4-2 EFIS-D10A Installation Guide
SETTING MAGNETIC INCLINATION ANGLE AND INTENSITY (REQUIRED)
To calibrate your EFIS-D10A heading, you must input your location’s current magnetic
inclination angle and intensity. Before doing this, you must obtain these two values for
the geographic location where you will be performing the calibration. Note that this
procedure only needs to be done once, prior to magnetic calibration. Moving the aircraft
to another location does not require repeating this procedure.
Obtaining Magnetic Inclination and Intensity
1. Browse to web page: www.dynonavionics.com/docs/maginfo.html . (Looking up this
information does not have to be done on a computer at the plane, with live Internet
access.)
2. The Dynon Avionics “Magnetic Inclination and Intensity” web page is updated as
needed; it contains a link to a NOAA web pages and instructions for easily finding your
local magnetic inclination and intensity by inputting your ZIP code (in the US) or your
latitude and longitude and inputting the resulting data into your Dynon EFIS.
3. Follow the instructions listed on the web page, especially clicking the “Compute
Magnetic Field Values” button at the bottom of the linked page – the values required by
your Dynon EFIS will be displayed only after clicking that button. If you are near the
equator or in the southern hemisphere, note that the inclination may be negative number.
Entering inclination and intensity into the EFIS-D10A
1. Enter the inclination setup menu by pressing any button beneath an EFIS page (except the
far left or far right hotkeys), then MORE > SETUP > MORE > MORE > MAGINC
2. Press INC or DEC to increment or decrement the displayed inclination angle. Press and
hold to change values more rapidly.
3. When the display shows the magnetic inclination angle for your location, press BACK to
leave the menu.
4. Enter the magnetic intensity setup menu by pressing any button beneath an EFIS page
(except the far left or far right hotkeys), then MORE > SETUP > MORE > MORE >
MAGINT
5. Press SEL to change the digit being incremented or decremented. Press INC or DEC to
increment or decrement the selected digit. Press and hold to change values more rapidly.
6. When the display shows the magnetic intensity for your location, press BACK to leave
the menu.
