cause the ACTIVE frequency to be placed
in blind storage and the STANDBY fre-
quency (in blind storage) to be displayed
in the ACTIVE window display.
When the ACTIVE window is tuned to
a VOR frequency, the standby frequency
area is replaced by a three digit OBS
(Omni Bearing Selector) display. The
desired OBS course can be selected by
pulling out the inner NAV frequency knob
and turning it. The CDI needle may be
automatically centered with a "TO" indica-
tion by depressing the mode button for 2
seconds. This OBS display is indepen-
dent of any OBS course selected on an
external CDI or HSI. An "OBS" in the
middle of the NAV display will flash while
the inner NAV frequency knob is pulled
out. The CDI is displayed on the line
below the frequency/OBS.
When the ACTIVE window is tuned to a
localizer frequency, the standby frequen-
cy area is replaced by "LOC" (Figure 12).
When the received signal is too weak
to ensure accuracy the display will "flag".
See Figure 13.
Depressing the mode button will
cause the NAV display to go from the
ACTIVE/CDI format to the
ACTIVE/BEARING format. In the BEAR-
ING mode, the increment/decrement
knob channels the ACTIVE frequency
window and depressing the frequency
transfer button will cause the ACTIVE fre-
quency to be placed in blind storage and
the STANDBY frequency (in blind stor-
age) to be displayed in the ACTIVE win-
dow display. In bearing mode of opera-
tion, the right hand window of NAV dis-
play shows the bearing TO the station.
Figure 14 illustrates the NAV side of
the display in this mode.
When a too weak or invalid VOR sig-
nal is received the display flags as shown
in Figure 15.
Another push of the mode button will
cause the NAV display to go from the
ACTIVE/BEARING format to the
ACTIVE/RADIAL format as shown in
Figure 16. In the RADIAL mode, the
