Following the wonderful reception of the TorqueSim/RealSimGear Take Command! SR22 Series, we have been hard at work developing the Take Command! SR20 to complement it! This is not a simple modification: it is a product of thousands of hours of work, creating the highest quality rendition of the aircraft for X-Plane.
The X-Aviation Take Command! brand of products represents the very best of flight simulation immersion, and assures you this TorqueSim product is one of the most sophisticated, study sim level aircraft available for X-Plane! Real world pilots test and assist in the development of these products, and real world procedures are followed. It tells you these products are unlike any other product you’ve seen outside of the ever growing X-Aviation catalog! Want to feel like a real captain? Take Command!
While on the surface, the SR20 seems quite similar to the SR22, there is much more changed than what immediately meets the eye. We have worked to develop a fully custom engine model to implement the Continental IO-360-ES engine, with all its proper behaviors and quirks. With the systems, we had to go in and make the systems match a proper G3. The 3D model throughout is significantly revamped to match. This aircraft will be the perfect addition to any simmer’s hangar!
The Take Command! SR20 is designed to work perfectly with the RealSimGear G1000 and Cirrus Perspective Hardware. Learn more about the hardware options here!
The aircraft will be sold separately from the SR22 Series. A discounted upgrade price will be available to those who already own the SR22 Series by release day. As with the SR22 Series, this is for personal use only, contact us for information on commercial pricing. The SR20 will be available in just a few short weeks! For more updates and to be the first to hear about the release date, sign up for our email list!.
Since the release of the Take Command! SR22 Series, we have been hard at work adding features, fixing bugs, and making general improvements throughout! We are preparing to enter a Public Beta in the coming days (if you are interested in being a part of the Public Beta, you can sign up for a spot here – Note: spots are limited), followed by a general release to everyone once it is ready!
Here are some of the key features we have implemented:
G1000 Terrain Profile Indicator
We have integrated a custom terrain profile indicator on the MFD. This will help for situational awareness, especially in mountainous terrain, and help prevent CFIT incidents. The custom system is entirely multi-threaded to prevent any performance penalty.
Visual Icing Effects
We have been hard at work adding custom visual icing effects to the aircraft! This will help with situational awareness surrounding the use of TKS during icing conditions, as the simulated ice can now be seen on the wing, inlets, windshield, spinner, and other relevant surfaces!
Engine and System Model Improvements
There have been many improvements made to the engine model and system model. Here are a few highlighted findings from our debugging and fixing:
SR22TN Power Fluctuations
There was an issue leading to potentially severe fluctuations of engine power during takeoff and climb at high ambient temperatures and altitudes, on the SR22TN only. The cause of this issue has been eliminated. However, there may still be minor residual fluctuations on takeoff and initial climb under such conditions, largely attributed to mixture being slightly too rich for such higher density altitude takeoffs. It can be further amplified by too quick movements of the power lever. To get rid of any remaining fluctuations altogether, embrace the following steps when setting takeoff power at high temperatures and/or density altitudes:
Advance power slowly until the point where RPM rises above 2500 RPM (around 80% lever travel) and wait for manifold pressure to stabilize. This will take a few moments at altitude and is particularly important up there.
Start your takeoff roll and simultaneously advance power slowly to maximum.
Procedures allow you to lean the mixture to 34GPH for takeoff on hot days. It is suggested to follow this step at OATs in excess of 30-35°C to eliminate any residual power fluctuations.
Advance the mixture to full rich after obstacles are cleared. Also keep in mind that it is normal for the turbo-normalized engine to slightly fluctuate for a few moments after power changes before all parameters stabilize. Thus it is generally recommended to make power changes slowly on such engines, so even during go-arounds better take 2-3 seconds to advance to full power.
Random engine cutout during taxi
There was an issue leading to seemingly random engine quits during taxi. A fix is in place that has proven to work in internal tests.
The fuel-injected IO-550 engine can be challenging to start at times, so video tutorials to prepare you for all kinds of cold, hot and flooded starts you may face. We have also seen the most typical cause relates to mispositioning the power lever for engine starting (some even at maximum), keep in mind to set the lever to about 1/4” (i.e. at or slightly above the letter R in POWER). We have determined that there is no issue with the custom engine model.
Engine cutout after landing
When landing at higher density altitudes with the power lever at idle on rollout, it is to be expected that the engine may not be able to hold its idle RPM due to an excessively rich mixture. Lean the mixture to the appropriate X-T letters in MIXTURE immediately after landing and try to keep the power slightly higher than low idle to prevent the engine from quitting in such situations. We have determined that there is no issue with the custom engine model.
This will serve as a formal announcement that we have released the version 1.0.1 update for the SR22 Series. All customers who have purchased the SR22 Series up till now have been sent an e-mail by X-Aviation with complete instructions on how to obtain your update. We have made this a very simple process!

TorqueSim, X-Aviation, and RealSimGear are excited to announce the Take Command! SR22 Series has arrived and is ready to join your hangar! Don’t be fooled by imitations. THIS is the SR22 flight schools will be using! The Take Command!: SR22 Series includes both Normally Aspirated and Turbo SR22 G3 variants in one package. The systems simulation along with 3D modeling is incredible. There’s no other SR22 on the sim market like it.
Fully Custom IO-550 Engine Simulation. Cylinder detonation, spark plug fouling, improper magneto grounding, and more. SR22TN adds the Tornado Alley Turbonormalizing system. All components are modeled from real data with complex inter-component interaction.
Detailed electrical system. Simulation of all buses, circuit breakers, Master Control Unit, both Alternators, and both lead-acid batteries. Inter-system interaction is simulated so loads on the electrical system can affect engine performance.
High-Fidelity Flight Model designed for unparalleled accuracy. Custom airfoils, stall strips, cuffed wings, and accurate control surface deflections are all modeled.
Maintenance and Failure Model. Excessive wear will affect airframe performance and safety, addressed through a realistic concept of runtime-based and annual inspections. This also includes truly unique features like cylinder detonation driven by the physics engine. TKS fluid panels drain over time in warm conditions and need to be primed, tires flatten, brakes fade when hot, the propeller experiences FOD on unprepared surfaces and much more to discover. Probability distributions tuned with real-world data are used to reflect the increasing likelihood of failures with component runtime.
Custom TKS Ice Protection System (FIKI), with full system logic control in all normal and backup modes. Fluid metering pump model down to pump speeds and pressures, correct timing of pump operation cycles, pump speeds and flows depend on system voltage. Clogged filters provokes higher pump pressure and lower fluid flow.
Custom Fuel System with Vapor Lock simulation. Main and Collector Tank are modeled, fuel sloshes depending on sideslip angle, affecting float-sensed quantity and strainer coverage. Every component in the fuel delivery path is simulated and contributes to the overall system behavior. Hot fuel can cause vapor formation and power fluctuations at high altitude in flight, suppressed by use of the boost pump
Oxygen system where flow rate and oxygenation are controlled via a custom oxygen flowmeter. Oxygen tank temperature causes difference between sensed and actual pressure, oxygen flow rate depends on number of passengers on board.
Persistent State – when you shut down the aircraft, you will return to it in the state in which it was left, the engine components will take their real time to cool. This encourages the proper care and handling of the aircraft, and shows the consequences of reckless flying.
X-Plane 11 G1000 avionics with additional customizations including engine pages, synthetic vision, lean-assist functionality, CAS simulation, and checklists. All these customizations are designed to also work perfectly with the RealSimGear G1000 and Perspective Package.
Integrated Synthetic Vision into the PFD with obstacle display, navigation pathways, and airport labels.
Meticulously detailed 3D model, with full 4K PBR textures and the wide variety of materials accurately replicated.
The FMOD sound pack has been the result of hundreds of hours of source audio, carefully recorded from the real aircraft. Recordings of the engine on the ground, and in-flight have provided for a highly-accurate and immersive sound pack replicating the real aircraft. Every switch, knob, lever, and button have been modeled.
The tail number can be dynamically changed on the aircraft! There are many configuration options to make the plane yours – from changing the tail number color, placement, outlines, drop shadows, including adding it to the wings as well!
Heavily multi-threaded systems architecture to leverage performance of modern CPUs with many cores.
Full aircraft state persistence. Every switch, flight control position, fuel state and on-airport position is restored upon reload. Even between reloads, system resources change in real time. The engine and oil cools down slowly between flights, the battery drains, tires slowly deflate, etc.
TorqueSim, RealSimGear, and X-Aviation are excited to announce the SR22 Series for X-Plane will release next week! The SR22 series is the cumulation of thousands of hours of work, creating the highest quality rendition of a piston aircraft for X-Plane to date: everything is simulated! Both the SR22 G3 and SR22TN G3 are included.

3D Model and Sounds
The TorqueSim SR22 and SR22TN have been meticulously detailed to provide for the most in-depth visual model for the SR22 possible. The aircraft makes full use of 4K PBR textures, ensuring the highest level of visual fidelity. All the different materials are accurately represented from samples from the actual aircraft!
The FMOD sound pack has been the result of hundreds of hours of source audio, carefully recorded from the real aircraft. Recordings of the engine on the ground, and in-flight have provided for a highly-accurate and immersive sound pack replicating the real aircraft. Every switch, knob, lever, and button have been modeled in the sound-pack.
Both the SR22 G3 and SR22TN G3 are simulated. The SR22 is equipped with a normally aspirated Continental IO-550-N capable of 310 HP, while the SR22TN models the Tornado Alley turbo normalizing system attached to the engine. The TorqueSim custom physics model is the most accurate simulation of a piston engine for X-Plane! The simulation models the mass flows of air and fuel through every part of the engine in real time. Air enters the engine through the air filter, flows through ducts, passes obstacles like the throttle plate, burns the fuel and leaves the engine as exhaust gas. Pressures and temperatures are calculated in every section independently, all contributing to the different segments of the simulation. With the Tornado Alley turbo-normalizing system installed, the full performance capability of the engine model comes into play, as compressors, intercoolers, wastegate and turbines also have their places in the calculation of air flows and pressures. All engine parameters are tuned against a huge database of real engine log data to ensure maximum possible accuracy in all phases of flight. The entire engine simulation runs on a separate thread from the main simulator. This allows for the timing necessary for proper simulation, independent of sim frame-rate, but also ensures that the model has a near-zero performance impact on the simulator!
Significant work has gone into enhancing the Laminar G1000 to provide many of the functionalities in the G1000 Perspective suite. Synthetic Vision, as implemented in HotStart’s TBM900 and TorqueSim’s Pocket Rocket has been integrated. The engine pages and sidebar have been modeled fully to provide the necessary details for proper engine management. Lean-assist functionality has been integrating assisting in the proper leaning of the engine. Checklists have also been integrated onto the G1000 providing easy access to the necessary preflight, starting, in-flight, post-flight, and emergency procedures. In addition to these additions, numerous other tweaks were implemented including matching the Perspective’s Top-Bar details including % Power, and destination calculations, in addition to the integration of “Know your Limits” and the fuel calculator system (which we implemented as a custom interface for refueling the aircraft!). All these customizations are designed to also work perfectly with the RealSimGear G1000 and Perspective Package.
The SR22 electrical system has also been intricately detailed, ensuring every last breaker and switch is modeled. The dual-batteries are simulated with a custom lead-acid battery simulation. The dual-alternator setup and Master Control Unit have been intricately tuned to interface with the rest of the simulation. All 11 electrical busses and 48 circuit breakers are individually simulated to provide for the most in-depth of simulation.
Fuel, Oxygen, and TKS Systems
The SR22 fuel, oxygen, and TKS systems have all been custom simulated, providing for unparalleled accuracy in-flight. The fuel system models all the details down to the fuel lines and injector nozzles! Fuel temperature is calculated and vapor is formed in the lines under the right environmental circumstances. This also allows for the recreation of all engine starting characteristics usually found on an aviation piston engine like normal, cold, hot, flooded and false starts. So be sure to understand the importance of your boost pump both on ground and in flight! The complex behavior of the engine driven and electric fuel pumps as well as the fuel manifold and metering unit are simulated. Changing bank and attitude of the aircraft affect sloshing in the tank, thus causing the indicated fuel quantity to differ. The TKS system models the multiple operational modes through the independent simulation of tanks, pumps, and fluid lines. The oxygen system is no slouch either – the tank, along with a configurable flowmeter are integrated to provide for an excellent platform for high-altitude operations. The simulator‘s hypoxia simulation is modulated to reflect real time of useful consciousness depending on oxygen flow, so make sure to configure the flowmeter properly!
Maintenance and Failure Model
The SR22 also features an engaging and beneficial maintenance, wear, and failure model. This aspect of the simulation makes sure that the plane is flown safely and without damage. Excessive wear will be affecting airframe performance and safety, addressed through a realistic concept of runtime-based and annual inspections. The entire wear and failures logic is built on top of the physics model for engine, airframe, fuel, TKS and oxygen systems. This also includes truly unique features like cylinder detonation driven by the physics engine. TKS fluid panels drain over time in warm conditions and need to be primed, tires flatten, brakes fade when hot, the propeller experiences FOD on unprepared surfaces and much more to discover. Probability distributions tuned with real-world data are used to reflect the increasing likelihood of failures with component runtime.
High-Fidelity Flight Model
The flight model is designed with unparalleled accuracy. The tuning of the aerodynamic profile required hundreds of hours of careful tuning to accurately match the real-world characteristics. The base model was created by X-Aerodynamics, and further built upon to match the aerodynamic quirks of the real aircraft to the limit of the simulator!
Persistent and Performance Tuned
The countless systems are all designed with persistence in mind – when you shut down the aircraft, you will return to it in the state in which it was left, the engine components will take their real times to cool. This encourages the proper care and handling of the aircraft, and shows the consequences of reckless flying. These systems are also designed to run on computers of many different specs. All the systems are programmed in C/C++ using the X-Plane SDK. No compromises were made for simplicity. The plugins make significant use of multithreading to have the absolute minimum processes running on the main simulator thread, thus helping keep X-Plane performance at its maximum!
