Flight Management and AFCS sections for details on VNV features, and refer to Section 2.2, Supplemental
Flight Data, for more information about VNV indications on the PFD.
VERTICAL DEVIATION
The Vertical Deviation Indicator (VDI; Figure 2-10) 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 AFCS sections for details on VNV features, and refer
to Section 2.2, Supplemental Flight Data, for more information about VNV indications on the PFDs.
The Glideslope Indicator (Figure 2-11) appears to the left of the Altimeter whenever an ILS frequency is tuned
in the active NAV field and the aircraft heading and selected course are within 107°. 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.
NOTE:
The Glidepath Indicator appears on the display as soon as the Final Approach Fix (FAF) becomes the
active waypoint. Depending on procedure design, pilot action, and/or ATC clearance, the aircraft may be
centered on or above the glidepath when the Glidepath Indicator appears.
The Glidepath Indicator is a vertical deviation scale for RNAV GPS approaches supporting SBAS vertical
guidance (LNAV+V, L/VNAV, LPV, and LP+V service levels). The Glidepath Indicator, a magenta diamond
(Figure 2-12) appears on the display as soon as the Final Approach Fix (FAF) becomes the active waypoint, and
FMS is the selected navigation source. Full-scale deflection (two dots), is angular with upper and lower limits.
The upper limit is +/-150 meters and lower limits depend on approach service level.
• LNAV/VNAV is +/- 45 meters.
• LPV/LP+V is +/- 15 meters.
If the approach service level downgrades past the final approach fix (FAF), “NO GP” is displayed in place of
the diamond.
