6. NAV/FREQUENCY TRANSFER BUDON (E.. ) --
Interchanges the NAV Active and STANDBY frequencies.
Depressing the NAV frequency transfer button for 2 seconds
or more will cause the display to go into 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.
7. MODE SELECTOR BUDON -- Depressing the mode button
will cause the NAV display to go from the ACTIVE/STANDBY
format to the ACTIVE/CD I (Course Deviation Indicator) format.
In the CDI mode, the frequency inc/dec knob (pushed in)
channels the ACTIVE frequency. 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. This OBS
display is independent of any OBS course selected on an
external CDI. 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 "LaC". When the
received signal is too weak to ensure accuracy the display will
"FLAG".
Depressing the mode button again will cause the NAV display
to go from the ACTIVE/CDI format to the ACTIVE/BEARING
format. In the BEARING mode, the frequency inc/dec knob
channels the ACTIVE freq uency window . 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.
In bearing mode, the right hand window of the NAV display
shows the bearing TO the station. When a too weak or invalid
VOR signal is received the display flags (dashes) .
