Lear45 in FS2020 Troubleshooting


On August 18th 2020 the highly anticipated FS2020 was released!  As of this date, it has been a bit of a bumpy ride but if you are able to see past it's short term imperfections, it is clear this is the Flight Simulator of the future.  Find more information about Microsoft Flight Simulator 2020 HERE

If you are a member of the Hangar45 community, it is safe to say that you have noticed there is not a default Lear45 among the short list of aircraft to choose from.  (Additionally, there has never been a third party Lear45 developed for either FSX or P3D.)  But that okay, we would expect the developers of the new FS2020 to concentrate initially on a small number of aircraft to get things kicked off.  With that said, even if they had a default Lear45 XR as an option, it would most likely have short falls just like the other default aircraft.

Thankfully MSFS has created an import tool that enables us to import our favorite FSX/P3D aircrafts into the new FS2020 which is still a work in progress with no less than 13 updates and the last being on December 9th 2020.  Take a look at the update log for a long list of fixes and features added:

If you have had a high degree of success importing your FSX/P3D Lear45 model over into FS2020, please share your findings and results in this thread.  To date, it appears that importing the FSX/P3D Lear45 into FS2020 is very achievable!  Take a look at these two screen shoots!


However, there are several issues that we have identified and have not found viable solutions for yet.  This thread is going to serve two purposes, first, to identify import issues and second, to document solutions to those issues.

Here is our short list so far:

  • Able to import aircraft visual model which does include the VC. Instruments do not load
  • Autopilot does not appear to be working (may be because of instrument issue above)
  • Lights are not placed correctly on the aircraft and need to be relocated to the model
  • Engine does not go below 50% N1 at Idle
  • Spoilers don’t extend fully
  • Aircraft requires nearly full trim nose down to fly level


If you have found and identified any issues and or discovered solutions for any issues previously posted, please document your findings here.  Also, please keep your identified issues and solutions specific to the Lear45 aircraft so that we can better streamline this thread!  Hopefully with everyone working on these issues we will have a viable Lear45 FS2020 model in no time flat!

Merry Christmas by the way!

Merry Christmas, Ron

I remember reading somewhere, can't remember where, that vc models are contained in a model folder, not in the individual aircraft object file. Also, if the autopilot gauge is not .xml, it may not convert.

I discovered the camera option in the latest FS2020 build called "Home Cockpit Mode"
It does not do anything...yet..
But this is promissing about Asobo developing an outside view option!!

So far, all of my research suggest that if we are ever going to see a Lear45 in the new FS2020 it is most likely going to be up to one of us or a combination of several of us to make this happen.

The "porting over" option looks to be a temporary bridge to pacify guys that have a favorite aircraft to fly (guys like us), but there are several issues. First, every time MSFS updates, the ported over aircrafts get lost or deleted. The other issue is the porting over process is not perfect. It has engine issues, 2D cockpit views are messed up just to name a few.

Our long term solution to flying a Lear45 in the new FS2020 sim is to start from scratch and develop it within the SDK. Have you had a chance to play around with the SDK side of the new sim yet? I have not, but understand that there are many examples and tutorials.

I've been flying the CJ4 business jet in MSFS 2020, and have interfaced some of the panel controls from Lear45 into MSFS 2020.  For an example, the "Landing Gear" works in the sim, as well as some of the other switches.  Has anyone else noticed this?

I have not had a chance to use FS2020 with a desktop computer yet, only some lite Xbox use so far.  I have been super busy making parts and interface modules for the upcoming Lear45 v2.0 and Jet45 v2.0

We believe most of the basic controls will be very easy to interface in the CJ4 like you have already discovered.  Between what is already possible right off the bat and what the Jet45 AAS/Systems software that Jason is working on will do for us, this will get us about 95% of the way there.

A few things that I can think of that the CJ4 does not have (correct me if I am wrong) is an APU and thrust reversers.  Those are two big things that will be missed if we can't get them working in a CJ4 model.  I am not sure how difficult it would be to "steal' these items from another airframe and transplant them into a hybrid version of the CJ4 and then renamed a Lear45 model.

Unfortunately all the work I have done within this part of the sim is in theory only......lately.  I think one of my 2022 goals is to dive straight into the FS2020 SDK to see for myself what is possible.  No doubt we need a fully functional Lear45 model.  It is 100% possible, we just have to find the easiest solution forward that we will all be happy with.

Yes, actually the CJ4 is very similar to the Lear45, even the glare shield.  But to answer your question, you're right there's no APU from what I can gather.
