Vertical Speed Display
The current vertical speed is shown by a green pointer on a vertical white scale; the
green pointer drags a green vertical line from the center of the scale. Vertical speed
(when 200 feet/minute or greater) is numerically repeated at the bottom of the scale
followed by an arrow pointing “up” for climb, or “down” for descent.
The vertical speed is selected by using the VS/Pitch Wheel on the FCP and the
magenta numerical value is displayed at the top of the Vertical Speed scale with a
corresponding up or down arrow as selected.
The FMS Vertical Navigation computer continuously calculates vertical speed
required to reach the next point on the flight plan at the altitude required. The required
vertical speed when greater than 500 fpm for FMS VNAV is displayed on the vertical
speed scale in the form of a cyan circle.
For Precision-Plus-equipped aircraft, the cyan circle will be
displayed if VNAV is selected or VNAV advisory enabled.
TCAS advisories display on the VS scale as green or red lines. A
green line shows a recommended “fly-to” range of vertical
speeds. A red line shows “avoidance” or “exit” vertical speeds.
TCAS modes and messages are also displayed below the VS
scale as appropriate (see Chapter 17 Navigation Systems for
further details).

Navigation Displays
Vertical Deviation Display (GS, FMS and VNAV)
The ILS glideslope vertical deviation display appears when all conditions are met. Use
the on-side DCP to select FMS or LOC as the active NAV source. If deviation data
becomes invalid, this display is replaced with a red GS (flag) annunciation. When
conducting a back course approach, the scale displays without a pointer or flag
annunciation.
With LOC selected as the active NAV source, glideslope deviation is shown by the
position of a diamond-shaped pointer relative to the deviation scale. The scale consists
of two dots above and two dots below center. When the pointer moves to the top or
bottom of the scale, it changes to a half diamond (triangle) pointing in the direction of
the glideslope. A star against the same scale displays FMS glideslope vertical
deviation.
Marker Beacon Annunciation
Marker beacon status is annunciated by a cyan boxed “OM” (Outer Marker), yellow
boxed “MM” (Middle Marker), or by an empty white box (Inner Marker).

Horizontal Situation Indicator (HSI) Function
The PFD has a Horizontal Situation Indicator located at the bottom center. It consists
of an airplane symbol and a compass rose. The compass rose is graduated in fivedegree
marks, with numeric labels at every 10 degrees and letters at N, E, S and W.
