event of a ditching.
All are equipped with a manual inflation system in case the automatic inflation system fails during operation. The Slides deploy directly to the ground and Hand Grips are stitched to the sides. The Slides are illuminated by integral lighting strips. Slides take approximately 4 to 6 seconds to inflate.
It is visible through a viewer on the front of the slide- pack cover, indicates whether the pressure in the gas inflation system is sufficient. This must be checked during pre-flight.
Pressure gauge
Preflight Check of Pressure Gauge
The slide pack pressure gauge needle visible through a viewer must indicate in the green band. Pressure varies with temperature and an abnormally low reading will be obtained after a long flight. In this case, check the gauge again after about 45 minutes, when the pack will have warmed to the surrounding temperature.
Operation
When a door is opened with the slide armed, the pneumatic system forces the door fully open. Because the slide girt bar is held in floor latches, the slide is pulled out of its container and will fall outside the aircraft. When the slide has dropped approximately 15” (38 cms), it will inflate automatically.
Manual Inflation Of Door Slide
All Slides are provided with a manual inflation system in case the automatic inflation fails during operation. The Red Manual Inflation Handle is located on the RHS of the door girt.
Using As A Hand Held Slide
If a slide fails to inflate by any means, it will hang down outside the aircraft. Four people should climb down the slide and extend it using the handgrips. It can then be held at an angle to support evacuating passengers.
Cabin Crew evacuation commands to passengers in this case will be- “SIT AND SLIDE”.
AS THE DOOR OPENS RELEASE THE GRIP ON THE DOOR CONTROL HANDLE.
HOLD ONTO THE DOOR FRAME ASSIST HANDLE AND GUARD THE DOOR EXIT UNTIL FULL INFLATION IS COMPLETE.
THE SLIDE INFLATION SEQUENCE TAKES 4 - 6 SECONDS.
IF THE SLIDE PACK IS WITHDRAWN BUT DOES NOT FALL OUTSIDE THE AIRCRAFT, PUSH IT OVERBOARD WITH YOUR LEG.
Method of Detaching and Separating From The Aircraft
Step 1 – To detach the slide from the girt, pull on the girt cover to expose the white detach handle
Step 2– Pull the white DETACH HANDLE completely free of the slide (until the slide is unlaced from the girt extension). When detached from the girt the slide is still connected to the aircraft by a mooring line which has one end tied to the girt bar.
Step 3 – To Separate the mooring line
To SEPERATE the mooring line cut the line with the hook knife. To use the the knife remove from its stowage. The Blade is curved with a single cutting edge on the inside. Always replace the knife in its stowage after use.
The mooring line will break if the aircraft sinks before it can be cut.
Four inward opening Type III emergency exits are provided, two on either side of the fuselage at seat rows 12 & 14 in the cabin. They can be located in darkness or smoke by sidewall mounted emergency lights and an exit marking sign.
An Over-Wing escape ramp slide assembly, consisting of a dual lane ramp with a dual lane slide is contained in an exterior fuselage compartment near the aft edge (root) of each wing. The slides are always armed and deploy when the exit is removed (opened from inside) or pushed in from the outside.
In an emergency the __situated on both sides of the emergency exit are illuminated.

- Monitor ramp slide inflation.
- If the Ramp Slide fails to inflate Pull the red manual inflation handle.
The weight of the Over-Wing exit is__
15Kg (32lbs).
Emergency Opening From Outside
Push the red flap and the emergency exit collapses inside the aircraft.
The ramp slide automatically deploys and inflates if the window is pushed in by the outside red flaps.
In a ground evacuation, passengers leaving from an Over-Wing exit are directed aft and ordered to “RUN AND SLIDE”.
In a ditching evacuation passengers leaving from an Over-Wing exit are directed to the nearest available group of passengers using the leading edge of the wing.
The Over-Wing ramp slides are fitted with integral emergency lighting strips.
Location Of Over-Wing Ramp Slide
The Over-Wing Ramp slide is stowed in the wing / fuselage fairing aft of the emergency exits.
Over-Wing Ramp Slide Deployment And Inflation
When one of the two emergency exits is opened, the ramp slide deploys and inflates on that side. Inflation takes only 4-6 seconds.
Manual Inflation
The ramp slides are equipped with a manual inflation system in case the automatic inflation fails during operation. The Red Manual Inflation Handle is provided at the top inner corner of each frame when the exit is removed and must be pulled down to inflate the ramp slide
Damaged Over-Wing Slide Operation
In case the Over-Wing Ramp slide has been damaged or does not inflate by any means,
it can still be used as a hand held slide. Locate the snap hook and attach to hook attachment point on the wing.
Four ABP’s must hold the slide by using the two handles installed on each side of the ramp slide.
Exit Technique
To avoid injuries to the head and body when getting out of the exit, leave by the Leg-Body-Leg technique.
Wing Walkways
The ground evacuation route from an Over-Wing exit is
AFT on the non- skid surface to the dual lane ramp.
ALWAYS ENSURE THE COVER OVER THE EMERGENCY HANDLE IS FITTED AS THIS PREVENTS THE HANDLE BEING USED AS A HANDHOLD. THE SLIDE-ARMED INDICATOR IS NOT ILLUMINATED.
IN AN EMERGENCY LANDING OR DITCHING, THE EXITS MUST NOT BE REMOVED UNTIL THE AIRCRAFT HAS FINALLY STOPPED.
THE OVER-WING RAMP SLIDE SHOULD ONLY BE USED FOR GROUND EVACUATION.IN AN EMERGENCY LANDING OR DITCHING, THE EXITS MUST NOT BE REMOVED UNTIL THE AIRCRAFT HAS FINALLY STOPPED.
