Step into Immersion

The Classic Plus Difference.

Introduced in 2016, the Take Command! IXEG 737 revolutionized flight simulation immersion. Now, with the IXEG 737 Classic Plus, experience even richer 3D visuals, enhanced lighting, more authentic sounds, and an improved flight model in X-Plane 12. The classic just took a leap forward.


A sense of reality every time you enter the cockpit.

Take Command!

The X-Aviation Take Command! branding represents the very best of flight simulation immersion, and assures you this 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!

Physics-Driven Systems

The heart of realism starts here.

3D Model

Built on engineering "first principles," the IXEG system simulations closely mimic real-world physics and behaviors, offering an unparalleled realistic experience. For sim pilots, the feedback from these systems simulations are reflected in the instrument and gauge indications you observe to operate the aircraft. See annunciator lights fade out slower than they illuminate. See the flaps deploy slower when using electric pumps vs. engine driven pumps! See lighting fade out slowly as the battery drains. One reason the IXEG is so immersive beyond just the 3D and the sound, is all those indicators: the LEDs, the gauge needle movements, the annunciator light illuminations, are driven by underlying physics models so their behaviors also just seem right. Many IXEG users like to say, "There's just something about the way the IXEG feels". The first-principles system simulations are a large reason why!

Detail Mastery

Crafting Perceptual Realism.


Detail is in the DNA of the IXEG 737! Guided by questions about what makes things authentic, the IXEG team ventured to redefine the boundaries of simulation fidelity. Geometric fidelity, textural fidelity, tonal fidelity, color fidelity, aural fidelity, dynamic fidelity, photometric fidelity, etc. This approach allowed the team to gauge every element of their work: the 3D, texturing, lighting, animations and sound development against a particular fidelity standard and focus on details in those areas that most affect our perception of the physical world! We all want to feel there and the numerous and subtle execution of details in the IXEG take you as close as any flight sim product can! All you have to do is look!

Flight Model

Expert-Designed Flight Dynamics: Feel the Authenticity.


The IXEG flight model is easily one of the best flight models in all of flight simulation. It's hard to describe until you experience it yourself. Crafted by engineer Morten Melhuus and 737-300 captain Jan Vogel (now a 747 captain), the flight model stands as one of the best. Extensive comparisons were done by Jan with the real aircraft performance to ensure that this simulated version feels and flies the same as the real thing. The result speak for itself. Indeed you will find that many many owners enjoy hand-flying approaches and landing in the Classic simply because it feels so natural and is so satisfying!

Aural Brilliance

The Distinctive Roar of Classic Plus

Many IXEG customers remember one thing from their first experience: the unparalleled sound quality. Sound is so fundamental to our experience of reality, that the IXEG team wrote their own spatial sound engine so they could achieve the aural fidelities they knew were critically important to an immersive experience. To this day, there is no other product that comes close to the IXEG for its famous fly-by jet roar! Truly one of kind and all the other sounds are equally as immersive. If you're experiencing the IXEG for the first time, we bet you'll remember the sounds too! Check out the flyby sound!
