VNV Target Altitude Capture is analogous to Selected Altitude Capture Mode and is armed automatically

after the VNV Key is pressed and the next VNV Target Altitude is to be intercepted before the Selected  Altitude.  
The annunciation ‘ALTV’ indicates that the VNV Target Altitude is to be captured. VNV Target Altitudes are
shown in the active flight plan or direct-to (with vertical constraint), and can be entered manually or loaded 
from a database (see the Flight Management Section for details). At the same time as “TOD within 1 minute”
is annunciated in the Navigation Status Box, the active VNV Target Altitude is displayed above the Vertical
Speed Indicator (see Figure 7-14).

As the aircraft nears the VNV Target Altitude, the flight director automatically transitions to VNV Target 

Altitude Capture Mode with Altitude Hold Mode armed. This automatic transition is indicated by the magenta
‘ALTV’ annunciation flashing for up to 5 seconds and the appearance of the white ‘ALT’ annunciation. The
active VNV Target Altitude is shown in magenta above the Vertical Speed Indicator.

At  50  feet  from  the  VNV  Target  Altitude,  the  flight  director  automatically  transitions  from  VNV  Target

Altitude Capture to Altitude Hold Mode and tracks the level leg. As Altitude Hold Mode becomes active, the
white ‘ALT’ annunciation moves to the active vertical mode field and flashes magenta for 5 seconds to indicate
the automatic transition. The flight director automatically arms Vertical Path Tracking, allowing upcoming
descent legs to be captured and subsequently tracked.

Pressing the CWS Button while in VNV Target Altitude Capture Mode does not cancel the mode.

Changing the current VNV Target Altitude while VNV Target Altitude Capture Mode is active causes the

flight director to revert to Pitch Hold Mode. Vertical Path Tracking and the appropriate altitude capture
mode are armed in preparation to capture the new VNV Target Altitude or the Selected Altitude, depending 
on which altitude is to be intercepted first.

VNV  target  altitudes  can  be  changed  while  editing  the  active  flight  plan  (see  the  Flight  Management

Section for details).

Current Speed Control (if available) can be engaged if the the autopilot is engaged and Altitude Hold Mode

(ALT) or VNV Target Altitude Capture (ALTV) Mode is active. When the CSC Key is pressed, the Full Authority 
Digital Engine Control (FADEC) varies engine thrust to maintain the desired Airspeed Reference (green Airspeed 
Reference Bug), within a certain control range.

For CSC engagement and disengagement detailed conditions, see the approved Pilot’s Operating 

Handbook (POH).
