VERTICAL SPEED INDICATOR (VSI)
The Vertical Speed Indicator (VSI) displays the aircraft vertical speed on a fixed scale with labels at 2000 and
4000 fpm and minor tick marks every 1000 fpm (Figure 2-13). Digits appear in the pointer when the climb or
descent rate is greater than 100 fpm. If the rate of ascent/descent exceeds 4000 fpm, the pointer appears at the
edge of the tape and the rate appears inside the pointer.
A magenta chevron is displayed as the Required Vertical Speed Indication (RVSI) for reaching a VNV Target
Altitude once the “TOD [Top of Descent] within 1 minute” alert has been generated. 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 PFD.
VERTICAL DEVIATION
The Vertical Deviation Indicator (VDI) uses a magenta chevron to indicate the baro-VNV vertical deviation
when Vertical Navigation (VNV) is being used. The VDI (Figure 2-13) 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 PFD.
The Glideslope Indicator (Figure 2-14) 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, LNAV/VNAV, 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 2-15) appears as a magenta diamond when the aircraft reaches a point prior to the FAF. If the
approach type downgrades past the final approach fix (FAF), “NO GP” is annunciated.
