Vertical Deviation/Glideslope Indicator
The Vertical Deviation/Glideslope Indicator is a
window on the left side of the Altimeter. The window
appears when an ILS is tuned in the active NAV field (and
selected on the audio panel). A green diamond appears
and acts as the vertical deviation indication, just like a
glideslope needle on a conventional indicator.
Marker Beacon Annunciations
Marker Beacon Annunciations are displayed on the PFD
to the left of the Altitude Reference Box. Outer marker
reception is indicated by a blue light, middle by amber,
and inner by white (refer to the Audio Panel section for
more information).
