Q

Will the CVR record after aircraft shutdown?

A

10 minutes (via a self contained battery)

25
What happens when the Right Battery switch is selected?
* CVR Starts recording * BIT Test (Built in Tests) * IRS start aligning * All buses power up
26
What does the Left battery do during APU start?
Provides power to electrical system as right battery disconnects to assist in APU start
27
What buses are shed inflight when done to 1 generator?
Aux buses are shed
28
What notable items will be lost with shedding of Aux buses?
Right window heat Foot Warmers Cabin AC / DC electrical
29
Will batteries auto-disconnect from the system?
If they reach 70C

32
Do the HP and IP systems mix?
No - two independent systems
33
What is the brains of the pressurization system?
IASC Integrated Air System Control
34
What happens when the EMER DEPRESS button is pressed?
Cabin will depressurize to In auto mode: 14,000 @2500 FPM In manual mode: 14,500 @3000 FPM
35
When is the DITCHING MODE available and what does it do?
Below 15,000’ in AUTO mode * Closes outflow valve
36
When is RAM AIR available?
Below 10,000’
37
Why do we wait 2 minutes for the wing ice test?
To test the low temp sensor in the wingtips
38
What bleed system is used for engine/wing ice protection?
High Pressure (HP) - 36 PSI
39
How do the ice protection valves fail?
Wing valves fail closed Engine valves fail open
40
After de-icing - when can we ice systems be turned on?
Engine - no delay Wing - just prior to takeoff
41
Does the APU have a FADEC?
No - an ECU
42
Where does the fuel come from for the APU
Right collector tank
43
Does the APU have fire protection?
Yes - on ground - * will auto shut down * discharge right fire bottle
44
What type of engines do we have?
HTF 7 350 Honeywell Turbo Fan
45
How many FADECs does each engine have?

46
What happens when the RUN SWITCH is selected to ON?
* Boost Pumps activated * FADAC activated
47
When would FADEC activate igniters?
* Engine Start * Stall * Restart * Manually Commanded
48
When does the APR activate?
15 degree split in N2
49
How many QTS are in the HYD systems?
Left: 13 QTS (due to gear actuator volume) Right: 9 QTS
50

53
What is the purpose of the AUX PUMP?
Powers lower PCU if the RIGHT SYSTEM FAILS * note the AUX Pump switch is below #2 HYD switch
54
How does the HYD Fluid stay cooled?
Cooled through fuel/HYD heat exchange Located in each wing fuel tank
55
What is pressure of AUX pump?
Pump cycles on and off to maintain: 2500 to 3350 PI
56
How do you transfer fuel?
High Side Fuel Pump ON to push fuel Cross Feed OPEN * if pumping on ground w/ APU running to right - will need to turn right pump off
