What is Accu-sim?
If you throw a baseball, a paper airplane, and a stick into the air, each would behave differently based on it's weight, density, and shape. Each will interact with the air and ultimately the ground very differently, just as we would expect. But what if you dropped a tennis ball on a hard surface, and instead of bouncing, it just hit the ground with a loud 'clunk' and stopped? We are physical beings that live in a world that has certain truths we take for granted, that is until they are gone. However, in a simulated world, nothing can be taken for granted. In fact, if the physics in a simulated world are not specifically created by someone, they simply do not exist. With Accu-Sim, we have built-in to this simulation many of the physical rules that we know to be true and which we expect to exist in the real physical world.
For example, if you start a simple engine that is cold, you expect that it will run rougher and less reliably than when it is warmed up. If one morning you start your cold engine and something seems different, if it does not behave as you expect it to, you will notice this and your senses will tell you, “something is not right.” This is because you have become accustomed and comfortable with how your aircraft responds at all times, not just in the behavior of a single gauge, but in subtle ways -- the way the engine sounds and responds to the throttle, the way the body squeaks, or even in the way the air sounds as it passes by your airframe at different airspeeds. More obviously, if you taxi on the grass, you expect your aircraft to buck and dip as it moves over bumps and depressions in the ground. Similarly, you would also expect to sway and rock if sitting on unsettled water in floats. All of this, and much more, will be experienced and brought to you more accurately and realistically by Accu-Sim. Now it's an entirely new and more real world. It's a world that makes you believe you literally have a physical piece of equipment stuffed inside your computer monitor because all of these little physical truths which cause actions and reactions, and which you notice when they are there or not there, have been created in Accu-Sim. It is all of these little clues which we experience and observe, and which we take for granted in our real world, which make things seem real to us. When they are missing or portrayed inaccurately, things just don't seem right. You know it; you sense it, and so do we.
Perhaps the most important thing this little airplane will bring to you is honest, true-to-life stick-and-rudder flying, something pilots often forget after flying large, heavy, fast, complex aircraft for a while. You will be actively engaged in flying this Cub almost all of the time. After just flying it for a very short while you will start to feel like a better pilot, and you will be.
This little Cub represents the most complete and accurately flying aircraft which we have created to date. With it, A2A proudly delivers to you the “Total Flying Experience”.
The A2A Piper J-3 Cub Accu-Sim Expansion Pack FEATURES:
- Accu-Sim physics creates an entirely new world including true wing, airframe, engine, ground, water, and internal systems behavior.
- Passenger On BoardTM adds a new dimension of piloting realism with an intelligent passenger that is aware of the surroundings, talks when appropriate, including being able to spot and call out traffic.
- Third generation Accu-Sound now allows for a direct connection to the Accu-Sim and FSX physics engine with airflow through the airframe, window, and door, structural creaks, bumps, jolts etc. with three hundred and ninety sounds in all.
- Piston combustion engine modeling. Air comes in, it mixes with fuel and ignites, parts move, heat up, and all work in harmony to produce the most accurate combustion engine simulation available.
- Engine has an actual life. Good piloting skills are rewarded with longer life and more reliable performance.
- New propeller physics means the propeller is constantly active and allows for both hand and air starting the engine.
- Ground physics realistically rock your wings and buck your tail. Regular tires, skis, and large tundra tires all have their own distinctive ground handling benefits and limitations. Each aircraft comes with its own sound set which is tied in with the physics of the airframe.
- Tundra tires demand respect for the size and weight of the larger tires. 3-point landing on tarmac is highly recommended.
- Water physics simulate waves, water drag, and creates an authentic “on the step” experience.
- Total audible cockpit experience made with professional recordings from three actual Piper J-3 aircraft.
- Fuel System allows for an authentic primer system with fuel in lines, tank, and authentic gravity-fed fuel-air mixture.
- Third generation engine wear and oil system including an engine that sputters, spits, and runs rough when damaged.
- Both engine and airframe physically vibrate and shake, based on real world conditions.
- Latest generation carburetor icing modeling, which is critical for the proper management of the Continental A-65-8 engine
