Vice is an air traffic control simulator, focused on TRACON. It presents a STARS-like interface, but with simulated traffic and other controllers. It also supports multiple users, where each person controls a different position at a facility.
Vice supports departure and arrival control scenarios in numerous TRACONs and ATCT/TRACONs, currently: A11, A80, A90, AAC, ABE, ABQ, AGS, ALB, ASE, AUS, AVL, BGR, BHM, BIL, BNA, BOI, BTV, BUF, C90, CHS, CID, CLE, CLT, COS, CPR, D01, D10, D21, DAB, EWR, F11, GSO, GSP, GTF, I90, IND, JAX, L30, M98, MCI, MDT, MIA, MKE, N90, NCT, OKC, P31, P50, P80, PCT, PHL, PIT, PVD, PWM, R90, RDU, S46, S56, SAV, SBA, SBN, SCT, SDF, SGF, SYR, TPA, and Y90. New scenarios are regularly added.
