2-4 Normal Startup Sequence
In dual Air Data and Attitude Reference System (ADAHRS)
equipped systems, each IFD ADAHRS aligns independently.
Therefore, it is recommended that each ADAHRS is verified to
have aligned prior to taxi or takeoff by either checking the PFD
tab of each IFD, or noting the CAS messages or checking the
Sensor tab of the SYS page. In a DFC100-equipped aircraft, the
top strip of the PFD pages will display “AUTOPILOT INOP AHRS
ALIGNING” until all
AHRS are aligned.
In the event that one or more of the displays has:
• An out of date data (e.g. expired Nav data, expired
Charts data, expired Obstacle data) or
• A software mismatch between the IFDs
an information screen is displayed in place of the Initial Fuel view
Engine tab. This behavior is covered in more detail in the System
Alerts section of this guide.
COOL FEATURE
Home and Persisted Tabs As soon as the pilot has
made the initial fuel entry, all tabs become
“persisted”. This means that the last tab selected on
any given page will be retained, even if a different
page is selected. For example, if the Split Map-FPL
tab of the FMS Page Function Key is selected and
then the SYS Page Function Key is selected, when
the FMS Page Function Key is pressed again, the
Map-FPL tab will still be the active tab. Each Page
Function Key also has a Home tab that is
automatically accessed if the Page Function Key is
pressed and held for a few seconds. In this case, no
matter what the active tab was, the page home tab
will become the new active tab and the displays
may re-format a little. Definitions of the page home
tabs can be found in the SYS appendix.
