What is the ADIRS?
Air Data and Inertial Reference System
What type of information does the Air Data Reference System provide?
Altitude, airspeed, over speed warnings, temperature, angle of
attack, mach.
What type of information does the IR provide?
Attitude, Flight Path Vector (FPV), track, heading, acceleration, angular
rates, groundspeed and aircraft position.
If there was an IR1 FAULT, what should be done with the switching panel to display backup data appropriately?
ATT/HDG to Capt 3
If there was an ADR1 FAULT, what should be done with the switching panel to display backup data appropriately?
AIR DATA to Capt 3
Explain the ADIRS Power-up and Initialization.
Switch from OFF to NAV
ON BAT
White ALIGN light illuminates for the duration of alignment (only on A319;
502-534)
In A319; 535,536, A320s, and A321s, the E/WD memo section displays
“IRS IN ALIGN” during alignment and replaces the ALIGN lights on the
overhead panel.
What are some indications of an ADIR having reverted to battery power on the ground?
An external horn sounds
The ON BAT light comes on
An ADIRU & AVNCS light illuminates in amber on the external power panel.
What is the significance of a steady FAULT light on the IR?
IR has failed and cannot be recovered
What is the significance of a flashing FAULT light on the IR?
Navigation function is lost. Attitude and Heading may be recovered in ATT mode.
Describe what would happen if an ADR was selected OFF
The pilot would lose barometric altitude, airspeed, mach, angle of attack,
temperature and over speed warnings from that one ADR.
The ECAM would instruct the pilot to select the AIR DATA SWTG to CAPT
3 or F/O 3 as appropriate.
At that point the affected pilot’s side would return to normal.
What functions are lost when an IR is turned OFF?
Older model: Lose IR part. Newer panel: Can turn off only the IR and ADR info stays
When would a pilot perform a complete alignment?
- Before the first flight of the day
- When there is a crew change
- When the departure airport is located between latitudes 2o north and 2o south
- If GPS is not available and NAVAID coverage is poor on the expected route
- If GPS is not available and the expected flight time is more than 3 hours
When would a pilot perform a fast alignment?
More than 5nm difference
What could cause the flashing white ALIGN light to illuminate on the ground?
- PPOS not entered within 10m of alignment or 3m of fast alignment
- Large difference LAT/LONG between shutdown position and entered position.
- Aircraft movement during alignment.
What does the illumination APU MASTER SW FAULT indicate?
Automatic APU shutdown has occurred
What is the significance of the APU AVAIL light illuminating?
APU is running above 99.5 % or 2 seconds after N speed reaching 95%. In practical terms it is ready to accept and support ELEC and/or AIR load.
What condition in the APU system would cause an external horn to sound on the ground?
APU fire
With the APU green AVAIL light ON and the EXT PWR green AVAIL light on, which system is powering the aircraft?
2 Avails = APU powering the aircraft
If possible, how would the APU be used if it has already started the cool-down cycle?
Pressing the APU MASTER SW pushbutton
When running the securing checklist why is it important to wait 2 minutes after the APU avail light goes out before switching off the batteries?
Switching the batteries off before the APU flap is closed may cause smoke in the cabin during the next flight.
If one generator fails, what is the maximum altitude that you can start the APU?
FL 410
If your aircraft is in an emergency electrical configuration, what is the maximum altitude to start the APU?
FL 250
How is the landing field elevation entered into the pressurization system in automatic, semi-automatic and manual modes?
- Automatic = FMGC (LDG ELEV must be in AUTO)
• Semi-automatic = by LDG ELEV selector button
• Manual = By selecting the MODE SEL to MAN and then using the MAN V/S CTL toggle switch
What does selecting the DITCHING pushbutton ON accomplish?
Closes all openings below the waterline
Note: If you lose both cabin pressure systems 1 + 2, you have to manually close the outflow valve.
When would a pilot push the ditching pushbutton?
- When ditching
• When directed by the deicing checklist
How many controllers are in the pressurization system?
Two, only one is used at a time and they swap roles after each landing
How can a pilot manually switch controllers?
Switch MODE SEL to MAN for 10 seconds, then back to AUTO
What does an amber FAULT light in the MODE SEL pushbutton indicate? [Pressure]
Both automatic pressure controllers are faulty
What protects the airframe from excessive cabin differential pressure?
Two pressure relief valves
If PACK FLOW is selected to LO, NORM or HIGH and only the APU is providing BLEED AIR or one pack is selected OFF, what will the packs provide?
HIGH flow rate, since the flow rate function is automatic.
If the HOT AIR valve faults, what will happen to the temperature control system?
All trim air valves close and PACK 1 controls the cockpit temperature to the selected value. PACK 2 controls the cabin to the averages selected by the FWD and AFT CABIN temperature selector knobs.
How are the PACKS controlled and operated?
Electrically controlled and pneumatically operated.
What are some potential causes for a PACK FAULT light?
- Valve position disagrees with selected
• Compressor outlet overheat
• Pack outlet overheat
What are some potential causes for ENG BLEED FAULT light?
- Bleed overpressure
• Bleed overheat
• Wing or engine leak on the related side
• Bleed valve NOT closed during engine start
• Bleed valve NOT closed with the APU BLEED ON
What is the logic for the X-BLEED rotary selector?
- SHUT = the valve is closed.
• AUTO = open if the APU bleed valve is open; closed if APU bleed valve is
closed or there is a wing, pylon or APU leak (except during an engine start).
• OPEN = the valve is open.
What does APU BLEED FAULT illumination indicate?
APU bleed leak.
What does selecting the RAM AIR pushbutton accomplish?
• Ram air inlet opens if the differential pressure is less than 1 PSI.
What is the RAM AIR pushbutton used for?
- Smoke/fumes removal in cabin
• Ventilation of cabin with a dual pack failure
How is the Bleed leak detection different on CEO and NEO aircraft?
If a Bleed Air Monitoring Computer (BMC) fails on NEO airplane, over temperature protection is lost on the affected side. Has no effect on CEO.
When should you select LO pack flow?
- On the 319, when the number of passengers is below 138.
• On the 320, when the number of passengers is below 141.
• On the 321, select ON ECON FLOW when the number of passengers is below 168.
Generally, what is the total fuel capacity?
42,000 lbs (41,285)
Why is it possible for there to be a value higher than 42,000 lbs indicated on the ECAM FOB?
The fuel can expand by 2% without venting overboard
How many fuel pumps are on the aircraft and where are they located?
- There are seven total fuel pumps: two center tank pumps, four wing tank pumps, (two in each wing) and one APU fuel pump. On some aircraft, the center tank pumps are jet pumps, which transfer fuel from the center tank into the wing tanks.
• The APU pump is used when fuel feed pressure is low (due to loss of tank pumps or loss of normal AC electrical supply)
Explain the flow of fuel from before engine start to climb (assume full tanks).
- At engine start the fuel is fed from the wing tanks
• After an engine is started, the center tank pumps turn on and continue to run for 2 minutes.
• If slats are selected within those 2 minutes, the center tank pumps will continue to run until the time has elapsed, then they will stop.
• If the slats are extended at any other time, the center pumps will shut off.
• At takeoff, the engines feed fuel from their respective wing tanks.
• When slats are retracted to zero, the fuel is fed from the center tank.
• When the center tank runs low, the pumps continue to run for 5 min.
What is the difference between CTR TK Pump on a A319 and some older A320’s (601 – 628) versus CTR TK XFR (transfer) on the A321 and newer A320’s (629 – 656, 690 – 696, 901 – 915)?
CTR TK Pumps are identical to the main tank fuel pumps. The CTR TK XFR are jet pumps that transfer center tank fuel to the main L (R) pumps.
What does a fault light in one of the L(R) TK PUMPS pushbuttons indicate?
Low delivery pressure
What does a fault light in the MODE selector indicate? [Fuel]
- Failure of the AUTO mode
• Center tank has more than 550 lbs and either wing tank has less than 11,000 lbs
How would a pilot know that fueling is in progress?
REFUELG message appears on the ECAM. This does not mean the fuel is entering the tanks, merely that the refueling door is open.
Describe IDG cooling and how it relates to the FADEC.
Some of the fuel supplied to each engine goes from the high-pressure fuel line in that engine, through the integrated drive generator (IDG) heat exchanger (where it absorbs heat), to the fuel return valve, and back to either the wing tank or outer tank, depending on the aircraft.
• This operation ensures IDG cooling when the oil temperature is high or when at low engine power.
• The FADEC controls the fuel return depending on the temperature of the IDG – the higher the temperature, the higher the flow.
What happens if returned IDG cooling fuel fills the wing tanks while the center tanks are feeding?
The center tank pumps will cut off until the wing tank quantity is reduced by 1,100 lbs in the inner tanks
What is the approximate fuel capacity of each outer fuel tank, when installed?
Approximately 1,500 lbs
When do the wing outer tanks drain into the inner tanks?
When the inner tank quantity reaches approximately 1,650 lbs
If only one inner tank reaches 1,650 lbs, what happens to the other transfer valve?
All four transfer valves open
Once opened to transfer fuel, how are the fuel transfer valves closed?
Automatically at the next refueling operation as long as there is AC power on the aircraft
Describe the layout of the fuel tanks.
- The fuel tank layout depends on the specific aircraft.
• Fuel is stored in a center tank and wing tanks:- On 319s and 320s, the wing tanks are divided into inner tanks, outer tanks, and vent tanks. - On 321s, the wing tanks are not divided into inner and outer tanks, but still have vent tanks.
What are the three HYD systems called?
GREEN, BLUE and YELLOW Systems
How is each hydraulic system normally powered?
- GREEN – engine driven
• BLUE – electrically driven
• YELLOW – engine or electrically driven
When does the BLUE pump normally operate?
After the first engine is started
If the BLUE system lost pressure, how would pressure be restored?
The RAT must be deployed. It does not deploy automatically upon BLUE system loss of pressure, so if needed, it must be manually deployed with the RAT MAN ON pushbutton.
What can be done to correct low ACUM PRESS indication?
On the ground, coordinate with ground personnel and turn on the YELLOW ELEC pump
With no HYD system power, how can the FWD CARGO door be opened?
By using a hand pump
What causes the PTU to operate in if in AUTO?
Differential pressure of 500 psi between GREEN and YELLOW systems
When is the PTU inhibited?
- On the ground with ENG MASTER levers split and either the nose wheel steering disconnected or the parking brake ON
• For 40 seconds after cargo door is operated
What are some users of the GREEN system?
- Landing gear
• Normal brakes
• Slats and flaps
• ENG 1 thrust reverser
What are some users of the BLUE system?
- Emergency generator
• Slats
What are some users of the YELLOW system?
- Flaps
• Nose wheel steering
• Alternate brakes
What do the priority valves do in the HYD systems?
Removes hydraulic power from the heavy users and protects the flight controls.
What would cause a FAULT light in the ENG 1 pump?
- Pump low pressure
• Over temp in reservoir
• Low air pressure in reservoir
• Low quantity
If the FAULT light illuminates in the ENG 1 pump, what would identify the specific reason for the FAULT?
ECAM will display the reason
What must the flight crew be aware of when doing a Manual Start on the ground or an Auto Start in the Air?
The crew must abort the start if something goes wrong
What are the primary differences between a manual and a normal automatic start?
- The FADEC provides full monitoring during a manual start and will provide appropriate ECAM cautions and procedures to follow in the event of a start fault
• Automatic start interruption and auto-crank are not available
With the ENG MODE selector in IGN/START what occurs when the ENG MAN START pushbutton is pressed?
- The start valve opens
• Both pack flow control valves close
What is the primary difference between the IAE V2500 and PW1100G engine?
The NEO PW1100G engine includes a Fan Drive Gear System (FDGS) which allows the low pressure turbine to operate at higher rotational speeds for peak efficiency while the engine’s fan can operate at lower speeds for optimum propulsion efficiency and lower noise levels.
When would a First Officer manually abort an AUTOMATIC start on the ground and what COM procedure would you apply after selecting the master switch to off?
- The ground crew reports a tail pipe fire, accomplish the COM Abnormal/Emergency Procedures “Engine Tailpipe Fire” procedure.
• In the case of electrical power supply interrupted during the start sequence (indicated by loss of the ECAM DUs), COM supplemental procedure Engine Ventilation (Dry Cranking)
What is the approximate time the engine will dry crank during an Automatic engine start?
- IAE V2500 = Approximately 30 Seconds
• PW1100G = Approximately 2 Minutes
