An
integral
slip indicator is provided and may replace the mechanical slip
indicator mounted in the bezel. The slip indicator is a rectangle just below
the heading pointer that moves left and right to indicate the lateral
acceleration sensed by the AHRS in the same manner as the ball in a
mechanical slip indicator.
The integral slip indicator is responsive to lateral
(Y-axis) G-force (the slip indicator is the white rectangular part of the
heading pointer) and is damped, so it approximately matches a
conventional glass vial indicator.
When the AHRS is in DG mode, the DG symbol appears as
shown here.
