Narrative:
On arrival descending through 6;000 feet received baro degraded message. All 3 altimeters set exactly the same and correct to ATIS report. Few seconds later; automatic flight FCU 1 fault. Captain PF (pilot flying) and lost auto pilot; auto thrust; flight directors both basically raw data. Selected fpv (flight path vector) and made sure captain was stabilized at about 5;000 feet. We were cleared to 4;000 feet. Advised ATC and immediately started working the problem with qrc; QRH. Challenging as we were in and out of tops trying to find good VMC box; bumpy. Worked problem; eventually fault reset and we landed uneventful.
