NAV Button
The NAV button controls selection of the nav-
igation mode. Heading mode remains active
until course intercept. After intercept, the
FGC maintains the selected course. The active
NAV identifier annunciates on the PFD
(FMS, VOR1, LOC2, etc.). The NAV mode
should be used during the enroute phase of
flight, for appropriate terminal procedures
and when flying an approach to an MDA. This
excludes an FMS NAV-to-NAV capture as ref-
erenced in the APPR section. Refer to the
VNAV section of this chapter for more infor-
mation on how this mode interacts with FMS
vertical navigation.
CRS Knobs
The CRS knobs select the course to be flown
on the respective PFD. This knob is not active
when FMS is the active navigational source.
PUSH DIRECT Button
The PUSH DIRECT button within the CRS
knob automatically selects a direct course to
the active VOR, and centers the CDI on the
respective PFD. This button is not active when
either FMS or LOC is the active navigational
source.
Pitch Mode
Pitch mode is a basic vertical operating mode.
It activates when no other vertical mode is ac-
tive and the flight director is on. The annunci-
ation PTCH displays on the PFD. When active,
the FGC maintains the pitch attitude which
existed when the pitch mode was engaged.
This will occur when the previously selected
vertical mode is pressed again (deselected) or
when the UP/DOWN Pitch Wheel is moved
and VS mode is not active.
Rotating the UP/DOWN pitch wheel changes
the pitch reference value. When the autopilot
is not engaged, pushing the SYNC button on
the control wheel synchronizes the pitch ref-
erence to the current attitude.
VS Button
The VS button controls selection of the verti-
cal speed mode. When VS is activated, the
FGC initially maintains the current aircraft
vertical speed when the mode is selected. Ro-
tating the UP/DOWN pitch wheel changes the
vertical speed reference value. When the au-
topilot is not engaged, pressing the SYNC but-
ton on the control wheel synchronizes the VS
reference to the current vertical speed.
VS and the vertical speed reference value ap-
pear on the PFD (Figure 16-71). An up arrow
appears for climbs and a down arrow appears
for descents. A reference arrow (bug) appears
on the vertical speed scale adjacent to the se-
lected vertical speed.

VNAV Mode
The VNAV button controls Vertical Navigation
mode selection and is annunciated on the PFD
as a “V” located in front of the active vertical
mode (e.g., VPTCH, VVS, VALTS, etc.). The
flight management computer (FMC) deter-
mines the VNAV capture point and provides
vertical steering commands to waypoints that
contain altitude restraints in the FMS. See the
VNAV section and the Flight Guidance Mode
Annunciations table for more information.
