KFS 578A CONTROLS AND DISPLAYS
The KFS 578A Control Unit is the master control for both the TCAS sys-
tem and transponder. The KFS 578A will also display the selected 4096
ATC code and current mode of operation in the display window. Versions
are available to control one or two transponders. 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.
