FLIGHT INSTRUMENTS
VERTICAL NAVIGATION (VNV) INDICATIONS
When a VNV flight plan has been activated, VNV indications (VNV Target Altitude, RSVI, VDI) appear on the
PFD in conjunction with the “TOD within 1 minute” message (Figure 2-35) and “Vertical track” voice alert. See
the GPS Navigation section for details on VNV features. VNV indications are removed from the PFD according
to the criteria listed in Table 2-2.
