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.
Instructions
Extract and run FlightRecorder.Client.exe.
Features
- 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.
Incompatibiity
- 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.

Great little addon, thank you very much for putting the time in to make it, I'm sure it will get a lot of use.
A feature that would be great is the ability to record other aircraft as well (Multiplayer and AI). Hopefully this is something you might be able to add in the future

Hi ! do you know why Spoilers are not active during landing replay ? Thank you and by the way congrats for this awesome and friendly use tool ! A must to have !

I really hope this great program will be supported and developed further. It's much better and easier to use than what Asobo is currently trying. Their approach looks more like an advanced screen recorder. So, sitting in your own plane as passenger or just simply replay and watch your landings from outside is not possible.
This Flight Recorder on the other hand, is doing exactly what most users will expect (and also content creators). The only things I am still missing are the engine startup and the support of prop lever / rpm.
Please continue your great work!

Really good free alternative to other replay software and in my opinion better than the one Microsoft implemented with SU7. Only thing holding it back is the engine autostart!

5 stars for this mod - it's simply phenomenal. Could you help me solve one problem though? The spoilers on the A320 keep extended during the replay for some reason...any solution?
nguyenquyhy 11 day(s) ago
Interesting. I did not notice that before. Can you please try to check in the cockpit if the spoiler handle moves correctly? The tool records & replays the handle position so that should work.

Hello, Can this tool be used to practice approaches or pick up where a CTD occurred? I just had a bizarre experience where my plane would only veer left but not right. I wish I could pick up flight from there and try to see if it was just a bug.

Hello. Is there a way to update so that FS Recorder doesn't disengage the AP after replay is finished? My plane went all over the place soon as the replay was done and then it fixed itself once I hit AP. If there's a way to update that would be great.
nguyenquyhy 15 day(s) ago
The tool does disengage the AP unfortunately (it doesn't even record AP states). I think the problem is that AP freaks out because the aircraft stops responding to its command and disengages itself.

Is there any way that car traffic can be slowed down along with a .75% or .50% recording speed of the flight? That way, a slower flight can be sped up in a video editor and the cars wouldn't be going way super fast. Also, with a .50% recording speed, one can load up the visual parameters to maximum including packed freeways at sunset. Thanks for this great program!
nguyenquyhy 13 day(s) ago
Right now the tool works via SimConnect (which is an interface to get & set sim data). I believe car speed and visual fidelity are not variables that can be accessed via SimConnect at the moment 😞.

When I try to replay my game is crashes.. How to fix it ?
LundMaroChus
Excellent work, so far best tool for MSFS 2000, Well done for this tool where Asobo is struggling to bring this for months
iliasr
it's precious mod, please make a REPEAT option ,
thanks a lot
JackBack
Thank you very much!
CaptainKian
Its amazing. You can record it when ever you want and see all your landings
asaluto
I have I problem....Windows stop the file ...... .exe to install the program so I can not install the software. What can I do? Thank you.

you could try to put it in a zip-folder, then extract it. And open.

This mod continues to represent one of my most beloved. Thanks again for all your efforts. One thing for me, I keep getting a complete sim freeze requiring me to 'end task' when attempting to play back a replay of landing at LFMN Nice. This is the only airport that does this and have repeated the problem several times. Could it be that flight recorder is simply overloaded by all the detail at this airport? I do have my graphics settings at ultra. This has never happened at any other airport no matter how complex. Something in Nice that the mod doesn't like.

Hi, do you know why when starting a replay from a gate, all other AI aircraft disappear ....
flightzoomer
Hi, thanks for this great little tool as well as for making it open source!
Since SU6 I experience that replay does not work anymore. When starting replay, the aircraft moves to the initial position of the recording, jumps forward and back for a moment and then stays glued to the initial position forever. Any idea for the reason for that? The same happens with the latest download 0.18.2, as well as the self compiled 0.15.0.0.Sorry, all my fault, should wind forward the replay, the flight was paused the first few seconds of the recording!

Awesome 😀
Dravman
I'm using Windows and your app is running Ok but there is something strange with the interface ( display bugs, strange behavior I never got before SU6) since Sim Update 6. I just got a CTD reaching the 3/4 of the flight replay . Perhaps you need to provide an update of your nice app ? , I will retry and check again from my side. Thank you
nguyenquyhy 1 month(s) ago
Can you please file a GitHub Issue with the link in description and attach your recording so I can try it out?
However, in general I can only fix crashes of the tool itself, and it is very little I can do about CTD. The tools simply sends back data it gets from the sim without touching the physic or graphic engine.
Dravman 1 month(s) ago
ok thank you and I will do ! will restest today using the same replay

I really like this mod, thank you so much. Tell me, if I record a whole 6 hours flight but don't save it, where the datas are stocked ? In the memory ?
André
nguyenquyhy 1 month(s) ago
Yes if you don't save, the data will be in the memory until you close the tool or start a new record.
aviateur 1 month(s) ago
That what I was expecting. Thanks.

Works great with SU6.
