LJ45 Professional

Compatibility: MSFS 2024, MSFS 2020
Just Flight is proud to present the LJ45 Professional – a long awaited incarnation of a classic Microsoft Flight Simulator aircraft is now in development from the Just Flight in-house team.

Previously seen as a default aircraft in the Microsoft Flight Simulator series from FS98 through to FSX, the LJ45 combines a modern, glass cockpit flight deck with high performance flight characteristics, making it a firm favourite within the flight simulation community.

Using the latest modelling techniques, paired with the high fidelity systems of our Professional range, the Just Flight LJ45 Professional will take this well-loved private jet to a level not yet seen in any flight simulator.

LJ45 Professional will include both the LJ45 and LJ45XR variants, with a variety of configuration options, a detailed passenger cabin with galley and toilet, and even a VIP carpet for private jet operations!

See the Detailed Description below for the aircraft features!

Model

  • Accurately modelled LJ45 and LJ45XR variants, built using extensive research materials and hands-on experience with the real aircraft
  • 8K textures are used to produce the highest possible texture clarity, with decals used for high-resolution text

  • Dynamic wing, T-tail and engine flex animations
  • Full support for MSFS visual icing effects and ground services support
  • Detailed passenger cabin, with toilet and galley
  • Ground equipment, including GPU, cones, chocks, flags, engine intake covers and VIP carpet

Cockpit

  • Captain and Co-pilot positions modelled with all switches, knobs and levers animated and functional
  • A truly 3D cockpit environment right down to accurately modelled circuit breakers and screw heads - every instrument is constructed fully in 3D with smooth animations
  • Authentic gauges and navigational equipment, including Primus 1000 EFIS avionics system and UNS FMS
  • Realistic autoflight system including lateral and vertical navigation modes
  • Cockpit textures feature wear and tear based on reference photos taken in the real aircraft to produce an authentic environment
  • Aircraft state system which will automatically save the aircraft state whenever a flight is saved and reload it whenever that flight is loaded
  • Aircraft configuration system which allows you to choose between 'Cold & Dark', ‘Turnaround’ or 'Ready for Take-off'
  • Tablet EFB for controlling various aircraft states, options and payloads, with Navigraph and SimBrief integration and a moving map
  • Developed using the latest MSFS standards, including intuitive and easy-to-use controls for rotary knobs, multi-position switches and levers
  • Fully compatible with MSFS VR mode
  • Custom-coded systems, including hydraulic, electrical, fuel and pressurization

Liveries

The LJ45 will be supplied with a range of liveries from around the world, reflecting its wide and varied corporate service.

  • Support for numerous control assignments for compatibility with controllers and hardware

Development Updates

09 July 2025

Following our recent F70 Professional, F100 Professional and A300B4 Professional in-development updates last week - F70/100 Update here and A300B4 Professional update here, this week we turn our focus to the LJ45 Professional.

Like the aforementioned products, the LJ45 Professional was showcased at our booth at FS Expo, where attendees got a first glimpse of the artwork. We hope everyone who attended enjoyed what they saw, and we look forward to presenting a much more advanced build next year!

From a development perspective, work continues to be focused on the modelling and texturing of both the interior and exterior. These screenshots show an almost complete cockpit model, marking a significant step forward since our last update. The cockpit features high quality textures, accurately modelled controls, screws and rivets (our artist even found manufacturers drawings of these for maximum accuracy!), and the iconic curved CRT displays. All this work takes full advantage of the latest MSFS modelling and texturing techniques, to ensure the highest visual quality with a minimal performance cost.

Unlike the classic aircraft we are used to developing, which often have significant levels of weathering, we have chosen to keep this one more modern and clean, reflecting the aircraft’s use as a well-maintained private jet. However, there is still plenty of subtle wear-and-tear around the cockpit, accurately placed based on the condition of our reference aircraft, with more still to be added.

We always believe that it is reflected in the artwork quality when an artist has passion and excitement for a project, and we hope you can tell from these screenshots that it is definitely the case for our LJ45 Professional!

The typical development cycle of our flight simulation products sees the modelling and texturing work occur first, allowing coding to then begin with a usable model. That is what you can see in evidence here, with our artist paving the way for systems coding to begin soon. Once the essential artwork is complete, our artist will then be free to move onto the next project, whatever that may be (stay tuned!), until we near the testing phase.

For now, it’s all hands on deck (or should we say, cockpit?) for the LJ45 Professional. We’ll share more updates soon as the artwork progresses, and systems coding begins.


08 January 2025

Following it’s big reveal at the end of our 2024 development round-up, we’re excited to launch the In Development page for the LJ45 Professional. A brand new product being developed by our in-house team, the LJ45 will be coming to MSFS 2020/2024 after our F70/100 and A300B4.

Alongside the product description, outlining some of the key features, we have included screenshots showing some of the recent progress on the cockpit and exterior artwork, with the latter already in the simulator. As usual, we will bring you regular updates on every area of the project.

LJ45 Professional is our first business jet product, continuing our tradition of developing a wide range of different and iconic types, and we’re looking forward to bringing our passion and attention to detail to the business jet genre. In addition to wanting to bring back a longstanding default aircraft missing since MSFS 2020, we settled on the LJ45 due to its versatility, long service all around the world, and perfect balance between the old and new.
