During climbout we had an LGCIU #2 failure and completed the QRH procedure and reference actions for the failure. Enroute we requested and received landing data and determined no issues existed with our planned landing. On descent through approximately 8;500 feet MSL for landing at the Captains (PF's) direction I placed the landing gear handle in the down position with no resulting gear extension. We completed the ensuing ECAM and QRH procedures for the L/G Gear Not Down Locked event without success and accomplished a go around. The go-around was normal considering the aircraft configuration. Established on a downwind we successfully accomplished the L/G - Gravity Extension QRH procedure; declared an emergency due to the loss of nose wheel steering capability; and completed a normal approach and landing with approximately 4;000 FOB.
At cruise the LGCIU #2 ECAM appeared. On final approach when landing gear was selected down nothing happened. Following ECAM procedure the landing gear handle was recycled; with no effect. We went around. On downwind we manually extended the gear and got three green indications. Landed normally and cleared the runway at the high speed turnoff and stopped (No nose gear steering). Tug came and towed us to the gate.
A320 flight crew reports failure of LGCIU Number 2 in cruise. During approach the landing gear fails to extend when selected; and the gear handle is cycled to no avail. A go-around is initiated and the landing gear gravity extension procedure is followed successfully extending the gear.
