Display Modes and Operating Features:
1. Digital LCD Display and LED Display Mode Indicators:
If the digital LCD display backlight has been permanently powered up (as recommended), the display will be
easier to see during low ambient light conditions and at night. In direct sunlight the digital LCD display is easy to
see.
During night operation the green LED Display Mode Indicators may be too bright. If so, turn the panel light
rheostat up and the LEDs will dim. The two red Warning LEDs will always be displayed at full intensity.
2. Low Fuel Warning LED:
There are two pilot programmable Low Fuel Reminder Limits that will blink the red Low Fuel Warning LED
when violated. One may be set for a low fuel level and the other may be set for a time to empty value (see the
Pilot Programmable Modes section of this manual). When either of these two limits are violated the red Low
Fuel Warning LED will start to blink. Pushing any button or switch will stop the blinking and turn off the warning
LED. Also, a bar in the upper or lower left corner of the display will be shown when displaying REM or T. to
E. depending on which limit is violated.
There is one pilot programmable Low Fuel Warning Limit that will blink the red Low Fuel Warning LED
when the limit is violated. This limit is set for a low fuel remaining level (see the Pilot Programmable Modes
section of this manual). When this limit is violated the red Low Fuel Warning LED will start to blink. Pushing any
button or switch will cause the LED to stop blinking and go solid red. Also, a bar in the lower left corner of the
display will be shown when displaying REM.
This limit is an emergency warning
and should be set to the
lowest acceptable fuel level.
3. H/L Pressure Warning LED:
There are pilot programmable High and Low Fuel Pressure Warning Limits that will blink the red H/L PRESS
Warning LED when violated. Pushing any button or switch will cause the LED to stop blinking and go solid red.
If the High Limit is violated, a bar in the upper left corner of the display will be shown when displaying PRESS.
If the Low Limit is violated, a bar in the lower left corner of the display will be shown when displaying PRESS.
4. Power-Up:
When the aircraft master switch is turned on, the FP-5 will perform a self-diagnostics test and flash the red
warning LEDs. This allows you to check the Warning LEDs for proper operation.
After power-up, the FP-5 will blink the Fuel Remaining (REM) LED, and display the fuel remaining in the
tank(s). The REM LED will continue to blink until any button or switch is pushed. The blinking REM LED
is intended as a reminder to update the FP-5 if youve added fuel to the aircraft since the last flight (see REM
Display Mode).
5. FLOW Display Mode:
