Narrative:
After sequencing the box for arrival the fmgcs dumped all navigation and performance data. ECAM to manually set field elevation for pressurization came shortly after. Had to use standby navigation for ILS and go to the flight handbook for landing speeds. Landing and taxi in was uneventful. On arrival was notified by maintenance that they received a fault message for FMGC 1. I have no idea why the computers were working but dumped all data.
