waypoint, if it has an altitude/flight level
assigned (indicated by the V attribute). If
the waypoint on line 3 does not have an
altitude/flight level assigned the V NAV
label is blanked.
Indicates V attribute.
VNAV CLIMB/DESCNT path synchronizes
to the Direct-To path.
If an angle is entered, the vertical rate will be
dynamically updated based on the angle prior to and
during capture and the subsequent vertical path. An *
will appear next to the angle value to indicate that it is
fixed. If a vertical rate is initially entered, the angle is
updated based on the entered rate prior to the capture
points plus an asterisk appears next to the rate. At
capture of the vertical path, the angle becomes fixed
and the entered rate is now updated during the
climb/descent. The asterisk is now displayed next to
the angle to indicate the fixed value.
(4) Direct Climb or Descent Path Display.
The DIRECT CLIMB/ DESCNT vertical rate or angle on
the Flight Plan Waypoint page is computed based on
the FMS-800 present position and altitude for any
waypoint with an altitude assigned, not just for the
active waypoint. Refer to Figure 3B -52 and Table
3B-39. This advisory enables the pilot to plan his
climb or descent. He is apprised of the actual vertical
maneuver required. For example, ATC delays his
climb/descent clearance beyond the planned Bottom
Of Climb (BOC) or Top Of Descent (TOD), or clears
the aircraft Direct-To another waypoint using the
specified waypoint altitude. This is also the value that
will be inserted if the pilot were to select a VNAV
