AeroNav 900/880 Series Pilot's Guide
TRANSPONDER CONTROL AND DISPLAY
If the AeroNav has been configured to communicate with a
remote transponder, then the AeroNav will provide display and
control of both transponder mode and code.
Transponder Display
The transponder mode and code is displayed in a datablock that
can be configured to be displayed along the right and top sides of
the display.
A round "R" reply indication will light up in the transponder
datablock area whenever the transponder is in an active Reply
state.
If the AeroNav is unable to communicate with the remote
transponder, an associated CAS message is displayed and the
transponder data blocks may be replaced with a red-X.
Typical Transponder Datablock Locations
Transponder Control
The preferred method of controlling the transponder is using a
keyboard. Touch a transponder data block to show the keyboard.
If the data block contains an "Ident" soft LSK, touch anywhere in
the data block except the soft LSK.
