Vertical Deviation Indicator (VDI)
The Vertical Deviation (Glideslope) Indicator (VDI) appears to the left of
the VSI whenever an ILS frequency is tuned in the active NAV field. A green
diamond acts as the VDI Indicator, like a glideslope needle on a conventional
indicator. If a localizer frequency is tuned and there is no glideslope signal, “NO
GS” is annunciated. The glideslope on an ILS approach is only shown if the
current heading is within 90
°
of the selected inbound course. This prevents the
glideslope from being displayed during localizer backcourse approaches.

The vertical deviation is similar to the glideslope for GPS approaches
supporting WAAS vertical guidance (LNAV+V, L/VNAV, LPV, LP+V). When
an approach of this type is loaded into the flight plan and GPS is the selected
navigation source, the Vertical Deviation Indicator appears as a magenta
diamond. If the approach type downgrades to LNAV past the final approach fix
(FAF), or the approach only supports LNAV service, “NO GP” is annunciated.
