SkyView HDX Pilot’s User Guide – Revision B 1-1
1. Introduction
Thank you for purchasing the Dynon Avionics SkyView HDX system! This section provides some
important cautionary information and general usage instructions for this guide.
The printed version of this guide is in grayscale. Some figures and diagrams contain important
color information. Reference the electronic version of this guide to view it in color.
Before You Fly
We strongly recommended that you read this entire guide before attempting to use SkyView in
flight. Additionally, we encourage you to spend time on the ground familiarizing yourself with
the operation of the system. While first learning to use the system in the air, we recommend
you have a backup pilot with you in the aircraft. Finally, we encourage you to keep this guide 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. In a flying situation, it is your responsibility to use
the system and the guide prudently.
Warning
Dynon Avionics’ products incorporate a variety of precise, sensitive electronics. SkyView
products do not contain any field/user-serviceable parts. Units found to have been taken apart
may not be eligible for repair under warranty. Additionally, once a Dynon Avionics unit is
opened up, it is not considered airworthy and must be serviced at the factory.
Video Training
This guide is intended to familiarize a new SkyView HDX pilot with the basics of operating a
SkyView system. No printed (or electronic) guide such as this can substitute for “seeing it in
action”, and thus Dynon Avionics aims to provide various instructional videos, including a
complete SkyView operations course –see www.dynonavionics.com/videos. These videos help
new owners quickly learn the basics so they can safely start flying with the system. Also, current
SkyView owners can gain in-depth knowledge of many of the more advanced or complex
features.
About this Guide
This guide helps you configure and get acquainted with SkyView HDX’s many functions and
facilitates quick access to vital information. If you have a SkyView SE, or SkyView Classic/Touch
system, this is not the correct guide for those products. Each has its own dedicated guide: the
SkyView SE Pilot’s User Guide, and the SkyView Pilot’s User Guide, available at
docs.dynonavionics.com. For detailed technical and installation information, refer to the
SkyView Classic / SE / HDX System Installation Guide, also available at docs.dynonavionics.com.
This guide is revised, at a minimum, several times per year, usually coinciding with the release
of a new version of SkyView firmware, or introduction of new SkyView-related products from

Introduction
1-2 SkyView HDX Pilot’s User Guide – Revision B
Dynon Avionics or partner companies. This revision reflects the features available as part of the
firmware version stated on the cover page. If your SkyView HDX system currently has an earlier
firmware version, some features may not be available for use on your SkyView system (until
you update its firmware).
Printing This Guide
To reduce waste and confusion resulting from outdated information in print, Dynon Avionics no
longer provides this guide in printed form. The latest, most up-to-date and most complete
version of this guide –and all Dynon Avionics documentation –is always available at
docs.dynonavionics.com. Rather than printing this guide on a home printer (typically, with
relatively expensive inkjet printing) we recommend that you take the PDF file of this guide to be
printed at a large office supply retailer that provides printing services. The statement on the
cover of this guide: Permission to print this document is granted to third parties. should be
sufficient permission to do so.
It is also handy to have the electronic version on your tablet computer as reference as you can
perform keyword searches, and the electronic version includes figures and diagrams that
contain important color information. For example, we have found that the free “iBooks”
application that can be installed on Apple iPad tablet computers can import this guide’s PDF file
for easy reference. Similar PDF reader applications are available for Android devices.
In the electronic (.PDF) version of this guide, page and section references in the Table of
Contents and elsewhere act as hyperlinks taking you to the relevant location in the guide. The
latest electronic version (.PDF) of this guide may be downloaded from our website at
docs.dynonavionics.com.
This guide discusses the most common operation scenarios. If you have an operational issue
that is not discussed in this guide, you can find additional operational information on Dynon
Avionics’ internet sites:

This icon denotes a helpful tip.

SkyView HDX Pilot’s User Guide – Revision B 2-1
2. SkyView HDX System Overview
This section provides a general overview of the various parts of SkyView HDX 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 units. It should not be used for diagnostic or reparative
work.
Dynon Avionics provides periodic firmware updates that enable new functionality.
Reference the SkyView Classic / SE / HDX System Installation Guide for instructions
on how to update firmware on SkyView equipment.
Displays –SV-HDX800 and SV-HDX1100
This guide refers to the SV-HDX800 and SV-HDX1100 as displays.
Functions
Each SkyView HDX display can act as a Primary Flight Display (PFD) with Synthetic Vision, an
Engine Monitoring System (EMS), and a Moving Map in a variety of customizable screen
layouts. Data is sourced from various connected modules and devices. Subsequent sections in
this guide address PFD, Engine, and Moving Map functions in more detail.
Power
SkyView displays require between 10 and 30 volts DC for operation. See the SkyView Classic /
SkyView SE / SkyView HDX System Installation Guide for details on power consumption.
SkyView systems have robust power protection that allows the SkyView system to be powered
on during engine start.
SV-BAT-320 Backup Battery
If an SV-BAT-320 Backup Battery is installed, a SkyView HDX display can be powered up without
energizing the avionics bus, such as to monitor engine parameters during engine start. If
avionics power is lost in flight, a properly operating SV-BAT-320 can provide power to a SkyView
HDX display, SkyView Network modules, and an SV-GPS-250/2020 GPS receiver for at least 60
minutes. The SV-BAT-320 is automatically (re)charged by the SkyView HDX display during flight.
Refer to Section 10 of this manual for more information about use of the SV-BAT-320 and
operation when using the SV-BAT-320 to power the SkyView system.
Note that the following Dynon Avionics SkyView units are not powered by the
SkyView HDX display / SV-BAT-320, and thus these units will not function if ship’s
power / avionics power is lost in flight:
•SkyView servos –Autopilot (AP)
•SV-COM-C25 / SV-COM-X83 COM Radio
•SV-ADSB-470/472 ADS-B Receiver
•SV-XPNDR-261 / SV-XPNDR-262 Transponder

SkyView HDX System Overview
2-2 SkyView HDX Pilot’s User Guide – Revision B
SkyView Network
SkyView modules such as the SV-ADAHRS-20X (provides flight instrument data), SV-EMS-
220/221 (provides engine instrument data), SV-ARINC-429 (for communication with IFR
GPS/NAV/COM devices), SV-COM-C25/X83 (COM Radio), SV-KNOB-PANEL, SV-AP-PANEL and
Autopilot servos use Dynon Avionics’ redundant SkyView Network to communicate with
SkyView HDX displays.
The SkyView Network is designed to continue to work properly in the event of wiring or module
faults by utilizing multiple power pathways and a redundant data network. In fact, SkyView can
annunciate wiring issues as they are discovered, often while preserving full system functionality
until troubleshooting can be performed on the ground. These alerts are presented in SkyView
HDX’s alerting system, which is described in a later section of this guide.
RS-232 Serial
SkyView HDX displays have five RS-232 serial ports for connection to compatible equipment.
SkyView modules which use RS-232 serial communications include the SV-GPS-250/2020 GPS
receivers, SV-ADSB-470/472 ADS-B receiver, and SV-XPNDR-261/262 transponders. All serial
ports are wired into the SkyView Display Harness (SV-HARNESS-D37). All serial ports have
configurable baud rates and data formats for use as general purpose inputs and outputs.
USB
SkyView HDX displays have three USB ports. Two are built into the back of the display and one
is wired into the SkyView Display Harness for convenience. USB ports are used for transferring
files (firmware updates and backups, database updates, configuration file uploads and
downloads), the optional SkyView Wi-Fi Adapter, and optional SkyView Video Adapter. These
devices must be plugged into the display before power on and remain plugged in for the full
flight. Reference the SkyView Classic / SE / HDX System Installation Guide for instructions on
how to use the USB ports for the operations mentioned above.
When using a USB flash drive with a computer file system, only one USB flash drive is
recognized at one time by the SkyView HDX display. If a second USB flash drive is plugged in,
the second one will not be recognized by the display until the first USB flash drive is removed,
and the second USB flash drive is re-inserted.
USB Flash Drive
Each SkyView HDX display ships with a Dynon Avionics labeled USB flash drive; however, there
is nothing unique about this USB flash drive (other than the label). Any appropriate size USB
flash drive may be used with SkyView HDX. If Procedure Charts, Airport Diagrams and Enroute
Charts are used, a USB flash drive with those database files must reside in one of the display’s
three USB ports while in operation (the files are not transferred to SkyView HDX’s internal
storage).

SkyView HDX System Overview
SkyView HDX Pilot’s User Guide – Revision B 2-3
SkyView HDX Displays
The SV-HDX800 uses a 7-inch, 1280 x 800 pixel, 1200+ nit TFT active matrix capacitive multi-
touch LCD screen. The SV-HDX1100 display is a 10.1-inch, 1280 x 800 pixel, 1350+ nit TFT active
matrix capacitive multi-touch LCD screen. SkyView displays utilize LED backlighting technology
for increased lifespan, more uniform brightness, superior dimmability, and reduced power
consumption.
SkyView HDX displays are capable of automatic screen backlight level management. Reference
the SkyView Classic / SE / HDX System Installation Guide for instructions on how to enable this
feature.
Displays Are Synchronized
If you have multiple SkyView HDX displays in your aircraft, actions such as setting BARO, BUGS,
engaging the Autopilot, or acknowledging warnings only need to be performed on one display
(or control panel) and that action is synchronized throughout the SkyView HDX system.
Some settings such as individual screen layout and map range level are deliberately not
synchronized between multiple SkyView HDX displays.
Buttons, Knobs and Touch Interface
User interaction takes place via the two knobs, two buttons integrated into the knobs, and
eight buttons along the bottom of the SkyView HDX display’s bezel and via touch gestures on
the display screen itself.
Data Logging
SkyView HDX displays record and store flight information in several datalogs which can be
exported for analysis by the owner, and a high-resolution datalog which can is used by Dynon
Avionics for troubleshooting. To configure the data recording rate and other parameters of the
datalog, refer to the SkyView Classic / SE / HDX System Installation Guide.
Synthetic Vision (SynVis)
When valid GPS data is available, and a high-resolution terrain database for the appropriate
region is loaded, the PFD features integrated Synthetic Vision. Synthetic Vision displays the
terrain directly ahead of the aircraft. Terrain is graphically represented in sectional chart color
variations which represent topographical elevations and water features. Terrain is textured
with a subtle checkerboard pattern to aid in identifying aircraft movement.
GPS Moving Map and VFR GPS Navigator
SkyView HDX features a robust GPS moving map and VFR GPS navigator. Aviation and Obstacle
data can be displayed, as well as VFR and IFR enroute charts, procedure charts (plates), and
airport diagrams. Go to http://dynonavionics.com/downloads to find links to the various
sources of aviation / obstacle data and chart data.

SkyView HDX System Overview
2-4 SkyView HDX Pilot’s User Guide – Revision B
Flight Data Modules –SV-ADAHRS-200, SV-ADAHRS-201, and SV-MAG-236
This guide uses SV-ADAHRS-20X to refer to both the SV-ADAHRS-200 and the SV-
ADAHRS-201. The SV-ADAHRS-200 and SV-ADAHRS-201 are identical in
performance and are designed to work together as a redundant ADAHRS solution.
An SV-ADAHRS-200 must be installed in your SkyView system use an SV-ADAHRS-
201.
The primary flight instruments on your SkyView PFD are generated using a group of calibrated
sensors built into the SV-ADAHRS-20X ADAHRS module. All sensors 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.
Due to the sensitivity of the SkyView ADAHRS to magnetic interference, some aircraft
installations are better served by mounting the SV-ADAHRS-20X within the specified center of
gravity box and installing an SV-MAG-236 Remote Magnetometer well away from any dynamic
magnetic interference –and possibly outside the center of gravity box specified for the
ADAHRS. If an SV-MAG-236 is installed, its magnetometer provides magnetic heading data to
the system, and data from the integrated magnetometer(s) in the SV-ADAHRS-20X are
disregarded.
Table 2 describes which inputs and sensors are used within the ADAHRS module to generate
the different displayed instruments.

Attitude Calculation
The SkyView artificial horizon display (attitude) is generated via a complex algorithm using a
multitude of sensors as described in Table 2. In normal operation SkyView uses airspeed to
provide superior attitude accuracy. Should airspeed become unavailable due to inadvertent
blockage of the pitot system, GPS ground speed will be used as an attitude aid. GPS ASSIST will
be annunciated on the PFD when this mode is in effect.
Compass Accuracy Effects on Synthetic Vision, Map Performance, and Autopilot
It is critical that the magnetic heading be as accurate as possible for optimal Synthetic Vision
and Moving Map performance. The SV-ADAHRS-20X –and SV-MAG-236 if included in the
system –must be installed correctly, calibrated, and operating well in all attitudes. However, it
is important to note that magnetic heading is not used to aid attitude determination under any
circumstance.
GPS Receivers –SV-GPS-250 and SV-GPS-2020
The SV-GPS-250 and SV-GPS-2020 GPS modules are externally mounted GPS receivers designed
specifically for use with SkyView systems. Both modules are powered by the SkyView HDX
display (and thus will provide position updates when the SkyView HDX display is operating on
battery backup power). Each module outputs GPS data to SkyView in NMEA format and
automatically sets the time on the SkyView HDX display.
To improve positional accuracy, both the SV-GPS-250 and the SV-GPS-2020 receive
Wide Area Augmentation System (WAAS) GPS correction signals (where WAAS is
available). The ability to receive WAAS GPS correction signals does not allow the SV-
GPS-250 or SV-GPS-2020 to be used as a primary navigation source in an IFR
environment where a TSO’d WAAS GPS may be required.
The SV-GPS-2020 became available in early 2016 and provides position updates 4x/second. In
the US, the SV-GPS-2020 GPS receiver is qualified to serve as the required GPS position source
for purposes of meeting the FAA 2020 ADS-B Out mandate. It must be installed in a SkyView
system together with the SV-XPNDR-261 Class 1 Mode-S transponder (see below for more
information) for full ADS-B Out compliance.

Engine Data Modules –SV-EMS-220 and SV-EMS-221
The engine gauges on your SkyView Engine Page are generated from the data acquired by the
SV-EMS-220 or SV-EMS-221 Engine Monitoring module and their connected sensors. These
modules support popular four and six-cylinder engine installations and can measure a variety of
engine and environmental parameters such as RPM, manifold pressure, oil temperature and
pressure, exhaust gas temperature (EGT), cylinder head temperature (CHT), fuel levels for
multiple tanks, voltage, current, fuel pressure, fuel flow, carburetor air temperature, coolant
pressure and temperature, flap and trim potentiometers, external contacts, and general
purpose temperature sensors.
Autopilot –Servos
Dynon Avionics SV32, SV42, and SV52 servos enable the operation of SkyView’s integrated
autopilot system. Refer to the SkyView Classic / SE / HDX System Installation Guide for more
information about Dynon Avionics autopilot servos. SkyView HDX can only control Dynon
Avionics servos.
Autopilot Control Panel –SV-AP-PANEL
The SV-AP-PANEL is an optional panel-mounted module that affords dedicated controls for the
SkyView AP’s Expert Mode. The SV-AP-PANEL includes dedicated buttons for engaging the
Flight Director, Autopilot, and all modes including setting up fully-coupled approaches, VNAV,
IAS Hold, and mode sequencing (provided that the necessary IFR navigation sources are
installed in the aircraft). It also has a LEVEL button to immediately return the aircraft to straight
and level flight.
Auto-trim
A secondary function of the SV-AP-PANEL is that it can control one or two electric trim control
motors (replaces a conventional “relay deck”). If this function is installed, the SkyView HDX
Autopilot, when engaged, can also provide automatic trim control –Auto-trim.
Transponders –SV-XPNDR-261 and SV-XPNDR-262
The SV-XPNDR-261 (Class 1) and SV-XPNDR-262 (Class 2) are TSO’d remote mounted Mode-S
transponder modules that, in addition to their transponder capability, contain ADS-B Out
capability via 1090 ES, and TIS traffic input capability (US Only). Note: Only the Class 1 SV-
XPNDR-261 meets the 2020 mandate for ADS-B Out.
ADS-B Receiver –SV-ADSB-470/472
The SV-ADSB-470 and SV-ADSB-472 receive traffic and weather information from the Automatic
Dependent Surveillance –Broadcast (ADS-B) system. ADS-B data allows integrated traffic and
NEXRAD weather data to be displayed on your SkyView HDX display. The SV-ADSB-470 is a 978
MHz (UAT Band) receiver, while the SV-ADSB-472 is a dual band 978 MHz/1090 MHz receiver.
