more deliberate cadence of
microphone keying.
NAV Receiver
The right portion of the display is
allocated to NAV receiver information.
The frequency channeling is similar to
the COMM when operating in the
frequency mode (Figure 1A and 1B).
The NAV increment/decrement knobs
are located on the right hand side of
the front panel. The outer knob
operates in 1 MHz steps and
increments/decrements the
STANDBY frequency display.
The inner knob operates in 50
kHz steps. The NAV receiver’s lower
and upper frequency limits are 108.00
MHz and 117.95 MHz. Exceeding the
upper limit of frequency band will
automatically return to the lower limit
and vice versa.
Depressing the NAV frequency
transfer button for 2 seconds or more
will cause the display to go in to the
ACTIVE ENTRY mode. Only the
ACTIVE frequency will be displayed
and it can be directly changed by
using the NAV inc/dec knobs. The
display will return to the
ACTIVE/STANDBY mode when the
NAV frequency transfer button is
pushed.
Depressing the mode button will
cause the NAV display to go from the
ACTIVE/STANDBY format to the
ACTIVE/CDI (Course Deviation
Indicator) format as shown in Figure
11.
FIGURE 11
Nav display active VOR frequency/
CDI format
The vertical “needle” moves side
to side similar to a mechanical CDI.
When the needle is centered, the
aircraft is on the selected OBS
course. When the active frequency is
tuned to a VOR frequency, the center
of the CDI scale displays the “TO” or
“FROM” indicator.
In the CDI mode, the increment/
decrement knob (pushed in) channels
the ACTIVE frequency window and
depressing the frequency transfer
button will cause the ACTIVE
frequency to be placed in blind
storage and the STANDBY frequency
(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”
indication by depressing the mode
button for 2 seconds. This OBS
display is independent 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 frequency area is replaced by
“LOC” (Figure 12).
