8 secs (3 secs for RAT, 5 secs to pressurize the BLUE hydro system and power the EMER GEN)
*What happens when you push the GEN 1 line pbs?
a. GEN 1 line contactor opens and the white OFF light illuminates
b. AC BUS 1 is powered by GEN 2 thru BUS TIE Contactor
c. GEN 1 continues to power 1 fuel pump in each wing tank

APU
*Which valves will receive a close command when DITCHING pbs is depressed?
Avionics/Inlet and Extract valves
RAM air inlet
Pack Flow Control Valves
Outflow valve (only if in AUTO mode)
*When the mode selector is out of the AUTO position, how do you set a landing elevation?
Manually by selecting the landing elevation via the LDG ELEV dial
*What would cause an amber FAULT light to illuminate in the PACK 1 and/or PACK 2 pb (OOD)?
Overheat – Pack outlet
Overheat - Compressor outlet
Discontinuity – switch position disagreement with pack flow control valve
Note: FAULT light is illuminated when no bleed air is on
*At what cabin differential pressure does the RAM AIR valve open?
1 PSI ^P or less
*What does the FAULT light in the HOT AIR pb?
Duct overheat - Hot air/Trim air valves automatically close
*When performing the PRELIM FLIGHT DECK PREP, what is the minimum battery voltage?
25.5 volts
*During the flight deck prep, what are we looking for on the ELEC panel battery check?
- ECAM ELEC page select
- BATT 1 and 2 OFF then ON
- Check battery current is < 60 amps after 10 secs and continues to decrease
*What does an IDG FAULT light mean?
“HOTLOP”
- High Oil outlet temperature
- Low oil pressure
- Light is inhibited when IDG is disconnected
*How can an IDG be reset?
On the ground with maintenance
*What are the 3x the batteries are connected to the BATT BUS?
- APU start
- Battery charging
- AC BUS 1 and 2 not powered and flying < 100kts
*What will cause a FUEL MODE SEL FAULT light?
Failure of the AUTO mode
Center tank > 350lbs and either main tank < 11,000 lbs
*How is the IDG cooled?
Fuel from the HP fuel pump drawn from the fuel manifold and then returned to its respective outer tank. When full, the outer tank spills into the inner tank.
*What does and amber FAULT light in the FUEL PUMP pb indicate?
Low fuel pressure delivery
*What does the amber boxed ECAM FOB mean?
Unusable fuel
*How many hydraulic pumps are in the GREEN system?
Two = 1 Engine and 1 PTU
*How many hydraulic pumps are in the BLUE system?
Two = 1 RAT and 1 Electric
**How many hydraulic pumps are in the YELLOW system?
Four = 1 Engine, 1 Electric, 1 PTU, 1 Hand pump
*Where are the engine fire loops installed?
- Pylon nacelle
- Engine core
- Fan Section
*What does and amber DISCH light mean?
The fire extinguisher bottle lost its pressure
*What occurs when the TEST pb is pressed on the ENGINE FIRE panel?
7 lights
- 2 Master warn lights flash
- 1 ENG FIRE pb illuminates red
- 2 squib and DISCH lights illuminate
- 1 ECAM Fire warning
- 1 Fire light on ENG panel lights up
*Does the APU fire extinguisher automatically discharge if a fire is detected on the ground?
Yes. APU shuts down and APU fire bottle discharges
*What does the CARGO HEAT HOT AIR amber FAULT light mean?
Duct overheat
*How many fire extinguishers are provided for the cargo compartments?
1 bottle - discharge into either compartment
2 bottles - discharge into either compartment 205 min (ETOPS)
*What does an amber FAULT light mean – BLOWER pbs?
- SMOKE warning is activated
- Computer supply power failure
- Low blower pressure
- Duct overheat
*What’s an AMBER FAULT light mean for EXTRACT pbs?
- SMOKE warning is activated
- Computer supply power failure
- Low extract pressure
*What is the meaning of “USE MANUAL PITCH TRIM”?
Flying in “Direct Law”
*Which hydraulic systems provides pressure to the brakes?
- Normal brakes - Green (go)
- Alternate brakes - Yellow (caution) backed up by the hydraulic accumulator
*What is the active range of the A/THR?
Just above IDLE to CL detent (both engines)
Just above IDLE to MCT detent (OEI)
FAULT light in the APU BLEED pb
APU BLEED LEAK
APU Bleed Valve closes
FAULT ENG 1 or 2 BLEED pb
