SkyView Pilot’s User Guide - Revision M
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.
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 ADAHRS must be installed correctly, calibrated, and
operating well
in all attitudes
.
SV-EMS-22X
The engine gauges on your SkyView Engine Page are generated from the data acquired by the
SV-EMS-22X Engine Monitoring module and its sensors. This module supports 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. Certain configurations of the SV-EMS-22X module also support 7-cylinder
engines.
SV-GPS-250
The SV-GPS-250 GPS Receiver module is an optional externally mounted 5 Hz WAAS enabled
GPS receiver designed specifically for use with SkyView. It supplies GPS data in NMEA format
and automatically sets the time on SkyView.
The SV-GPS-250’s WAAS capability does not allow it to be used as a primary
navigation source in an IFR environment where a TSO’d WAAS GPS may be
required. It does mean that it utilizes the WAAS GPS satellite to improve its
positional accuracy compared to a non-WAAS enabled GPS.
SV-BAT-320
The SV-BAT-320 Backup Battery is an optional backup battery for use with SkyView. It can
power a typical SkyView display and most of its connected modules for at least 60 minutes in
the event of failure of the aircraft electrical system.
In the event of an electrical failure that causes SkyView to run on the SV-BAT-320, the SV-BAT-
320 supplies power to the SkyView display it is connected to, along with any connected SV-
ADAHRS-26X, SV-EMS-22X, SV-ARINC-429, and SV-GPS-250 modules. Because of higher power
requirements, the SV-BAT-320 does not power Autopilot servos, the SV-XPNDR-26X, devices
connected via a serial connection, or any other third party devices.
