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) is a magenta chevron indicating the baro-VNV vertical deviation when
Vertical Navigation (VNV) is being used. The VDI appears in conjunction with the “TOD within 1 minute”
alert. 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 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 heard.
The glidepath is analogous to the glideslope for GPS approaches supporting WAAS vertical guidance (LNAV+V,
L/VNAV, LPV). When an approach of this type is loaded into the flight plan and GPS is the selected navigation
source, the Glidepath Indicator appears as a magenta diamond during the approach. If the approach type
downgrades past the final approach fix (FAF), “NO GP” is heard.
Full-scale deflection of two dots is 1000 feet.
