If GPS input fails, the AHRS can continue to provide attitude and heading information
to the PFD as long as magnetometer and airspeed data are available and valid.
If the magnetometer input fails, the AHRS continues to output valid attitude
information; however, the heading output on the PFD Page is flagged as invalid with
a red 'X'.
Failure of the air data input has no effect on the AHRS output while AHRS is receiving
valid GPS information. Invalid/unavailable airspeed data in addition to GPS failure
results in loss of all attitude and heading information. Likewise, loss of magnetometer
(heading) data, in combination with loss of GPS data, results in a loss of all attitude
and heading information.
If a Garmin G5 Electronic Flight Instrument is installed, it will provide a redundant
source of attitude and air data in addition to that provided by the dedicated ADAHRS
unit (GSU 25D). If the sensor source selection is AUTO and attitude or air data is
unavailable from any dedicated ADAHRS unit, the PFD will automatically revert to
displaying data from the standby display. This will be annunciated on the PFD with an
'AHRS REVERT' or 'ADC REVERT' message.

1.6 ACCESSING SYSTEM FUNCTIONALITY

MENUS

The G3X Touch has a dedicated MENU Key. Press MENU once to display a context-
sensitive list of options for the page or the dedicated PFD. Press MENU twice to
display the Main Menu.
The Page Menu allows the user to access additional features or make setting changes
which specifically relate to the currently displayed page. The menu will display 'No
Options' when there are no options for the page selected.

DATA ENTRY

Data can be entered by using the touchscreen or the knob. In some instances, such
as when entering an identifier, the G3X Touch tries to predict the desired identifier
based on the characters being entered. In this case, if the desired identifier appears,
touch Enter to confirm the entry without entering the rest of the identifier manually.
This can save the pilot from having to enter all the characters of the identifier.
