4.4.4. Course Deviation Indicator and Scale
Selected course deviation is depicted by a Course Deviation Indicator and Scale.
Deviation is indicated by positioning the Course Deviation Indicator on the Scale
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 4-37
).
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 4-38
).
4.4.5. CDI Navigation Source
When the E5 Dual EFI powers up, the default Selected CDI Navigation Source is the
last source selected. The pilot can select from any of the installed navigation sources
using the Middle Button. The EFI supports navigation information display from VHF
Omni-directional Radio Range (VOR) navaids, and Global Positioning Systems (GPS).
There can only be one GPS Nav/Com and one VHF Nav/Com systems integrated with
the E5 Dual EFI.
When integrated GPS/VLOC equipment are installed, the GPSS signal source is provided
by the associated GPS whenever the CDI navigation source is selected to either the GPS
side or the VLOC side of the integrated GPS/VLOC receiver.
