What is the purpose of the scavenge ejector?
3 scavenge jet (ejector) pumps maintain the fuel level in the collector tank,
ensuring a constant flow of fuel to the engine during normal flight.
What is the primary purpose of the Main Ejector?
The primary wing fuel pump is a venturi ejector pump (jet pump) with
no moving parts, and is powered by the respective engine motive flow.
It is a self-sustained pump and does not require electrical power to
operate.

- During respective engine start.
- Crossfeed operations.
- APU, when engine is not running.
- Main Ejector Pump failure.
With the knob in AUTO, when will the DC Fuel Pump turn on?
A DC electric fuel pump is installed only in the right wing tank. It provides pressurized fuel for normal APU operation and engine start, when AC power or the AC fuel pump is not available.

FADEC will automatically abort an engine start in the event that:
Hot, Hung, No Light Off.
When will CLB thrust be set automatically on the EICAS?
During aircraft power up, CLB-1 is the default mode setting. Whenever
the selected takeoff thrust is lower than CLB-1 the CLB-2 mode
becomes the default until the next airplane power down / power up. This logic is to prevent the system from increasing thrust instead of
reducing it during transition from TO to CLB after the takeoff.
During takeoff with flight director ON, the CLB mode is engaged when
all of the following conditions occur:
– landing gear retracted
– airplane altitude above 400 ft AGL
– any change in the flight director vertical mode.
During takeoff with flight director OFF, the CLB mode is engaged when
all of the following conditions occur:
– landing gear retracted
– airplane altitude above 3000 ft AGL.
When will CRZ thrust appear on the EICAS?
The CRZ mode is engaged when all of the following conditions occur:
– Airplane is leveled at the altitude set on the altitude preselector for
90 seconds.
When will GA thrust appear on the EICAS?
The GA mode is activated in flight whenever the landing gear and flaps
are down.
When will RSV thrust appear on the EICAS?
The ATTCS automatically commands RSV whenever it is engaged,
thrust levers are at TOGA position, and one of following conditions
occurs:
1. Difference between both engine N1 values is greater than 15%;
2. One engine failure during takeoff;
3. One engine failure during go-around;
4. Windshear detection.
The RSV mode is manually activated by moving the thrust levers to
MAX position whenever the ATTCS is engaged.
When FADEC automatically aborts an engine start, why must we still conduct the memory item?
To close the starter valve / respect starter limit.

What happens when the dump button is pressed while the mode selector is in AUTO?
- Sets the ECS packs OFF;
- Recirculation fans to OFF;
- Controls the OUT FLOW VALVE to maintain the cabin altitude rate
of climb at 2000 ft/min up to 12400 ft. - When the cabin altitude reaches 12400 ft it commands the OUT
FLOW VALVE full closed. From this point the cabin altitude rises by
natural leak.
What happens when the dump button is pressed while the mode selector is in MAN?
The Dump Function is not available in Manual Mode. However, if the
associated push button is pushed in, both recirculation fan and packs
are turned to off.
When/Why would I use the LFE CTRL on the pressurization panel?
If landing field elevation is not available from the FMS database. Pilot must manually input it using LFE control (field elevation shown in CYAN vs normal green).
What does the outflow valve do?
The outflow valve modulates airflow from the pressurized cabin into surrounding environment. It can be modulated automatically or
manually.
What does the positive pressure relief valve do (safety valve)?
The positive pressure relief valve is a spring loaded check valve that works without any electrical power, and is independent the CPCS. Its
function is to protect the airplane’s structure against damage due to positive overpressure. In case of outflow valve failure, the positive pressure relief valve opens if the pressure differential between cabin
and surrounding environment exceeds 8.6 psi.
What does the negative pressure relief valve do?
The negative pressure relief valve is a spring loaded check valve that works without any electrical power, and is independent of the CPCS.
Its function is to protect the airplane structure against damages due to a negative differential pressure.
The negative pressure relief valve opens if differential pressure between cabin and surrounding environment exceeds-0.5 psi.
What do the Cabin Pressure Controllers do?
The basic function of the controller is to control cabin pressure by commanding the outflow valve to modulate airflow through the valve
from the pressurized airplane volume to the surrounding environment. The CPC has two fully independent automatic channels, which are alternated following each flight. Both channels provide a manual function as backup, enabling the crew
to control cabin pressure by directly actuating the outflow valve (OFV) position.

Ground: - Flaps selected to any position greater than 0° and:
–Thrust levers set to takeoff thrust, or
–Ground speed greater than 50 kt. - Engine 1 running and parking brake released.
- During Engine 1 start (once N2 reaches 40%) if parking brake has been applied within the last 6 min.
When, in AUTO, will ACMP 3B turn on?
Whenever 3A fails, 3B activates.
