On our approach we got a momentary GPWS warning when leveling off at ATC cleared altitude of 3;000 [feet]. The captain disconnected the autopilot and was getting ready to perform the escape maneuver when the warning stopped. We were able to see the terrain and the airport and [we were] above the published approach altitude so we determined it was safe to continue approach.
Cleared direct to PENNA Intersection on the ILS to Runway 06 with a descent clearance to 3;000 feet. At approximately 3;300 feet with autopilot engaged and in ALT; we received a single 'Terrain' warning. I disengaged the autopilot and began the escape maneuver with no other warning or commands. We had the airport in sight and were in VFR conditions; but it was at night. We never received a 'Terrain; Terrain' warning or any other commands; just the single aural Terrain command. We crossed PENNA at 3;300 [feet] with a descent to 2;400 [feet] at the JANID Intersection where we captured the glide slope and continued to a normal approach and landing.
A319 flight crew reported a GPWS warning while executing a visual approach on autopilot. Crew disengaged autopilot and executed the approach manually.
