Following the release of MSFS 2024 in November 2024, we (Just Flight) have remained committed to offering free-of-charge compatibility updates for all of our MSFS 2020 products to bring them across to the new simulator. The first of these compatibility updates was released with the RJ Professional v1.2 update.
Just like with the launch of any piece of software, some bugs, limitations or quirks do exist within MSFS 2024 that may affect your simulator experience. We have therefore created this FAQ to cover some of the known issues that we have discovered whilst developing the RJ Professional compatibility update in MSFS 2024.
This list is intended to highlight issues users may find when using our RJ Professional in MSFS 2024 and to provide a means that we can easily communicate them. it is not intended to be a comprehensive bug list or review of the MSFS 2024 simulator, nor is it intended to imply any opinions. We have every confidence that Asobo/Microsoft are listening to and acting upon the feedback raised by the community and that a large amount of these findings will be fixed in the upcoming hotfixes and sim updates.
If you suspect you may have found an issue with the RJ Professional, or its MSFS 2024 compatibility that isn’t covered on this list, please contact Just Flight Support and one of our support team will be able to investigate that further.

1. An issue within MSFS 2024 can prevent aircraft from initialising correctly when compiling WASM gauges for the first time. When loading the RJ on the runway for the first time in MSFS 2024, it will likely immediately shut down the engines and the IRS’s will not be aligned. The most efficient method of ensuring the WASM gauges compile correctly is:
- Install the RJ Professional (MSFS 2024)
- Load a flight in one of the RJ variants on the runway (this very first load will likely cause the aircraft to load in with engines shutdown and IRSs not aligned).
- Return to the MSFS 2024 Main Menu and select a different RJ variant (if you loaded the first flight in the RJ70, load into the second flight with the RJ85 or RJ100).
- Load this second flight on the runway again and the RJ should load in with a "ready for takeoff state).
Alternatively, closing and relaunching MSFS 2024 after the initial RJ load can also fix this issue.
Once the WASM gauge has successfully compiled, all future flights should load without issues, however, this process may be required every time the product is reinstalled/updated (or may not be required at all depending on future MSFS 2024 patches/sim updates, or if our development team finds a more reliable method).
Edit (10/12/24): An issue with the initial release of the Navigraph's AIRAC 2412 navdata also introduced a similar, but different, issue which would cause the ND and GNLU-910A FMS displays to remain blank after loading into the aircraft. This was promptly fixed by Navigraph and users are now able use the AIRAC 2412 navdata supplied via the Navigraph Hub app. We highly recommend that Navigraph users reinstall the latest RJ navdata through the Navigraph Hub app to ensure that this issue does not occur on your future flights in the aircraft.
2. The aircraft will take approx. 5 seconds to initialise once loaded into a flight. This is an intentional addition by our development team and is necessary in MSFS 2024 in order to increase the reliability of the correct aircraft state being initialised. If you are ever in doubt about the state the aircraft has loaded in at, a restart of the simulator will be the safest option.
3. External lighting, such as the beacon and GPU lights, will illuminate the interior of the aircraft. This is an issue which is also affecting the simulator’s default aircraft. We have, however, applied some minor tweaks to the beacon/GPU lights to at least prevent them from flashing inside the cockpit.
4. Due to the eye adaptation within MSFS 2024, there are certain instances where some emissive textures in the cockpit (EFIS displays, annunciators, etc.) can appear overexposed. This is most prominent around sunrise and sunset, which is also around the same time that MSFS 2024 automatically brightens/dims all the emissive textures in the cockpit. This is actioned automatically by the simulator and an abrupt change in cockpit emissive brightness may be noticed when the simulator time changes from Night > Dawn, Dawn > Day, Day > Dusk, or Dusk > Night.
5. Some emissive textures, including cockpit lighting and exterior lighting, may appear to be non-functional during the daytime. The emissive textures themselves are functional and in some cases can be seen working when looking directly at the light sources, however, they may not produce any 'bloom' or 'splashes' like you would expect to find in MSFS 2020, or during nighttime in MSFS 2024. This we believe is another side effect of the MSFS 2024 eye adaptation dimming the emissive textures during the day. In order to prevent interior and exterior lighting from being blown out during nighttime, we have tuned the lighting so that it provides an accurate level of illumination during nighttime operations.
6. There are several bugs with the MSFS 2024 Main Menu that can cause confusion and inconsistencies with products that have been developed in MSFS 2020. Such bugs that can be expected are thumbnails not loading, liveries appearing in non-alphabetical order, and statistics not displaying accurate data.
7. In some instances, MSFS 2024 can begin to cull sounds, possibly as performance-saving measures. This can cause instances where all sounds are playing correctly at the start of a flight, but the same sounds may be missing at the end of a flight.
8. Clicks on the interactive paper charts/checklist may trigger controls that are located directly behind them. This is a necessary side effect of a change we have had to make to the Paper Charts/Checklists interaction type, in order to allow more consistent responses to mouse clicks.
9. A widespread VRAM ‘leak’ in MSFS 2024 can severely affect a user’s FPS (this is a specific bug with the core simulator that is causing excessive VRAM consumption, resulting in situations with FPS in the single digits). This can affect any aircraft in the simulator and although PC builds with a higher RAM/VRAM can help mitigate this, the issue can also affect users even with the top-of-the-line equipment.
10. The aircraft registration shown on the cockpit registration placard and paper interactive checklist will not show the correct registration for the chosen livery. This is a limitation of MSFS 2024 where a random registration is assigned to the aircraft at the start of every flight and the user cannot remove that registration entirely. The simulator is also forcing a different cockpit registration placard font and texture compared to the MSFS 2020 version.
11. There are various timer-related issues within MSFS 2024 that are causing inconsistencies across the product. For example, the time indicated by the aircraft’s clock and the navigation equipment is currently reflecting your local PC time instead of the time within the simulator. Variations in the simulator’s timers can also affect such things as APU/GPU start-up timings and other systems logic. Some fixes/improvements to the in-game timers are expected to be fixed in the upcoming MSFS patch 3.
12. Pilot characters may be missing in the cockpit of products developed in MSFS 2020.
13. Various issues with the LOD system in MSFS 2024 can prevent the correct LODs from displaying at the necessary times. This may be most noticeable when moving the drone camera into the fuselage and the high-quality interior LODs won’t be loading like they would in MSFS 2020.
