Narrative:

Flying on autoplt with autothrottle, intercepted localizer on runway 27L, then called for gear down. As gear came down, multiple non pertinent aural and visual warnings began going off. 'Retard' plus gear and confign warnings were the memorable ones, we were at 4000 ft. Aircraft appeared to be thinking it was in flare mode just above runway. Speed decayed rapidly and we were simply confused by all the different warnings going off, so I disconnected autothrottles and autoplt and hand flew plane off the approach to an area south of field to investigate what worked and what didn't. Trial gear re-extension was not a problem except for radio altimeter warnings at 4000 ft, I should not have had them until about 3100 ft. Made passenger announcement about event. I decided to return and fly another approach (still in IMC with high surface winds) to runway 27L. Different flap confign and approach mode (vertical speed versus GS), but still got same events at gear extension. This time I continued the approach and tried to ignore the warnings. The plane was performing in spite of aural warnings. Very rough approach due to high winds. Good 'clear' exercise since we were getting multiple confusing warnings but with no ECAM checklists to follow. Callback conversation with reporter revealed the following information: the reporter stated the direct cause of the multiple warnings is unknown. The reporter said the approach was made in heavy rain and high winds. The reporter stated there was no ECAM checklist for this situation. The reporter stated the autothrottle and autoplt was disconnected and the approach was made hand flying the aircraft.

Title: AN AIRBUS 320 ON APCH TO 4000 FT WITH GEAR EXTENSION GOT MULTIPLE AURAL AND VISIBLE WARNINGS. NO ECAM CHKLISTS FOR REF. CAUSE UNKNOWN.

Narrative: FLYING ON AUTOPLT WITH AUTOTHROTTLE, INTERCEPTED LOC ON RWY 27L, THEN CALLED FOR GEAR DOWN. AS GEAR CAME DOWN, MULTIPLE NON PERTINENT AURAL AND VISUAL WARNINGS BEGAN GOING OFF. 'RETARD' PLUS GEAR AND CONFIGN WARNINGS WERE THE MEMORABLE ONES, WE WERE AT 4000 FT. ACFT APPEARED TO BE THINKING IT WAS IN FLARE MODE JUST ABOVE RWY. SPD DECAYED RAPIDLY AND WE WERE SIMPLY CONFUSED BY ALL THE DIFFERENT WARNINGS GOING OFF, SO I DISCONNECTED AUTOTHROTTLES AND AUTOPLT AND HAND FLEW PLANE OFF THE APCH TO AN AREA S OF FIELD TO INVESTIGATE WHAT WORKED AND WHAT DIDN'T. TRIAL GEAR RE-EXTENSION WAS NOT A PROB EXCEPT FOR RADIO ALTIMETER WARNINGS AT 4000 FT, I SHOULD NOT HAVE HAD THEM UNTIL ABOUT 3100 FT. MADE PAX ANNOUNCEMENT ABOUT EVENT. I DECIDED TO RETURN AND FLY ANOTHER APCH (STILL IN IMC WITH HIGH SURFACE WINDS) TO RWY 27L. DIFFERENT FLAP CONFIGN AND APCH MODE (VERT SPD VERSUS GS), BUT STILL GOT SAME EVENTS AT GEAR EXTENSION. THIS TIME I CONTINUED THE APCH AND TRIED TO IGNORE THE WARNINGS. THE PLANE WAS PERFORMING IN SPITE OF AURAL WARNINGS. VERY ROUGH APCH DUE TO HIGH WINDS. GOOD 'CLR' EXERCISE SINCE WE WERE GETTING MULTIPLE CONFUSING WARNINGS BUT WITH NO ECAM CHKLISTS TO FOLLOW. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE DIRECT CAUSE OF THE MULTIPLE WARNINGS IS UNKNOWN. THE RPTR SAID THE APCH WAS MADE IN HVY RAIN AND HIGH WINDS. THE RPTR STATED THERE WAS NO ECAM CHKLIST FOR THIS SIT. THE RPTR STATED THE AUTOTHROTTLE AND AUTOPLT WAS DISCONNECTED AND THE APCH WAS MADE HAND FLYING THE ACFT.
