Flight Simulator Aircraft Configuration (CFG) is a plain text settings format developed by Microsoft for use within the Microsoft Flight Simulator franchise. It utilizes a structured initialization syntax to define essential aircraft parameters, including flight dynamics, visual model references, and cockpit gauge layouts. While inherently safe to view and edit using standard text editors, incorrect modifications to configuration variables can result in simulation instability or aircraft loading failures.
