Narrative:

10 east of ard VOR at 11000 ft, ATC issued advisory traffic 12 O'clock and 10 NM. It was hazy. Shortly after, we got a TA from TCASII. No visual contact. It showed 400 ft below. Approximately 5 NM or so we got an RA from TCASII to climb 1500/2000 FPM. We commenced a climb and told ATC. At 11400 ft monitor vertical climb and we leveled off at 11500 ft. Traffic was in sight at approximately 2 to 3 NM after the RA. ATC then cleared us back to 11000 ft.
