Nav Receiver; Nav Display Active Vor Frequency/Cdi Format - Honeywell Bendix King Silver Crown Plus KX 155A Manual

ment for the ground station decoder is
such that it will not respond to very rapid
or "staccato" transmissions. If the first
attempt at lighting the runway lights is
unsuccessful, repeat with a slower, more
deliberate cadence of microphone key-
ing.

NAV Receiver

The right portion of the display is allo-
cated to NAV receiver information. The
frequency channeling is similar to the
COMM when operating in the frequency
mode (Figure 1A and 1B). The NAV incre-
ment/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 fre-
quency 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 trans-
fer button for 2 seconds or more will
cause the display to go in to the ACTIVE
ENTRY mode. Only the ACTIVE frequen-
cy 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. The verti-
cal "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/decre-
ment knob (pushed in) channels the
ACTIVE frequency window and depress-
ing the frequency transfer button will
