Vertical Speed Indicator (Vsi); Vertical Deviation - Garmin G950 Pilot's Manual

FLIGHT INSTRUMENTS

VERTICAL SPEED INDICATOR (VSI)

The Vertical Speed Indicator (VSI, Figure 2-14) displays the aircraft vertical speed using a non-moving tape
labeled at 1000 and 2000 fpm with minor tick marks every 500 fpm. The current vertical speed is displayed
in the pointer along the tape. Digits appear in the pointer when the climb or descent rate is greater than 100
fpm. If the rate of ascent/descent exceeds 2000 fpm, the pointer appears at the corresponding edge of the tape
and the rate appears inside the pointer.
A magenta chevron bug is displayed as the Required Vertical Speed Indication (RVSI; Figure 2-14) for reaching
a VNV Target Altitude once the "TOD [Top of Descent] within 1 minute" alert has been generated. Refer to
Section 2.2, Supplemental Flight Data, for more information about VNV indications on the PFD.

VERTICAL DEVIATION

The Glidepath Indicator is only shown for aircraft with GIA 63W Integrated Avionics Units when
NOTE:
WAAS is available.
The Vertical Deviation Indicator (VDI; Figure 2-13) is a magenta chevron indicating the baro-VNV vertical
deviation when Vertical Navigation (VNV) is being used. The VDI appears in conjunction with the "TOD within
1 minute" alert. The VDI is removed from the display if vertical deviation becomes invalid. See the Flight
Management Section 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 displayed in
place of the diamond.
The glidepath is analogous to the glideslope for GPS approaches supporting WAAS vertical guidance (LNAV+V,
L/VNAV, LPV). 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 during the approach. If the
approach type downgrades past the final approach fix (FAF), "NO GP" is displayed in place of the diamond.
Full-scale deflection (two dots) is 1000 feet.
