VERTICAL SPEED INDICATOR (VSI)
The Vertical Speed Indicator (VSI; Figure 2-20) displays the aircraft vertical speed with numeric labels and
tick marks at 2000 and 4000 fpm in each direction on the non-moving tape. Minor tick marks are at intervals
of 1000 fpm. The current vertical speed is displayed in the pointer, which also points to that speed on the
non-moving tape. 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 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; see Figure 2-20) 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 2.4, Supplemental
Flight Data, for more information about VNV indications on the PFD.
