No request, registration, private GitHub access or payment is required to
download the source. All URLs below are served by this website.
The machine-readable list /licenses/source-files.json lists each file.

Original flightdeck model, textures, copyright and GPL text:
  /models/flightdeck/fd_complete.ac
  /models/flightdeck/README.copyright.md
  /models/flightdeck/LICENSE-GPL-2.0.txt
  /models/flightdeck/provenance.json
  All original texture files remain alongside the model.
Original landing gear geometry, XML hinge/door tables and textures:
  /models/gear-articulated/source/ (individual URLs in source-files.json)
  /models/gear-articulated/source/revision.json
  /models/gear-articulated/source/README.copyright.md
  /models/gear-articulated/source/LICENSE

AirplaneInWeb conversion tools (provided under GPL-2.0-only):
  /licenses/source/scripts/convert-flightdeck.mjs
  /licenses/source/scripts/prepare-landing-gear.mjs
  /licenses/source/scripts/build-articulated-gear.py
Extracted hinge data:
  /licenses/source/src/world/gear-rig.json

Rebuild in a local directory using the following layout:
  scripts/                    downloaded conversion tools
  public/models/flightdeck/    downloaded original model and textures
  public/models/gear-articulated/source/  downloaded original source files
  src/world/                  create this output directory
Use Node.js 24 and Blender 5.2 (the tool versions used for conversion).
From that directory:
  node scripts/convert-flightdeck.mjs
  blender --background --python scripts/build-articulated-gear.py
No npm packages are required by these converters; Blender provides bpy.
prepare-landing-gear.mjs optionally downloads the pinned source then runs
Blender. It is not required when the original source has been downloaded.

Changes: AC3D triangulation, regenerated normals, axis alignment, static glTF
conversion, optional cockpit HUD/visor removal, landing gear mesh separation
and extraction of hinge/door tables. Original texture images are retained.
Original geometry is not Airbus-certified CAD. Models are not FlightGear
simulator code; cockpit instruments are static. Generated glTF/bin and
derived hinge data remain GPL-2.0-only. This notice does not relicense
independent map data, the CC BY exterior, or unrelated application code.
No warranty is provided; see the GPL text for the complete terms.
