NAV RADIO SELECTION AND ACTIVATION
The NAV Frequency Box is composed of four fields; two standby fields and two active fields. The active
frequencies are on the right side and the standby frequencies are on the left.
A NAV radio is selected for navigation by selecting the
CDI
Softkey located on the PFD. The active NAV
frequency selected for navigation is displayed in green. Selecting the
CDI
Softkey once selects NAV1 as the
navigation radio. Selecting the
CDI
Softkey a second time selects NAV2 as the navigation radio. Selecting the
CDI
Softkey a third time activates GPS mode. Selecting the
CDI
Softkey again cycles back to NAV1.
While cycling through the
CDI
Softkey selections, the selected NAV standby frequency is selected for tuning,
the Frequency Transfer Arrow is placed in the selected NAV Frequency Field, and the active NAV frequency
color changes to green.
The three navigation modes that can be cycled through are:
-
VOR1 (or LOC1) – If NAV1 is selected, a green single line arrow (not shown) labeled either VOR1 or LOC1
is displayed on the HSI and the active NAV1 frequency is displayed in green.
-
VOR2 (or LOC2) – If NAV2 is selected, a green double line arrow (shown) labeled either VOR2 or LOC2 is
displayed on the HSI and the active NAV2 frequency is displayed in green.
-
GPS – If GPS Mode is selected, a magenta single line arrow (not shown) appears on the HSI and neither NAV
radio is selected. Both active NAV frequencies are then displayed in white and the previously selected NAV
standby frequency remains selected for tuning.
See the Flight Instruments Section for selecting the DME and Bearing Information windows and using VOR
or ADF as the source for the bearing pointer.
The NAV Frequency Box displays the decoded Morse Code station identifier that is received from the navigation
source. Audio verification of the selected station can be accomplished by selecting the corresponding NAV
radio on the audio panel and pushing the
NAV VOL/ID
Knob.
NAV radios are selected for listening by pressing the corresponding keys on the Audio Panel. Pressing the
NAV1
,
NAV2
,
ADF
,
or
DME

selects and deselects the navigation radio source. Selected audio can be heard over
the headset and the speakers (if selected). All radios can be selected individually or simultaneously.
