RESERVE:
The desired reserve, as entered or verified by the operator, displayed
in pounds or kilograms. This may require periodic verification or
update. (Figure 2-50)
FLOW:
The current fuel flow in pounds or kilograms input automatically from
fuel flow indicators. (MAN) indicates a pilot manual entry and the entry
must be manually verified and periodically updated. (Figure 2-51)
NOTE: The above three quantities will flash after 15 minutes and will
require verification by using the Line Select and ENT Keys if MAN
fuel flow was selected.
VERIFY INPUTS:
Each of the flashing values
must be verified or entered
by pressing the ENT Key
when the cursor is over each
field. This field is only dis-
played after the system is
turned on and will be dis-
played in place of the LAST
INPUT field on line 6. (Figure
2-51)
LAST INPUT:
The time in hours and minutes since the above three quantities were
verified. This field only appears if fuel flow is input manually. (Figure
2-51)
NOTE: This field displays VERIFY INPUTS at system turn-on since
REMAINING and RESERVE are stored in non-volatile memory dur-
ing system shut-down.

ty is reached. (Figure 2-50) Fuel flow and ground speed must be
