After turning Batteries 1 and 2 to "ON" and "AUTO," what three things are we looking
for? - answer Screen 2 illuminates (status page)
Screen 3 illuminates (EICAS)

,IESS is aligning (90 seconds)
* No other screen should be displayed

Under what voltage must a "battery recharge procedure" be accomplished? - answer
22.5

Under what voltage must maintenance be called? - answer 21

Why is it important to wait approximately 30 seconds after energizing the batteries
before running the fire extinguisher panel test? - answer To verify the EICAS has
fully energized and that there are no fire protection/detection fault/fail messages

List all items that are part of the fire extinguisher panel test. How do you know you had
a good test? - answer 6,5,2,2,2
6 overhead lights
- 2 handles
- FWD cargo detect/extinguish button
- AFT cargo detect/extinguish button
- APU emergency stop
- APU Fire extinguishing button
5 EICAS messages
- ENG 1 FIRE
- ENG 2 FIRE
- CRG FWD SMOKE
- CRG AFT SMOKE
- APU FIRE
2 aurals
- Fire bell
- Master warning aural
2 ITT Fire indications
2 master warning lights

NO FAIL EICAS MESSAGE?

What test begins when AC power is applied to the aircraft? How do you know it is
running? How long? What does it check? What interrupts the test? - answer
Electrical PBIT
"FLT CTRL TEST IN PROG" EICAS message
3 minutes
Out-of-tolerance conditions and failures associated with the FCMs, P-ACEs, and SF-
ACEs
1) Any hydraulic pump is running
2) FCM panel switches are cycled
3) AC power supply is interrupted

,What test begins when all three hydraulic systems are pressurized in the order 3A, 1, 2?
How do you it is running? How long does it take to complete? What does it check? What
interrupts this test? - answer Hydraulic PBIT
"FLT CTRL TEST IN PROG" EICAS message
1 minute
Functional test of the flight control actuators (PDUs for SF, PCUs for all other surfaces)
Flight control surface is moved

What are the minimum voltage for Batt 1 and Batt 2 during the safety and power-up
checklist? - answer Batt 1: 22.5
Batt 2: 22.5

If battery voltage is between 22.5-21, batteries can be recharged before takeoff.

If battery voltage is below 21, DO NOT DEPART

What is the AC Power Priority? - answer 1) Onside generator
2) Inside (APU)
3) Outside (GPU, on ground without APU)
4) Cross-side generator

What are the two main components on the DC HOT BAT BUS 1 and 2, that we, as
pilots, care about? - answer PANEL REFUEL, ENGINE 1A FIRE EXTINGUISH,
ENGINE FIRE 1B FIRE EXTENGUISH

What type of circuit breakers does the E175 have? How do I access them? - answer
Electronic and thermal circuit breakers.
Some of the thermal circuit breakers are located physically on the flight deck, and the
other half can only be checked via the MCDU
All of the electronic circuit breakers must be checked via the MCDU (remote)

Briefly explain the purpose of the RAT - answer The RAT, Ram Air Turbine, can
provide backup AC power in the event of total AC loss by turning the kinetic energy of
airflow into AC power

Which bus/buses does the RAT power? - answer AC ESS BUS, DC ESS BUSES
powered through the ESS TRU.

How long does it take before the RAT provides full power to the AC ESS bus? - answer
8 seconds

When will the RAT automatically deploy? - answer Whenever the AC power sources
are not powering the AC buses in flight

What EICAS message would indicate the RAT has not deployed during an electrical
emergency? - answer BATT DISCHARGING

, What is the minimum speed to get the RAT spinning initially? - answer 150 KIAS

What is the minimum speed to keep the RAT powered? - answer 130 KIAS

Is there an altitude restriction for operation of the RAT? - answer No

What items are on the AC STBY BUS? AC ESS BUS? - answer STBY AC BUS:
ENGINE 1 EXCITER 1A
ENGINE 2 EXCITER 2A

AC ESS BUS:
AC FUEL PUMP 2A
ACMP 3A (supplies the elevator, rudder, and ailerons with hydraulic power)
Slat Channel 2
Flap Channel 1

What purpose does an inverter serve? - answer Converts DC to AC power. The AC
STBY BUS is powered when the RAT is deployed through the static inverter. Our DC
batteries can power this since the DC ESS BUSES are being energizing through the
ESS TRU, powered by the RAT, which stops them from discharging.

What purposes do a TRU serve? - answer Convert AC to DC power. Three TRUs
convert 115V AC into 28V DC.

How long can batteries supply essential loads? - answer 10 minutes

What kind and how many batteries does the E175 have? - answer 2 Sealed Lead-
Acid batteries, 24V, 28 Amp hour to power up the airplane and as a backup for the DC
essential electrical system

How are the batteries charged? - answer ANY AC source through the TRUs,
including the AC GPU and the RAT

What is the difference between OFF and DISC on either IDG selector? - answer
OFF: Opens the IDG contactor isolating the IDG from the respective AC bus
DISC: Mechanically disconnects the IDG (must be held in position for one second)

What, operationally, is powered even while the batteries are off? - answer PANEL
REFUEL, ENGINE 1A FIRE EXTINGUISH, ENGINE FIRE 1B FIRE EXTINGUISH

What happens when I pull the ENG fire handle? What happens when I rotate? - answer
Pull: Commands the fuel shutoff, hydraulic shutoff, bleed air shutoff, and bleed air x-
bleed valve to close.
Rotate: Extinguishes fire (rotating counter clockwise will discharge bottle A, rotating
clockwise will discharge bottle B)
