ND Approach Mode – Range Marks – Track Line:
In approach mode, the ND
shows a glideslope deviation
indicator and a localizer course
deviation indicator (CDI)
referring to the ILS course
entered on the FMC NAV
RADIO page. The magenta
deviation bar is filled when it is
2.3 dots from the center.
Track line & range marks
The track line is displayed in all
ND modes except for the plan
mode. When the ND range is
changed, the system revalidates
the scales of the FMC inputs
and of the WXR or terrain
inputs for a fraction of a second:
during this process the range
indication is blank.
Optionally, in approach
mode, the track line is
replaced by a triangleshaped
track pointer.
