VNV TARGET ALTITUDE CAPTURE MODE (ALTV)
NOTE: Armed VNV Target Altitude and Selected Altitude capture modes are mutually exclusive. However,
Selected Altitude Capture Mode is armed implicitly (not annunciated) whenever VNV Target Altitude Capture
Mode is armed.
VNV Target Altitude Capture is analogous to Selected Altitude Capture Mode and is armed automatically

is annunciated in the Navigation Status Box, the active VNV Target Altitude is displayed above the Vertical
SpeedIndicator(seeFigure7-12).
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 green

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

Changing the VNV Target Altitude
NOTE: 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).
