EFIS Calibration and Configuration
take as long as 5 minutes. A message will be displayed onscreen: CALCULATING
MAGNETIC CALIBRATION VALUES.
12. Wait for the message CALIBRATION COMPLETE before attempting to use the
FlightDEK-D180 or remove power. Press BACK to leave the menu.
This completes the EDC-D10A calibration process. The process can be repeated as often as
desired. The overall accuracy of the compass depends on the installation location (away from
any ferrous materials or current carrying wires or devices), the installation alignment (aligned
with the FlightDEK-D180 in pitch, roll, and yaw), and the calibration procedure (accurately
aligning the aircraft with North, East, West, and South and having the correct magnetic
inclination angle loaded into the FlightDEK-D180). If the compass performance is not adequate
for your usage, we suggest that you investigate each of these factors and try to optimize your
installation for each factor.
If the heading shown onscreen is off by a small, but constant amount, you can change a heading
offset in the FlightDEK-D180 which will correct this. Orient your plane in a known direction,
preferably on a compass rose at the airport. Navigate to the Heading Adjustment menu by
pressing MORE > SETUP > MORE > MORE > MAGADJ. Increment or decrement the value of
the heading offset until the FlightDEK-D180 heading corresponds to the direction in which your
plane is pointed.
Troubleshooting
During the calibration process you may receive one of the following errors. Next to each one is
the corrective action required.

Configure Airspeed Color Thresholds
To configure the airspeed bar color thresholds for your unit enter the EFIS > SETUP > IASCLR
menu. This displays the Airpseed Color Threshold menu. In this menu, enter the values for five
airspeed constants (Vso, Vs1, Vfe, Vno, and Vne), each of which has its own button. Enter these
values in units of knots, mph, or km/h depending on what airspeed units you are currently using
(you may change the displayed airspeed units via EFIS > SETUP > UNITS > IAS).
Perform the following steps for each airspeed constant:
1. Press SEL► to select the digit you wish to increment or decrement.
2. Press DEC- or INC+ to decrement or increment the selected digit.
