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 Section for details on VNV features. VNV indications are removed from the PFD according to the
criteria listed in Table 2-2.
