Accu-sim P-51 Civilian Mustang (FSX)

(7 customer reviews)


The P-51 Mustang represents the very pinnacle of wartime development, and today hundreds of P-51’s fly in a modern world and perform not just adequately, but admirably. The P-51 Mustang today is an outstanding, all weather cross-country platform. It is considerably faster and can fly further than the fast majority of general aviation aircraft, and is just shy of the speed of a personal jet.

The release of the new “Civilian Mustang” marks an important milestone for A2A. Our roots have been in both general aviation and military aviation history, and A2A has used this passion and experience to bring many Warbirds to Microsoft Flight Simulator X. However, this release does our best job combining these two worlds. At the break out of World War II, the skies were filled with aircraft developed in the mid to late 1930’s. Aircraft were still transitioning from fabric to all-metal designs, and for the most part, automatic systems management really did not exist. The height of single-engine complexity would be the P-47 Thunderbolt, which had a plethora of systems to manage (manual cowl, cooling, and oil flaps, manual turbo, manual throttle management, etc.). The pilot was being taxed to just fly the aircraft, let alone engage an enemy or avoid being attacked. Over the course of the war, aircraft were made ever more aerodynamic, engine power was pushed to its limit, and systems were gradually made to work automatically. The P-51 Mustang represents the very pinnacle of this wartime development, and today hundreds of P-51’s fly in a modern world and perform not just adequately, but admirably. The P-51 Mustang today is an outstanding, all weather cross-country platform. It is considerably faster and can fly further than the fast majority of general aviation aircraft, and is just shy of the speed of a personal jet. While maintaining a real Mustang is hobby for the wealthy few, Mustang pilots today regard their aircraft as sturdy and reliable. During the development of the Accu-Sim Mustang over the years, we have taken four test flights in two different Mustangs flying today. The cockpit we designed in this Civilian Mustang was designed over many months with the assistance of Mustang pilots, owners, and our own in-house staff. Owning and operating a Mustang today is a dream to many, and this is what we believe flight simulation is all about. Make your dreams come true.


  • Experience one of the fastest and most powerful propeller driven aircraft in the world today

  • IFR cockpit exclusively designed and built from Mustang owners and A2A in-house pilots

  • As with every A2A aircraft, it is gorgeously constructed, inside and out, down to the last rivet.

  • Designed and built to be flown “By The Book“.

  • Visual Real-Time Load Manager, with the ability to load fuel and stores in real-time.

  • Naturally animated pilot in authentic gear.

  • 3D Lights ‘M’ (built directly into the model) with under-wing landing light than can be turned on, deployed, and retracted and fully functional recognition lights.

  • Pure3D Instrumentation now with natural 3D appearance with exceptional performance.

  • Sound engineered by A2A sound professionals.

  • Oil pressure system models oil viscosity (oil thickness).

  • In cockpit pilot’s map for handy in-flight navigation.

  • 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 carburetor based upon various factors, such as altitude.

  • Dual speed, dual stage Supercharger modeled with accurate behavior.

  • Fuel delivery system simulated.

  • All models include A2A specialized materials with authentic metal.

  • Pilot’s Notes pop-up 2D panel keeps important information easily available.



  • A true dual-speed supercharged engine experience.

  • 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 modeling.

  • Primer-only starts are now possible. Accu-Sim monitors the amount of fuel injected and it’s effectiveness to start and run the engine.

  • Cold mornings require energizing the primer for long 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 modeling. 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 it’s 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 and smoke.

  • 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 modeled. Accu-Sim monitors the amount of fuel injected and it’s 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 5 seconds.

  • Oxygen starvation (hypoxia) is modeled. Just take off and climb without oxygen to see.

    The Civilian Mustang was my first A2A “warbird”. P-51D is a challenging and hard to master aircraft, but also very rewarding! A2A have managed to capture the essence of this WW2 fighter!

  2. djjose (verified owner)

    Outstanding! Love the updated VC. This bird will test your Piloting skills. Very challenging and rewarding military taildragger.

  3. markadeane (verified owner)

    An initially humbling experience, finally getting control of this warbird took patience and effort, but was one of the more rewarding challenges I’ve undertaken in sim.

    The P-51D civilian was my second A2A aircraft and my first A2A warbird. And boy was I in for a treat. The sound alone of that big V12 up front after start up is just amazing. It definetly gave me goosebumps. In the beginning the Mustang is a lot to handle especially on takeoff and landing but it is so rewarding once you get it right. The civilian version gives you the oportunity to just fly some aerobatics or cruise at speeds well above 200kts. In my opinion this is also a total must have if you love aviation and flight simulation.

  5. tune82 (verified owner)

    One of my favourites, really like the way A2A made a civil / “after war” version with modern avionics. Like a real stallion you have to watch her every move, especially on take-off.

  6. Blue1 (verified owner)

    My first A2A bird: just amazing, from the flight model to the last detail, Incredible!

  7. Tomas Linnet (verified owner)

    When I purchased the P-51D Civilian was my first A2A warbird, now it is the most used A2A aircraft and I don’t see why this would ever change. The sound from the Mighty Merlin during is very good, actually I run the sound a bit higher when in the P-51… As always with a A2A aircraft it is beautiful modelled on both the inside and the outside. Because of the modern avionics, I travel the virtual world in my P-51, luckily virtual 100LL is free. Especially with a full fuel load the P-51 is a beast to handle on take off and maneuvering, but as always practise makes perfect.
    Special thanks to Mr. Dudley Henriques for his tips and tricks on the P-51

    5 out of 5 from me.

    Enjoy your flight!
