VNV PROFILE
The VNV profile can be changed by one of the following means:
• Changing the Flight Path Angle (FPA) for the descent segment
• Changing the target vertical speed for the descent segment
Changes to the VNV profile apply to the current active waypoint only. The VNV profile is not modifiable
if there is no active waypoint. An invalid entry results in the previous value being restored. The VNV
profile modification is invalid if it results in any of the following conditions:
• The maximum allowed FPA is exceeded
• The calculated target vertical speed exceeds the maximum allowed
• The TOD point is now located behind the aircraft’s present position or an s-turn would be required to
capture the modified vertical profile
• Modifying the vertical speed target for the current waypoint
The VS TGT will be computed using the FPA and current ground speed and updated on the display
periodically. If there is an active waypoint with a vertical component, a valid ground speed, and the
system determines the aircraft is airborne, the pilot can select and modify the VS TGT. Updates to the
field will cease when the field is selected for modification.
