4.3.13. Track Indicator
When congured with a GPS that provides ground track data, a blue track indicator
diamond is displayed on the compass scale to indicate the aircraft’s ground track.
This indicator may be used to compensate for wind drift during ight (Figures 4-91
and 4-92). The track marker is removed from the display when ground track data is
unavailable or invalid.
4.4. Lateral and Vertical Deviation Indicator
In addition to the CDI in the lower display, separate displays of lateral and vertical
deviation information are shown in the upper display area during instrument
approaches. A Lateral Deviation Indicator (LDI) and a Vertical Deviation Indicator (VDI)
(Figure 4-93) will automatically appear, depending on the operating mode of the
selected navigation sensor and the validity of the associated signal, described below.
