4.4 FUEL LEVEL SENSORS CHECKINGS
To setup correctly the FL1 you need to know what type of
fuel level sensors are installed in your aicraft. The resistive
sensors can be of two types:
● Sensors that increase resistance as the fuel level
increase.
● Sensors that decrease resistance as the fuel level
increase.
If you don't know what type of resistive sensors are
installed in your aircraft follow this procedure:
● Empty the tank that you want to check.
● On the FL1 enter in the calibration for that tank (from
the setup menu press the knob for 3 seconds on “Left
t. calibration”, “Right t. calibration”, “Main t. calibration”
or “Aux t. calibration”).
● From the screen that appear annotate the numerical
value indicated in picture:
