3 SkyView HDX System Overview
A Skyview HDX System is an integrated Electronic Flight Instrument System (EFIS) that
aggregates air, engine, traffic, and navigation information for display to the pilot. The information
is presented on a primary SkyView HDX display, which is an LCD touchscreen with mechanical
knobs and buttons. A primary SkyView HDX display always presents a Primary Flight Display
(PFD). It can also present a Moving Map and Engine Monitoring System (EMS) information.
Subsystems, such as an Autopilot system also access this data to perform their functions. A
SkyView HDX display also presents voice aural annunciations and text messages that alert the
pilot to exceptional conditions, such as departures from desired altitudes or exceeding engine
parameter limits.
When an optional secondary SkyView HDX display is installed, the Skyview HDX System is
referred to as Multi-functional Display (MFD) system. An MFD can present any combination of
PFD, Moving Map, or EMS information in various layouts on the display screen. An MFD can
also function as a backup display should the primary display fail.
Air data and airplane motion information is collected by the Air Data Attitude Heading Reference
System (ADAHRS) module. Engine, fuel, and electrical system information is collected by the
EMS module. Navigation information is provided by a GPS antenna/receiver, as well as
integrated third-party NAV devices. Traffic data is provided by an Automatic Dependent
Surveillance Broadcast (ADS-B) IN receiver. ADS-B OUT capability is provided by the NAV
source and a transponder. The GPS antenna/receiver, ADS-B IN receiver, and transponder
connect to the SkyView HDX System using RS-232 serial communications. All serial ports have
configurable baud rates and data formats for use as general-purpose inputs and outputs.
A SkyView HDX display communicates with SkyView HDX System components via a proprietary
network. The SkyView HDX Network is a modern, multidrop serial network. SkyView HDX
Network wiring is electrically common between all SkyView HDX System components.
Connections to the SkyView HDX Network are made with unique network cables, hubs, splitters,
and connectors on the components. SkyView HDX System components include the ADAHRS
module, remote magnetometer, EMS module, Aeronautical Radio Incorporated (ARINC) 429
module, Autopilot servos, and accompanying control panels and buttons.
See Figure 1 and Figure 2 for a graphical representation of a SkyView HDX System.

4 Functional Description and Operation
This section provides an overview of the major functions and operation of a SkyView HDX
System.
4.1 SkyView HDX Displays
SkyView HDX displays are multi-functional, high-definition, LCD color displays that present
integrated Primary Flight Information (PFI), NAV/GPS information, Moving Map, COM radio
information and control, Transponder information and control, ADS-B IN and OUT, Engine
Monitoring, and Autopilot information and control.
SkyView HDX displays are available in two sizes:
•the SV-HDX1100 is a 10.1-inch, 1280 x 800-pixel display,
•the SV-HDX800 is a 7.1-inch, 1280 x 800-pixel display.
The displays utilize backlighting technology for increased lifespan, more uniform brightness,
superior dimmability, and reduced power consumption. Up to three SkyView HDX displays, in
any combination of the two sizes, can be installed in the airplane’s instrument panels.
Figure 4 shows the front of a 10" display (SV-HDX1100) and its important parts. (The figure is
also applicable for the SV-HDX800.)
Figure 4: SkyView HDX Display (SV-HDX1100 shown)
The structure surrounding the lighted LCD screen is referred to as the bezel. All tactile controls
for the system are located on the tilted shelf at the bottom of the bezel. Buttons, knobs, and an
integrated light sensor are located on the bezel. User interaction takes place via two knobs with
integrated buttons, eight buttons along the bottom of the bezel, and via tactile pressing on the
screen itself. The light sensor is used for automatic screen brightness control.

Page | 18
SkyView HDX System General Maintenance Manual, Revision F
SkyView HDX display contains three main screen regions, described from top to bottom:
•The Top Bar (i.e., Info Bar) is configurable and presents important airplane information,
including clock time or a timer (when running), Autopilot status, Backup Battery status,
COM radio frequency, and Transponder status.
•The main portion of the screen is configurable and presents the PFD, Moving Map, and
EMS data, configuration information, menu and feature control pages, and many system
messages.
• The Main Menu (i.e., Bottom Bar) is displayed once the system is fully powered-on.
It presents knob and button labels in a menu arrangement. Knob and button
functionality are contextually-based and determined by what is presented on the screen.
The labels show the user the current function.
All SkyView HDX displays have touchscreen functionality on the PFD, Moving Map, and Info
Bar. Functions are selected and values adjusted by touching points on the screen. For example,
touching the HSI Source Selector (#9 in Figure 5) allows a different source to be selected to
present the HSI.
Selectable configurations for screen layouts are selected by pressing the display softkey. This
allows the pilot to choose whether adisplay should show PFD, Moving Map, or EMS information,
or a combination thereof.

4.3 Buttons and Knobs
The buttons and knobs on a SkyView HDX display are used for various functions, including
powering the unit ON and OFF, accessing and navigating menus, selecting or activating
features, and adjusting values.
Buttons generally require a single action (i.e., momentarily press). Pressing the button will
provide a distinct tactile click response to the pilot. The click occurs when the button is fully
pressed, but the action does not occur until the button is released. When a button is pressed in
this manner, a function or action denoted by the label above the button is invoked. Button
labels are contextual and may change dependent on menus and feature control pages the
pilotselects.
A button has a function if a label displays above it. If there is no label, then no function is
available. Some buttons have additional behavior when the button is pressed and held down for
two seconds. An example is Button #1. When you press-and-hold Button #1, the SkyView HDX
display willpower ON/OFF. Additional press-and-hold behaviors for other buttons are described
in the SkyView HDX Airplane Flight Manual Supplement document.
Knobs can be rotated in both directions and pushed. The current knob function is indicated by
the label above the knob. Knob function is contextual and can change when the contents of the
screen is changed by the pilot.
Figure 7: Knob Rotation and Button Push Actions
On some screen pages with both vertical lists and a horizontal group of tabs, one or both knobs
can exhibit a push and rotate behavior which controls horizontal scrolling of the cursor across
rows and columns on some menus.
