Fuel quantity along with fuel burned infor-
mation is displayed on the FUEL system
schematic (Figure 5-4). This schematic can be
brought onto the display by depressing the
bezel button directly beneath the word FUEL
on the system menu line at the bottom of the
EICAS/MFD display. The schematic contains
rectangular shaped boxes which represent the
wing tanks and fuselage tank. The lines con-
necting the boxes represent the fuel lines be-
tween the tanks. There is a pointer and a color
bar on the edge of each box which provides an
analog format for indicating the relative
amount of fuel in each tank. There is also a dig-
ital readout of the amount of usable fuel in each
tank and a digital display of the total fuel on
board at the top of the schematic.
Also, on the schematic below the fuselage
tank is a digital display of total fuel used. The
pilot should zero out the fuel used amount be-
fore each flight to provide a backup to the
quantity indicating system. The fuel used
quantity can be zeroed out by depressing and
holding the FUEL USED RESET button lo-
cated on the fuel control panel (Figure 5-7) for
at least two seconds.
The Radio Management Units (RMUs) have
the capability of providing two display pages
of engine and system indications (Figure 5-5).
If the pilot’s inboard display unit (DU 2)
should fail, causing loss of the EICAS display,
including fuel flow indication, fuel quantity
indication, and fuel system schematic, the
EICAS display format can be selected on dis-
play unit (DU 3). If it is not possible or de-
sirable to display the EICAS format on either
inboard display unit for some reason, the en-
gine pages may be displayed on either RMU.
Selection of the engine pages may be accom-
plished manually by depressing the page (PGE)
function key at the bottom of the RMU. A page
menu will then be displayed on which “EN-
GINE PGE 1” or “ENGINE PGE 2” can be se-
lected by depressing the adjacent line select
key. The bottom left line select key, labeled
“MORE” is then used to alternately step be-
tween the two pages (Figure 5-5). For fuel sys-
tem monitoring, the left and right wing fuel
quantity is displayed on ENGINE PGE 1, and
fuel flow is displayed on ENGINE PGE 2.
