For years, Flight Simulator X (FSX) lacked a dynamic ground handling environment. Default aircraft would sit on empty tarmacs, or magically disappear and reappear at gates. FSDreamTeam’s GSX (Ground Services X) aimed to solve this by bringing the airport environment to life. The version 1.x series (such as the 1.9 builds) represents the mature, stable iteration of this classic add-on before the release of GSX Level 2.
