Below is a list of changes coming in this update. Below are not all changes, but those listed while this core update was in testing. Since we are in parallel development with other aircraft, some changes effect the existing Spitfire I/II on the market today, others do not, so we categorized them as such below for your convenience.

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)

Just run this over any accusim spit installation.

Scott.

Pure awesomeness is all I can say.

Well that's not strictly true, because there's a lot I'd like to say. I'll keep it short though.

The main thing I want to say is, THANK YOU. I do love your update videos, I could watch them for hours. You have done amazing work on the beautiful spitfire, and the update just makes it better and better. Well done A2A (that's everybody involved), I for one really appreciate all your hard work. Once again, thank you all

Thank you very much, A2A, unbelievable that "perfect" things can improved even more by yours
AND- thank you for beeing a "rare one" publisher/SW Group, who makes things done as you promised- and beyond- thats sadly not the ´normal way´ today!!

a really loyal and proud A2A fan

WOW!!! Amazing!!! "Airframe Physics and Harmonics" The immersion meter just went BONKERS!!!!!!

Thank You for making the video,Can't wait to try out the update on the Spitfire.

I get such a kick out of watching Scott point things out in the video. Mainly because I try and show things like that to my family and they just yawn and walk away where as I'm watching him on the video thinking, COOL!!! That being said, thanks for the great update Scott. We all really appreciate what you do.

You know I have exactly the same problem ! I turn around and the family have left mid video. Ah well at least I appreciate watching.

Cheers for the update Scott. I do enjoy your honest "nuts and bolts" style of videos pointing out the details and explaning why things work the way they do.

Great!

Are LG and Samsung made by the same company? Because the monitor looks identical to my LG...

Will any of this eventually filter down to the B-17?

Think of each product as a bucket, and 65hp J-3 Cub's bucket is the same size as a Boeing 377 Stratocruiser's. Each project pretty much pushes things to the saturation point.

If you looked in the Cub bucket, you would see a lot of flight physics, water physics, etc. For the 377, you would see a lot of passengers, a crew, captain, etc. If we went back into the B-17 and started to cram in support for every single spark plug in all four engines, we would be pushing something out, like the radio, active crew, etc.. Each plane is its own bucket with unique things.

The existing core Accu-Sim tech is for single-engine aircraft atm and this will carry through to the F-104. When we do the Phantom, we will then move to multi-engines.

Downloading now!!
Thank You

Thanks for the update!

But before installing the update I would recommend to make a backup of the aircraft.cfg. That makes it easier to copy the [fltsim] entries for the repaints back into the updated aircraft.cfg

Greetings
Tim

Downloaded and Installed Thanks guys.
Accomplished my first flight (St Athan to Jersey, my home base) without burning up my engine Quite chuffed !
Being a noob, I forgot to back up the Aircraft cfg. and lost a few re-paints. Just in case anyone else forgets.

Tim,

Good point. We just now updated the installer with a little aircraft.cfg backup routine. Nothing else has changed but this will at least help those who download it now and after to not lose their paints.

Scott.

Downloaded and test flown up the Pacific Coast (ORBX). Made it without overheting

Thank You Scott for this update!
