VERTICAL NAVIGATION (VNV) INDICATIONS
When a VNV flight plan has been activated, VNV indications (VNV Target Altitude, RVSI, VDI) appear on the
PFD in conjunction with the “TOD within 1 minute” message and “Vertical track” voice alert. See the Flight
Management and AFCS sections for details on VNV features. VNV indications are removed from the PFD
according to the criteria listed in the table.
