There are two reasons to have more than one Display: real estate and redundancy.
Up to four displays can be networked together. It's true that just one display can
show everything, namely the Primary Flight Display (PFD), Moving Map, and Engine
Monitoring. However, adding a second display allows both to be dedicated for specific
purposes. For example, the left display could show the PFD while the right display
shows the Moving Map and Engine Monitor. In the unlikely event of a display failure,
the remaining display can still show all data.
One SV-ADAHRS-200 will provide flight data for up to four Displays. However, you
can add one or more SV-ADAHRS-201s in order to provide redundancy. When connected
by the SkyView Network, the primary ADAHRS will provide flight data to every Display.
In the unlikely event of ADAHRS failure, the secondary or tertiary ADAHRS will provide
flight data to every display.
A remote-mounted SkyView Mode-S transponder saves panel space with control and annunciation appearing
on the SkyView displays. There are two models: the SV-XPNDR-261 for high performance
aircraft, and the SV-XPNDR-262 for aircraft flying less than 15,000' and 175 Knots.
The only difference between the two is the output power. Both add TIS traffic information,
which graphically shows other aircraft position, altitude and trajectory in standard
TCAS 1 format (TIS traffic is only available in the U.S. in Class B and C
airspace with radar coverage). Note: The FAA ADS-B requirements specify the higher power Class 1 transponder. For U.S. customers, we recommend only the Class 1 SV-XPNDR-261. Full ADS-B Out compliance will require that a TSO-C146A GPS (WAAS) be connected.
The SV-ARINC-429 makes SkyView compatible with certified GPS receivers, such as
the Garmin 430/530. If you have one of these GPS receivers, you should purchase
the SV-ARINC-429 Module. It mounts within the avionics bay, and does not use any
Each Display has two D9 Network Ports. Each Module has a single D9 Network Port.
A cable is typically required between two Displays, between a Display and an ADAHRS
Module, and between a Display and an EMS Module. SkyView Network Cables are made
of aircraft quality Tefzel wires and come in a variety of lengths. The first two
have D9 connectors on both ends. The latter five have a D9 connector on one end,
and on the other end pins are pre-crimped to the wires. Once the cables are routed
through the aircraft, the second D9 connector can be easily affixed to the pins.
Also offered is a Network Hub, SV-NET-HUB. This 5-port hub allows a complete
system to be easily wired using the cables above. The SkyView Network is a true
network, and connections can made at any location. Redundancy is assured through
duplicate network and power wires in each 9-wire cable. There are two ports on the
back of each Display, that are electrically connected to each other and isolated
from the Display electronics itself. So even if a Display were to be turned off
for any reason, the two network ports on the back are still communicating with each
