FOR TRAINING PURPOSES ONLY

The map format is similar to the arc format
but instead of a large CDI image it displays the
FMS map (Figure 16-19). This format is only
available when FMS is the active nav source.
This mode will be automatically deselected if
a non-FMS source is made active and it will re-
vert to the arc format. Additionally, when map
format is chosen on the left PFD it forces the
MFD into present position map mode (PPOS)
and other MFD map formats are not selec-
table. It is critical to remember that following
map lines is not an alternative to CDI displays.
For navigation, a lateral deviation display will
appear at the bottom of the attitude indicator
when map mode is chosen.
The same range limitations apply in this mode
as they did with the arc format.
Figure 16-19. PFD Map Format
Additional options for display with the FMS
map are available through the Control Display
Unit on the pedestal (see the CDU section
later in this PTM).
Below the FORMAT LSK is the TERR/RDR
LSK. This key allows for the display of either
terrain or radar images. These cannot be dis-
played simultaneously on the same display or
when the compass rose format has been se-
lected. The chosen option will be displayed in
cyan and large font. The display of these items
does NOT indicate that the unit is active (Ter-
rain and Radar must be turned ON from a dif-
ferent location). Below these labels is an area
reserved for detail about the selected option.
For instance, if RDR is selected, the display
will be cyan and the radar operating mode and
tilt would be displayed below RDR. If TERR
is selected, the display will be cyan and the ap-
propriate operating status for the terrain
would be displayed (e.g., “TERRAIN”, “TER-
RAIN FAIL”, “TERRAIN TEST”, etc.) (Figure
16-20).

Section
Both can also be deselected from the display
and would change the respective label to
white.
TFC line select key allows the TCAS display
to be turned ON or OFF on any of the three
formats. When the TCAS display is selected,
TFC will be cyan. When deselected, TFC will
be white. Below the TFC line is an area re-
served for TCAS messages (e.g., TCAS TEST,
TA ONLY, etc.) (Figure 16-20). The display of
cyan TFC does NOT indicate that TCAS is ac-
tually active. TCAS is activated with a different
selection discussed later in the TCAS section.
