Problem Solution
After performing a magnetic
calibration the FlightDEK-
D180‘s heading is wrong by a
constant amount.
Orient your plane in a known direction, preferably on a
compass rose at the airport. Navigate to the Heading
Adjustment menu by pressing SETUP > MORE > MORE >
MAGADJ. Increment or decrement the value of the heading
until the FlightDEK-D180 heading corresponds to the
direction in which your plane is pointed.
When the barometer on the unit
is set correctly, the displayed
altitude is wrong by a constant
amount at all altitudes.
Set the barometer to the correct value for your current
location. Note the difference between the displayed altitude
and the actual altitude for your location. Navigate to the
Altitude Adjustment menu by pressing SETUP > MORE >
ALTADJ. Increment or decrement the value of the altitude
until the FlightDEK-D180 altitude corresponds to that of the
current location of your plane. If you need to adjust by more
than 200 ft, or find that you need to adjust frequently (after
setting your baro), please call Dynon Technical Support for
assistance.
Airspeed is inaccurate by
between 1 and 10 knots (or
equivalent, in other units) at
takeoff speed.
You may recalibrate your FlightDEK-D180‘s zero pressure
value. With your plane in as windless an environment as
possible (e.g., a hangar), cover both the pitot and static ports
with a sock or cloth to minimize airflow without putting
pressure on the ports. Next, on the FlightDEK-D180, enter
the EFIS main menu, press MORE > SETUP > MORE >
MORE > MORE > SPDCAL. When you are confident that
there is no pressure on the pitot and static ports, press either
button corresponding to SET ZERO PRESSURE. Press YES
to confirm you have zero pressure on the pitot and static
ports. You will see a message indicating that the unit is
calibrating. This should only take a few seconds. On your
next flight, verify that the airspeed is what you expect.
To reset the airspeed calibration to factory defaults, enter the
SPDCAL menu, and press RESET DFLTS.
FlightDEK-D180 displays
continuous or blinking blue
screen
Ensure that your power supply is capable of supplying at
least 2 amps and that it is at least 10 volts.
If, after verifying that you have met these two conditions the
unit does not operate normally, it is necessary to contact
Dynon Avionics.
FlightDEK-D180 screen stays
black when power is applied
Verify Master Power is connected.
Verify Master Power is above 10 volts.
FlightDEK-D180 indicates over
temperature condition
Provide additional cooling to instrument
FlightDEK-D180 indicates
incorrect heading
(Re)calibrate the magnetic heading using the procedure
described above.
