Approximately 60 NM west if our destination at approximately 15;000 FT; we lost all data from both FMGCs. We tried unsuccessfully to restore any or all data; leaving us with no traditional electronic navigation. We had good ADI information; complete with speed; VSI and altitude information. Because of the late arrival and long duty day; coupled with the potential for complications; I elected to declare an emergency with Approach Control. We received a heading direct to the airport and flew a visual approach. We were able to use stand-by navigation for ILS information and good PAPI information. The approach and landing was otherwise uneventful. Company Dispatch; Maintenance and Flight Operations Duty Manager were notified.
Only ECAM was CABIN PRESS-set manual landing altitude. Lost all navigation ability. Lost all non-precision and non-precision ability. Declared emergency. Approach vectored us to a visual approach and normal landing. STBY NAV selected on Captain's RMP; course and frequency set. Glideslope appeared unreliable. Unable to reload any info back into FMGC using the MCDU.
While descending on an arrival; both A320 FMGCs failed causing lost precision and non-navigation data; so an emergency was declared followed by a visual approach. The RMP frequency and course were set; but the glideslope appeared unreliable and the only ECAM displayed was CABIN PRESS.
