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 contains information related to operating the optional Autopilot. Not every
airplane is approved to be equipped with the SkyView HDX Autopilot system.

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 flightand to take advantageof the training videos available on Dynon Avionics
YouTube channel.
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).
Figure 1: SkyView HDX Hardware Controls

Page | 4-2
SkyView Airplane Flight Manual Supplement, Rev N, 10/23/2020
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.
Figure 2: HDX Touch Controls
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.
