General System Installation Tips
Aircraft construction involves a variety of processes that create debris that can
damage Dynon Avionics components. Metalwork, in particular, will produce
metallic shavings and dust that may damage or destroy the electronics in Dynon
Avionics products if they are contaminated with this debris. Care should be taken
to ensure that Dynon Products are kept away from aircraft construction debris.
Damaged caused by the introduction outside particulates will not be repaired
under warranty.
Do not physically modify Dynon SkyView displays or modules in any way that is not
specified in this manual. Damage caused to Dynon products due to physical
modifications will not be repaired under warranty.
SkyView Can Be On During Engine Start
SkyView units incorporate robust power protection that allows them to be powered on during
engine start for full engine monitoring. SkyView displays require a minimum of 10V, and during
engine start, it’s common for the electrical system to temporarily drop below 10V. If an SV-BAT-
320 backup battery is not installed, SkyView may shut off / reboot. If you wish to monitor your
engine prior to engine start, an SV-BAT-320 backup battery should be installed so that the
SkyView display can switch to the SV-BAT-320 when its power inputs are not receiving at least
10V. The SkyView display will switch from SV-BAT-320 to ship’s power when its power inputs
receive voltage above 10V.
Installing SkyView in an IFR-Equipped Aircraft
If you are equipping an aircraft that is capable of being flown in IFR/IMC conditions, Dynon
Avionics makes the following recommendations:
The entirety of the instrument panel and supporting avionics systems and instrumentation
should be designed so that the display of information essential for continued safe flight and
landing will remain available to the pilot after any single failure or probable combination of
failures. In other words, a usable "partial-panel" of primary flight instruments should be
preserved in the event of the failure of a SkyView display, systems that support it, or other
instruments in the aircraft.
This level of redundancy can be obtained in different ways. For example, one could utilize
multiple SkyView displays (with SV-BAT-320 backup batteries attached) including multiple
ADAHRS units connected to protect against the failure of any single display, ADAHRS, or the
electrical system. Flight instrument redundancy could also be preserved by using other separate
and independent systems such as the Dynon EFIS-D6. Some builders may elect to combine
SkyView with other more conventional “steam” gauges such as mechanical airspeed, altitude,
and attitude indicators.
