Legacy exterior and native JSBSim FDM:
FGMEMBERS/A380, commit 715e972134a2a708115419d2d301b14e8323922a
https://github.com/FGMEMBERS/A380/tree/715e972134a2a708115419d2d301b14e8323922a
GPL version2, COPYING preserved in A380/COPYING. Original contributor names and file headers retained.

New cockpit only:
scotth1/A380, branch V2.0-newmodel, commit c68364ace6303f366a8242fb19b34d4f95a45da9
https://github.com/scotth1/A380/tree/c68364ace6303f366a8242fb19b34d4f95a45da9
Models/FlightDeck/flightdeckV2.xml explicitly states Copyright Toryx2014 and distribution under GNU GPL version2. Preserve exact original header and associated AC/textures. Repository README calls this model work in progress. The new exterior is not used.

Application adaptation:
The newer cockpit is translated rigidly by scene[2.642,-5.87,-17.43] relative to imported source transform, matching legacy captain eye; FOV82. Original cockpit includes true side-stick/throttle/pedal mesh objects. Application animation pivots and control bindings are documented separately in flight-src/A380_CONTROL_ADAPTATION.json. These are derived adaptations, not upstream finished animations.

Fidelity:
The A380_RJ native source, genuine source Nasal startup payload and original aerodynamic coefficients are retained. Application control range and coach deceleration were corrected. Full-route native regression passed (A380_SOURCE_VALIDATION.json); neither the community model nor this regression is manufacturer certification.
