SkyView HDX Pilot’s User Guide – Revision B 11-1
11. Operations if Avionics Power is Lost / SV-BAT-320 Backup Battery
If, due to loss of Avionics power, your SkyView HDX display is powered solely by the
SV-BAT-320 Backup Battery, it is advised that you land as soon as possible.
Each SkyView HDX display can be connected to one SV-BAT-320. When an SV-BAT-320 is new
and fully charged, it provides sufficient power to operate a SkyView HDX display and connected
devices on SkyView Network for at least 60 minutes.
Loss of Avionics Power While In Flight
If a SkyView HDX display with an installed SV-BAT-320 is in flight, and Avionics power is lost, the
SkyView HDX will display:
AIRCRAFT POWER LOST
and the MAIN MENU will change to display two buttons:
STAY ON
POWER OFF
When this message is displayed, the SkyView HDX display is now receiving power solely from
the SV-BAT-320 and will operate until the SV-BAT-320’s available power is depleted.
To maximize operational time when the SkyView HDX display is receiving power
solely from the SV-BAT-320, the maximum display brightness of SkyView HDX
display is automatically reduced very slightly.
If neither button is pushed, the SkyView HDX display and SkyView system will continue to
operate. However, the AIRCRAFT POWER LOST message will continue to be displayed.
To continue “normal” operations with the SkyView HDX display after the AIRCRAFT POWER
LOST message appears, push the STAY ON button. As soon as the STAY ON button is pushed,
the AIRCRAFT POWER LOST message will be suppressed and the normal Main Menu will
reappear. The SkyView HDX display and SkyView system will operate until the SV-BAT-320’s
available power is depleted.
When the SkyView HDX display and SkyView system are powered solely by the SV-
BAT-320, there is no “battery gauge” grapic, “% power remaining”, “countdown
timer” displayed to provide guidance of remaining power in the SV-BAT-320.
If the POWER OFF button is pushed, the SkyView HDX display will power itself off. For example,
this might be useful if you have two SkyView HDX displays, and want to power your SkyView
system from only one display until that display’s SV-BAT-320 available power is depleted; you
can then power up the remaining SkyView HDX display on its SV-BAT-320 by pushing and
holding Button 1.
