3 System Overview
The EFIS-D10A features internal, calibrated solid-state sensors and a digital screen display to
present Airspeed, Altitude, and Attitude data. In a SkyView HDX system, it serves as a Standby
Flight Display for the Primary Flight Display (PFD).
The Standby Flight Display provides pilots with immediate Primary Flight Information (PFI) in
case of a SkyView HDX system failure. It also allows pilots to cross-compare the presented PFI
to ensure data integrity.
Figure 1: EFIS-D10A
3.1 Basic Control and Operation
Operating the EFIS-D10A is intuitive for people familiar with flight instrumentation. Basic
operation happens via the front panel. The front panel contains buttons and a display. There are
six buttons on the front panel of the EFIS-D10A. The buttons are referred to as 1 through 6, with
button 1 being the leftmost and button 6 being the rightmost. The buttons are used to turn the
unit on and off, access and scroll through menus, and adjust instrument parameters.
Figure 2: EFIS-D10A Buttons

Page | 3-2
EFIS-D10A - Installation and Maintenance Manual, Rev D, 10/21/2021
3.1.1 Menu System
All interaction with the EFIS-D10A is accomplished using its menu system. The menu system is
accessed and navigated via six buttons and associated labels. To enter the menu system, press
any button (except 1 and 6). To exit the menu system, press the BACK button as many times as
needed.
Figure 3: EFIS-D10A Menu System
A menu consists of two rows containing text. The upper row contains a tab that denotes the
currently displayed menu. The lower row contains six labels that denote the function of the button
below it. Onscreen elements move up to avoid the menu. This prevents the menu from obscuring
useful data while it is being displayed. 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.
If a menu contains more options than there are buttons, the MORE label is displayed over button
five. Pressing this button presents the next set of options in the current menu.
In any menu, press the BACK button to return to the previous menu and save changes. In all
top-level menus, button six is the EXIT button. Pressing EXIT removes the menu system and
moves the onscreen elements down to their original positions.
3.2 System Operation
No special operating procedures are required for using the EFIS-D10A.
Operating limitations for the EFIS-D10A are listed in the 103272-000 SkyView HDX Airplane
Flight Manual Supplement document at dynoncertified.com/certified-documentation.

4 Certified Installation Compliance
Some airplanes may have been modified from their stock type design, and consequently, it may
be difficult to use the information in this manual to completely substantiate the installation in
compliance with the STC. It is the installer's responsibility to make the final determination of
applicability for each individual airplane.
Prior to completing the installation, and before returning the aircraft to service, the installer must
complete and submit a completed FAA Form 337 Major Repair & Alteration (Airframe,
Powerplant, Propeller, or Appliance). The form must include the following:
• Description of the EFIS-D10A installation.
• Appropriately approved or acceptable data that demonstrates compliance.
Refer to AC 43.9-1G - Instructions for Completion of FAA Form 337 for additional information.
4.1 Pre-installation Information
Read and understand the following before proceeding with installation activities.
Always install avionics equipment in accordance with the instructions in this
manual and the guidance and approved engineering methods outlined the
following FAA documents:
• 23.1311-1C - Installation of Electronic Display in Part 23 Airplanes
• AC 43.13-1B - Acceptable Methods, Techniques, and Practices - Aircraft
Inspection
• AC 43.13-2B - Acceptable Methods, Techniques, and Practices - Aircraft
Alterations
The certified mechanic who will authorize the airplane's return to service should
agree with the installation plan (i.e., methods, unit location, wire harness routing,
etc.) before installation activities begin. This will help avoid potential rework should
any part of the installation be found non-compliant.

5 Installation
This section provides information and instructions for installing the EFIS-D10A.
5.1 Mechanical Installation
The Dynon EFIS-D10A must be installed within the primary maximum field-of-view boundary, as
close as practicable to the SkyView HDX display. According to AC 23.1311-1C, the primary
maximum field-of-view is based on vertical and horizontal visual fields from the pilot's eye
reference point that can be observed with eye movement and minimal head movement only.
The EFIS-D10A is designed to surface mount to the instrument panel in standard
instrument holes (3.125" diameter) with little modification.
Observe the following guidelines when installing an EFIS-D10A:
• Unit should be installed so it is level horizontally.
• Wire harness extends about 3" (76.2 mm) from the rear of the unit.
• Front bezel will extend 0.8" (20 mm) beyond the face of the instrument panel.
• Unit will need to be accessed during service, therefore, plan to provide enough slack
in wire harness and pitot and static lines to disconnect and reconnect them if unit is
removed from instrument panel.
• Avoid placing the unit near heater vents or sources of extremely hot air.
