With Tacview Starter you can display basic telemetry. If you need more detailed aircraft status reports, Advanced Telemetry is available in Tacview Standard.
Go to Options → Raw Telemetry 1 to see the advanced telemetry of the primary selected object:
Advanced Telemetry - Raw Telemetry
Any numeric or text property included in the ACMI file will be displayed here, even those which are not explicitly supported by Tacview.
Many of these Advanced Telemetry values will also be available in other tools such as charts, labels, the cockpit view, and more.
Using the public file format and the SDK, advanced users can create their own files containing custom properties and perform detailed analyses.
