NO.
DESCRIPTION/FUNCTION
1
Press Flight Plan Function Key - FPLN.
2
V indicates an altitude has been assigned at this waypoint.
3
Press right line select key to access Flight Plan Waypoint page for desired waypoint.
4
Enter flight level (or altitude) in the scratchpad.
5
Press altitude line select key to insert flight level (or altitude).
6
Enter vertical rate (or angle) in the scratchpad.
7
The VNAV information is displayed.
8
Press the insert rate (3R) or angle (3L).
9
Toggle between CLIMB and DESCNT selections.
10
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, the 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°) or initial
vertical rate (0 to 3500 fpm). Press the VNAV line
select key for angle or rate entry. Refer to Figure
3C-57 and Table 3C-44. Select either CLIMB or
DESCNT line select key on the Flight Plan Waypoint
page.
