Our New Native Gates Learjet 25 Addon for Microsoft Flight Simulator 2020 (compatible with MSFS 2024)
Our new GLJ Model 25 addon is a native MSFS aircraft from top to bottom! 3D models and animations from our previous versions for other platforms needed to be fully revised, modified and optimized for the new simulator. Collision meshes, “occluders”, and new “levels of details” were added to the models to conform to the official recommendations and to improve performance in multiplayer and AI modes. Aircraft systems were rebuilt in accordance with the new simulator’s requirements, and over 30,000 lines of code for the model behaviors had to be rewritten and organized within the new MSFS XML template system. New PBR materials and textures were created, along with new dynamic lights and visual effects.
Our Gates Learjet 25 model has never appeared more impressive than within the visually stunning graphics environment of the new Microsoft Flight Simulator!
Most notably, we also produced a new sound package in Audiokinetic Wwise, a powerful sound authoring software for video games that sets new standards in MSFS. Authoring interactive sounds and implementing an immersive, realistic, and accurate representation of a simulated environment with Wwise for our Learjet Model 25 addon was a complicated task but the impact on the simulation is worth mentioning.
A Fighter in Civilian Clothing
Nicknamed “fighters in civilian clothing” because of their sleek design and amazing performance, the classic Lear Jet/Gates Learjet 20 Series aircraft were the first true private jets and redefined business aviation during the 1960s and 70s, flying high above the weather at transonic speeds. Their capabilities earned them a place among the extreme aircraft, setting record after record. Capable of maneuvers you would never attempt with another civilian aircraft, their performances as general aviation business jets are simply unequaled, according to real-world Learjet 20 Series pilots, even by today’s standards!
With the longer-range Gates Learjet Model 25D, by which this addon is inspired, came a longer cabin, increased seating capacity, more flexible loading options, greater fuel capacity and a sleek-looking stretched fuselage.
A Unique Addon for your Hangar
The Xtreme Prototypes GLJ Model 25 Classic SE for MSFS is a next generation addon designed to take advantage of the new and more powerful gaming computers and graphics hardware that are available today. Nothing was spared in our efforts to faithfully reproduce its retrofitted instrument panels, still in use today, carefully modeling, and animating each “steam gauge” and mechanical device with all the necessary moving parts. Except for the GNS 530 and radar screens, the ADDUs, and the new radio’s VFD displays, which are flat by nature, no legacy 2D gauges are used in our model.
The result is a unique addon that strives to bring you not only the actual feeling of flying a high-performance aircraft now equipped with modern avionics, but also the spirit of maneuvering such a vehicle at times where large LCD screens and powerful computers did not exist, and where pilots needed to know how to fly and navigate with minimal resources and rely on their own experience, abilities, and judgment.
At Xtreme Prototypes, we consider our addons as real micro aircraft simulators rather than just games. Our products require extended periods for development and testing by a passionate team of artists, technicians, and pilots. We pay attention to every detail, and we do our best to make sure that we provide our users with the best flight simulation experience they can get within the limitations of the available simulation platforms.
We believe our GLJ Model 25 addon is the most advanced, detailed, and faithful classic Learjet simulation you can find.
Designed by Users for Users
Becoming one of our users makes you an important member of our development team. This new version of our GLJ Model 25 addon is the product of the many ideas, comments, and suggestions we received from desktop pilots like you from around the world since version 1 of our 20 Series business jet addons for Microsoft Flight Simulator X was launched back in 2009.
We wish to express our gratitude to all our users, followers, reviewers, test pilots (real and desktop), ex-Learjet employees, partners, and friends for their contribution to the making and success of this extreme aircraft simulator.
Thank you for your continuous support!
