FOR SIMULATION PURPOSES ONLY
Frequency selection is similar to that of the KN53 above. Station identification
is achieved using the NAV 2 on the ACS.
Depressing the MODE button will cycle the unit through its various display
modes in the following order:
•
Active/Standby Frequency.
•
Active/ Course Deviation Indicator (CDI).
•
Active/Bearing (To).
•
Active/Radial (From).
Active/Standby Frequency Mode
Active and Standby frequency windows display selected frequencies. No
course information is displayed.
Active/CDI Mode
In this mode, with the NAV frequency control pushed in, rotation of the
frequency controls changes the frequency in the Active display. Depressing
the NAV frequency transfer button will place the Active frequency in blind
storage and transfer the Standby frequency to the Active window.
When the Active window is tuned to a VOR frequency the Standby
frequency area is replaced by a 3 digit OBS display.
The OBS course value is tied to the NAV2 Indicator on the Left side of the
instrument panel.
If no NAV signal is found for the desired frequency, the text ‘FLAG’ will appear
on the radio.
Active/Bearing Mode
The frequency in the Active window is changed as above and the NAV
frequency transfer button operates in the same fashion.
Pulling the inner frequency control has no effect. The Standby frequency
area displays a bearing TO the selected VOR facility.
Should the received signal be too weak to ensure accuracy then the display
will show “- - -”.
