Narrative:
We were cleared for the approach to runway 23L, but contacting tower on a 10 mi final, were asked if we could proceed visually to runway 23R, with a caution that the approach end was obscured by blowing dust. We were attempting to visually transition to runway 23R, when I, as PF, delayed my call for gear extension. Approaching 1000 ft above field elevation, with runway 23R in sight, I asked for the gear and final descent checklist. My call for gear extension was late, and contrary to stabilized approach guidelines. We were slowed to near approach speed, and the approach was fully stabilized at 500 ft above field elevation, and we continued the approach for an uneventful landing, on speed and in the touchdown zone. The gear, however, was extended late, owing primarily to my distraction while trying to acquire runway 23R for a visual approach. The ECAM for 'gear' sounded briefly at 800 ft AGL as the gear was in transit. SOP dictates a missed approach under these conditions, but I continued the approach to landing. I was a bit behind the aircraft, and should have gone around.

Title: AN A320 FLC ACCEPTS A LAST MIN RWY CHANGE THAT RESULTS IN A NON STABILIZED APCH TO LNDG.
Narrative: WE WERE CLRED FOR THE APCH TO RWY 23L, BUT CONTACTING TWR ON A 10 MI FINAL, WERE ASKED IF WE COULD PROCEED VISUALLY TO RWY 23R, WITH A CAUTION THAT THE APCH END WAS OBSCURED BY BLOWING DUST. WE WERE ATTEMPTING TO VISUALLY TRANSITION TO RWY 23R, WHEN I, AS PF, DELAYED MY CALL FOR GEAR EXTENSION. APCHING 1000 FT ABOVE FIELD ELEVATION, WITH RWY 23R IN SIGHT, I ASKED FOR THE GEAR AND FINAL DSCNT CHKLIST. MY CALL FOR GEAR EXTENSION WAS LATE, AND CONTRARY TO STABILIZED APCH GUIDELINES. WE WERE SLOWED TO NEAR APCH SPD, AND THE APCH WAS FULLY STABILIZED AT 500 FT ABOVE FIELD ELEVATION, AND WE CONTINUED THE APCH FOR AN UNEVENTFUL LNDG, ON SPD AND IN THE TOUCHDOWN ZONE. THE GEAR, HOWEVER, WAS EXTENDED LATE, OWING PRIMARILY TO MY DISTR WHILE TRYING TO ACQUIRE RWY 23R FOR A VISUAL APCH. THE ECAM FOR 'GEAR' SOUNDED BRIEFLY AT 800 FT AGL AS THE GEAR WAS IN TRANSIT. SOP DICTATES A MISSED APCH UNDER THESE CONDITIONS, BUT I CONTINUED THE APCH TO LNDG. I WAS A BIT BEHIND THE ACFT, AND SHOULD HAVE GONE AROUND.
