The Accu-Sim P-51 Mustang is here finally in its P3D v4/v5 guise. Back in 2004 we released a P-51D for Microsoft Flight Simulator 9 that used a flight modelling process known as 'Absolute Realism'. A lot of characteristics were being experienced for the first time in flight simulation. If you flew flight simulators, you were used to the old 'yank and bank' as most flight simmers held the position that aircraft really didn’t spin. This was largely because, back then, developers were largely programmers with no flying experience. Even today, while it’s getting more common, it’s still rare to find a developer who actually has even taken the controls of a real aircraft. Today, A2A has the wind at our back, with Accu-Sim helping to bring serious aviators and simulation together. However, the industry as a whole hasn’t really budged that much as people are discovering that it’s not enough to be a pilot, or even a highly experienced pilot. It takes an entirely different skill set to be able to observe, translate, and re-create the experience. It’s not being a pilot, aeronautical engineer, or even a highly skilled aircraft modeller that makes the difference. It's the combination of 'all the above' with, perhaps most importantly, a relentless drive to re-create the most believable experience possible. Even if you have never flown an aircraft before, you are a living person with an inherently deep sense of what is right or wrong in the physical world you live in. You touch things, see things, and hear things every minute of every day. So trust your instincts, because, if it doesn’t feel or sound right to you, it probably isn’t right.
Also, in the real world, actions create lasting results, both good and bad. There are consequences everywhere inside of a cockpit, especially a high-performance, propeller-powered, combustion-driven aircraft. This is where the persistent aircraft makes all the difference. In the real world, you don’t get a fresh new aircraft every time you strap yourself into the cockpit. The aircraft is a physical machine that exists in the world. If your aircraft was pulling to the right when you parked it, it will still be pulling when you taxi to the runway the next day. When things happen in a simulated world as you expect in the real world, you start to treat it as if it is just that - real. With lasting results, wrapped inside the newest modelling and advanced material-making techniques, you will have an aircraft that you can spend not just minutes, but hours admiring.. Together, with professionally recorded sounds and physics, the end result is the sense of having a complete, real, majestic, raw, flying machine stuffed inside your computer. And we hope, you don’t just treat it like any aircraft, but rather like 'your' aircraft. We hope you enjoy your new beautiful bird, and hope you learn to fly and treat her well.

Auto-mixture that actually performs as intended. Now you can set for 'RUN' and the aircraft fuel-to-air ratio will be automatically determined and set by the carburettor based upon various factors such as altitude.
-
Dual speed, dual stage supercharger modelled with accurate behaviour

-
Feel the exhilaration of flying an Accu-Sim-powered P-51 Mustang
-
Mach drag built and tested specifically for the P-51D airframe
-
Merlin V-12 liquid cooled V-1650 engine built to manufacturer’s specifications
-
A true propeller simulation
-
Electric starter with accurate cranking power
-
Dynamic ground physics including both hard pavement and soft grass modelling
-
Primer-only starts are now possible. Accu-Sim monitors the amount of fuel injected and its effectiveness to start and run the engine.
-
Cold mornings require energising the primer for 3-4 seconds, and warm starts may only need a second or two.
-
Immersive in-cockpit, physics-driven sound environment from A2A engineered P-51 recordings
-
Complete maintenance hangar including landing gear, internal systems and detailed engine tests including compression checks
-
Understand how a high-performance aircraft behaves and see how well you can cope with all of the unexpected things that can happen. No two flights are ever the same!
-
Piston combustion engine modelling. Air comes in, it mixes with fuel and ignites, parts move, heat up, and all work in harmony to produce the wonderful sound of a V-12, liquid-cooled racing engine. Now the gauges look beneath the skin of your aircraft and show you what Accu-Sim is all about.
-
Airflow, density and its temperature not only affect the way your aircraft flies, but how the internal systems operate
-
Real-world conditions affect system conditions, including engine temperatures. Manage temperatures with a radiator flap and proper flying techniques.
-
Spark plugs can clog and eventually foul if the engine is allowed to idle too low for too long. Throttling up an engine with oil-soaked spark plugs can help clear them out.
-
Overheating can cause scoring of cylinder head walls which could ultimately lead to failure if warnings are ignored and overly abused
-
Large-engined aircraft like the P-51 like to be in the air, not on the ground. So don't idle for too long, get in the air where the air supply is plentiful.
-
Engine, airframe, cockpit panel and individual gauges tremble from the power of a high-performance combustion engine
-
Authentic component drag. Dropping your gear will pull your aircraft realistically as the landing gear is deployed along with cooling flaps, ordnance and even opening the canopy. Drop your gear, deploy your flaps, or just try a dive, and listen to your airframe.
-
System failures, including flaps that can independently jam or break based on the actual forces put upon them. If you deploy your flaps at too high a speed, you could find yourself in a very dangerous situation.
-
Total audible cockpit made with recordings from the actual aircraft. Before you fly, enjoy clicking everything.
-
Primer system modelled. Accu-Sim monitors the amount of fuel injected and its effectiveness to start the engine. Cold mornings require as many as 12 strokes and warm starts may only need a single shot.
-
Authentic battery. The battery capacity is based on temperature. The major draw comes from engine starting.
-
Oil pressure system is affected by oil viscosity (oil thickness). Oil viscosity is affected by oil temp and oil dilution level. Now when you start the engine, you need to be careful and not raise RPM too much until oil temp is high enough to give proper oil pressure. If you raise RPM too high on a cold engine, especially very cold, oil pressure can raise to over 150 PSI. Oil pump failure can result. Extended inverted flight (negative g) can uncover the oil sump and reduce oil pressure. Do not fly in a negative g situation for more than five seconds.
-
Oxygen starvation (hypoxia) is modelled. Just take off and climb without oxygen to see.
