MAINTENANCE MANUAL
(6) Display Blanking
The LCD can be blanked at the operator's discretion. To select this operation, press the "BLK"
button. To exit this mode, select any analog indicator from the EMIS system stack or select any
other QDI/EDI function.
NOTE: Since the pushbutton designated for blanking the display has secondary functions
during exceedance review and fuel management mode, the display blanking function
is disabled during these modes of operation.
If an exceedance occurs, the blank mode will end and the exceedance will
automatically be posted.
(7) Fuel Management Mode
(a) QDI ( S/N’s 4636021 thru 4636131 only ). The QDI is linked to the fuel flow indicator in the
system stack through the data bus. Having this information available allows the QDI to
perform "Real Time" fuel management calculations. Fuel remaining, flight time remaining,
and fuel consumed can be selected on the display.
To enter the fuel management (posting) mode, momentarily press the "FUEL" button.
1 See Fuel Load Entry Mode, below, for the fuel load entry procedure.
2 If a fuel value had previously been entered into the fuel computer, the fuel remaining
will be displayed in gallons. (See Figure 5A).
3 To view the flight time remaining, momentarily press the "FUEL" button a second
time. (See Figure 7A).
NOTE: In the event no fuel flow is detected, the flight time remaining will be
displayed as "----". (See Figure 7B). When the calculated flight time
remaining has expired, "0.0" will be displayed. (See Figure 7C).
4 To view the fuel consumed, momentarily press the "FUEL" button a third time. The
fuel consumed will be displayed in gallons (See Figure 8A). As long as fuel flow is
detected, the fuel computer will continue to update the fuel used.
5 Continuing to press the "FUEL" button repeatedly will simply cycle through the three
fuel management displays.
6 To exit the fuel management mode, return to the normal digital enhancement mode
and select any analog indicator in the EMIS system stack or any other function of the
QDI.
NOTE: The memory allocated for the fuel management mode is non-volatile.
(b) EDI ( S/N’s 4636132 thru 4636374 ). The EDI is linked to the fuel flow indicator in the
system stack through the data bus. Having this information available allows the EDI to
perform "Real Time" fuel management calculations. Fuel remaining, flight time remaining,
and fuel consumed can be selected on the display.
1 To enter the fuel management (posting) mode (see Figure 8B), momentarily press
the "FUEL" button. If a fuel value had previously been entered into the fuel computer,
the Fuel Remaining (REM) will be displayed in gallons, as well as: Endurance
(ENDUR), Nautical Miles Per Gallon (NMPG), Total Fuel Used (USE), Gallons To
Destination (GAL TO DEST) and Gallons At Destination (GAL AT DEST).
2 To exit the fuel management mode and return to the normal digital enhancement
mode push the “INST” button.
