The flight model's longitudinal force/speed-command accumulator and the accel/brake trigger command are stepped by fixed per-frame constants with no delta, so with ac6_unlock_fps active the plane accelerates and brakes proportionally faster at higher frame rates. Wrap the two flight-model functions (rex_sub_823046A0 force step, rex_sub_82329B40 input shaping) and rescale each accumulator's net per-call change by frame_time / 33.3ms, reproducing the native 30fps continuous-time dynamics at any frame rate. Bit-exact pass-through at <=30fps; applies to player and AI aircraft. Gated by ac6_fps_physics_fix (default on) and only active while the unlock's timing hooks are (ac6::TimingHooksActive).
