Systems Flashcards
From James' Audio
When does the ON BAT light come on?
- Comes on as self test
- one or more IR are on BAT (external horn also sounds)
If they are being powered by the batteries, how long do you have to recover the electrical system?
5 Minutes
What happens after the 5 minutes?
A couple will drop, the ones the CA is not using, typically IR 2 and 3
What happens if the CA is using IR 3 or he selected #3 on the ATT/HDG panel?
IR 1 and 2 will drop instead
What happens when you have a steady FAULT light on the IR panel?
The gyro has tumbled and is no longer good for anything (ATT, HDG, or NAV)
What happened if IR is flashing FAULT?
- ATT and HDG may be recovered using ATT mode
- You would have to select out of NAV and put it in ATT and give it a position
What does it mean if all 3 ALIGN lights are white?
The system is in the alignment process which takes 10 minutes
What does it mean if all 3 ALIGN lights are flashing? (3 things)
a. There hasn’t been a position entered in the last 10 minutes
b. Bad position – 1˚ or 60 miles difference between shutdown and entered
c. There is a FAULT (AC was significantly moved during the alignment process)
What does the ADR FAULT light indicate?
Pitot static system on that side has been lost
How do you fix that?
Put the CA or FO on AIR DATA #3, the backup
What is ELAC?
Elevator Aileron Computer
What’s the primary computer for the ailerons?
ELAC 1
What’s the primary computer for the elevator?
ELAC 2
What is SEC?
Spoiler Elevator Computer
What is the primary computer job for the SEC?
Spoilers
What can the SEC do in backup mode?
Can control the elevators
What is FAC?
Flight Augmentation Computers
What are the primary jobs of the FAC? (RFLW)
- Rudder (coordination, damping, trim, travel limit, alternate law)
- flight envelope protection (PFD speed tape, alpha floor protection)
- low energy warning
- wind shear detection
What happens when you lift the guard and press the EVAC button?
Sends signal to cabin to notify of evacuation situation
What will this sound like?
High frequency tone and beeping
How do you cancel the tone?
Hit Evac Horn Shutoff
What does SMOKE mean under the GEN 1 Line button?
Smoke in avionics compartment
Are there any confirmation lights anywhere else?
Ventilation panel, the BLOWER and EXTRACT will both show FAULT
What happens when you push the GEN 1 line to OFF?
- Gen 1 is disconnected from AC Bus 1 (Gen 2 then powers AC Bus 1)
- Powers one fuel pump in each wing tank
What does the RED FAULT light mean on the RAT and EMER GEN?
Emergency Generator is not supplying power, but should be (AC1 and AC2 are not powered)
What will you do if you see that?
Lift the guard and push the button which Manually extends the RAT and connects Emergency Generator to electrical system
What does an amber FAULT light on the TERR pb indicate?
- The terrain database has been lost
- EGPWS failed
What should you do then?
- Turn the system OFF, inhibiting the terrain function
- Will still get basic modes on the GPWS (TOO LOW FLAPS/GEAR)
What happens with SYS FAULT?
Lost all of the GPWS modes including the enhanced GPWS
What are G/S and FLAP modes for?
Abnormal conditions to where you will turn that mode off
When will you use LDG FLAP 3 mode?
When planning for a FLAP 3 landing
What do you need to along with selecting that button?
MCDU performance page and select CONFIG 3
When is the CVR first powered?
When you first apply external power to the aircraft for the first 5 minutes and then it turns off
When will it start recording automatically?
At engine start
When you do the CVR test and it does not make the tone what is most likely the cause?
The parking brake is OFF
What does the white SYS ON light indicate on the PASSENGER pb?
Signal to open mask doors has been activated Remains on until TMR RESET pb pushed on Mx Panel
At what altitude do the pax oxygen masks drop?
when cabin altitude exceeds 14,000’
What allows the oxygen bottle to connect to the manifold and supply oxygen to the cockpit masks?
CREW SUPPLY pb on overhead panel
What is happening when you press the APU MASTER SW? (E-F-F-F-E)
- ECB (electronic control box) power and self test
- Flap opens, APU inlet
- Fuel pump turns on
- Fuel Valve Opens
- ECAM, APU page comes up
What does the GREEN AVAIL light mean on the START button?
the APU is on speed and ready for use
N > 99.5%
N > 95% for 2 seconds
What does the amber FAULT indicate on the MASTER SW pb?
the last shutdown was abnormal or auto shutdown
When will the APU auto-shutdown for fire?
will only shutdown on the ground, NOT in flight
What part of the wings are anti-iced?
the 3 outboard slats
What is the default position for the wing anti-ice valve if it were to lose the electrical signal?
CLOSED
What does an amber FAULT light indicate on the WING anti-ice pb? (LVV)
- low air pressure
- valve disagreement
- valve in transit
What part of the engines are heated?
engine nacelle leading edge
What is the default position for the ENG anti-ice valve if it were to lose the electrical signal?
OPEN
What does an amber FAULT light indicate on the ENG anti-ice pbs?
- valve disagreement
- valve in transit
When is the TAT probe heated?
automatically when airborne
What is heated when AUTO is selected on PROBE/WINDOW HEAT pb? and when are those items heated?
- probes and windows are heated in flight and on the the ground WHEN one engine is running, except TAT probe
When are the DRAIN MASTS powered?
whenever the is ext power or another power source on the AC
How many automatic controllers does the cabin pressurization system have?
2
How often do they changeover?
70 seconds after each landing or in the event of a system failure
When the LDG ELEV knob is in AUTO, where does it pull its info?
being pulled from the FMGS to control the pressurization schedule
When should you NOT use the AUTO function for LDG ELEV?
- dest airport is not in the database
- database is incorrect
- ECAM or guidance computer would give directions to do so
What are you doing when you take the LDG ELEV switch out of AUTO?
