Loss of External Power with Backup Battery Connected

If external power is lost to a display that is connected to a backup battery, it will either stay on

for an additional 30 seconds or stay on indefinitely depending on whether or not the aircraft is

in flight. This feature minimizes backup battery discharge when on the ground and

master/external power is shut off normally while simultaneously reducing pilot workload during

an actual in-flight power loss.

If the aircraft is not in flight, SkyView displays the message “POWERING DOWN IN xx SECONDS”

while counting down from 30 seconds. During this countdown, the menu displays the buttons

STAY ON and PWR OFF at the bottom of the screen. Press PWR OFF to turn off the SkyView

display immediately. Press STAY ON to keep the SkyView display on via the connected backup

battery. If STAY ON is pressed, the display will continue to use the backup battery to power

itself until the battery’s charge is depleted or the display is turned off manually pressing and

holding button 1. Finally, if neither button is pressed before the countdown expires, the display

will automatically turn off after 30 seconds to conserve the backup battery charge.

If the aircraft is in flight, SkyView displays the message “AIRCRAFT POWER LOST” with no

additional count down. This ensures that active pilot action is required to turn off a display

when power is lost in-flight and backup battery power is available. The STAY ON and PWR OFF

buttons are still offered, but the display will stay on indefinitely unless PWR OFF is pressed.
