QUESTIONS:

My download speeds are slow?
Our servers are working fast 99.9% of the time (the same ones that house our online store), and if speeds at your location is slow, this means the slow down is not at our servers but somewhere between our servers and your location. The first time you run the update, it may download a few hundred megabytes of data (still less than our previous single large zip file). However, all future update will be smaller, so any long downloads now should be a one time experience.

My flight sim computer is offline. How do I get the updates?
In today’s world it’s becoming increasingly difficult to have any computer device not having Internet access. So we highly recommend you do whatever is necessary to get Internet access to your flight sim computer. However, if for whatever reason you just cannot get Internet access to your flight sim computer, follow the directions below:
1. Plug a USB drive into your offline flight simulator
2. On the USB drive, create a new folder called “FSX_Update"
3. Find the folder that FSX is installed and copy the following files to the "FSX Update" folder on your USB drive:
- fsx.exe (or prepar3d.exe for p3d users)
- A2A folder with all contents
- SimObjects \ Airplanes \ [any A2A aircraft] folders with all contents
- Create a Gauges folder and just copy the A2A_Accusim.dll to this folder
P-47 owners ONLY:
- Gauges [add any files or folders starting with "WoP3_P47...]

4. Once completed, you should see four objects: A2A, SimObjects, and fsx.exe (P-47 owners will have a GAUGES folder too)
Image

5. Plug the USB drive into the online computer, then download and run the "A2A Update" then BROWSE for "FSX_Update" folder
6. Once completed, plug the USB drive into the offline flight simulator computer
7. Copy / paste the contents to your FSX installed directory, overwriting what is there

- Starter amps adjusted (should be lower than before)
- Maintenance hangar will warn a bit earlier about aging oil, air, and fuel filters
- Improved engine behavior when leaning. Carbureted engines will be rougher earlier than fuel injected due to less precise mixture distribution. A fuel injected engine has more uniform air/fuel distribution, and will be able to lean more, squeezing out a bit more economy.
- Air temp affects relative fuel mixture, meaning warmer days may require the mixture to be pulled out a bit more. This also is affected when using carb heat, as the mixture will become richer with the hotter air. You may have to lean the mixture to restore best mixture power and / or economy
- More combustion contaminants blow by cylinder rings and end up in oil, making it turn black quicker especially with worn cylinders
- Brakes should hold better at static full power, but as in real life, will still be difficult to hold in position

- Airspeed indicator AoA errors added which means airspeed will indicate lower speeds when very slow
- Made the initial battery draw cumulative and not a minimum value (was masking some single state electric items)
- Re-coded battery code, which increases battery life but lowers charge rates
- Fuel injected primer more sensitive to cold (will need more primer for very cold starts)
- Engine sounds reverberate off terrain (should notice sound drops off appropriately as you lift off)
- New propeller physics increases propeller load with lateral speeds (slips)


Warbirds:
- Re-coded fouling in an effort to help some who are experiencing difficult engine starts


09/26/2014 - 09/28/2014 CHANGES

- Bug where if the plane was left for more than 72 hours, cylinder conditions could be altered


Warbirds:
- Reduced creep on ground checks
- Primer lasts longer
- New cylinder firing and plug fouling logic. Engine won't stall after landing unless you pull the throttle full back and allow the plugs to "load up." After starting, you may notice it takes a 1/2 minute for the engine to run smoothly. This is expected and normal behavior.

- Engine wear
- Cold weather starts
- Rare, unexpected failures
- Failing engines can be nursed to run longer
- Malfunctions can cause engines to sputter, cough, and vibrate gauges
- Improved carb icing / shared carb heat
- Applying high power with high carb air temps (CAT) can now cause detonation

Piper J3 Cub
(v.1.1 released 10/02/2009)

New Features in v.1.1
- Paddle to and from a dock or any shoreline with a functional oar.
- Make advanced water to land landings with Tundra tires. This allows for safer landings near shorelines and lakes. While the tundras are larger than regular tires, they are not floats, so if you get too slow over the water, they can pull you in and nose over. Be careful and respectful of the dangers of skipping over water. The wave physics are enabled, so you may get some bucking up and down at speed.
- Hand towing (CONTROLS PANEL). This allows you to slowly pull or push your aircraft after the engine has been shut off.
- New tie-down physics will hold aircraft steady. If you use the tie down on water, it will simulate a tie down near a dock. The plane will still rock back and forth in the watter, but it will behave as if it is roped down.
- Audible damage physics. This means if you push an engine, especially if cold, you will hear some slightly different sounds coming from the engine.

PASSENGER ON BOARD:
- Nervous Heidi won't comment so much when down low.
- Misc improvements and fixes to Heidi's intelligence.

MISC:
- Wing departure characteristics slightly tuned.
- DAT files automatically get re-located to MY DOCUMENTS / A2A / FSX / J3CUB.
- Tuned (reduced) ground effect.

BUG FIXES:
- Engine damage bug fixed
- Fixed a bug when sometimes hand starting was not possible based on previous flights.
- Sudden damage is relatively less likely when TBO time 1800 is chosen.
- Fixed bug where air starting required the prop movement speed to be slowed down to start.
- Gauge physics improvements and fixes.

- P-40 “Warhawk”
- P-51 “Military” Mustang
- P-51 “Civilian” Mustang


PRIMARY FEATURES

Air vortex physics modeling
Light vortexes are modeled and become increasingly pronounced as your speed slows down. The user should experience a more fluid-likecontrol response especially noticed during slow flight, on final, and in the landing flare.

Thrust immediately affects pitch
We modeled this after our flight tests exposed an immediate change in pitch with power, along with differences between the low wing Cherokee and high wing Cessna. The high winged Cessna 172 is more sensitive to power changes due to its geometry and vertical CoG.

pFactor and torque modeling system tuning complete
Introduced shortly after the C172 was released, we've completed tuning this system with version 2.0. You may notice a little more right rudder will be required.

Wheel pants have an effect on fuselage rumble and wind
Another feature that comes care of A2A's internal flight test program using the latest techniques and monitoring equipment.

Fuel flooding
Over priming can cause the fuel system to flood, requiring certain techniques to clear the system. Fuel flooding happens with there is too much fuel in the intake system and cylinders, making the fuel to air ratio too high for combustion. Just like any other combustion engine, the operator can either wait a few minutes (sometimes more) for the fuel to evaporate or crank the engine over with the throttle 1/2 fully opened to push the fuel through the system. NOTE: On real aircraft, reverse hand propping can also expedite this process but this is rarely necessary.

Engine harmonics and vibrations
We thank our latest A2A sponsor, Lord Corporation (makers of engine mounts), for their assistance in helping us further understand the science of vibration analysis. The user should notice additional cabin vibrations (shudders) when the engine rotation passes through a slow harmonic during start up and shutdown. We've also added the tire-touch torque on the landing gear.

Advanced engine gas temperature (EGT) modeling
This comes from a newly developed testing process developed for the Accu-Sim Cherokee for the most authentic engine leaning experience available anywhere.

Direct Taxi
The aircraft will taxi more precisely and center quicker (rather than continuing too far into the turn), for a more natural taxi experience

Prior C172 Trainer Individual Updates (up to v.1.03) Included
Below is a changelog of the prior C172 Trainer updates included in this installer:

Fixes / Improvements
- Random missing VC Clickspot fix
- Adjusted rudder and toe brake coordination behavior. Flight tested against Cessna 172R N3535H.

New Features
- Simulated Elevator Force Slider
During development and through the heavy flight testing of the Cessna 172R, we started to identify differences between the actual yoke movements in the aircraft and how flight simmers interpret their own controller movements. Now with the masses weighing in, we've narrowed this down to two distinctly different camps defined as "Pressure flyers" and "Deflection flyers." Pressure flyers respond to stick spring pressure, while deflection flyers respond to stick deflection and this interpretation happens somewhere between the hand and the brain. My own personal experience on this is, I used to be a pressure flyer, but with the steady activity flying different aircraft types I've slowly become a deflection flyer. However, we've seen even active pilots that fly flight simulation, fall into either of these camps and anywhere in between. Here at A2A, we've always said "we believe in options." We always want the customer to be king in determining what is right for them and this is largely what this update has been about - our responding to customer needs and wishes. We think / hope we created a bridge for both camps and everyone in between, below.

There is a new slider in the lower left corner of the CONTROLS menu (SHIFT-3) called the "Simulated elevator force" slider (will be labelled later) which the user can adjust the elevator sensitivity based on the simulated forces on the yoke. A value of 0 is the current setup for deflection flyers, and pressure flyers can move the scalar up to fit their needs. This would give full elevator authority at slower speeds, yet allow those who find it too sensitive on their controllers to adjust to their personal preferences.


- New Accu-Sim Torque and P-factor Physics
We removed all FSX torque and p-factor and replaced it with new physics in Accu-Sim. This is an all-new system and is still in progress, but so far what we see is a significant improvement over what we've seen in FSX.


- Created elevator ground effect and additional physics
Accu-Sim models the forces of air over the elevator, allowing for fine control during landing flare and soft field operations. Try pulling the elevator back prior to your takeoff run and feel how the nose comes up earlier in your takeoff run.


- Brake axis and taxiing
Some have reported being "stuck" on the ground while taxiing on different surfaces. Our research and testing has determined that there isn't a single source to this, but several. One has been some controllers not fully releasing the brakes. Another is how FSX manages differential braking. We took Cessna 172R "35 Hotel" up twice since in recent days to dig deeper into this area, installing three cameras with one fixed on the rudder pedals. We then adjusted how the controllers interpret FSX and tuned accordingly.




Additional detailed change log

Controllers
- Blocked mouse wheel on the radiostack and gps units
- Keyboard controls for ailerons, elevator, rudder
- Handling FSUIPC controls for flaps, starter, mixture and fuel selector
- Axis control for flaps


Avionics
- The avionics electric power bool depends on the avionics bus voltage also. No power under 12V
- Switched GNS530 to the first COM
- Changed RXP avionics suite. Com2 instead of Com1, removed Com1 added DME to GNS 430 option
- Autopilot uses altimeter #2
- Autopilot REV mode fixed
- Tuned vertical autopilot to reduce occasional oscillations
- Fixed audio selector panel
- Darker default GPS screens


Misc
- Reduced the lateral weight of the passengers
- Massive plugs a little more resistant to fouling
- Few minor fixes on the textures
- Hypoxia moved 2k feet up (14.5k)
- Damaged vacuum pump now triggers "check engine"
- Slight CoG adjustments and Landing gear strut behavior changes (special thanks to Alex Metzger)
- More cockpit items and configurations saved with aircraft
- Fixed prop hub in VC view
- Reducing MP server flooding
- Fix to right door for SP2 users
- Fixed tooltip of left doors handle
- New landing lights beam logic
- Fixed altimeter pressure scale in hPa
- Faster Accu-Sim to FSX interface
- Maintenance hangar will give more detailed reports if fouled plugs are found
- pFactor and engine torque effect on airframe physics tuned (still in development)
- Smoother drag rumble with flaps (the sound represents a rumble felt in the seat)
- Ground thump volume reduced (taxiing over cracks and seams in the real C172 make very loud, audible thumps due to the main landing gear design. This is maintained and true in the simulator)
- Removed entry in panel.cfg that may have been contributing to missing VC clickspots and some loss of performance on some machines
- Thicker ADF needle
- Fixed text placement on the dash
- New light illumination dll for WinXP users
- Improved autopilot altitude control in low fps situations
- Reduced the number of axis events sent to the simulator
- We hope this fixes the elusive missing vc clickspots some are reporting.
- Increased modeling of pfactor. Should require moderate rudder on roll out, slight taps on takeoff run, slight pressure on a standard climb, increased pressure approaching a stall. Also reverse torque has been simulated. Try flying at a moderate speed, under 80kts ias, and cut the throttle. You should get a very slight roll to the right. The aircraft will always have a slight roll one way based on these power changes (watch how the ball moves). The only time the plane will fly neutral is during cruise operations (when the prop is neither pulling or pushing). The pfactor does pull more than it should while taxiing. This will be remedied in the next update.
- Specific testing and tuning of side forces in preparation for new bank indicator physics currently in development
- Fixed typo on the dash and RPM hour digits lightmap
- Slightly stronger thrust from the stalled prop
- Lowered the speed in which the drag sound from the flaps creeps in to match felt rumble in the C172R
- Fixed a bug that was causing issues from an abnormal AoA value happening when taxiing
- Should fix sticking toe brakes on all systems 100%
