1 General
SkyView HDX is an integrated system that aggregates air, engine, traffic, and navigation
information for display to the pilot. The information is portrayed on the SkyView HDX display,
which is a touchscreen, coupled with mechanical knobs and buttons. The SkyView HDX display
provides Primary Flight Information (PFI) on the Primary Flight Display (PFD), Map with current
position, and optionally Engine Monitoring information. Subsystems, such as the Autopilot,
Communications, Transponder, as well as third-party equipment integrate with SkyView HDX to
perform their functions.
Voice aural annunciations and written messages are used to alert the pilot to exceptional
conditions, such as departures from desired altitudes or exceeding engine parameter limits.
Airspeed, altitude, and attitude data is collected by the Air Data, Attitude, Heading Reference
System (ADAHRS.). Engine, fuel, and electrical system data is collected by the optional Engine
Monitoring System (EMS).
Navigation data is provided by an integrated GPS and by external navigation sources.
ADS-B In traffic data is provided by an integrated ADS-B In receiver. ADS-B Out capability is
provided by a position source and transponder, which have been shown to meet the
requirements of 14 CFR 91.227.
The system stores an onboard terrain and chart database for display as the VFR Map.
This document also contains information related to operating the optional SkyView Autopilot
system. Not every airplane is approved to be equipped with the SkyView Autopilot system.
1.1 Document Control
This document is released, archived, and controlled according to the Dynon Avionics document
control system. To revise this document, a letter is submitted to the FAA with the revision. The
FAA then accepts and approves any revision to the content listed in the FAA Approval section.
After FAA acceptance/approval, Dynon posts the revised document for customer use at
dynoncertified.com/docs. Only the latest revision of the document is made available. STC
owners and installers are notified of the new revision via an official Dynon Marketing email
release.

2 Limitations
The limitations listed in this section apply to all airplanes with a SkyView HDX system.
Autopilot limitations for specific airplane makes/models are listed in separate appendices at the
end of this document.

•SkyView HDX system must have at least one of each of the following components in
fully functioning condition, with no error messages displayed:
▪SkyView HDX display unit.
▪SV-ADAHRS-200 module.
▪SV-BAT-320 backup battery.
▪EFIS-D10A standby display.
▪Functioning external navigation source, either an IFR GPS Navigator or NAV radio.
•IFR flight with Yellow or Red Backup Battery indicator status displayed is prohibited.
2.2 Engine Monitoring Visibility
For all airplanes equipped with an Engine Monitoring System (EMS):
•Configuring the screen layout of a SkyView HDX display unit so the primary engine
instruments are not visible to the pilot is prohibited.
For twin-engine airplanes with an EMS:
•A secondary (non-PFD) Skyview HDX display unit must be installed and dedicated to
present Engine Monitoring information.
•The SkyView HDX display unit dedicated to present Engine Monitoring information must
be configured to always show (no exceptions) EMS information in either 100% or 50%
display page layout during takeoffs and landings.
2.3 Backup Power
For all airplanes:
•Backup power for both the primary and standby display systems must be checked prior
to IFR flight. (See Section 4.2: SkyView HDX Backup Power Check and Section 4.3:
Standby Flight Display Backup Battery Condition Check for instructions.)

SkyView HDX - Airplane Flight Manual Supplement, Rev Q, 11/5/2021
2.4 Synthetic Vision
For all airplanes:
•SkyView HDX Synthetic Vision is advisory in nature and must not be used as the sole
means of terrain and obstacle avoidance.
2.5 Map
For all airplanes:
•The SkyView HDX Map and Flight Planning function is advisory in nature and must not be
used as the sole means of terrain and obstacle avoidance.
2.6 Autopilot
For all airplanes equipped with the SkyView Autopilot system:
•Use of the autopilot when any servo shear screw is broken is prohibited.
•Use of the autopilot without a successful preflight operations check is prohibited. (See
Section 4.5: Autopilot Operation Check for instructions)
For airplanes equipped with the Yaw Damper function:
•Use of the Yaw Damper function during takeoff and landing is prohibited.

4 Normal Operations
4.1 General
Although operation of the primary functions of the SkyView HDX system is intuitive, it does
require a reasonable degree of familiarity to utilize all its functions without compromising
attention to other flying tasks. Users are encouraged to read the SkyView Pilot's User Guide
thoroughly before flight and to take advantage of the training videos available on
youtube.com/DynonAvionics.
Knobs and Buttons
Knobs are located on the left and right sides of the display. They can be rotated both directions
and pushed. The current knob function is indicated by the "soft" label above the knob. Knob
function is contextual and can change when the contents of the screen are changed by the pilot
(see Figure 1).
Eight buttons are located across the bottom of each display. The area immediately above the
buttons is the Main Menu, which shows "soft" labels that identify the function of each button.
Buttons have different functions depending on the information being shown on the display. The
labels for each button on the Main Menu will change accordingly (see Figure 1).

Touch Controls
SkyView HDX displays contain touchscreen functionality. Touching various items on the display
allows for the item to be selected and the value adjusted. For example, touching the HSI data
source allows for alternate sources to be selected.
Pilot-selectable choices for the layout of each screen can be selected by pressing DISPLAY
button on Main Menu. This allows the pilot to choose whether a display should show PFD, Map,
or Engine information, or some combination thereof.
See Figure 2 for details for the touchable screen areas of main flight functions. Additionally, the
Timer function has touchscreen control, and if a compatible NAV device is connected, the
Course (CRS) functions as well.

Synthetic Vision
Synthetic Vision can be turned on or off by pressing the MENU button on the Main Menu,
touching the PFD TOOLS screen icon, and then touching the SYNVIS screen icon. A green
highlight on the SYNVIS icon means it is turned on. No highlight means it is turned off.
