3.2 WARNINGS
3.2.1 NOT ENOUGH FUEL
When the rotary switch is in FUEL TO DEST. position, the
information in the display window flashes if fuel on board is
insufficient to reach either the destination selected as the
active waypoint or the final destination (if that total distance
record is provided in the serial message). Display window
shows amount of fuel short to reach destination preceded by
a negative sign.
3.2.2 RESERVE FUEL WILL BE USED
With the rotary switch is in F. AT DEST. position, the
information in the display window flashes if the aircraft will
arrive at the destination with less than the pre-programmed
Endurance Warning Time minutes of fuel - calculated at the
present cruise power setting. This warning is intended to
alert the pilot that the prevailing condition will require the
use of some of the selected reserve fuel to reach the
destination.
3.2.3 LOW ENDURANCE
The Microflo-L can be configured to display a warning
based on the time remaining to fly. When the rotary switch
is in the ENDURANCE position, and the actual endurance
is less than the pre-programmed Endurance Warning Time,
the data in the right half of the display flashes. Press the
TEST/ENTER button to acknowledge the warning. (Note:
Resetting the Microflo-L or adding fuel resets this condition
and the warning is enabled again).
3.2.4 LOW FUEL REMAINING
The system displays “Lo FUEL” when the fuel remaining
reaches the pre-programmed Low Fuel Level configured in
setup. Fuel flow information will not be displayed again
until the pilot acknowledges this word by pressing the
ENTER/TEST button. Fuel calculations are not interrupted
by this message. (Note: Resetting the Microflo-L or adding
fuel resets this condition and the warning is enabled again).
