2.3.2 Apply System Power
The system is integrated with the aircraft electrical system and receives power directly
from electrical busses. The PFDs, MFD and supporting sub-systems include both power
on and continuous built-in test features that exercise the processor, system memory,
external inputs and outputs to provide safe operation.
During system initialization, test annunciations appear on both PFDs. All system
annunciations should disappear typically within one minute of system start. Upon start,
key annunciator lights also become momentarily illuminated on the audio panels, the
control units and the display bezels.
On the PFDs, the AHRS initializes and displays 'AHRS ALIGN: Keep Wings Level'. The
AHRS should display valid attitude and heading fields typically within one minute of
system start. The AHRS can align itself both while taxiing and during level flight.
When the MFD starts, the MFD Start Page shows the following information:
• System version
• Checklist File
• Land database name and version
• Safe Taxi database and expiration date
• Terrain database name and version
• Airport Terrain database name and version
• Obstacle database name and expiration date
• Navigation database name and expiration date
• Airport Directory name and expiration date
• FliteCharts/ChartView name and expiration date
Current database information includes the valid operating dates, cycle number and
database type.
When this information has been reviewed for currency (to ensure that no databases have
expired), the pilot is prompted to continue. Pressing the ENT Key acknowledges this
information and displays the Navigation Map (MAP) Page. When the system has
acquired enough satellites to calculate a position, the aircraft's current position is shown
on the Navigation Map Page.
