EFIS Instrument won't turn on with just battery
This behavior should be improved in a future firmware version.
Heading tape flashes "Remote Compass Not Detected"
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 get in touch with us 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.
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.
EFIS Instrument screen stays black when power is applied
- Verify Primary Power is connected.
- Verify Primary Power is above 10 volts.
EFIS Instrument indicates over temperature condition
- Provide additional cooling to instrument
EFIS Instrument indicates incorrect heading
(Re)calibrate the magnetic heading using the procedure described in the Installation Guide.
Internal battery life is too short
Verify internal battery is charged to above 16 volts using FlightDEK-D180 voltmeter. Re-run capacity test. Replace battery if insufficient capacity.
Clock setting is lost
If present, verify internal battery is charged. If no internal battery, verify Keep Alive power is supplied to unit at all times.
Cannot make connection with PC
Verify wiring is correct. Verify no other programs using the COM port are running on the PC. Verify latest version of The Dynon Product Support Program is being used.
Unit will not boot off battery power
This can be normal behavior for the FlightDEK-D180. When booted off master power, the FlightDEK-D180 will have no problem continuing to run off battery power. However, at startup, it draws more current than the battery can provide.
