KFS 578A Single or Dual Mode S Control Unit (Dual Unit shown).
KFS 578A CONTROLS AND DISPLAYS
The KFS 578A Control Unit is the master control for the transponder.
The KFS 578A will also display the selected 4096 ATC code and cur-
rent mode of operation in the display window. Versions are available to
control one or two transponder. A “Fail” annunciation indicates failure of
the selected transponder, antenna or control data.
Note: If the KFS 578A is interfaced to a MST 67A Mode S transponder
and the MST 67A senses a failure, a failure annunciation will be shown.
A maintenance check should be performed.
