stands for Aircraft Flow Library . It is a plugin framework designed for X-Plane 11 that standardizes how checklists and procedures are displayed and interacted with. Unlike static PDF checklists or the default X-Plane checklist system, AFL integrates directly into the 3D cockpit or a pop-up window.

Unlike generic libraries that serve multiple developers, the AFL Library is to Airfoil Labs products.

The AFL Library (RA_Library) is a critical asset for X-Plane 11, providing high-resolution textures, weathered surfaces, and specialized markings that significantly enhance visual realism. As a widely adopted dependency for numerous scenery packs, this optimized library acts as a foundational, "must-have" enhancement for simulating realistic airport environments in the simulator.
