I have recently written a simple tool to record and replay my flight and would like to share it with the community.

And thanks IamSean for allowing me to include his video as a showcase of the tool's capability and the awesome graphic fidelity of MSFS.


Extract and run FlightRecorder.Client.exe.

  • Record and replay with your aircraft or an AI aircraft in the sim
  • Change replaying speed
    • NOTE: when speeding up, your computer might not be able to load scenery fast enough and that will negatively affect frame rate.
  • Save recording into a file to replay later or on another computer
  • Export the recorded data into CSV for further analysis
  • Quickly jump to any time in your recording (you have to Pause Replay first)

Notes: The tool records this list of variables from SimConnect Structs.cs for each sim frame. Some of them are only for analysis and display and don’t affect replay.

  • FBW A32NX
    • The 32NX starts to replace existing code that works with SimConnect with new code that ignores SimConnect. This means the aircraft will ignore the replay data Flight Recorder send to the sim. You will see that certain variables get replayed as in other aircraft, and the rest don't.
    • Workaround (suggested by Abriael): since the recording still has correct data, you can replay it on stable/dev variant of the 32NX, or even the default A320.
  • Default A320 and A23NX
    • Aileron reacts wrongly to simvar `AILERON POSITION` when aircraft is in the air.
    • I have reported this in ZenDesk #95574. I'll wait for Sim Update 4 before working on a workaround.
Other Limitations and Notes
  • When starting a replay, your aircraft might be teleported to a far away location which doesn't have loaded terrain. This means the ground can jump up/down really quickly and you might get a crash (not CTD) due to damaged landing gear. Disable crash detection might be a good idea if you frequently replay your flight.
  • I don’t know a reliable way to tell if an engine is running or not, so this tool does not auto-start the engine (because it doesn’t know when). Hence, you should start recording/replaying when engine is already running (or the aircraft will move without a running engine) and stop recording before turning off the engine (not really a problem, but the tool might not shut the engine down for you). Not doing that won't prevent you from replaying or using any features, but replay can look like your aircraft is powered by magic ;).
  • Replay looks weird when turning on the ground. I’m not so sure what is happening there yet.
  • To prevent fighting with MSFS own calculation, the tool sends freeze command when you start replay and unfreeze when you stop replay.
    This means replaying might conflict with other tools leverating the same freeze feature (e.g. YourControl when you are not in control, other replay tools).
  • AI aircraft jitters back and forth during replay, especially at high speed. I'm still trying to figure out the reason.
Reporting Issue

If you have any issue with the tool, please report it in our GitHub page with information for troubleshooting such as screenshots, logs and profile exports.

is it planned one day to have a recording in MP4 ? but already thank you for what you did 😉

Can a recorded flight be partially exported ? It means It would be great to have an option to select just a part of the recorded flight to be exported

Ever since the current update, the recorder records flights just fine - Replay causes the sim to CTD. Every time. Regardless of recording location - As soon as I start replay within 2 minutes or less I get a CTD.

Hi, could you please update your software to include PMDG 737 and inibuilds A310? I did some recent recordings on those recently and the replay doesn't work well, for example some replayed events are not in sync with recorded events, ie flaps etc..

This software is powerful, thank you.

Hi! I cannot open the .exe-file. I have extracted the content to my C:\-drive but when I try to open the .exe-file FlightRecorder.client it says "you'll need a new app to open this .exe file" and I get directed to Microsoft store. I have googled this and checked the settings for .exe-files in the registry and also reset the Microsoft Store app. I have only problems with FlightRecorder. Any other apps seem to be running without any problems. Anyone else with the same problem?

Hello all,

after i found this Flight Recorder i was really happy to have now a Tool for easy replaying in MSFS.

That works like a Charme since the beginning.

Then you must know i have a Homecockpit and dont want to use a Keyboard or Mouse.

For that i have a own program which controls most of the Functions i need.

The Problem with the Flight Recorder was that i have to save the recording before i can start a new recording.

For that i ask the developer on Discord to add this functionallity.

After a short conversation on Discord he adds this functionallity just for me !!

Even i think it is a nice function for all of us, i would give the Developer a BIG THANKS for adding this just because of my Request.

Thanks a lot so much


I got a warning from my anti-virus a couple of days ago say that this app was not trusted and was accessing the internet so with my antivirus I blocked the app from accessing the internet. One week later this tool still works fine with it being blocked from the internet so why does this tool connect to the internet?

This app is great. I love the way you can replay and switch views from one to another.

First of all the tool is great but I have one problem: flying with flightrecorder recording the flight in the background is no problem, i get stable fps. Then after the flight I start the replay. Takeoff and cruise is very nice but when I skip forward to the approach and wait for the scenery to load and then resume the replay after one minute of pause I only have about 10-15 fps and it stays that way all the way to the gate, then I exit the flight recorder and want to go on with my next flight but MSFS is still at 10 fps. I need to go back to the main menu and reload to get my regular fps back. This only happens when using flight recorder. The recorder itself works very well but the fps go down way to much for some reason in certain flight phases.

I like the video recorder today I have noticed for some reason my friends aircraft does not show in the replay, I have seen other aircraft in my replays before is it supposed to show everything, i could see him during the recording but as soon as I replayed it he was invisible.

Thank you for sharing!

On approach I get lag spikes up to 10 fps and its literally unlandable

idk if its the mod but potentially

update 10?



3 month(s) ago / Kiitti nguyenquyhy

thank you, this is an amazing add-on! everyone must have it!!

I just want to know if it is possible to record the traffic AI generate by me. It would be very interresting to make some formation

hey i just downloaded it so i just put it into the community folder and it works. Or do i have to do some other stuff

will it allow to change camera views during the replay?

the replay mod in the sim doesn't allow that.

Nice addon. What happen to the "stay on top" button?

So, I have used this with the fenix and unfortunately the control surfaces are inverted. I have seen that this is an issue with most of the planes, so if there is any way you can fix this, then I will give 5 stars instead of 4!!

not hating just asking for help when i went to replay my flight/landing i started free falling through the sky

Usein kysytyt kysymykset

Kysymyksiä? Löydä ratkaisu täältä.

How to install/upgrade the tool?
You can just download the zip file of any version, unzip it and run FlightRecorder.Client.exe.
What are the differences between Save and Export?
Save produces a .flightrecorder file that can be loaded later by the tool (using Load button).
Export produces a .csv file that can be opened in Excel for analysis.
Why does reverser not work?

There seems to be a bug in the 32NX experimental version that does not react to thrust lever data from SimConnect, which means the tool has no way to activate reverser. I have filed an issue at (from the look of it, doesn't seem like FlyByWire will fix the issue).

If you are not using that version, most likely you are using a physical thrust lever that conflicts with Flight Recorder by trying to take over control from the replay tool. The easiest way to test this (also a workaround) is to create a clone binding profile and remove the thrust binding.
