917.7.4 RSM GPS USAGE
The EFD1000/500 System includes a non-certified GPS receiver. This GPS can provide positioning
data when all other approved sources of GPS data have failed.
Position data from the RSM GPS will only become available for use following a loss of position
information from all other connected GPS system(s). When the RSM GPS is in use, the current
flight plan leg will be shown in white rather than magenta, and a message is presented limiting the
RSM GPS to EMERGENCY USE ONLY.
917.7.5 OPERATION ON INTERNAL BATTERY
N O T E
Takeoff with aircraft voltage (as indicated on the EFD) below 12.3V is not recommended.
Each EFD1000 or EFD500 is equipped with an internal battery.
The EFD System incorporates sophisticated power logic to determine when to transition to the
internal battery. On the ground, the system will turn on and turn off with the application or removal
of aircraft power. In the air, the system will transition to battery if aircraft power is removed or
degraded. Transition thresholds and times will vary as a function of the input voltage to the display,
which can be observed via the Menu Power Settings Page.
Battery operation should be expected any time the aircraft charging system is unable to maintain
a voltage at the EFD of 12.3 V. Under these circumstances, should the aircraft dispatch the EFD
will transition to battery shortly after reaching flying speed.
