The A2A Simulations Community

We appear to be close to the release our first core Accu-Sim Update (v1.1).

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)

Thanks for the update Scott.
Can't wait to read more about the next models.

Hi Scott,

this sounds really great! "excessive bearing wear fixed": Has the excessive wear of the cylinders also been fixed?

Looking forward to this one.

Best regards
E.

The more, the better, keep it up.

I can't wait to fly that accu-sim'd 104. Great to see that you guys are constantly upgrading accu-sim.

Awesome! I love it when a good thing gets even better

That's incredible. Almost all of the bugs / difficulties discussed on the forums are on that list!

A few minor changes were just made so we're making a new build. Earliest it would be released is the end of this week.

Scott.

No, Boon is correct, there is a little bug in the B-17 we fixed and have to get out to the public.

Great to see this progress. I can't wait for the P-51D...and the F-104C...and the F-4whatevervariant.

Looking forward to the Accusim update!

Quick question, and I'm not trying to push A2A, as I know they are working incredibly hard to bring us the best products available, and I don't mind waiting: I was just wondering if a major new release (ie P-40 or P-51) could be expected by Christmas, or if we are looking further down the road? (If I missed this in another thread apologise.) I understand that develpoments are constantly evolving and there may be no known time frame yet, I was just hoping for a ball park guess to wet the appetite!
