We have an Accu-sim technology update which includes a Spitfire update



Video;





Changes affecting Spitfire MKI/II
- While Accu-Sim ignores the default FSX electrical system, we changed the FSX electrical system from 24v to 12v in aircraft.cfg for continuity
- New engine oil and coolant algorithms representing internal mass inertia and coolant flow passing through a large engine. This means the engine can be quicker to heat up and slower to cool down.
- MkI flaps warning says 160 MPH instead of 140 MPH
- MkII cockpit: flaps warning says 160 IAS; maximum speeds converted to MPH
- New trigger for the MkI
- Aircraft.cfg atc_type=Supermarine
- Added additional physics to airframe vibrations. Vibrations are both more precise and dynamic
- Slightly lowered shake effect on our manifold pressure gauge
- Engine fire logic re-coded. Engine fires start based on high temps, eng cyinder condition, and engine oil system condition (representing oil outside of engine)
- Engine oil consumption increased. Can be as high as 4gph with a very worn engine (past TBO), not including leaks
- Brighter, weathered windshield screws to match existing worn cockpit
- RPM value that was feeding to FSX was reversed on the 2-speed prop. Accu-Sim was compensating for this, so changes should not be very noticeable, but working numbers are more consistent
- Engine remembers if it was running before exit
- Elevator and rudder trimwheels animation: 4 turns for full work range
- Fuel tanks on spit upgraded to new standard, should scale accurately with pitch changes
- Fixed gear collapsing bug
- Radiator flap positions changed to: 1. Closed/guns warming, 2. Normal flight, 3. 1/4 open, 4. 2/4 open, 5. 3/4 open. 6. Fully open
- New, less bluish glass
- Fuel gauges tooltips don't read any value when buttons are not pressed
- Runway thumps
- Removed A2A_Spit.dll
- Fixed error with low RPM combustion firing
- New physical fuel pressure physics. You can see this at very low RPM (when engine is cranking or winding down)
- New supercharger code module (supports multiple stages, draw, efficiency, and efficiency changes with different air pressures). Simply allows Accu-Sim to better simulate supercharged performance in all air conditions
- Removed files from aircraft panel folder that were moved to central folder
- Excessive bearing wear on startup and shutdown fixed
- Adjusted fuel delivery impact on engine combustion
- Smoother prop sounds for startup and shutdown when canopy is opened
- New "plastic" seat for the MkII
- Coolant overtemp relief valve blows roughly 1/10 gal per min
- Some texture and bump improvements
- Come copper internal components replaced with brass
- Removed default fuel pump sounds from spitfire sound.cfg's

Multiplayer
- Multiplayer propeller visibility and rotation issue
- Landing flaps animation should be visible in MP
- Possible fix for the trolley and wheel chocks MP visibility issue.
- Disabled and renamed cartridge starter visual effect due to multiplayer error



Changes only affecting other aircraft in development
- Electrical system standardized to support all aircraft
- Electrical prop system added (P-40 Curtiss Electric prop)
- Electric prop does not draw electricity when at the stops
- Added drag system to P-40
- Fixed an issue with the wobble pump and fuel pressure
- Electrical voltage outputs set for each aircraft
- Initial P-51 cockpit sounds added (P-51)
- Fuel sloshing physics
- RPMGaugeSwayPhysics customizable for each aircraft
- Completed hydraulic system including actuator support for drooping gear doors in P-51
- New ground bump physics added
- RAM air and Carb heat systems implemented
- Engine piston suction bug fixed
- Oil dilution support added
- Inertia starter support (P-40)
- Manifold Pressure Regulator support (P-51)
- Oil cooler flaps (P-51)
- Automatic coolant and oil cooling systems (P-51)
- Electric fuel primer support (P-51)
- Hydraulic and Pneumatic brakes, flaps, and gear system support
- Initial turbo-jet engine physics modeling and sound module added (F-104)
- Manual wobble pump support (P-40)


Please see our forums for further details details; http://a2asimulations.com/forum/viewtopic.php?f=23&t=26794 and feel free to comment.


And here we are in one of our older videos, doing a P40 walaround with the great guys at Cavanaugh Flight Museum in Dallas Texas.


Cheers,

Thanks for the heads up, good to see you guys keep pushing the realism. I'll be firing up the old Spitfire tonight with the 1.1 patch. smile

Me, two, just downloaded.

Now if you guys would just do a Stearman. (WW2, and available for all that "Acusim" type recording and such, right?) smile
