A320
Aircraft Equipment Problem Critical
Flight Crew Returned To Departure Airport; General Declared Emergency
Aircraft
Aircraft had a deferred item: 'SFCS 2 Flap Channel.'On climbout; at approximately 25;000 FT; the following warnings and cautions were observed: Warning--Auto Flt AP Off; Caution--F/CTL Flaps Locked-Wing Tip Brk On; Slat Sys 1 Fault; Auto FLT A/THR Off. The following systems were inoperative: Autopilot 1; 2; Autothrust; Flight Director; Speed Warnings; indications and flaps. ECAM and QRH actions accomplished. We declared emergency with ATC and coordinated return to our departure airport with ATC. After troubleshooting; we configured for landing with flaps selected 3; actual flap position was 0; actual slat position was 2. QRH landing speed and distance additives were applied. Landed safely on Runway X at our departure airport. Flap system failure was likely related to MEL.I suggest we should re-evaluate whether maintenance procedures for releasing aircraft with MEL 27-51-01A are adequate.  Secondly; we should train for 0-Flap landings without use of autopilot; Flight Director; or autothrust.
Dispatched with a deferred flap channel fault the flight crew of an A320 received multiple system fail warnings including locked flaps during the climb.  They declared an emergency and returned to their departure airport landing with zero flaps and slats at position 2.
