If power is lost to either AC or DC EMER buses, Battery will power these buses.
Automatically tested on ground with both engines shut down when switch moved from OFF to ARM. Indications: ON light illuminates and EMER PWR TEST alert displays.
Must be OFF if crew leaves a/c with EXT PWR.
which buses are powered on EMER PWR and how long the battery can provide
power
approximately 60 minutes: Battery direct bus DC transfer bus Emergency AC bus (through emergency inverter) Emergency DC bus
Explain the function of the L/R BUS TIE Switches
Open – Respective generator cannot power the
tie bus. Can also be used to reset a bus tie
lockout on the ground
AUTO – Generator bus to tie bus connection is
controlled automatically to meet aircraft power
requirements
Recall the function of the DC BUS TIE Switch
OPEN - Opens all three DC bus tie relays
AUTO - DC bus tie relays are automatically controlled to
ensure all DC buses are powered
Recall the function of the L/R GEN Switches
RESET – Resets the generator
OFF – Disconnects the generator from the respective bus
ON – Allows an operating generator to supply power to its respective bus
Recall the function of the APU Power Switch
RESET – Resets the generator
OFF – Disconnects the APU generator from the tie bus
ON – Allows an operating APU generator to supply power to the tie bus
Recall the function of the EXT Power Switch
OFF – Disconnects EXT PWR from the tie bus
ON – Connects EXT PWR to the tie bus
Recall the function of the GND SERVICE ELEC PWR Switch
OFF - Neutral position for ground service power
ON - Connects external power to the AC ground service bus and powers the
DC ground service bus. EXT power switch is OFF
Recall features of the No Break Power Transfer (NBPT)
Normally, all electrical power source transfers will occur without power interruption
Momentary breaks in power supply, however, may occur during the transfer of power
from the APU to an external source OR if a supplying generator experiences an
unexpected power loss (due to a flameout or unexpected shutdown, etc)
Rated thrust of BR715 engine
21,000 lbs
Engine starter duty cycle limits
Three start attempts, with a maximum of 3 minutes duration each
15 seconds is required between start attempts
Allow 15 minutes of starter cooling before further start attempts are made
Recall the requirements for a ground, engine AUTO START
IGNITION Switch – AUTO
ENG START Switch—Pulled
FUEL Switch – ON
During an auto-start, the EEC controls all fuel metering and ignition to the respective
engine once the ENG START Switch is pulled and the FUEL Switch selected ON. The
auto-start includes an automatic 30 second engine motoring delay before fuel is
introduced
Auto-Start also includes a TGT protection threshold and will not allow fuel introduction
unless the respective TGT is below 150ºC
Recall reasons for an Auto Abort during a ground engine Auto Start
- Hung Start
- Starter duty timer is exceeded (3 minutes)
- Hot Start (or impending hot start) - 700ºC
- Fuel On condition not satisfied (TGT is above 150ºC)
- Loss of valid N2 input
- Certain failures of both channels of EEC
Are inflight starts AUTO or MANUAL?
Manual only.
AUTO ABORT start protections provided by the EEC are not available
during in-flight starts – ALL in-flight starts are MANUAL starts
Recall the required engine warm up and cool down times
WARM UP
- following engine shut down of 2 hrs or less = NONE
- following engine shut down > 2 hrs = 3 min
COOL DOWN
- 3 minutes and verify “ENGINE COOL” alert message on EAD

DUAL ignition: Combustor instability Significant water ingestion Significant ice ingestion Flameout
SINGLE ignition:
-after either ENG ANTI ICE selected on (for 60 seconds)
how to select EMERGENCY thrust
by pushing thrust levers through the mechanical gate
(at gate is MAX thrust, beyond is EMER)
EPR will still be displayed, however, thrust management will be based on N1
ATS will disconnect automatically and the QRH should be referenced for reengagement
REV thrust indications
U/L = not stowed
REV (green) = 90% deployed
REV (red) = uncommanded deployment; EEC reduces thrust to IDLE on affected engine
how to select EMERGENCY REVERSE power
Emergency reverse thrust is obtained by pulling the reverse thrust
levers through a mechanical gate (and holding them in position)
When selected, engine damage can occur, and a maintenance
inspection will be required
Recall the APU starter motor duty cycle
The APU starter duty cycle is limited to three consecutive start attempts
Wait 30 minutes prior to further start attempts
Recall the normal and back-up fuel supply for the APU
APU fuel is normally supplied from the right main tank
Using crossfeed, fuel can be supplied from the left tank
When center tank pumps are used to supply fuel to the APU (both pumps ON), a right
main tank fuel boost pump should also be operating
When center tank fuel value is less than 800 pounds, using center tank pumps can
force air into the APU fuel line and cause APU flameout or prevent APU start
Recall that an APU start incorporates an automatic delay
APU starts automatically delay approximately 40 seconds to allow the APU inlet door
to open
How long is APU bleed air inhibited after start?
2 minutes
How to verify APU shutdown cycle is complete?
When APU info block disappears from SD ENG display.
Takes approx 1 minute, indicates inlet door is closed.
Recall considerations for shutting down the APU both with and without External Power
available
NO external power, the BATT switch and EMER PWR selector must remain on until
APU shutdown is complete
WITH external power connected, the EXT power switch or the GROUND SERVICE ELEC
PWR switch must remain ON until APU shutdown is complete
Recall the APU continues to run for approximately 17 seconds while a No Power Break
Transfer is performed
This delay is bypassed when the flight deck APU FIRE CONT toggle switch is moved
to the OFF & AGENT ARM position OR when the exterior ground APU toggle switch
is moved to the SHUT OFF position
NOTE: It is also bypassed if an APU fire is detected
Recall the automatic shutdown features of the APU for both ground and in-flight faults
On the ground, when conditions are present that could damage the APU, the APU
automatically shuts down and the amber APU AUTO SHUTDOWN alert is displayed
In-flight, the APU only automatically shuts down for an APU OVERSPEED or an APU
COMPARTMENT FIRE. If an APU FAULT condition occurs in-flight, the APU
automatically shuts down 10 minutes after landing, unless shut down sooner by the
pilot
Recall important considerations if FIRE WARNING test is conducted using BATTERY
POWER only
All indications will be the same as with “External Power Available” EXCEPT
the First Officer’s MASTER WARNING light will not illuminate and the cyan
PODS TEST PASS alert message on the EAD will not be displayed
NOTE: After APU is started and all busses are powered, the Fire Warning test must
be re-accomplished to confirm all correct indications
Recall indications of an ENGINE FIRE

“Land at Nearest Suitable Airport” – Displayed on CONSEQUENCE Page
DISCH CARGO AGENT – Displayed on EAD and AIR SD
AIR SD will display RED triangles
AFT/FWD CARGO SMOKE AGENT DISCH switchlight will flash “PUSH”
Approximately one minute after the first bottle has been discharged, the illuminated
amber AFT/FWD CARGO SMOKE AGENT DISCH “PUSH” switchlight will extinguish
and be replaced by an amber “LOW” light indicating the first Halon bottle has
discharged. A CARGO AGENT 1 LO alert will also be displayed on the EAD
Approximately six minutes later, similar alerts will direct the crew to discharge the
second Halon bottle into the appropriate cargo compartment. The second bottle,
however, discharges at a much slower rate and the CARGO AGENT 2 LO alert will be
delayed for about 2 hours
The red triangles displayed on the AIR synoptic are cargo smoke detectors
Recall cockpit indications of a LAVATORY FIRE
MASTER CAUTION lights illuminate
LAVATORY SMOKE alert on EAD
HI-LO chime on PA
Recall the operation of the Engines/APU LOOPS switches on the AFT Overhead Panel
The fire detection system consists of two independent, heat-sensitive detector loops
located in each engine and the APU. Each loop provides both fire and overheat
detection
BOTH (Normal position) – minimizes false fire warnings since both loops have to
detect fire or overheat condition before activating a fire warning
A/B - Used for dispatch or continued flight with an inoperative loop. In this condition, a
fire warning will occur if the selected loop detects a fire or overheat condition
Recall features of the Engine Fire Extinguishing Controls and Indicators
ENG FIRE Handle:
Light Illuminated – Associated engine fire is detected or test in progress
Pull (Fully Extended) – Shuts off associated engine FUEL and HYDRAULIC shutoff
valves, trips GENERATOR off and silence AURAL/VOCAL warnings
Rotate (After pulling) – Discharges respective agent into the engine
How many fire bottles for engine and APU fire system?
2 fire bottles with separate discharges for each engine and APU.
How is a cargo fire dectected?
2 cargo smoke detectors alarm if system is in NORM. (ANY 2 detectors)
A single detector can trigger alarm if system is in SINGLE.
How long can cargo fire system suppress fire?
80 minutes
How is the rudder powered?
Normally - Right Hydraulic system
Manual (RUDDER HYD CONT off) - rudder pedals move control tab and aerodynamic forces move rudder
How does the rudder limiting system work?
Primary - primary rudder limiter protects the empennage from excessive loads by
restricting rudder travel as airspeed increases. It is a mechanical system operated by
ram air pressure from a pitot tube on the leading edge of the vertical stabilizer
A second rudder restricting system provides rudder limiting in the event the primary
system fails. The system has two positions, restricted and unrestricted, and also
operates as a function of airspeed
Will speedbrakes retract if throttles are advanced?
If the throttles are advanced to high thrust while the speed brakes are extended,
the speed brake handle remains in position, but the speed brakes automatically
retract – confirmation can be seen on the CONFIGURATION SD
Selectable Flap settings
UP - 0 - 13 - 18 - 25 - 40
Where is slat / flap position displayed?
On the configuration SD and on the PFD (below airspeed)
Slats powered by?
Both hydraulic systems, but either can fully operate
Recall the difference between the primary and alternate stabilizer trim systems
Horizontal stabilizer trim is controlled by the primary
trim switches, the alternate trim switches, or the
autopilot (auto pilot using alternate trim system)
The primary trim switches are on the control wheel
and used for manual stabilizer trimming at a faster rate
Stabilizer trim switch on pedestal
OFF
Normal
Normal - OFF light is extinguished and primary stabilizer trim is enabled
OFF – (switch is pushed) amber OFF illuminates and electrical power to the brake
is removed, setting the brake to prevent stabilizer movement
How are elevators controlled?
The elevators are aerodynamically positioned by control tabs, which are
mechanically connected to the control columns
A variable load feel mechanism simulates aerodynamic forces and returns the
control columns to an artificial center position when they are released
How many tabs on the elevators?
2 tabs per elevator
Control Tabs: Operated by the control columns, which then aerodynamically
position the elevators
Geared Tabs: As each elevator is moved, geared tabs are deflected, providing
aerodynamic assistance in moving elevators
A total of four tabs aerodynamically position the elevators
Recall the function of the elevator augmentation system
The elevator has two hydraulic boost cylinders that augment elevator control during
a deep stall recovery, providing additional nose down capability
The system is powered by the left hydraulic system with an accumulator backup in
the event system pressure is lost.
When the elevator augmentation system is activated by pushing the control
columns full forward, the elevators move to full deflection
How are spoilers powered?
3 uses?
Electrically controlled by SECU, hydraulically powered.
- Roll augmentation
- Speed brakes
- decrease lift/increase drag for landing or rejected t/o `
Aileron control?
Ailerons are aerodynamically positioned by control tabs mechanically connected to
the control wheels
Aerodynamic forces on the control tabs position the ailerons
For greater roll control (with more than 5 degrees of control wheel input) the flight
spoilers extend a proportionate amount on the downward moving wing
Recall how pitch control is maintained if either control column jams
An override mechanism, installed on the torque tube connecting the two control
columns, allows each column to operate independently, in the pitch axis, should
either side jam
A substantial amount of force must be applied to the operable, free column, for the
mechanical disconnect to occur
Once disconnected, maintenance is required
Recall how roll control is maintained if either control wheel jams
The aircraft control wheels are linked together by a torque tube and an override
mechanism
In the event one control wheel or control tab cable system becomes jammed, roll
control is still possible with the other control tab by overriding the jammed component
Recall how ground spoilers are auto-deployed for a rejected takeoff or on landing
When armed, the spoilers operate automatically to increase braking during a rejected takeoff
or on landing
Selecting reverse thrust deploys the spoilers for a rejected takeoff
When landing, main wheel spin-up OR a ground shift signal from the nose gear
deploys the spoilers
How can stick pusher be inhibited?
Stick pusher PUSH TO INHIB switchlight
Manually override with aft pressure on control column. (temporary override)
Recall the function of the two aircraft Versatile Integrated Avionics units (VIAs)
Two VIAs provide the following functions: data display, flight management computing,
central aural warning, master warning/caution light activation, and flight data acquisition
Normally VIA-1 provides data for the DUs 1 – 3 and VIA-2 provides data for the DUs 4 - 6
In case of failure, either VIA unit will automatically provide data for all DUs
Recall the function of the two aircraft Versatile Integrated Avionics units (VIAs)
Two VIAs provide the following functions: data display, flight management computing,
central aural warning, master warning/caution light activation, and flight data acquisition
Normally VIA-1 provides data for the DUs 1 – 3 and VIA-2 provides data for the DUs 4 - 6
In case of failure, either VIA unit will automatically provide data for all DUs
When will flight director automatically display?

IRS Flashing NAV OFF Light
During alignment, ADIRU does not receive present
position initialization within 5 to 10 minutes of turn on
Present position entry fails the comparison test with
either the stored or calculated present position
Norm and backup power for ADIRUs? (IRS)
ADIRU-1 is powered by the EMER AC bus and backed up by the aircraft battery if
normal AC power is lost
ADIRU-2 is powered by the R AC bus and backed up by an independent battery for
a minimum of 30 minutes if normal AC power is lost (retains heading, attitude and
position)
When is FDR on and how many hours of data does it record?
Records 25 hours of flight operation
Operative when aircraft parking brake is released and either fuel switch is on
How are DMEs and VORs tuned?
Normally auto tuned, but can be manually tuned on the MCDU NAV RAD page
FMS Speed consideration at 12,000’ in descent?
During descent, at or below 12,000 feet, FMS speed edits ABOVE 245 KIAS will not
be honored due to an FMS preloaded 245 KIAS/10,000 restriction
Over ride to meet a higher speed restriction (ex: 11,000 and 280kias) by using speed select passing 12,000.
Recall when FMS Speed and PROF will auto-engage if PROF is selected on the ground
prior to takeoff
400 AGL
Recall when FMS NAV will auto-engage if NAV is selected on the ground prior to
takeoff
100 AGL
Before takeoff, which climb thrust setting to select?
When TOGW is greater than 100,000 lbs, select CLB1
When TOGW 100,000 lbs or less, select CLB2
When the sustained climb rate decreases to less than
1,000 fpm, select the next higher climb thrust setting
(CLB1 or CLB); i.e., CLB2, then CLB1, then CLB
Recall an important FMS speed consideration reaching 12,000 MSL in descent
During descent, at or below 12,000 feet, FMS speed edits ABOVE 245 KIAS will not
be honored due to an FMS preloaded 245 KIAS/10,000 restriction
pilot should take speed control away from “FMS SPD”
by preselecting 280 KIAS in the IAS window and pulling the IAS knob (Speed Select)
How can DME and VOR be manually tuned?
MCDU NAV RAD Page.
Auto tune will be disabled until manual tune is deleted.
Is Ballast Fuel entered into MCDU?
No, it is incoporated into AWABS
How to perform the FUEL SYSTEM TEST?
It is a maintenance function only.
What is the purpose of the START PUMP?
A DC start pump, located in the right main tank,
provides fuel pressure for starting the APU or
engines when AC power is not available
Fuel tank capacities?
Mains - 9,300 lbs
Center - 6,000 lbs
Total: 24,600 lbs
Recall the Fuel Return to Tank (RTT) process
Excess warmed fuel cycling through the engine fuel system is returned to the inboard,
cooled corner of each main tank
This process warms the fuel in the tank and retards wing ice formation due to cooled
fuel
Fuel return to tank flow may be inhibited by the EEC for many reasons, including:
takeoff, landing, main tank fuel low, or high fuel temperature
Describe the use of FUEL X-FEED lever
A FUEL X-FEED lever, on the pedestal, permits
routing of fuel from either main fuel tank to one
or both operating engines. Cross-feeding is
enabled when the valve is opened and the
boost pumps on the receiving side are turned off
It may also be used to balance left and right
main tank fuel quantities
Recall features of the Fuel Venting system
The fuel vent system permits equalization of pressure between tanks during all fuel
conditions and also prevents siphoning and spilling of fuel during normal flight and
ground maneuvers
Right and Left main tanks are vented to the center tank. This also permits overflow
from the main tanks to drain into the center tank during fuel return to tank operation
with the main tanks full
Center tank fuel is vented to the wingtip vent boxes
Recall how the APU is supplied fuel
The APU normally is supplied fuel from the right main tank, however, if the center tank
contains fuel and its pumps are on, the center tank will supply the APU
Recall APU fuel usage for ground operations
Recall APU fuel usage for ground operations
Recall the function of the AUX hydraulic switch
The electrically driven auxiliary pump, located in the right wheel well has two
purposes: to back up the right engine-driven pump and to pressurize the hydraulic
systems on the ground when the engines are not running
If the right engine driven pump fails, or the right engine fails, the AUX pump may
be used to operate all right system components, including the landing gear
The auxiliary pump has built-in thermal protection and automatically shuts down if
it overheats
Recall the function of the HYD CONT RUDDER switch
Allows selection of manual rudder operation
When the switch is pushed, OFF illuminates,
hydraulic power to the rudder is shut off, and the
rudder reverts to manual operation
Recall the function of the TRANS pump switch
The transfer pump, located in the left wheel well,
enables a pressurized system to mechanically power
an unpressurized system when both system reservoir
quantities are normal
ON – opens valve on each side of Power Transfer Unit (PTU) to connect left and right
systems
OFF - closes valve on each side of PTU to disconnect left and right systems
Recall associated precautions with Hydraulic System Test
WARNING: Do not establish hydraulic power which will result in flap, slat, or spoiler
movement unless the wing/flap area has been cleared of personnel and equipment
If possible, coordinate with ground crew or another flight deck crewmember to obtain
clearance to turn on the TRANS and AUX HYDRAULIC pumps. If no outside observer is
available, the TRANS and AUX pumps may be turned on using an alternate procedure
(SP.13)
Recall the effect of electrical failure on the Engine Driven Hydraulic Pumps
When electrical power is removed from an engine-driven pump, the pump defaults to ON
