Fill Threshold – This setting is used to determine if the fuel quanitity should be confirmed upon system
power up. During power up, the sytem compares the current fuel quantity to the fuel quantity recorded
when the system was last shut down. If the current fuel quantity exceeds the previous fuel quantity by
more than the fill threshold amount (10 gallons shown in previous figure) the system will assume that fuel
has been added and will pop up a reminder page prompting the pilot to confirm the quantity of fuel on
board.
Trim/Flap Position Input Calibration – The POS inputs require calibration if configured for any of the
trim positions (elevator, aileron, rudder) or flap position.
To perform the Trim/Flap Position calibration:
1. Press the Calibrate softkey to display the Calibration Page.
2. Position the elevator to match the trim position (up/left, neutral, down/right) displayed on the cali-
bration page, or position the flap to the desired position.
3. Note the resulting sensor value (in volts) displayed in the Sensor Value field (the sensor value
should change with each change in trim/flap position.
4. Highlight and press the Calibrate button.
5. Repeat this process for each of the Trim/Flap Positions.
NOTE
Flap position values (up to 8) should coincide with the angle of the flap position as
expressed in degrees (-90° – +90°).
To delete a calibration value, highlight the desired data in the list, and press the CLR Key. Then highlight
Yes on the pop-up window, and press the ENT Key, the calibration data is removed.
