NOTE:
Refer to the Appendices for AHRS initialization bank angle limitations.

See the Appendices for additional information regarding system-specific annunciations and alerts.
NOTE:
See the Pilot’s Operating Handbook (POH) for specific procedures concerning avionics power
application and emergency power supply operation.
The Perspective
™
system is integrated with the aircraft electrical system and receives power directly from
electrical busses. The PFD, MFD and supporting sub-systems include both power-on and continuous built-in
test features that exercise the processor, RAM, ROM, external inputs and outputs to provide safe operation.
During system initialization, test annunciations are displayed, as shown in Figure 1-17. All system annunciations
should disappear typically within one minute of power-up. Upon power-up, key annunciator lights also become
momentarily illuminated on the audio panels, the control units and the display bezels.
On the PFD, the AHRS begins to initialize and displays ‘AHRS ALIGN: Keep Wings Level’. The AHRS should
display valid attitude and heading fields typically within one minute of power-up. The AHRS can align itself both
while taxiing and during level flight.
When the MFD powers up (Figure 1-18), the MFD Power-up Page displays the following information:
• System version
• Copyright
• Land database name and version
• Safe Taxi database information
• Terrain database name and version
• Obstacle database name and version
• Navigation database name, version, and effective
dates
• Airport Directory name, version and effective dates
• FliteCharts/ChartView database information
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 the Navigation Map Page is displayed upon
pressing the key a second time. When the system has acquired a sufficient number of satellites to determine a
position, the aircraft’s current position is shown on the Navigation Map Page.
