How to use Tacview with Microsoft Flight Simulator X or Lockheed Martin® Prepar3D®?

FSX2ACMI
Q: Which versions of Flight Simulator are supported by Tacview?

A: Tacview has been tested and validated with the following editions of Flight Simulator:

Q: How should I use FSX2ACMI to record Flight Simulator flights?

A: First, make sure you have downloaded and installed the latest version of Tacview. This will install FSX2ACMI on your computer. Launch FSX2ACMI from Windows start menu or search box. As long as FSX2ACMI is running, it will record all your Flight Simulator flights automatically.

Q: Why do I get an error when I launch FSX2ACMI with Prepar3D v3?

A: Like many universal add-ons, FSX2ACMI needs Microsoft Flight Simulator SimConnect to be properly installed to access telemetry data. If you are using Prepar3D® v3, you have to manually install SimConnect by running:C:\Program Files (x86)\Lockheed Martin\Prepar3D v3\redist\Interface\FSX-SP2-XPACK\retail\lib\SimConnect.msi

Q: How do I stop the recording of my flight?

A: You can either close FSX2ACMI or Flight Simulator. FSX2ACMI will also automatically start a new recording when it detects a major change in the current flight (like time or mission change).

Q: Where are my flights recorded?

A: You will find all your flight recordings in \My Documents\Tacview\. You can click on the corresponding hyperlink in FSX2ACMI to open this folder. You can also change this folder for another one by using the appropriate option in Tacview.

General Questions

Q: Does Tacview work with network flights?

A: Yes. FSX2ACMI does not make any difference between local and remote objects. This is why your flight should be properly recorded and should include all the other pilots connected to the same session as you and flying in the same region.

Q: Does FSX2ACMI supports add-ons like Tacpack?

A: Yes, you can use FSX2ACMI with any add-on. If you are using it with Tacpack, you will get two flight recordings, one from Tacpack and one from FSX2ACMI. In that case, the one from FSX2ACMI may give better results since FSX2ACMI is always supporting the latest features of Tacview like the advanced telemetry.

Q: When I replay my flights in Tacview, the terrain is either empty or low-res. How can I improve that?

A: The Free edition of Tacview does not offer terrain coverage for the whole earth this is why you will probably see water most of the time. The Home edition offers am ETOPO1 base map for the entire world. This is much better than just water; however it may look kind of blurry. Here are some ways you can improve the default terrain:

  • First, you should try on of the official terrain add-ons.
  • You can also import official SRTM maps from NASA. These are the exact same maps Flight Simulator is using by default.
  • Or you can ask me to add the terrain of your choice in the download section. Please be patient in that case. Even if I will do my best to deliver you the map quickly, I'm quite busy on other tasks...
Q: Can FSX2ACMI slow down my computer?

A: No, it should not. On today's computers FSX2ACMI uses about 1% of CPU while recording. This has been tested on a 2012' PC running FSX at maximum quality and 100% AI air and ground traffic (about 400 to 800 moving objects).
