Synopsis
A300 flight crew reported on departure experiencing multiple system malfunctions resulting in their return to the departure airport.
Narrative
Shortly after takeoff from Runway XXL at ZZZ; the crew noticed several abnormalities that occurred with the aircraft. There was audible clicking sounds of the #1 pitch trim lever disengaged; both auto throttles disengaged; both Autopilots disengaged; Captain side flight director disappeared; and all three system's 'pitot' annunciators on the overhead panel illuminated. The faults displayed on the ECAM were: FLT CTL PITCH TRIM 1 faultATS 2 FaultCAPT TAT HEAT FAULT- ADC1 monitorCABIN PRESS REG 1 faultI was the pilot monitoring and told First Officer (FO) to continue flying the aircraft and to handle communications. I monitored aircraft state and flight path. Once these were stabilized; the ECAM items were addressed. The pilot flying (PF) FO side ADC and flight director were operating normally. I switched my ADC and Flight Director reversion switches to the FO side and restored these systems. ATC had cleared us to FL230 and we accepted this clearance knowing that we may have to request a level off. Somewhere in the vicinity of FL 200; the FO's altimeter became erratic and varied roughly 200-300 ft. The FO also lost his Autopilot. Neither Autopilot could be restored. These failures made it clear that we needed to level off and request to return to ZZZ. After handling ECAM and reviewing QRH; i took back communications and requested from ATC that we return back to ZZZ. ATC was very accommodating and we flew the ILS XXR and landed uneventfully. After landing; the crew coordinated with Maintenance and gave as much detail as possible concerning the discrepancies that took place.Cause: Aircraft systems malfunction.
Second reporter narrative
After takeoff climbing through the flight levels the Captains ADC started to fail so we lost autothrottles; his flight director; pitch trim...we swapped his ADC and he took my flight director on his reversion panel. Shortly thereafter my First Officer (FO) side started having erratic altitude indications which shortly turned to Autopilot kicking off and loss of flight director. We quickly decided it wasn't smart to be in the flight levels; with no accurate ADC; reliable flight directors or Autopilot as we would be non RVSM compliant. We decided the safest course of action was to return to ZZZ. we landed with no further problems.Cause: Maintenance issue.
