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 2-15) 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 and AFSC sections 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 2-16) appears to the left of the Altimeter whenever an ILS frequency is
tuned in the active NAV field. 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 displayed in
place of the diamond.
The glidepath is analogous to the glideslope for GPS approaches supporting WAAS vertical guidance (LNAV+V,
L/VNV, LPV). When an approach of this type is loaded into the flight plan and GPS is the selected navigation
source, the Glidepath Indicator (Figure 2-17) appears as a magenta diamond during the approach. If the
approach type downgrades past the final approach fix (FAF), “NO GP” is displayed in place of the diamond.
