Question 1

FU1

What happens when the cross-feed is placed in LOW 1?

Answer 1

The pump turns off in tank one and the cross feed valve opens.

Question 2

FU2

Is a takeoff allowed with the Fuel Inbalance EICAS message displayed?

Answer 2

As long as the imbalance limitation of 800 lbs is not exceeded.

The EICAS message remains illuminated until the imbalance is within 100lbs. If the XFEED remains out of the OFF position with less than 100lbs imballance the FUEL EQ XFEED OPEN message will be open.

Question 3

FU3

What does the EICAS warning FUEL 1(2) LO LEVEL mean?

Answer 3

Less than 460 lbs of fuel remains in the respective tank

Answer 4

Automatic fuel transfer begins with both wing tanks have a quantiy less than 4630 lbs each for 30 seconds

Question 5

FU5

Tank 1 has 3500 lbs. Tank 2 has 3700 lbs. How should the cross-feed switch be positioned to balance fuel

Question 6

FU6

Is it possilbe to transfer fuel between the main wing tanks

Answer 6

NO

Question 7

FU7

What happens if teh selected fuel pump fails?

Answer 7

The remaining fuel pumps are automatically switched on and start cycling until the pilot selections one of them?

Question 8

FU8

Is fuel crossfeed available without normal DC power?

Answer 8

Yes the valve is essentialy powered

Question 9

FU9

Can you transfer fuel from the Ventral tank and crossfeed at the same time?

Answer 9

No

Crossfeed inhibits ventral tansfer

Question 10

FU10

Answer 10

Fuel orders over 10,470 lbs

Question 11

FU11

When is crossfeed operation permitted?

Answer 11

During all phases of operation except for takeoff and go-around

Question 12

Answer 12

The right fuel tank (Tank #2)

Question 13

FU13

Answer 13

When unaticipated circumstances may result in landing at the destination or alternate (if required) with less than reserve fuel

Question 14

FU14

When the fuel quantity indicating system is MEL’s is the

FUEL LO LEVEL message viallied if luminated

Answer 14

Yes

Message is based on the fuel level dectected by the low-level sensor

Question 15

FU15

Is it acceptable to depart the gate with less than planned fuel?

Answer 15

Yes as long as the crew anticipates that the airplane will take off with more than MINF

Question 16

FU16

What is the fueling tolerance for ERJ aircraft?

Answer 16

The fuel loaded on teh aircraft may not exceed the gate fuel figure listed on teh Disptach Release unless amended in cooperation with the dispatcher

Question 17

See the QRH

Question 18

FU18

BAR method

Burn+Alternate+Reserve

Question 19

Answer 19

Minimum fuel should be declared when its determined that a landing at the destination (or an alternate) will be made with less than the planned reserve on the dispatch release.

Question 20

FU20

What are some examples of when the PIC is requred to notifiy the dispather about a change from teh planned release?

Answer 20

• deviations adding more than 15 minutes to the ETE
• Altitude changes if fuel-planning computations increse teh planned fuel burn casuing the depletion of the CONTG and SCF/TNK fuel not burned proir to take off
• Any change that will cause the flight to arrive at the destination or designated alternate airprot will less than minimum FAR fuel reserveres
• Any diverstion to an alternate airport, unless prevoiulsy discussed with the dispatcher.
• Any change in the intended destination or designated alternate airport.
• Any condition that affectes the safty of the flight

Question 21

FU21

Wht minimum fuel is required for takeoff when utillizing a CDR?
