NOTE
The map range increases or decreases one increment
each time the RNG + or - Button is pressed. Press and
hold to continuously increase or decrease the range.
NOTE
The Basemap declutter setting can determine what is
displayed for a particular range. Refer to Chapter5,
Table5-9 for more information.

4.6. Vertical Speed Indicator
When the 360° Compass Mode is selected, the Vertical Speed Indicator (VSI) is rendered
on the right side of the Navigation Display, showing a numerical and graphical
representations of vertical speed. The VSI shows the change in pressure altitude over
time. The graphical display is a white VSI Tape, with the numerical value at the top
(Figure 4-106). In either ARC Compass mode, only the numerical value isshown.
The VSI Tape displays rates of ±2,000 FPM while the numerical value displays rates up to
±9,990 FPM. When the vertical speed exceeds ±2,000 FPM, a triangle caps the VSI Tape
(Figure 4-107).
The VSI Tape is nonlinear, giving more display area to the 0 to ±1,000 FPM range than
to the ±1,000 to ±2,000 FPM range. Tick marks are presented only in the direction of
the climb or descent to provide visual cues for trends. The VSI’s numerical value, tape,
and scale are only shown if the aircraft is climbing or descending more than ±100 FPM.
During level ight in calm air conditions, the Tape, scale, and zero reference line are
removed from the display. The numerical value is always enabled and shows dashes
when vertical rates are out of range.
