Narrative:
We were on a flight to alb in scattered clouds and thunderstorms. On approach, the WX at alb was reported as scattered at 3000 ft and 10 SM of visibility. We were cleared to descend from 5000 ft to 2000 ft. I initiated the descent when we were given a vector to intercept the localizer and cleared for the approach. As the autoplt began the turn, I armed the approach function of the autoplt. Our final turn allowed a 40 KT tailwind to blow us through the localizer. The autoplt captured both the localizer and GS. At full deflection the autoplt then released the localizer, but remained captured to the GS. We then descended below the 2000 ft altitude assigned. I selected the altitude capture function at 2000 ft, but the airplane finally leveled at approximately 1700 ft. We had the airport in sight at that time and made a safe visual approach and landing. There was no conflict with other traffic or terrain. Supplemental information from acn 620601: we were in VMC with the runway in sight and an approach clearance, so I didn't correct the captain on the altitude assignment. The controller queried us about our altitude being lower than assigned. I responded that we were VMC. My rationale is that we could descend at our discretion when in a normal descent profile and runway in sight even though the localizer was still full scale. I do not know if this is correct or not. The controller seemed somewhat annoyed, but did not ask for a phone call.

Title: CARJ LNDG ALB DSNDED BELOW ASSIGNED ALT AND CROSSED LOC WHILE EXECUTING ILS RWY 19 APCH.
Narrative: WE WERE ON A FLT TO ALB IN SCATTERED CLOUDS AND TSTMS. ON APCH, THE WX AT ALB WAS RPTED AS SCATTERED AT 3000 FT AND 10 SM OF VISIBILITY. WE WERE CLRED TO DSND FROM 5000 FT TO 2000 FT. I INITIATED THE DSCNT WHEN WE WERE GIVEN A VECTOR TO INTERCEPT THE LOC AND CLRED FOR THE APCH. AS THE AUTOPLT BEGAN THE TURN, I ARMED THE APCH FUNCTION OF THE AUTOPLT. OUR FINAL TURN ALLOWED A 40 KT TAILWIND TO BLOW US THROUGH THE LOC. THE AUTOPLT CAPTURED BOTH THE LOC AND GS. AT FULL DEFLECTION THE AUTOPLT THEN RELEASED THE LOC, BUT REMAINED CAPTURED TO THE GS. WE THEN DSNDED BELOW THE 2000 FT ALT ASSIGNED. I SELECTED THE ALT CAPTURE FUNCTION AT 2000 FT, BUT THE AIRPLANE FINALLY LEVELED AT APPROX 1700 FT. WE HAD THE ARPT IN SIGHT AT THAT TIME AND MADE A SAFE VISUAL APCH AND LNDG. THERE WAS NO CONFLICT WITH OTHER TFC OR TERRAIN. SUPPLEMENTAL INFO FROM ACN 620601: WE WERE IN VMC WITH THE RWY IN SIGHT AND AN APCH CLRNC, SO I DIDN'T CORRECT THE CAPT ON THE ALT ASSIGNMENT. THE CTLR QUERIED US ABOUT OUR ALT BEING LOWER THAN ASSIGNED. I RESPONDED THAT WE WERE VMC. MY RATIONALE IS THAT WE COULD DSND AT OUR DISCRETION WHEN IN A NORMAL DSCNT PROFILE AND RWY IN SIGHT EVEN THOUGH THE LOC WAS STILL FULL SCALE. I DO NOT KNOW IF THIS IS CORRECT OR NOT. THE CTLR SEEMED SOMEWHAT ANNOYED, BUT DID NOT ASK FOR A PHONE CALL.
