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
