Take Command! – IXEG 737 Classic – 1.33


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

Developer: International X-Plane Engineering Group (IXEG)
Download Size: 1.2GB
Comaptibility: Mac and Windows. No Linux. Now fully X-Plane 11 compatible!

The team behind the IXEG 737 Classic consists of some of the most experienced and skilled developers ever assembled in X-Plane. In total, the team of professional on-type pilots, engineers, programmers, 3D, and texture artists come with a combined X-Plane developer experience of over 50 years. This know-how, combined with access to an overwhelming amount of hard to get technical documentation and passion for the aircraft has resulted in an airliner simulation that will not only set a new benchmark standard for X-Plane, but maybe for the whole desktop simulation community.

The main objective of the IXEG development team has been to build a simulation as realistic as possible and as seen from a real world pilot’s perspective. In other words, the real world 737 Classic pilots on the team (who have been involved in the project from day one) have played a central role in the development of this product. Combined, these pilots have tested the aircraft in X-Plane for some 500-1000 hours (block time) prior to release and many additional hours in development consulting.

Systems & Avionics
Created with the idea no detail would go missed, all systems have been meticulously modeled to bring you the highest possible fidelity. The electrical system, for example, is modeled from every breaker and relay upwards – no scripted behavior (think schematics). The hydraulic model takes flow-rate, quantities and pressure differentials into account. All systems that are present in the real plane have been mimicked with painstaking detail, and way beyond what the average user or even airline pilot will ever explore.

The avionics and entire cockpit have been developed not only with an accurate representation in mind, but the team also paid close attention to the correct appearance of screens, annunciations and warning lights. Screens flicker to life when switched on. Lights also ramp up and wane in a believable fashion. The ultimate goal was and is to make you feel like you’re sitting in the airplane that has been the workhorse of many major airlines over the past decades – not some sterile airplane straight out of the assembly hangar.

Huge efforts have been put into the flight and engine model of this aircraft, which was one of the first things that we started working on in the year 2010. The results are both impressive and amazing! Many are unaware just how important an accurate flight and engine model is to the overall experience of the aircraft, both in automated and manual flight. This aircraft is far beyond the accuracy of any airliner ever made in X-Plane to date! This, combined with the superior flight dynamics of X-Plane and incredible avionics, will give you an experience never had before in any desktop simulation. It truly is remarkable.

Having the right lift, drag and thrust in the entire envelope of flight is critical, even in automated flight. Without this being accurately modeled your vertical flight path would be inaccurate and VNAV/FMS operations and calculations way off. Also, autopilot performance is strongly negatively influenced by having a poor flight model (unlike the IXEG 737 Classic). In manual flight the combination of feel, aerodynamics and avionics are even more important, of course, especially if you want to fly manual approaches, CAT 1 landings in poor visibility, strong winds etc. With this simulation it is no longer a problem!

Version 1.33? Would be nice to know.


Sorry, no, this is the 1.20 version with overwritten models and files from 1.33

Last edited 4 months ago by SimWareHouse

Relatively new to using XP since I’m coming from MSFS, transferred all the files over to my XP11, loaded up the aircraft but none of the switches are working, does this require any type of activation? Also want to note upon loading captain and FO model were in the cockpit basically blocking a majority of my view.


I too have the issue of not being activated. Ive run the XAkeygen file and replaced the “License_db” bin file. Possibly an issue with Gizmo?


where i need to put rhe licence files?


Where do you put the license files???


1) Extract all files from the archive to the root folder of X-Plane11
2) From the X-Aviation folder located in the root of the simulator, run “xaLicenseGenerator”
3) If the B733 is not in the selection menu, then the aircraft should appear in the menu.
4) Put a check in front of B733 and click on the LEFT button if Windows, on the right if Mac.
5) Now the license_db.bin file has appeared in the X-Aviation folder, you don’t need to do anything with it.
6) Enjoy your flights and soft landings!


How do you put a check next to it?


But there is NO xaLicenseGenerator.exe !!

Just an XML file named “xaLicenseGenerator.xml” which as I’m sure you know cannot be run.
