Narrative:
ATC facility, ny approach control. Location, dny/V483. Over flips intersection on V483. At 6000 ft in contact with ny approach control was given heading 140 degrees and descent to 4000 ft. During descent at approximately 5500 ft we received a GPWS terrain warning. Our descent rate at the time was 1000 FPM. Copilot flying disconnected the autoplt and immediately started climb. The GPWS warning stopped. We told ATC that we were responding to the warning. We were then given a heading of 210 degrees and further descent to 3000 ft. No traffic conflicts. Both pilots wonder if this was actual terrain conflict or possible malfunction of GPWS. Landed VFR without incident. I felt that original route filed and cleared from intersection to airport without navaids at night, and at the time IMC, is unnecessary. Another difficulty adding to the situation was a ny controller with a heavy hispanic accent. Could it possibly help to at least have VFR sectional charts above mountainous areas?

Title: GPWS SOUNDS DURING DSCNT. PLT STOPS DSCNT AND BEGINS CLB. RPTR CLAIMING POSSIBLE FALSE ALARM.
Narrative: ATC FACILITY, NY APCH CTL. LOCATION, DNY/V483. OVER FLIPS INTXN ON V483. AT 6000 FT IN CONTACT WITH NY APCH CTL WAS GIVEN HDG 140 DEGS AND DSCNT TO 4000 FT. DURING DSCNT AT APPROX 5500 FT WE RECEIVED A GPWS TERRAIN WARNING. OUR DSCNT RATE AT THE TIME WAS 1000 FPM. COPLT FLYING DISCONNECTED THE AUTOPLT AND IMMEDIATELY STARTED CLB. THE GPWS WARNING STOPPED. WE TOLD ATC THAT WE WERE RESPONDING TO THE WARNING. WE WERE THEN GIVEN A HDG OF 210 DEGS AND FURTHER DSCNT TO 3000 FT. NO TFC CONFLICTS. BOTH PLTS WONDER IF THIS WAS ACTUAL TERRAIN CONFLICT OR POSSIBLE MALFUNCTION OF GPWS. LANDED VFR WITHOUT INCIDENT. I FELT THAT ORIGINAL RTE FILED AND CLRED FROM INTXN TO ARPT WITHOUT NAVAIDS AT NIGHT, AND AT THE TIME IMC, IS UNNECESSARY. ANOTHER DIFFICULTY ADDING TO THE SIT WAS A NY CTLR WITH A HVY HISPANIC ACCENT. COULD IT POSSIBLY HELP TO AT LEAST HAVE VFR SECTIONAL CHARTS ABOVE MOUNTAINOUS AREAS?
