corresponding to the lateral deviation value.
Course Deviation Indicator
Course Deviation Scale
The ARC CDI Compass Mode’s CDI and Scale are located at the bottom of the lower
display. The indicator is a green diamond, and the Scale is a set of four hollow, white
dots with a white index mark at the center (Figure 4-59).
When the lateral deviation exceeds the maximum displayable range of 2.5 dots, the
Deviation Indicator bar or diamond, as applicable, becomes hollow and darker (Figure
