# Flight Log

With Tacview, you can easily convert any flight recording into a clean flight log to create and update online rosters for your virtual squadron. The data generated is the same as the one visible in the events list. It can be exported in either `XML` or `CSV` file format depending on you technical needs.

It is possible to export data from the command line to easily automatize data gathering after each flight session. Use your own program or PHPTacview to compile these data and to display always up-to-date statistics for your pilots on your squadron website!

Go to **Analysis → Flight Log** to open the flight log.

Here Tacview logs different events that it was able to auto-detect such as `Has fired`, `Has been hit`, `Has been destroyed`, and others:

Double-click on an event to be taken to that moment in the replay:

Any bookmarks that you add will show up in the flight log:

Export the flight log to CSV or XML and to make your own tools such as scoreboards:

![Flight Log - Export](https://681332907-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZ9tiJ3xbT7zyJ4FlZiMM%2Fuploads%2Fgit-blob-cb68470a1ef383ee167be16943f4358f6a882ed9%2Fflight-log-export.png?alt=media)

Or use the command line option:

`Tacview.exe -Open:"Tacview-20150512-191044.acmi" -ExportFlightLog:"Mission Black Gold.csv" -Quiet –Quit`

CSV flight logs are saved in the `UTF-8` format and are using the comma , to separate data fields. You can easily load `CSV` files generated by Tacview in a program like Microsoft Excel. Its content can be understood just by looking at each column headers.

Here is an example of a CSV Flight Log:

And here is an example of an XML Flight Log:

Before starting to work from scratch on a whole new program, I suggest you to have a look first at [Ezor's PHPTacview](https://www.tacview.net/download/addons/en/#phptacview) written in PHP. It can either fulfill your objectives or act as a starting point for your own project. In any case this is a very interesting use of Tacview `XML` flight logs. PHPTacview is an open source project.

In the next and final section of this chapter, we will learn about engagement ranges and mention some other tips about engagements.
