ATTITUDE CALCULATION
The EFIS-D100 artificial horizon display (attitude) is generated via a c
Your EFIS attitude is not reliant on any single external system. It
can provide an accurate attitude - even in the event of airspeed loss
(due to icing or other blockage) - via a redundant GPS aiding source.
In normal operation the instrument uses airspeed to provide superior
attitude accuracy. If a problem develops with your airspeed reading
a properly connected and configured GPS source acts as a substitute. When in this mode the instrument continues to
provide accurate attitude. omplex algorithm using a multitude of sensors.

*If a GPS is present upon the loss of airspeed, the EFIS-D100 uses the GPS ground speed in
its attitude calculation. When in this mode, a magenta GPS ASSIST message is displayed
over the horizon and the ground speed is displayed below the IAS indicator (as shown at
right). If the connectivity with the GPS fails while in GPS assist mode, the attitude continues
to be displayed, using the last known GPS ground speed as a reference. This mode is flagged
on the horizon with a yellow CROSS CHECK ATTITUDE message. In the very rare case that
