7.4.5 Flight Direction Indicator

The upper portion of the AI can be configured to display direction of flight
in the form of either non-slaved DG (non-slaved heading), magnetometer
aided, or GPS track.

Both modes support a magenta heading bug, and the GPS track mode
supports a green bearing-to indicator. The heading bug is not interfaced
to the autopilot and is for reference only.

If no GPS is detected, an amber “NO GPS” will be displayed.

If either the heading bug or the bearing to bug are off the left or right sides
of the screen, a colored arrow will show the shortest-turn direction to the
corresponding bug. To align the DG bug to current heading, select DG
bug, push and hold center rotary knob.

7.4.6 Barometric Corrected Altitude Indicator

Barometric corrected altitude (BCA) can be configured for display on the
right side of the screen and shows the barometric altitude in feet. When
this field is configured for altitude display, the lower right field will be
locked to the barometric setting and cannot be modified to display a
different parameter.
