Aircraft
On a vector to intercept localizer; both FMGC's dropped all data and we lost NAV radios; maps; cabin pressure controller and managed speed. Declared emergency; took vectors to work the problem. First Officer emailed Dispatch looking for VFR. I manually inserted the ILS into the RMP; got a good ident; depressurized the aircraft; and flew an ILS with selected speed to a normal landing.
Approach assigned a turn off the arrival; vectoring for the ILS at 4;000 FT in IFR conditions. With turn to heading; I saw that my display now said map not available. I checked and saw that Captain's display also said map not available. Neither FMGC displayed navigation information. Then ECAM alarmed Cabin Landing Elev not set - use manual pressurization. We asked for vectors off approach to try to investigate situation. ACARS to Dispatch for closest VFR weather; Captain asked ATC for weather at nearby airports and declared Emergency Aircraft. Manually tuned ILS available on Captain's radio and set inbound course. [We] received good ident and DME asked for vectors to ILS. Manually depressurized aircraft to landing elevation; used selected speeds for approach and landing.
A320 flight crew reports dual FMGC failure during approach in IMC. The ILS frequency is successfully tuned using the RMP and the flight lands at destination after manually depressurizing the aircraft.
