Realistic Takeoff - Immersive Aircraft

ENGINE SPOOL AND RUNWAY TIMER FIX

- The minimum runway timer no longer begins from throttle input alone.
- Aircraft may now take as long as needed to spool their engines while the HUD remains in the Ready stage.
- The runway timer begins only after the aircraft reaches measurable forward movement.
- Slow-accelerating aircraft now receive their full selected runway roll after they actually begin moving.
- The runway timer pauses if the aircraft bogs down below rolling speed.
- Small early wheel bounces no longer advance the runway timer.
- An aborted takeoff resets after the throttle is cut and the aircraft nearly stops.

- Adaptive takeoff behavior for different aircraft statistics and payloads.
- Progressive runway roll, rotation, liftoff, and initial-climb stages.
- Smooth pitch authority and lift blending during takeoff.
- Slow-aircraft fallback and normal-flight handling restoration.
- Balanced, Realistic, and Cinematic presets.
- Configurable HUD and takeoff physics settings.
- Compatible aircraft from Immersive Aircraft add-ons remain supported.
