It is very easy to find actual manuals for the A320 range of aircraft on the internet. For obvious reasons we cannot include them but even a quick source will lead you to a treasure-trove of information. Start your search with

‘A320 FCOM’

to find complete operation manuals. Almost all you find in there is applicable to this product.

AIRCRAFT GENERAL

The Airbus A320 family includes the A318, A319, A320, and A321, all medium range, subsonic narrow body civil aviation aircraft. Powered by two high-powered by-pass turbofan engines they seat up to 220 passengers.

AIR CONDITIONING & PNEUMATICS

The air conditioning system is fully automatic and provides continuous renewal of conditioned air in three zones:

COCKPIT, FWD CABIN and AFT CABIN. Temperatures in these three zones can be regulated independently. The air is supplied via the pneumatic systems using:

 two pack flow control valves two packs the mixing unit that combines air from the packs and the cabin

The cold air from the PACKs is mixed with the hot bleed air (taken from the engines or APU) by a mixing unit that is controlled by the zone regulator.

All control is done via the AIR COND panel on the overhead panel.

02 September 2014

Under normal operation conditions the complete pressurization is fully automatic. The system consists of:

 two Cabin Pressure Controllers outflow valve control panel two safety valves

In automatic operation pressurization is divided in 6 different modes

Ground

: before take-off and 1 minute after landing the outflow valve is fully open to equalize pressure with outside pressure.

Take-off

: just before take-off the system prepresurizes the cabin to avoid a sudden pressure increase

Climb

: cabin altitude is decreased to cruise level using input from vertical speed and other sensors

Cruise

: cabin pressure is maintained

Descent

: cabin altitude is increased to cruise level using input from vertical speed and other sensors

Abort

: in case of an aborted take-off the system will prevent the triggered climb mode from starting to decrease the pressure.

VENTILATION

SYSTEMS

Systems guide

Vol

02 September 2014

The ventilation of avionics is controlled by the Avionics Equipment Ventilation Controller (AEVC). It provides cooling of the avionics compartments using two fans, a heat exchanger that uses the outside skin of the aircraft to cool the air and an inlet and outlet valve. Only the automated mode is simulated and you can see the ventilation valve position on the CAB PRESS ECAM page. Battery, galley and toilet ventilation is provided by fans that draws air from the cabin and vents it overboard via a vent in the aircraft skin.

Do note that the AEVC is very loud and other sounds from the aircraft systems that are heard on other aircraft types are not heard on the Airbus A320 series.

APU

GENERAL

The Auxiliary Power Unit provides:

Bleed air for engine starting

Bleed air for air conditioning

Electrical power for all the buses

The APU can be used on the ground and in flight with the following limitations:

100% generator load up to 25,000 feet

Full pneumatic and hydraulic pressure up to 20,000 feet

Can be started using the battery up to 25,000 feet.

SYSTEM COMPONENTS

The APU consists of a gas turbine engine with an APU computer that manages the system. The air intake uses a electrically operated inlet flap and the exhaust vents in the tail cone. The electrical starter will start the engine when the inlet flap is fully opened. The fuel is taken from the left wing tank using a separate fuel pump.

AIR BLEED SYSTEM

Bleed air from the APU is selectable from the overhead panel and has priority over main engine bleed air as long as the APU BLEED pb is ON. The bleed air can start engines and provide the air condition system.

CONTROLS AND DISPLAYS

The APU ECAM page displays the parameters of the APU. For the gas turbine engine N (in %) and EGT (in °C) are available. The APU generator shows load (in %), voltage (in V) and frequency (in HZ) plus the connection to the bus (arrow when connected, nothing when not connected). Bleed air shows pressure (in PSI) plus the position of the valve (open or closed). All system messages are shown in green while within correct parameters, or amber when outside correct parameters.

The APU MASTER SW pb on the overhead APU panel is pressed (ON will show) to power up the APU computer, the fuel pump is activated and the air inlet is opened. When ON is shown the APU is ready to start.

The APU START pb starts the APU. When pressed it will show ON and the APU computer will command and control the startup. Aircraft batteries must be selected ON, even when the engine generators are online. When

On the ELEC panel the APU GEN pb will be dark when the APU generator is ON, and when pressed it will show OFF as the APU generator is taken of line. When there is any problem an amber FAULT will show and the ECAM will show more information.

On the AIR COND panel the APU BLEED pb will show ON when APU N speed is sufficient. When pushed the pb will be dark and the bleed air valve will close. When there is any problem an amber FAULT will show and the

ECAM will show more information.

AUTOFLIGHT

OVERVIEW

The following components are used by the pilot to interact with the autoflight system:

Flight Control Unit (FCU)

Multifunction Control and Display Units (MCDUs)

Sidesticks

Thrust levers

Primary Flight Display (PFD)

Navigation Display (ND)

The autoflight system is part of the Flight Management System (FMS). The FMS (including autopilots and autothrust system) is made up by two Flight Management Guidance Computers (FMGCs) and two Flight

Augmentation Computers (FACs).

FLIGHT MANAGEMENT

FLIGHT GUIDANCE

FLIGHT AUGMENTATION

Flight Management provides navigation, performance optimization and display management.

Flight Guidance provides autopilot commands (sent to the flight control computers), flight director commands (sent to the PFD) and thrust commands (sent to the autothrust systems).

Flight Augmentation provides flight envelope calculations, turn coordination and yaw damping.

PILOT INTERFACES

FLIGHT CONTROL UNIT

The FCU is located in the center of the glareshield and four knobs provide control for:

Airspeed

Heading (or track) or navigation modes

Climb or descent modes and/or

Vertical speed (or flight path angle)

There are two modes possible for airspeed, heading and vertical speed. Switching between modes is done by pulling (right click) the knob.

Selected Functions o

In selected mode the pilot controls speed and lateral/vertical navigation. After pulling the knob the pilot can rotate the knob to set the desired value. When the knob is pushed (left click) the current value for that function is inserted.

Managed Functions o

In managed mode the displays are dashed (note the FCU altitude windows is never dashed) and the control of speed and lateral/vertical navigation is managed by the FMS.

MULTIFUNCTION CONTROL AND DISPLAY UNIT

The MCDUs is the primary interface between pilot and FMS (and in our simulation it is also used to access some simulation functions.

SIDESTICK CONTROLLER

The sidestick controllers are used to fly the aircraft manually. Any strong input with these will deactivate the autopilot.

THRUST LEVERS

The thrust levers are used to manually control thrust or to select the desired autothrust mode. With both engines operating the autothrust range is between the idle and the FLX/MCT detents. With autothrust active the position of the thrust lever determines the maximum thrust level.

Vol

Normally the thrust levers are positioned in the climb (CL) detent at the thrust reduction altitude after takeoff and left there until the landing flare.

FLIGHT PHASES

The FMGC divides the complete flight into phases that normally will automatically switch to the next phase when certain conditions are met.

PERFORMANCE

The FMGC will minimize the flight cost through speed optimization. Depending on the Cost Index setting it will compute optimal targets for the following items:

Take off, approach and go around speed are calculated as a function of the TOW and performance model. Note that V1, V2 and Vr have to be manually entered (in our aircraft these speeds are calculated but can be overwritten.

CLB and DES speeds are computed as a function of the GW, Cost Index, environment (temperature, wind) and Cruise level. The speeds are NOT recalculated when the mode is active.

Cruise Mach is computed as the optimal speed and is updated continuously update to the current weather condition and F-PLN modifications.

Optimum Flight Level is calculated assuming a 5 minute minimum cruise flight. It is continuously update in flight.

ENGAGEMENT

The autopilot (two identical systems) are engaged by the AP1 and AP2 pb on the FCU. When engaged a green bar will show on the pb and the appropriate FMA annunciation is displayed. When a flight director is on when the autopilot is engaged, the autopilot engages in appropriate mode (OP CLMB and NAV) otherwise it will engage in the default guidance modes (HDG and V/S or TRK-FPA).

Either autopilot can be engaged seconds after takeoff.

DISENGAGEMENT

Disengage the autopilot by depressing the AP1 or AP1 button.

The autopilot is automatically disengaged by moving the side stick (or rudder pedals) a certain amount.

This will trigger a master warning.

The autopilot is automatically disengaged when the throttles are set above FLX/MCT on ground.

The autopilot is automatically disengaged when a normal law is exceeded or pitch or bank angle are excessive.

The autopilot is automatically disengaged during a non-precision approach when the aircraft reaches

MDA minus 50 feet .

AUTOPILOT & SPEED BRAKES

With the autopilot engaged the speed brakes are limited to ½ deflection. When autopilot is engaged with speed brakes extended beyond ½ they will retract to ½. Note this will cause a sudden pitch up.

AUTOTHRUST

The autothrust system reduces workload for the pilot, provides additional comfort for the passengers and reduces fuel use. Two main modes are included:

Fixed Thrust Modes o

Uses constant thrust; airspeed is controlled with pitch. Normally used for level changes when no specific vertical speed is required.

Variable Thrust Modes o

In variable thrust mode the airspeed remains constant by changing the amount of thrust.

Normally used for level flight or when a certain airspeed is required during level change.

AUTOTHRUST ARMING STATUS

When autothrust is OFF the thrust is controlled manually and corresponds to the position of the trust levers.

When autothrust is ARMED and the thrust levers are moved into the A/THR active the autothrust status changes to ACTIVE. The status is shown on the FMA (blue indicates armed mode and white indicates active mode).

Autothrust is automatically armed during takeoff when thrust levers are in the TOGA or FLX detent.

AUTOTHRUST ACTIVE STATUS

The autothrust system controls thrust only in active status. Both fixed (MCT, CLB, IDLE, THR) and variable thrust

(SPEED, MACH) modes are available in active status.

AUTOTHRUST DEACTIVATION

The autothrust system can be disabled by depressing the FCU A/THR pb or by retarding the throttles to the idle detent. A single chime and a short amber master caution illumination alerts the pilot.

AUTOTHRUST MODES

FIXED THRUST MODES

TOGO: Provides fixed maximum thrust and is only available when autothrust status is armed.

FLX: Flex thrust is used for reduced thrust takeoffs. Thrust is calculated using the assumed temperature as set in the MCDU.

MCT: Provides Maximum

Continuous Thrust at the current ambient conditions.

CLB: Provides fixed thrust equal to the climb thrust rating at current ambient conditions.

IDLE: Provides fixed idle thrust.

Only available in active autothrust status. Note the thrust levers can be anywhere in the autothrust range!

THR: When the thrust is not TOGA, FLX, MCT or CLB the fixed thrust is called THR.

VARIABLE THRUST MODES

SPEED: The autothrust system will provide variable thrust to maintain a set speed or a managed speed in level flight or when the aircraft follows a programmed flight path. Only available when autothrust is active.

MACH: Identical to speed mode but not available at low altitudes. The speed mode is automatically switched to Mach mode (and vice versa) at a preset altitude.

AUTOTHRUST/FLIGHT DIRECTOR/AUTOPILOT

The vertical guidance modes use pitch to maintain a target speed or a specific vertical path. If vertical guidance modes are used to control a target speed, autothrust uses a fixed thrust mode. If vertical guidance modes are

02 September 2014 used to control a specific vertical path, autothrust uses variable thrust to maintain target speed. When manually flown in fixed autothrust mode the flight director’s pitch command bar indicates the pitch needed to fly the desired speed.

ALPHA FLOOR

The alpha floor protection assists the pilot in recovering from dangerous low speed and high angle of attack by automatically setting TOGA thrust when:

Excessive angle of attack (alpha)

Excessive high nose up attitude

Windshear is detected

When the alpha floor conditions are no longer detected the autothrust system will stay in TOGA lock until the pilot disables auto throttle. It is recommended the pilot moves the throttle to the TOGA detent before depressing the FCU A/THR pb to avoid a power surge. After that the pilot can pull the throttle to the CL indent and engage the autothrust.

FLIGHT AUGMENTATION COMPUTERS

The FACs handle:

Yaw damping and turn coordination

Rudder trim

Flight envelope and maneuvering speed computations

Alpha floor protection

Windshear detection

Low energy detection

FLIGHT ENVELOPE

Many different speeds are calculated by the FACs are used by the autoflight system. These speeds include the minimum safe speed, maximum speed and never exceed speed. They also calculate the alpha floor speed. Most of these speeds are shown on the PFD airspeed indicator.

WINDSHEAR

The FACs will try to detect windshear and will warn the pilot of this dangerous condition. Windshear detection is only active below 1300 feet AGL in configuration 1 or greater. When detected the flight director will show an optimal pitch attitude and the aural warning “WINDSHEAR” will be heard.

LOW ENERGY WARNING

Between 2000 and 100 feet AGL the FACs will detect a low energy state (based on airspeed, descent angle and angle of attack) and will warn the pilot with an aural “SPEED SPEED SPEED” warning. Normally this warning will precede an alpha floor condition.

Flight guidance is provided for speed control, lateral navigation and (limited in this project) vertical navigation.

There are two types:

Selected Guidance: In this mode the aircraft will fly on autopilot using the settings on the FCU. You switch from managed mode to selected mode by pulling (right mouse click) the SPD, HDG and ALT knobs.

Managed Guidance: In this mode the airspeed is calculated by the FMS and differs per flight phase. The

FMS also provides managed lateral and vertical flight plan guidance following the flight plan that has been inserted in the MCDU. The FCU will show dashes in managed guidance. You switch from selected guidance to managed mode by pushing (left mouse click) the SPD, HDG or ALT knobs.

Please note the FCU altitude window will never be dashed.

When the autopilot is engaged or the flight director is activated the Flight Mode Annunciator (FMA) (at the top of the PFD) will also display the activated settings.

LATERAL GUIDANCE MODES

The lateral guidance modes keep the aircraft course to its destination.

SELECTED HEADING (OR TRACK) MODE

The heading (or track) mode will guide the aircraft on a heading (HDG) or track (TRK) and is the default lateral mode. The pilot activates it by pulling (right mouse click) the HDG button on the FCU. A digital display of the heading (track) will be shown on the FCU and HDG will be displayed on the FMA. Note this mode cannot be activated when LAND mode is activated.

If the knob is turned to the desired HDG (TRK) and pulled the aircraft will make the shortest turn to the selected HDG (TRK)

If the HDG knob is pulled but not turned the current HDG (TRK) is selected.

If the HDG knob is pulled first and turned the aircraft will turn in the direction of the turn.

If the HDG knob is turned but not pulled the selected value is cleared after a period that depends on the flight mode.

MANAGED NAVIGATION MODE

When a flight plan is available and activated the managed nav mode will guide the aircraft along the path stored in the FMS. It is activated by the pilot by pushing (left mouse click) the FCU HDG knob. The display will show dashes and the FMA will display NAV.

LOCALIZER LATERAL MODE

When the FCU LOC pb is pushed the loc lateral guidance mode is armed and the FGS will only use the localizer signal for lateral guidance. In the FMA LOC will be displayed and the LOC pb will illuminate. It can be used to intercept and track a localizer while maintaining a selected altitude. Note that a ILS frequency must be tuned and

TAKEOFF and GO-AROUND mode are not selected. To disarm press the LOC pb again.

GUIDANCE

In DES mode the aircraft is guided along the DES PATH. The SPD target can be selected or managed (with the speed to vary around the calculated optimal nominal descent speed. SPD CSTR is taken into account in the speed profile.

If the aircraft is above the DES PATH it will pitch down until the upper limit of the MANAGED SPD RANGE is reached. That speed will be kept and the aircraft will differentiate from the DES PATH. Extending ½ speed brakes will allow the aircraft to get back on the calculated path.

If the aircraft is below the DES PATH the aircraft will maintain the target speed until the DES PATH is reached.

Unfortunately FSX is not very strong with radios and we really wanted to stick to the default commands of FSX because a lot of people have hardware for these parts. So we went for practicality more than for getting the simulation exactly as the real aircraft. It’s a small price to pay for compatibility and usability.

The external doors and cargo hatches can be opened using a simulated page in the right MCD under the ACFT DOORS page. When the aircraft is stopped, engines are off and the parking brakes (or chocks) are set, you can open the doors via this menu. The door identifier will blink when the door is being opened or closed. This menu is not available when the aircraft is not stationary, with engines off and on parking brakes (or with wheel chocks activated).

All external doors in the Airbus A32x are conventional in design and operation and all door operation can be monitored on the ECAM DOORS page. The ECAM DOOR/OXY page will appear automatically:

ELECTRICAL

Vol

GENERAL

In normal operation the generation and distribution of electrical power is fully automated and does not need any interaction. Even when there are failures the systems will almost always be able to correct or activate alternate systems when needed. As with all overhead panels a dark panel with all lights off indicates systems without fault and in automatic mode.

AC GENERATION

AC power is distributed via the two AS buses. Each engine generator supplies one of the two buses but a tie connection allows one of the generators to provide both buses. The APU generator can be used as the sole source for all systems, excluding the galleys. Note that at high altitude the APU generator load capacity is decreased.

When available, Ground Power is able to provide all buses with electricity. The two batteries are connected to the buses via a static converter. An automated bus tie system interconnects all systems.

AC BUSES

There are 5 buses for AC power:

1.

2.

3.

4.

5.

AC1 Bus

AC2 Bus

AC ESS Bus

AC ESS SHED Bus

AC Ground/Flight (the latter is ignored)

DC GENERATION

The DC system powers the DC components, and is needed to start the APU when no EXT PWR is available. The DC electrical system is the first backup for the AC system and will power essential components when all AC generators are offline. In normal operation three transformer rectifiers (TRs) convert AC to DC and AC1 is the first source for DC power.

Two NICAD batteries connect to their own hot battery bus that is always active. The batteries are charged using the DC BAT bus and disconnected from all buses when they are not needed and fully charged. The batteries use proprietary code so they will not lose power as fast as standard FSX batteries. Depending on your use you should be able to run the systems on battery for up to half an hour. Of course it is advised to either connect external power of power up the APU to avoid your aircraft going cold and dead unexpected.

ELEC OVERHEAD PANEL

All the normal operations for the electrical system are done via pushbuttons on the overhead ELEC panel.

The battery voltage for both batteries is shown in the two small LCDs. These displays will always be on when the battery is installed.

The BAT pbs (BAT 1 & BAT 2) are off when in AUTO mode. The batteries will automatically connect when the APU is started without EXT PWR, when voltage drops below 26.5 (to charge) or when the aircraft is on ground and no other electrical sources are available. They will show FAULT when the batteries are disconnected because of a fault. When the pb is clicked OFF will show and the battery will be disconnected.

The IDG pb (IDG 1 & IDG 2) will disconnect the generator from the engine, only ground maintenance can reset this. The switch is protected by a switch guard.

The EXT PWR pb will be off when no external power is available. It will show AVAIL when power is available. When pushed ON will show and the external power will be connected to the aircraft buses. It is recommended to deselect EXT PWR before the ground crew disconnects.

RELEASED OUT: off, manual, alternate, shut down

A push button that shows two dots is only partially used.

FLIGHT CONTROLS

GENERAL

The Sidesticks are used to control pitch and roll. The input from the pilot is interpreted by the flight computers and these move the flight controls. The flight computers however will ignore any input that would cause excessive maneuvers or would put the aircraft outside the safe flight envelope.

The flight control surfaces are electrically controlled and hydraulically activated.

COCKPIT CONTROLS

Two side stick controllers for pitch and roll (these are not mechanically connected)

Two pairs of pedals (interconnected) that mechanically control the rudder

A speed brake control lever

Two hand wheels to mechanically control Trimmable Horizontal Stabilizer (THS)

A switch to control rudder trim

A tiller that is used to steer the aircraft at low speed on the ground (note this is animated but cannot be used to steer.)

Note there is no aileron trim control.

02 September 2014

PITCH CONTROL

The two elevators and THS control pitch. The pitch is normally controlled by ELAC 2 and uses the green and yellow hydraulic systems. The THS uses three electrical motors. Mechanical control using the THS always overrides the electrical controls, but has limited elevator travel.

ROLL CONTROL

One aileron and four spoilers on each wing control roll. Roll control is normally controlled by ELAC 1, using the blue and green hydraulic systems. Spoiler control uses SEC 3, using the green, yellow of blue hydraulic systems.

YAW CONTROL

In flight yaw control is fully automatic and the yaw orders are computed by the ELACs and handled by the FACs.

One rudder surface is used. Mechanical control is always possible and overrides the electrical controls. The single rudder surface is moved by 3 hydraulic jacks using the green hydraulic system with a yellow hydraulic backup.

Rudder deflection is limited as a function of speed.

Yaw trim is achieved by two electric motors. In automatic flight the FACs and FMCG controls the rudder. In manual mode the RUD TRIM rotary control on the pedestal can be used. The reset button will center the rudder.

Rudder trim and reset is NOT active when A/P is used.

FLARE MODE

When passing 50 feet on landing the flight mode changes to flare mode and the attitude is maintained. At 30 feet the aircraft will start a pitch down maneuver to 2° nose down and gentle positive pilot action is required.

SPEED BRAKES AND GROUND SPOILER CONTROL

Spoiler 2, 3 and 4 are used as speed brakes and controlled by the speed brake lever. Speed brakes cannot be used in flaps configuration 3 and FULL or when angle of attack protection is active.

Ground spoilers are armed when the speed brakes control lever is pulled in to armed position. It uses spoiler 1 to

5. They will extend automatically:

At landing when both main wheels touch down and throttle is at forward idle

At take off when reverse is selected on at least one engine and speed is over 75 knots.

OVERHEAD PANEL CONTROLS

There are two FLT CTL panels on the overhead panel. When the corresponding system is ON and without fault the pb will be dark. When clicked OFF will show and the corresponding computer will be deactivated. When clicked again the computer will reset and restart. The two panels are mixed so each crew member will be able to control at least one ELAC, SEC and FAC.

PROTECTIONS

The normal law provides complete flight envelope protection:

Load Factor limitation o

+2.5 g <-> -1.0 g flaps retracted o

+2.0 <-> 0.0 g flaps extended

Pitch Attitude protection o

30° nose up in configuration 0 to 3 o

25° nose up in configuration full o

15° nose down

Bank Angle protection o

33° bank angle o

When the sidestick is kept full right or left the aircraft will bank to 67°, when sidestick is released it bank angle will go back to 30°

High Angle of Attack protection o

When angle of attack exceeds α protection the High Angle of Attach Protection kicks in. It will allow AoA to go to α max but not beyond. This protects against stall and windshear. A/P will disconnect in this mode.

High speed protection o

When the speed exceeds safe limits the engines will throttle down and when needed, speed brakes will be deployed.

FLAPS AND SLATS

Lift augmentation is achieved on each wing using:

Two double-slotted flap surfaces

Five slat surfaces

They are hydraulically moved and electrically signaled and operated using the FLAPS lever that has 5 positions. The upper ECAM always shows the flaps/slats position both in a small diagram and in position (with animation when the flaps/slats are moving).

If configuration 0 is not selected after takeoff, the flaps will automatically retract at 210 Kts.

ENGINE FEED

The main fuel pumps feed fuel from the wing tanks to the engines using two fuel pumps in each wing tank.

MAIN COMPONENTS

Tank pumps

, two in each wing tank, normally both activated.

Cross feed valve

, allows the left and right systems to be connected and to feed both engines from one wing tank, normally closed.

Engine low pressure valves

, when closed (by using the engine master switch or the ENG FIRE PUSH button) they cut the fuel flow to the engine, normally open.

Suction valves

, when open they allow the engines to be gravity-fed from the wing tanks. Normally the fuel pump action will close these valves.

FUEL FEED SEQUENCE

During engine start (and for 2 minutes after engine start) engines are fueled from the wing tanks.

When slats are extended engines are fueled from the wing tanks.

When wing tanks are full engines are fueled from the wing tanks (to allow fuel expansion) until an ‘under level’ sensor is triggered. While engines are fueled from the wing tanks, fuel is transferred from the center tank to the wing tanks. When the inner wing tank reaches 750 kg of fuel, the outer wing tank fuel content will be transferred to the inner tanks.

CENTRE FUEL TANK TRANSFER

The Fuel Level Sensing Control Unit (FLSCU) controls the transfer of fuel from the centre tank to the wing tanks.

When 500 KG of fuel has been used (from a wing tank) the FLSCU will start the transfer of fuel from the centre tank to the wing tank. When the FLSCU senses the wing tank is full the transfer is stopped. This system ensures that the wing tanks are always as full as possible and that the wing tanks fuel levels are always as equal as possible.

NOTE: to avoid an incorrect fuel load, always fill the wing tanks complete before adding fuel to the center tank. If you see the MODE SEL button light up with a amber FAULT the most obvious cause is that the center contains too much fuel and the wing tanks too little.

GENERAL

There are three separate and fully independent hydraulic systems, Green, Blue and Yellow, each with its own pump(s), reservoir and accumulator. In normal operation the system is fully automated and does not need any interaction.

The Green system can be pressurized by an engine-driven pump and can use the Yellow system via the connection Power Transfer Unit (PTU).

The Yellow system can be can be pressurized by an engine-driven pump and can use the Green system via the connecting PTU. Additionally an electric and a hand pump (not simulated) can be used.

The Blue system is powered by an electric pump or the Ram Air Turbine (not simulated) and is mainly intended as a backup emergency system.

The Power Transfer Unit is used to transfer pressure between the Green and Yellow systems when differential pressure exceeds a set limit.

ECAM HYD PAGE

All pumps are indicated by triangles on the ECAM. When the pump is off it is a white open triangle, when the pump is ON and pressure is normal a green triangle is shown. An amber triangle means the pump is on but pressure too low.

HYD OVERHEAD PANEL

The Hydraulic panel on the overhead panel allows the crew to interact with the system in case of failures. As with all overhead panels a completely dark panel indicates is in AUTO mode and there are no problems.

The ENG PUMP pb (ENG 1 PUMP & ENG 2 PUMP) are dark in AUTO mode (ON and pressure within limits). When there is a problem FAULT will show. When pushed OFF will show and the pump will be offline and the system depressurize.

The Blue Electric Pump pb (ELEC PUMP) is always active when one of the AC buses has power. When pushed (after lifting the switch guard) OFF will show and the system will depressurize. When the pump is on but pressure too low FAULT will show. The ECAM will show more details on that.

The Yellow Electric Pump pb (ELEC PUMP) is dark by default, indicating it is not active. When pushed ON will show and the pump will energize. FAULT will show if there are problems, check the ECAM for more details. Note the Yellow system will pressurize the flight controls (via the PTU) when the main engines are off!

The Power Transfer Unit (PTU) is default dark and in AUTO mode. When differential pressure is detected it will pressurize the low pressure system. When clicked OFF will show and the Green and Yellow systems will not be connected. FAULT will show if there is a problem, the ECAM will display the problems.

ICE AND RAIN PROTECTION

Using the ice and rain protection systems allow the unrestricted use of the aircraft in severe icing conditions and heavy rain fall. Electrical heating is provide for flight compartment windows, probes, pitot tubes, static ports and waste water drains (though the latter is not simulated). Hot bleed air heating is provided for the engines nacelle leading edges and outboard leading edge of each wing.

Rain protection comes in the form of wipers on the front windshields and an optional rain repellent system.

WING ANTI-ICE PROTECTION SYSTEM

To prevent ice buildup on the outboard wing slats, hot engine bleed air is sent into ducts on the wing leading edge. The WING pb on the ANTI ICE overhead panel controls the system and this is displayed by the wing anti-ice valve symbols on the ECAM BLEED system display.

PROBE / WINDOW ANTI-ICE PROTECTION SYSTEM

The probe heat computers provide automated protection using electrical heating coils against icing on the front windows, pitot tubes, static ports, TAT probe and AoA probes. It can be manually controlled (overriding the automated systems) using the PROBE/WINDOW HEAT pb.

When the pb is not illuminated the system is running in automated mode.

To prevent ice buildup on the engine nacelle leading edges, hot engine bleed air is used. It is manually controlled by the PROBE/WINDOW HEAT pb. When engine anti-ice is selected engine idle speed will increase and continuous ignition is automatically selected.

RAIN REMOVAL

Both front windshields have individual windshield wipers controlled by three position switches on the overhead panel. Activating them on a dry windshield might cause damage to the windshield. Using the wipers at airspeed over 240 knots might result is not advised.

LANDING GEAR AND BRAKES

GENERAL

The landing gear consists of a steerable nose gear with two wheels and two main landing gears with two wheels.

The nose gear retracts forward and does not have any brakes. The main gear retracts inboard and is equipped with carbon disk brakes. An auto brake system and anti-skid systems are available to assist the crew in halting the aircraft under less favorable conditions. An interlock system prevents gear retraction when the aircraft is on the ground. In case of total hydraulic failure the gear can be extended with a manual crank handle. On retraction the main gear is automatically braked using the normal brakes. The nose gear is braked with a friction band on retraction.

MAIN WHEEL BRAKES

The brakes are operated by the brake pedals or the autobrake system via the Green hydraulic system.

Temperature sensors in each main wheel display the temperature on the ECAM WHEELS page. Takeoff is not allowed before the brakes are below 300°C.

ANTI-SKID

The anti-skid system operates when wheel skid is detected and will provide maximum brake efficiency. The system is always active, when running from an alternate source it might not be available.

AUTOBRAKES

The autobrake system has three settings. LOW, MED or MAX selected by pbs. ON will show on the selected setting. When the aircraft is close to the selected rate a green DECEL will show. Pressing the illuminated pb deactivates the system. Green hydraulic pressure has to be available and the A/SKID & NW STRG needs to be active. The brakes are activated by spoiler extension.

BRAKE-FAN

The brake fans provide additional cooling when the brakes are overheating (amber temperature displayed).

Activate them during taxi.

NAVIGATION

The navigation system has the following main components

Navigation receivers

Radar altimeter, transponders

Two ADIRS

Two FMGCs

Pilot interaction with these system uses:

Multifunction Control and Display Units (MCDUs),

Flight Control Unit (FCU)

Transponder control panels

ADIRS control panel

Radio Management Panels (RMPs)

ADIRS

The Air Data Inertial Reference

System supplies data such as baro altitude, speed, angle of attack, temperature, attitude, track, heading, acceleration and aircraft position. The Inertial Reference

System uses three separate units to determine its position, and these have to be aligned before the aircraft is moved.

The ON BAT light will be illuminated when one or more IRS is supplied only by the aircraft battery; it will also light up for a short while at the beginning of alignment.

The IR pb sw will display OFF when the system is not connected to the other systems and FAULT when the when IRS alignment is lost.

The three rotary mode selectors will switch between OFF, NAV (normal mode or operation) and ATT (not simulated).

The ADR pb sw can be pushed to disconnect one or more of the systems (OFF) and will display FAULT when the ECAM systems detected a fault in the Air Data Reference data.

Note: There are differences in setup of ADIRS systems between Airbus models and even airlines, this also means there are slight differences in how the ADIRS is being used.

NAVIGATION RADIOS

The navigation radios are set in the MCDU on the RADIO NAV page. You enter this page by pressing the RADNAV key. Tuning to a station is as simple as entering the frequency (like 117.50) or the name (like SPA) on the scratchpad and then clicking the button next to the radio you want to tune. If there is more than one station with the same name or frequency the nearest is always selected.

GPWS

The Ground Proximity Warning System (GPWS) generates audio and visual warnings when the aircraft is in a dangerous condition;

Mode 1: Excessive rate of descent

Mode 2: Excessive ground closure rate

Mode 3: Altitude loss after takeoff

Mode 4: Unsafe terrain clearance

Mode 5: Excessive deviation from glide path

Note that some airports have approaches that will trigger the GPWS warnings. Be prepared for this.

RUNWAY AWARENESS AND ADVISORY SYSTEM

The Runway Awareness and Advisory System (RAAS) is designed to provide to crews information about the aircraft's position relative to an airport's runway while operating at an airport. RAAS is a software upgrade to the later-model Enhanced Ground Proximity Warning Systems. It is designed to prevent runway incursion incidents.

The RAAS is automatically triggered and does not have any user interface. See Vol1 for more information.

The Airbus A320 and A321 are powered by two CFM56 or IAE V2500 turbofan engines. Though these engines have slightly different characteristics, these differences are hard to notice for the crew as they are controlled by

FADEC systems. The type rating of an Airbus pilot does not even mention the engine type.

FADEC

The Full Authority Digital Engine Control system (also called the Electronic Control Unit ECU) performs these functions:

Gas Generation Control (fuel flow, acceleration, idle settings)

Engine Limit Protection (overspeed and EGT monitoring)

Power Management (thrust rating)

Automatic Starting Sequence

Thrust Reverser Control

Fuel Recirculation Control

ECU Cooling

Detection, Isolation and Recording of failures.

THRUST CONTROL SYSTEM

Thrust Control is managed by the FADEC on each engine. Thrust selection is done by means of the thrust levers when in manual mode or by the FMGS when in automatic mode. Thrust rating limit (maximum amount of power) is provided by the thrust lever position.

THRUST LEVERS

In automatic mode the trust levers should be seen as mode selectors and in many flights the throttles are not touched in the complete flight (from shortly after take-off to shortly before landing) and stay in CLIMB mode the whole flight.

The thrust levers can only be moved manually between 5 detents (stops) over 4 operating segments. Auto throttle is on only active in the range between idle and climb

(including bit detents). Thrust Rating limit is computed from the thrust lever position, when between detents the FADEC will select the rating limit of the higher detent.

The engines are in manual mode when the thrust levers are outside the operating range and the ATS is not activated. In manual mode the pilot operates the engines by moving the thrust levers between idle and T.O./G.A.

The FADEC will calculate the optimal N1 rating for each position.

When on ground and the thrust levers are in the FLEX detent the FADEC will select a thrust rating based on flex

T.O temperature (set in MCDU) greater than the current TAT. If no flex temperature is set MCT thrust will be used. MAX TO power is always available by pushing the levers full forward.

AUOMATIC MODE

In autothrust mode (A/THR activated) the thrust is calculated by the FMGC but limited to the mode setting of the thrust levers. When an alpha-floor condition is detected the FMCG will automatically select alpha-floor mode and full power is available.

The FMA will flash white LVR CLB to remind the pilot to select climb mode above the thrust reduction altitude.

RADIO NAVIGATION

Radio Navaids are used to display positional information and by the aircraft computer to calculate it’s position.

Tuning can be done automatically by the FMGC or manually using the MCDU RADNAV or PROG pages. When the

FMGC fails the Radio Management Panel can be used. Manual tuning always has priority.

NAVAID SELECTION ON MCDU PAGES

The navaids that are tuned by the FMGC can be seen on three MCDU pages:

RADIO NAV page

Tuning can here be done by entering the frequency or name.

The nearest navaid that matches will be used.

AUTOTUNE VOR

The following priority rules are used for VOR tuning:

Radio position computation

Navaid specifically for the active leg

AUTOTUNE ADF/DME

The following priority rules are used for DME and ADF tuning:

ADF in F-PLN and/or fix in the approach is a TO waypoint

An ILS is autotuned when the departure runway has a ILS (during PREFLIGHT AND TAKE OFF mode) and when the

F-PLN approach mode has an ILS in all other modes.

SEATBELT/NO SMOKING

The no smoking signs should be left ON during all operational flights. The seatbelt sign behavior is semiautomated when in AUTO and the seatbelts sign will be lit when the aircraft is below 10,000 feet. Any time the indication for the passengers changes a chime is played in the cabin.

WEATHER RADAR

The Collins WXR (weather radar) detects precipitations by means of a high frequency radar. The radar beam reflects of rain drops or hail and is received by the system. The radar returns are then displayed in a calibrated gain color system. When the radar beam hits the ground (or other solid objects) it is also returned. The Collins

WXR is able to eliminate ground clutter to provide a clearer image. However the Ground Mapping option does allow the user to scan the ground and pick up coastlines and other important ground features.

The fully automated multiscan mode sets the gain and tilt automatic to the ideal settings for each stage of the flight, reducing pilot workload. Multiscan operates the weather radar as a highly experienced would do manual.

The pilot is advised to keep in mind that at the cold top of clouds the water is mostly in ice crystals and super cooled water. These so not reflect the radar very effectively.

Scanning a cloud from top to bottom using the manual scan will reflect that as reflections will increase near the bottom of the cloud where all the precipitation is in the form of liquid water and the density of droplets highest.

As radar beams travel in a straight line the curvature of the earth is important. Low clouds can be invisible at a distance because they are hidden by the curvature of the surface even though they are in range. In multiscan mode the radar is able to skim the radar horizon (tilting the beam so it remains just above the horizon). Keep in mind that over a distance of 320 NM the curvature of the earth causes the earth’s surface to move down approximately 65,000 feet. So if the aircraft is at 25,000 feet the earth’s surface is about

90,000 feet below the aircraft 320 NM in front of the aircraft. The antenna is stabilized up a 45 degree bank, meaning the radar sweep will be level with the horizon up to 45 degrees. It is also stabilized for pitch.

AUTO MULTISCAN MODE

In auto mode (MULTISCAN switch set to AUTO) the tilt is automatically controlled. Two beams (upper and lower) are merged together to become one picture representing weather in the possible vertical flight path of aircraft.

Also in MULTISCAN AUTO mode the GCS (ground clutter suspension) is usually in AUTO mode and so the ground clutter will be suppressed. Only when GCS switch is set to spring loaded OFF-Position the ground clutter would be visible but GCS is also only available in MULTISCAN AUTO mode, not in MAN mode!

In manual mode (MULTISCAN switch to MAN) the radar beam is controlled via the TILT rotary knob. The flight crew uses the following three features to operate the Collins WXR2100 Weather Radar in the Airbus A318/319 family (if MULTISCAN MAN is selected):

Gain control, which adjusts the sensitivity of the receiver (and should usually be set to AUTO).

Antenna tilt, that controls the angle between the center of the beam and the horizon

Range control of the ND, that has an essential influence on the optimum tilt setting

The following features are modeled respectively can be operated in the Aerosoft A318/319 Airbus:

GAIN

(-15<>+15): Sets the sensitivity of the receiver.

MULTISCAN

(MAN and AUTO): Multiscan mode is in Auto, off in Man.

GCS

(OFF and AUTO): Ground Clutter Suppression.

TILT

( -15° <> +15°): Controls the pitch of the radar transmitter.

Range control: Range control is set by the standard Navigation Display Range setting.

Whereas the range control is handled on the EFIS for the other settings the WXR panel is used. To get the maximum range / display it is necessary to have set FSX SETTINGS / WEATHER / CLOUD DRAW DISTANCE to the maximum (if a weather tool is used apply the same settings to it).

WEATHER RADAR DISPLAY

The weather radar display is depicted on the ND in any mode except PLAN. The selected ND range scale will control the weather radar range.

The radar returns will appear in black, green, yellow, red or magenta depending on the precipitation intensity.

The antenna tilt angle will be displayed in the lower right-hand corner of the ND and is the angle between the horizon and the radar beam axis. When MULTISCAN manual calibration mode is selected, MAN and the setting appear in blue whereas in AUTO mode the setting appears in green.

If the TERR ON ND is selected on, the ND displays the surrounding terrain from the stored database, and the weather radar display will be suppressed.

OPERATION

In standard operation the weather radar is kept in automatic multiscan mode and will always use the most suitable tilt angle for the current flight stage. These optimized settings are a good reference for manual mode.

Creating a mental image of the weather using the weather radar is a complex task where experience is very important. Areas to avoid are large areas with strong rain or smaller areas with tight color bands meaning there is only a small area where the rain increases in density.

Keep in mind that strong fronts hide whatever is behind them. Use the manual tilt and gain to look below the weather in front until ground clutter starts to appear. If the region directly behind the weather remains dark and ground clutter appears on either side it indicates a possible radar shadow.

A quick way to test operation of the weather radar on a clear day is to tilt it down and increase gain with Ground

Clutter Suppression set to off. If you do not see ground returns the system is malfunctioning.
