NOTE:
When operating in Demonstrator mode, the IDU is isolated from all
sensors and other IDUs. Flight plans created on an IDU are stored on that
IDU alone. To make the flight plan available on all other displays, the
following action must be taken.
While in flight mode, activate the flight plan created in the
demonstrator mode.
With crossfill enabled (in two sided systems), view active flight plan
on any other IDU and press
SAVE (L1)
to save this flight plan on
all displays.

EFIS Training Tool
In addition to the demonstrator program, the EFIS Training Tool (ETT) is
available to load on a personal computer. The ETT is compatible with 32-
or 64-bit versions of Microsoft Windows
. It serves as a multi-purpose tool
for training pilots and provides features to record and capture images. See
user guide distributed with the ETT installer for further details.

Application Software Air Mode and Ground Mode
Numerous symbology elements change behavior depending upon whether
the aircraft is on the ground (ground mode) or in flight (air mode). Mode is
determined separately from the system initialization modes. This parameter
is continuously calculated as follows:
1) With a weight on wheels/weight on ground discrete input configured,
air or ground mode is determined solely from the discrete input
position.
2) Otherwise, mode is determined as follows:
a) If airspeed is valid and AGL altitude is valid, ground mode is set
when indicated airspeed is less than 30 knots, and AGL altitude is
less than 75 feet.
b) If airspeed is invalid but AGL altitude is valid, ground mode is set
when AGL altitude is less than 75 feet.
c) Under any other circumstance, air mode is set by default.
