The game simulates a wide array of airport tasks, including aircraft guiding, marshalling, securing aircraft, connecting ground power units, fueling, luggage handling, and jetway operation. It features true-to-life airports such as Vagar, Keflavik, Warsaw Chopin, and Key West, all meticulously recreated with accurate ground layouts and parking configurations. Players can operate licensed aircraft like the Airbus A320neo and 737 MAX, alongside partnered airlines, and utilize a variety of licensed ground vehicles with realistic physics and interior models. The simulation incorporates a detailed weather system synchronized with the METAR system, and provides multiple gameplay modes: Scenario, Challenge, Cooperation, and Free Play.
