An integrity monitor for TCAS mutual suppression checks the interface circuits and cabling of the suppression system that lies between the TCAS processor and the transponder. The monitor starts by interrogating the transponder while disabling suppression. If no reply is received, the transponder is not functional. If a reply is received, interrogation of the transponder occurs again, however, this time suppression is enabled. If a reply is received, the suppression system has failed and TCAS alarms will be inhibited. If a reply is not received, the suppression system is working.
