Lights And Switches

Question 1

IR white align light
Steady
Flashing

Answer 1

Steady respective IR is in the alignment process
Flashing respective IR is
-Out of position by more than 1* from last known shut down position (60 nm)
-Aircraft moved during alignment process
-No position after 10 minutes during alignment process
-IR alignment fault during process
-

Question 2

ADR1 2 or 3 fault

Answer 2

Fault in associated air data reference computer
All three to off will give fast slow colored scale on speed tape and altitude will be read from GPS position with last two digits underlined to indicate its inaccuracy.

Question 3

ELAC1 or ELAC 2 fault

Answer 3

ELAC Has faulted
Also fault light for 8 seconds during power up test
Power up test also initiated when a power interruption of greater than 25 milliseconds occurs

Question 4

SEC 1 2 or 3 fault

Answer 4

Associated SEC Has faulted . Fault light extinguishes when SEC in off position

Question 5

ELAC FUNCTIONS

Answer 5

Normal pitch and roll
Alternate pitch 
Direct pitch and  roll
Abnormal attitude
Aileron drop
Acquisition of autopilot orders
Switching off then on resets the computer

Question 6

IR1 2 or 3 Fault
Steady
Flashing

Answer 6

Steady respective IR is lost

Flashing - heading and attitude may be recovered in ATT mode

Question 7

FAC 1 or 2 Fault

Answer 7

FAC ‘s
-Flight envelope, speed tape fly tail
-Normal roll ( coordinating turns and dampening Dutch roll)
-Rudder trim
-Rudder travel limit
-Alternate Yaw
Fault simply a fault in the FAC. Fault light goes off when FAC is turned off

Question 8

Gen line 1
Off or
Smoke

Answer 8

Blower and extract will have fault lights as well shuts down .
gen 1 now has only 1 fuel pump from each fuel tank on it
In OFF POSITION IT DISCONNECTS GEN 1 from the rest of the electrical system except for one fuel pump in each wing. The ACBUS 1 is now powered by GEN 2
“SMOKE” in Amber indicates smoke detected in the avionics compartment and will remain on regardless of position until smoke is no longer detected

Question 9

RAT & EMERGENCY GEN fault light

Answer 9

Illuminates red fault when loss of ACBUS 1and 2 occurs and is not powered by the emergency generators.
Gives four screens pfd1 nd1 mcdu1 engine warning display fault displays momentarily while rat is deploying as well. Only fault light that is red! PFDs and MCDU only until emergency generator connects power then 4 screens

Question 10

RAT & EMER GEN Manual on (guarded switch)

Answer 10

Only 2 screens powered captain pfd and captain mcdu by battery until ram air turbine generates power (approx 8 secs) then 4 screens are powered PFDs ND EWD and MCDU. All on captain side BELOW 100 knots only have 2 screens lose DC ess bus
Opens blue hyd valve and also priority valve to emergency generator(unlike the hyd deploy button that is similar that gives no electric output) because that one only opens the hyd valve to blue system
On hot battery bus
Below 50kts screens drop off only have outflow valve and radios (vhf1) and APU fire protection

Question 11

Engine fire push button

21212

Answer 11

Detection in both loops or one defect and other detects or both break within 5 secs of each other (21212) when power removed from FADEC it shuts off IDG return fuel .

(2) -Cancels repetitive chime
- Halon bottle squibs armed
(1) -Hyd Fire wall shut off valve closes
(2) -Fuel low pressure valve closed
- Idg return fuel shut off thru FADEC power supply removal
(1) -Corresponding generator (gen 2 ) is deactivated
(2) -Pack 2 flow valve is closed
- Engine 2 bleed valve closed

Question 12

APU FIRE Button pushed does

20212

Answer 12

2,0,2,1,2
Cancels repetitive chime
Arms the squib and illuminates the light
APU LP fuel valve closes
APU fuel pump shuts off
APU generator shuts down
APU bleed air valve closes
Crossbleed air valve closes

Question 13

Engine 1 hyd pump

Answer 13

Low air pressure in reservoir due to LO precharge on reservoir that prevents bubbling
(4)5345
Reservoir low level
Reservoir low air pressure
Reservoir overheat
Pump low pressure

Question 14

Blue electric hyd pump

Answer 14

On after engine start
4(5)345
(2 separate overheats possible)
Fault light for
-Low air pressure in reservoir due to LO precharge on reservoir that prevents bubbling
-Pump overheat
-Reservoir low level
-Reservoir low air pressure
-Reservoir overheat
-Pump low pressure

Question 15

PTU Hyd button

Answer 15

Can be looked at as confirmation light for reservoir problems in eng 1/2hyd pumps. If one of those fault lights on and the PTU fault comes on as well, it is a res problem
Also PTU is inhibited during takeoff 2 minutes or below 1500 AGL
45(3)45
Green or yellow hyd reservoir low level
Green or yellow reservoir low air pressure
Green or yellow reservoir overheat

Question 16

Yellow hyd electric pump

Answer 16

May be used to recharge brake accumulator. Warning it will also press. The green system. Tell ground personnel first. Nose wheel steering will be energized and may snap over a tow bar
This one can fault also for PUMP  overheat (electric)
4534(5)
-Pump overheat
-Reservoir low level
-Reservoir low air pressure
-Reservoir overheat
-Pump low pressure

Question 17

Center fuel pumps

Answer 17

If fuel in center tank is >550lbs and fuel in at least one wing is
