CHAPTER 8 TRAFFIC DISPLAY INTERFACE
The SN3500 can display nearby transponder equipped aircraft
when interfaced with a compatible TAS or TCAS processor. Please
refer to the Pilot’s Guide for the specific traffic system installed in
the aircraft for a complete description of the capabilities.
Note: The SN3500 can be interfaced to a TCAS II processor but will
function only as a traffic display as vertical guidance information
required for conflict resolution will not be displayed.
