FlyingIron Simulations – Spitfire L.F Mk IXc v1.4.2

– Flight Model Updates:
– Introduced new wing airfoil lift coefficient profile
– Corrected control surface area sizes
– Rebalanced forces across all axes
– Implemented a new suspension system
– Adjusted aeroplane geometry for improved accuracy
– Retuned control surface elasticity tables
– Doubled CFD resolution for enhanced precision
– Retuned adverse yaw behaviour
– Updated Mach table based on Spitfire-specific data
– Introduced a new ground effect table
– Adjusted control surface input scaling and effectiveness data
– Fine-tuned engine torque and gyro precession setup

– Vibration System:
– Running changes to the vibration system are intended to increase the quality of the simulation as well as fidelity. As the system advances, there is increasingly more user feedback going beyond the purely visual realm. The most recent changes include:

– Introduced new vibration code for smoother animations, computed per frame for consistent performance regardless of FPS

– Sources of vibration now include:
– Static thrust turbulence (high power, low speed, on the ground)
– Ground interaction (g-forces, bumps, and landings)
– RPM range smoothness (smooth around 2100-2400 RPM, rougher outside this range)

– Added vibrations to:
– Rudder and elevator
– Throttle and wobble lever
– Control column and rudder pedals

– Refined vibration algorithms for improved realism

– Propeller and Ground Physics:
– Smooth propeller animation now calculated per frame
– Added multiplayer propeller support using Beacon Light 2
– Improved taildragger physics core, based on Fw190 and customised for the Spitfire
– Customised tailwheel animation to align with airflow during slips and drops forward during noseover
– Enhanced ground loop algorithms for better differentiation between landing and takeoff conditions
– Refined suspension behaviour to match observed performance
– Improved propwash steering and differential brake steering algorithms
– Reduced ground effect and refined ground physics for smoother transitions

– Drag and Performance Tuning:
– Fine-tuned drag coefficients to meet top speeds accurately
– Increased elevator trim authority
– Balanced overall flight characteristics, maintaining known snap roll behaviour
– Retuned flap behaviour to match official specifications (flap up cLmax: 1.36, landing cLmax: 1.80)
– Adjusted propeller drag to align with expected approach parameters
– Implemented new propeller and cD0 data
– Fine-tuned high-speed behaviour up to 0.89 Mach

– Buffeting and Vibration Refinements:
– Introduced new Lvar “Buffeting”
– Enhanced buffeting logic, now accounting for speed and amplitude variations
– Added 4Hz buffeting cockpit camera vibrations
– Optimised buffeting and vibration algorithms

– VR and Camera Improvements:
– New organic camera setup considering head/neck rotation and eye position
– Tweaked VR pilot camera position
– Retuned vibrations for VR compatibility
– Improved ground handling and roll sensitivity in VR

– Miscellaneous Updates:
– Consolidated and refactored exterior.xml for improved performance
– Retuned control surface reactivity to match real-world aerobatic responses
– Adjusted stall behaviour for better aileron control during stalls
– Refined drag for open canopy, open radiator, and slipper configurations
– Improved slip coordinator using Incidence Beta SimVar

Designed by Supermarine to be a short-range, high-performance interceptor, the Spitfire is most famous for it’s pivotal role in World War II & The Battle of Britain where it was a key weapon against Axis forces. Instantly recognizable by it’s iconic elliptical wing, the Spitfire needs little introduction from us.

Features:

• 3D Cockpit Model built from Heritage Flight Simulations incredibly detailed CAD Model
• The model is a perfect replica of the Spitfire Mk IX cockpit, down to the smallest detail, and is used for the production of HFS’s amazing cockpit replica.
• This is of course backed up by our usual ultra-high Artwork standards across the entire aircraft – the in-game screenshots say more here than we ever could! Combined with the gorgeous scenery of MSFS, prepare to be blown away by just how good an old legend can look inside a modern simulator.
