active enroute VNAV altitude target. Note that if the constraint is
a window constraint, the lower altitude is used as the target.
DEFINING THE DESCENT PATH
Enroute VNAV always uses an angle to define the descent path.
Using the Setup page, the desired angle can either be set directly
or set by specifying a target vertical speed and having the FMS
compute the angle.
Setup Page Descent Angle Selection
Using the enroute VNAV altitude target and the associated
waypoint, the IFD will project that angle along the flight path all
the way to the current aircraft altitude. That point is depicted on
the map as a green circle labeled “TOD” (top-of-descent). When
enroute VNAV is allowed and the aircraft reaches the TOD point,
the IFD will automatically commence enroute VNAV.
