FLIGHT INSTRUMENTS
VERTICAL DEVIATION, GLIDESLOPE, AND GLIDEPATH INDICATORS
The Vertical Deviation Indicator (VDI; Figure 2-12) 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. The VDI is removed from the display if vertical deviation becomes invalid. See the GPS
Navigation 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 2-13) 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 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
2-14) appears as a magenta diamond. If the approach type downgrades past the final approach fix (FAF), “NO
GP” is annunciated.
Full-scale deflection (two dots) is 1000 feet.
