Table 3B-37. Entry and Display of VNAV Parameters
Press Flight Plan Function Key - FPLN.
V indicates an altitude has been assigned at this waypoint.
Press right line select key to access Flight Plan Waypoint page for desired waypoint.
Enter flight level (or altitude) in the scratchpad.
Press altitude line select key to insert flight level (or altitude).
Enter vertical rate (or angle) in the scratchpad.
The VNAV information is displayed.
Press the insert rate (3R) or angle (3L).
Toggle between CLIMB and DESCNT selections.
Asterisk indicates rate is the fixed or entered quantity; after VNAV capture, the angle becomes fixed
and vertical speed becomes variable with groundspeed.
If the waypoint is an FMS approach MAP, the
altitude is displayed, but no entry is permitted. If an
angle is associated with the MAP altitude, the V
attribute will be displayed on the Flight Plan page. On
MDA approaches, no descent angle is defined for the
approach, so vertical guidance is disabled and the V
attribute is not displayed.
(3) Entry and Display of Climb or Descent
Path. If only an altitude/flight level is entered and no
climb or descent path is specified, the climb/descent
path is undefined and no vertical guidance is provided.
To activate vertical guidance to the assigned altitude,
either a climb/descent path rate or angle must be
defined, or a Direct-To VNAV will be executed.
If two consecutive waypoints are assigned
altitudes/flight levels, the default path is a straight-line
climb or descent between them, same as for a
published profile descent.
To specify a climb/descent path other than the
default, enter the desired angle (0.0 to 6.0 degrees) or
initial vertical rate (0 to 3500 fpm). Press the VNAV
line select key for angle or rate entry. Refer to Figure
3B-51 and Table 3B-38. Select either CLIMB or
DESCNT line select key on the Flight Plan Waypoint
