Narrative:

During the descent portion of the flight into ZZZZ the following ECAM faults appeared: hydraulic green system low pressure and green system hydraulic reservoir low level. I was flying. I continued to fly the arrival and navigation around some rain showers in the area while the first officer performed the ECAM procedures. This was followed by a review of the status page. The decrement chart was referred to for the loss of green hydraulic system; and landing distance was calculated. The loss of brake memory items were reviewed for a worse case scenario. A manual gear extension was performed per the checklist. ATC was advised of the possibility of needing the entire length of the runway. A normal approach to a landing was accomplished. After touchdown I tapped the brakes to ensure the alternate system was functioning properly. We cleared the runway without incident.

Title: AN A320 EXPERIENCED A GREEN SYSTEM HYD FAILURE ON APPROACH TO DESTINATION.

Narrative: DURING THE DSCNT PORTION OF THE FLT INTO ZZZZ THE FOLLOWING ECAM FAULTS APPEARED: HYD GREEN SYS LOW PRESSURE AND GREEN SYS HYD RESERVOIR LOW LEVEL. I WAS FLYING. I CONTINUED TO FLY THE ARR AND NAV AROUND SOME RAIN SHOWERS IN THE AREA WHILE THE FO PERFORMED THE ECAM PROCS. THIS WAS FOLLOWED BY A REVIEW OF THE STATUS PAGE. THE DECREMENT CHART WAS REFERRED TO FOR THE LOSS OF GREEN HYD SYS; AND LNDG DISTANCE WAS CALCULATED. THE LOSS OF BRAKE MEMORY ITEMS WERE REVIEWED FOR A WORSE CASE SCENARIO. A MANUAL GEAR EXTENSION WAS PERFORMED PER THE CHKLIST. ATC WAS ADVISED OF THE POSSIBILITY OF NEEDING THE ENTIRE LENGTH OF THE RWY. A NORMAL APCH TO A LNDG WAS ACCOMPLISHED. AFTER TOUCHDOWN I TAPPED THE BRAKES TO ENSURE THE ALTERNATE SYS WAS FUNCTIONING PROPERLY. WE CLRED THE RWY WITHOUT INCIDENT.
