VERTICAL DEVIATION
NOTE: The Glidepath Indicator is only shown for aircraft with GIA 63W Integrated Avionics Units when
WAAS is available.
The Vertical Deviation Indicator (VDI; Figure 2-13) uses a magenta chevron to indicate the baro-VNV vertical
deviation when Vertical Navigation (VNV) is being used; the VDI appears in conjunction with the “TOD within
1 minute” alert. Full-scale deflection (two dots) is 1000 feet. The VDI is removed from the display if vertical
deviation becomes invalid. See the Flight Management Section for details on VNV features, and refer to Section
2.2, Supplemental Flight Data, for more information about VNV indications on the PFD.
The Glideslope Indicator (Figure 2-14) appears to the left of the Altimeter whenever an ILS frequency is tuned
in the active NAV field and the heading is less than 105° from the inbound course. A green diamond acts as the
Glideslope Indicator, like a glideslope needle on a conventional indicator. If a localizer frequency is tuned and
there is no glideslope, “NO GS” is annunciated.
The glidepath is analogous to the glideslope for GPS approaches supporting WAAS vertical guidance (LNAV+V,
L/VNV, LPV) and is generated by the system to reduce pilot workload during approach. When an approach of
this type is loaded into the flight plan and GPS is the selected navigation source, the Glidepath Indicator (Figure
2-15) appears as a magenta diamond. If the approach type downgrades past the final approach fix (FAF), “NO
GP” is annunciated.
