ATC Simulator is a Claude skill that creates a realistic, text-based air traffic control game. It throws different situations at you, and you decide what to do.

What it looks like

An excerpt from a game at Stockholm Arlanda, playing the tower:

SK1417: “Cleared for take-off 19R, traffic Cessna in the circuit, Scandinavian 1417.”

+0:50

SK1417 starts its roll. The Cessna is turning base.

SE-MKL: “SE-MKL, base 19R.”

+1:25

Airborne. Then you see a smoke trail from the right engine. The aircraft yaws and climbs slowly.

SK1417: “Mayday, mayday, mayday, Arlanda Tower, Scandinavian 1417, engine failure, right engine, passing 600 feet, continuing straight ahead. Request return and landing 19R. We need a few minutes. Stand by.”

FIN7XA is on 5 NM final and SE-MKL is on base, about 1 minute from final.
1010Z | Wind 190/09 | QNH 1013 | RWY 19R ARR/DEP (19L closed)
SK1417 A320 IFR MAYDAY, R engine failure, 600 ft, straight ahead wants to return to 19R
