edge of the PFD and expands as necessary to
display any active CAS messages (up to 14 in
a window) (Figure 16-24). If more than 14
messages appear, they can be scrolled.
NAV/COM FREQUENCIES AND
NAVIGATION DATA WINDOWS
Across the top of the PFD are avionics settings
and data indications, including VHF NAV and
COM frequencies (active and standby), and
navigation status data.
PFD CONTROLS
Each PFD is controlled by knobs and pushbutton
keys on its bezel, and/or by pilot operation
of the AFCS or MFD/FMS controller.
The following general discussion of controls
is also applicable to the other controllers.
Controls
Garmin displays (PFD and MFD) and control
panels (audio panel, AFCS controller, and
FMS controller) have various types of knobs,
buttons and switches. Refer to Figure 16-25
for PFD controls locations and Table 16-5 for
a description on those controls.
Softkeys
Along the bottom of the PFD, the bezel contains
12 “softkeys” marked with upward-pointing
triangles. These keys do not have a single,
specific, permanent function. They have different
purposes at different times, as determined
by the G1000 software.
Some (or all) softkeys have labels appearing
immediately above them on the display. The
labels change depending upon pilot settings
and/or current conditions. Navigating the
lower level menus is done through the top
level softkey menu.
When the label for a specific feature is toggled
off, the text is white on a black background.
When the label is toggled on, the text is black
on a light gray background.
When the BACK softkey is available (on the
right end of the softkeys), this key can be pressed
to escape the current menu and return to the
previous menu display. For details on the menus
for PFD softkeys. refer to Figure 16-26.
TRANSPONDER DISPLAY AND
CONTROL
The PFD depicts current transponder status in
the black XPDR box on the bottom right side
