Hey all,
Has anyone experienced the following?
When powering up, we are seeing a PFD and MFD indication "TCAS FAIL".
When we conduct the TCAS test (through the XPDR page of the MCDU) we get the following indications: PASS in the upper left of the XPDR page, during the test ADS-B indicates OFF, the PFD/MFD TCAS FAIL indications remain, we DON'T get the TCAS symbology on the MAP page (as we should), and we DON'T get the aural warning "TCAS system test, OK).
The aircraft is a long nose with Phase 7 software. We have TCAS II. We've checked antenna connections but there isn't really much else in the maintenance documents (from our engineer) regarding troubleshooting. Any suggestions?
Thanks
