1. INTRODUCTION
Thank you for purchasing the Dynon Avionics EFIS-D10A. This section provides some important cautionary
information and general usage instructions for this manual.
Before You Fly
We strongly recommended that you read this entire guide before attempting to use the EFIS-D10A in an actual flying
situation. Additionally, we encourage you to spend time on the ground familiarizing yourself with the operation of the
product. While first learning to use the instrument in the air, we recommend you have a backup pilot with you in the
aircraft. Finally, we encourage you to keep this manual in the aircraft with you at all times. This document is designed to
give you quick access to information that might be needed in flight. CAUTION: in a flying situation, it is the pilot’s
responsibility to use the product and the guide prudently.
OEM Installations
EFIS-D10A Pilot’s User Guide 1-1
If your EFIS-D10A is installed by an OEM distributor, you may find that you are unable to access some menus and
settings. Some Dynon distributors customize various areas of the EFIS-D10A firmware to maintain a consistent pilot
experience and minimize integration issues across a large number of installations. Currently, OEMs can customize
access levels to the following settings on Dynon systems: EMS GLOBAL setup menu, EMS SENSOR setup menu, fuel
calibration, trim calibration, flaps calibration, GPS/Nav setup menu, screen configurations, and checklists/data panels.
OEM distributors have the option of customizing some or all of these areas. Please contact your aircraft's manufacturer if
you have any questions about how your unit has been customized.

hyperlinks taking you to the relevant location in the manual. The latest version of this manual may be downloaded from
our website at www.dynonavionics.com.
The following icons are used in this guide:
Any text following this icon describes functionality available only with the HS34 HSI Expansion Module
connected to your system.
Any text following this icon describes functionality that is possible when multiple Dynon Avionics products are
networked together via the Dynon Smart Avionics Bus (DSAB).

2. PRODUCT OVERVIEW
This section provides a general overview of the various parts of the EFIS-D10A as well as a theory of operation. The
information in this section serves as a reference only and helps familiarize you with the inner workings of the unit. It
should not be used for diagnostic or reparative work.
EFIS-D10A Hardware
The EFIS-D10A uses solid-state sensors to provide accurate and reliable information about your flying environment in
an easy-to-use interface.
POWER
The EFIS-D10A requires between 10 and 30 volts DC for operation and has inputs for an external backup power supply
and a keep-alive voltage. It is acceptable to have the EFIS-D10A turned on during engine start.
EFIS-D10A Pilot’s User Guide 2-1
The EFIS-D10A can be ordered with an optional internal battery which allows the instrument to continue to operate in
the event of an external power failure. This lithium-ion battery is rechargeable and is managed by the EFIS-D10A. If the
always-on Keep Alive circuit is connected, the EFIS-D10A continues to charge its internal battery even if the instrument
is turned off. This ensures that your internal emergency battery is always fully charged. Under normal conditions, the
internal battery should have a voltage between 13 and 16.8 volts. When the battery’s voltage drops below 13 volts, the
EFIS-D10A displays a low battery warning. When new, a fully charged internal battery is rated for a minimum of 1.5
hours of normal operation with the EFIS-D10A. If the EFIS-D10A has switched to its internal emergency battery due to
a power loss in your aircraft, it is advised that you land as soon as possible.

Product Overview
2-2 EFIS-D10A Pilot’s User Guide
SENSORS AND INPUTS
Attitude information is obtained from 3 solid-state gyrometers, 3 solid-state accelerometers, and the airspeed pressure
sensor. Heading information is obtained from 3 solid-state magnetometers housed in the EDC-D10A. Airspeed, altitude
and angle of attack are obtained from three separate pressure transducers.
HSI information can be displayed when connected to Dynon’s HS34, a Garmin SL30, or a compatible GPS unit.
DYNON SMART AVIONICS BUS
If you have multiple Dynon Avionics products in your aircraft, they may be networked together via the Dynon Smart
Avionics Bus (DSAB). Units networked via DSAB have the ability to transmit information to each other. Any product's
data can then be viewed on any other screen in the DSAB network. For example, an EFIS has the ability to display
engine monitor information if it is connected to an EMS or FlightDEK-D180.
Note that the failure of a unit in a DSAB network may cause the loss of some or all data shared between units. In the
above example, if the connected EMS/FlightDEK-D180 were to fail, the EFIS would no longer be able to behave as an
engine monitor. For more information on DSAB-specific alerts, refer to the DSAB Alerts section on page 7-3.
OUTPUTS
The EFIS-D10A has an output to drive an external customer-supplied audible device for AOA (if installed) and altitude
alerts.
A serial output is also provided for serial altitude encoder data. An optional Serial-to-Gray Code Converter is available
for connection to Mode C Gray Code transponders.
A connected HS34 can output voice annunciations for many of the alerts generated by the EFIS-D10A.

Product Overview
EFIS-D10A Pilot’s User Guide 2-3
DISPLAY
The display is a 4-inch, 320 by 240 pixel, 450-nit LCD screen. It is acceptable to have the EFIS-D10A turned on during
engine start.
BUTTONS AND KNOBS
User interaction takes place via the six buttons along the bottom of the front panel of the unit.
When configured to control the EFIS-D10A, the HS34’s VALUE knob changes values when in various EFIS
menus and adjusts the barometer setting when no menus are displayed. The HS34’s HEADING and COURSE
knobs affect their respective parameters on the HSI page.
Theory of Operation
The primary flight instruments on your EFIS display are generated using a group of calibrated sensors. All of them are
solid state – that is, there are no moving parts. These sensors include accelerometers, which measure forces in all three
directions; rotational rate sensors, which sense rotation about all three axes; pressure transducers for measuring air data;
and magnetometers on all three axes for measuring magnetic heading.
The table below describes which inputs and sensors are used within the EFIS to generate the different displayed
instruments. It is not meant to enable in-flight troubleshooting, but is provided to convey how much of an integrated
system your EFIS is.

AN IMPORTANT NOTE ABOUT AIRSPEED
As depicted above, your EFIS-D10A depends on airspeed (pitot and static) for most of the other AHRS indicators. If a
problem develops with your airspeed reading, treat all of the instruments on your EFIS with skepticism – especially
attitude. Also, know that without airspeed, the EFIS instruments that depend on it are most prone to error when the
aircraft is accelerated. Hence, the less the aircraft is maneuvered (power application/reductions, and changes in
direction), the better the EFIS performs.

After reading this section, you will be familiar with the basics of how to use your EFIS-D10A. For details regarding
specific procedures (e.g., adjusting display brightness, changing the barometer, setting the clock, etc.) please refer to the
EFIS Operation section.
Front Panel Layout
All normal operation of the EFIS-D10A happens via the front panel. The
front panel contains buttons and a display.
•Buttons – There are six buttons on the front panel of the EFIS-
D10A. Throughout this guide, these buttons are referred to as one
through six, with button one being the leftmost and button six be
the rightmost. EFIS-D10A buttons are used to turn the instrument on

Screens contain one or two pages and pages
contain groups of similar information.
Display
The EFIS-D10A display is the most obvious and commonly used output of the device. It is capable of displaying EFIS,
HSI, and/or engine data simultaneously.
SCREENS AND PAGES
The terms in the following bulleted list are used in this section and are defined as follows:
•Screen/Screen Configuration – Screens consist of one or two pages
from the EFIS-D10A or from another DSAB-connected Dynon
Avionics product.
•Page – A page is a section of the screen that contains a collection of
related data. Pages may occupy the total area of the screen (i.e.,
100%) or share the screen with other pages (i.e., 1/2 split).
•Screen Rotation – The rotation is the list of screen configurations
which can be cycled to via the hotkeys. Your rotation is usually
smaller than the total list of available screen configurations.

CYCLING BETWEEN SCREENS
There are two methods for cycling between pre-defined screens: via the
menu and via hotkeys.
Screen Cycling Using the SCREEN LIST
Navigate to the SCREEN LIST menu by holding button six for at least
two seconds when no menu is present (see the figure to the right). Note
that if you only press button six momentarily, the display cycles to the
next screen in your screen rotation. Use the DOWN▼/UP▲buttons to
move the caret (>). The caret denotes the selected screen. Press GOTO►
to remove the SCREEN LIST and display the selected screen. If you wish
to stay on the same screen, you may either select your currently displayed
screen with the caret and press GOTO►, or press CANCEL.
Screen Cycling Using Hotkeys
With no menu displayed, press button one to cycle to the previous screen
in your rotation. Likewise, press button six to cycle to the next screen in
your rotation (see the figure on the next page). Cycling via hotkeys only
allows you to display screens that are in your screen rotation. They are
meant to give you quick access to the screen configurations that are most
important to you. If you wish to access screens that are not in your
rotation, use the SCREEN LIST as described above.
With no menus displayed, pressing button
six for two seconds displays the SCREEN
LIST menu, from which you may switch
to, and set up, various screen
configurations.
Hold for two seconds

Product Operation
EFIS-D10A Pilot’s User Guide 3-5
Changing the Screen Rotation
You may use the out-of-the-box screen rotation or define your own. If you desire to use the initial rotation, no user
configuration is required. If you desire to use a custom cycling order, then user configuration is necessary.
To configure a custom rotation, navigate to the SCREEN LIST menu
page by pressing button six for approximately two seconds when no
menu is present. Press SETUP, then press ROTATN to display the menu
used to change the boot and rotation screen. Scroll through the pre-
defined screens using the DOWN▼/UP▲buttons.
Press the BOOT* button on any selected screen configuration to make it
the screen that is shown immediately after the instrument is turned on.
Only one screen may be designated as the boot screen. Next, press the
TOGGL↕button on any selected screen to toggle the “↕” icon. All
screens that show the “↕” icon are included in the rotation. Any screen in
the rotation may be accessed via the button one and six hotkeys. Press
BACK to save any settings.
Changing the Screen List Order
You may wish to change the order in which screen configurations are
displayed in the SCREEN LIST, thus changing the order they are cycled
to via hotkeys. To do this, navigate to the SCREEN LIST menu page by
pressing button six for approximately two seconds when no menu is present. Press SETUP, then press ORDER to
display the menu used to change the screen order. Scroll through the pre-defined screens using the DOWN▼/UP▲
buttons. Press the MV DN▼button to move the selected screen down in the screen list. Likewise, press the MV UP▲
button to move the selected screen up in the screen list.

Menus
All interaction with the EFIS-D10A is accomplished through the use of its menu system. The
menu system is accessed and navigated via the six buttons located on the front of the unit.
PAGE-SENSITIVE MENUS
On a screen where no menu is already present, buttons two through five are used to display a
menu. With no menu displayed, pressing any one of these buttons causes the menu for the
page above it to show at the bottom of the screen. For example, if a screen is divided into two
pages with the left page occupying 1/2 of the screen and the right page occupying 1/2 of the
screen, then pressing EFIS-D10A buttons two or three (all below the left 1/2 of the screen)
displays the main menu for the left page and pressing buttons four or five (below the right 1/2
of the screen) displays the main menu for the right page (see the figure to the right).
FUNCTIONALITY
A menu consists of two rows of gray boxes containing text. The upper row contains one tab
that denotes the currently displayed menu. The lower row contains six labels that denote the
function of the button below it. Many of the onscreen elements move up to avoid the menu.
This prevents the menu from obscuring useful data while it is up. Upon exiting the menu, the
screen returns to its normal appearance.
Pressing a button either displays another menu or adjusts a parameter. If there is no text above
a button, then that button does not have a function in the context of that menu. Occasionally, a
button label spans two or more buttons. In this case, any button below the label invokes the
command.
The configuration of the
pages on the screen
determines which
buttons are used to
display a page's menu.
