Note: While version 1.2 remains a classic snapshot of the aircraft's history on X-Plane 11, IXEG has since continued development, releasing massive overhauls (such as V1.5 and beyond) that introduce full compatibility with X-Plane 12, upgraded visuals, and entirely rewritten modern systems.
However, it's also important to acknowledge that as a product that has evolved over many years, the IXEG 737-300 has a few minor limitations. Some community reviews have noted that a few advanced functions, such as holds in the FMS, were not fully implemented in earlier versions. Additionally, its official support platform, X‑Aviation, and its Gizmo DRM plugin have occasionally been a source of minor frustration for some users. That said, the developers have continued to update the aircraft, and the current version has addressed many of these historical points, making it a more polished and complete product than ever before. The v1.2 update was a significant milestone in this ongoing journey of refinement.

The by International X-Plane Engineering Group (IXEG) stands as one of the most iconic, high-fidelity airline add-ons in the history of flight simulation. Developed in partnership with X-Aviation, this aircraft transformed the airliner landscape for Laminar Research’s X-Plane 11 by replicating the distinct, analog-to-digital transitional era of the Boeing 737 "Classic" series.
was a pivotal update for X-Plane 11 users, refining the flight model and fixing critical bugs that allowed for a more seamless "cold and dark" startup experience. Key Features of IXEG 737-300 V1.2 Developed in partnership with X-Aviation
This particular version, v1.2, is for X‑Plane 11. However, the latest version of the IXEG 737 Classic is built for X‑Plane 12 and also works in X‑Plane 11.
