Section 14. Primary Flight Display (PFD)
Horizontal Deviation Indicator (HDI)
The PFD displays a horizontal deviation indicator when VLOC1 or VLOC2 is
tuned to and receiving a localizer frequency.
The HDI scale provides tick marks for zero deviation, half and full scale (left,
right). The navigation source is displayed to the right of the HDI and will indicate
ILS, LOC, BCRS (back course) or FMS. A white HDI pointer indicates course
deviation; if the pointer exceeds full scale deviation, it turns amber.
