Slip/skid ball
The slip/skid ball works much like a standard mechanical gauge. It is a visual representation of lateral
acceleration. If the ball is within the two vertical lines, then you are in coordinated flight.
Altimeter setting display
The current altimeter setting is displayed at the bottom right of the screen below the altitude tape. The value
is shown in either inches of Mercury or millibars depending on your preference set in the BARO menu.
