KFS 578A TRANSPONDER/ TCAS CONTROL UNIT

KFS 578A Single or Dual Mode S/TCAS Control Unit (Dual Unit shown).

KFS 578A CONTROLS AND DISPLAYS

The KFS 578A Control Unit is the master control for both the TCAS
system 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.
