Tacview 1.5 is now available to everyone!

While - at the first sight - this version does not look very different from the 1.4.3, it is a huge leap forward! This is simply the biggest upgrade to date: It took about 8 months of hard work and debugging to perfect a whole new telemetry engine and file format.

Why all this work?

The new telemetry engine is more powerful, transparent and efficient than ever:

* It can manage any kind of data even unknown one. The owners of the Home and Professional editions can now use the new raw telemetry tool to have a look at all the data recorded for each object of the battlefield. In a future release, new customizable telemetry windows will be introduced, in addition of the raw telemetry tool, to replace the old - and now overloaded - telemetry ones.

* This new engine also supports real-time data recording… which will soon lead to real-time flight data recording for the devices and simulators which support this kind of feature (like DCS World, FSX, X-Plane…)
* Thanks to lossless optimizations and improved structures, the new engine requires two times less memory to load the same amount of data as before!
* Thanks to full 64-bit floating point precision and spherical interpolations, replays are much more accurate than before, especially when analyzing real-life data and intercontinental flights.
* The “good” old text and compressed binary file formats are gone! From now on, Tacview will save all of your data in a much cleaner and more intuitive text format (optionally compressed in zip, and soon 7z). Please note that DCS World and FSX exporters will switch to this new format soon.
* This new file format is very easy to learn and to master. This means that, with just a bit of programming knowledge, you can easily create your own exporter. You can even create a file by hand - like show bellow - to inject data in Tacview world. A detailed documentation for the acmi 2.0 file format is available online: http://www.tacview.net/documentation/acmi/What does that mean for you?

These two major improvements will soon enable really useful features. Here are two obvious examples:

* Real-time flight data recording, replay and analysis: Soon you will be able to see a flight in progress! Which is going to be very useful for instructors and referees.
* Soon, all the data available in your cockpit will be visible in Tacview: Like fuel flow, controls position and even the pilot point-of-view and head movements!What about Bullseye?

Tacview 1.5 natively support the display of bullseye and bullseye coordinates. For now, you can display a bullseye by creating and merging a tiny telemetry file like the following. Tools will be added soon so you can create and edit this kind of data directly from Tacview.

* Each bullseye is positioned using the “T=” statement in the following order: longitude in degrees, latitude in degrees, altitude in meters (altitude is used only for display purposes).
* Use the notepad to create a text file containing the following data and use the merge function of Tacview to add it to your flight data.
--- Code: ---FileType=text/acmi/tacview
FileVersion=2.0
100000001,T=41.72611|42.12278|2000,Type=Navaid+Bullseye,Coalition=Enemies,Color=Blue
100000002,T=40|44|2000,Type=Navaid+Bullseye,Coalition=Allies,Color=Red
--- End code ---

* Calibrated air speed for standard atmosphere can now be displayed in the telemetry window and labels
* Added an option to switch distances to feet under 2 nm
* Unknown objects are now displayed using related 3D meshes instead of just boxes
* Improved SAM/AAA threat zones display
* Hovering the mouse on anti-aircraft unit will display its thread sphere regardless of the global option
* You can now double click in the 3D view to toggle full screen mode
* Restored support for Windows XP (at least until the 3D render is rewritten)
* Updated Falcon 4.0 terrains and databases to BMS 4.33 U1
* Upgraded the export script to gracefully support DCS World 1.5.4 new export options
* Added preliminary support for DCS World F-5E-3
* Increased charts time and distance measurement marks resolution to 1/10 unit

* Improved GPX files support (invalid samples are ignored and more tags are supported)
* Improved KML files support for static objects (preliminary support of polygons)
* Selected objects labels are now always displayed regardless of the global option
* Removed multimedia keys support (mouse and normal keyboard controls are more than enough)
FIXES

* Fixed a crash when loading truncated lines in csv files
* Fixed a rare random crash when loading custom terrain textures

* FSX2ACMI now better handles pauses during a flight
* Fixed Falcon 4.0 RKND & RKNW runways position and orientation

Vyrtuoz:
Feel free to post here any questions and comments related to Tacview 1.5.

Please, create new threads for general questions.

Asid:
Great news.

Tacview is an excellent tool. I recommend it to all. Especially when there is a free version.

Keep up the good work Vyrtuoz.

Vyrtuoz:
Note for BMS users

Thanks to your feedback I have noticed that the day/night cycle is not correct with BMS VHS files.

This is because the time provided in VHS files is in local time instead of UTC.

I will manage properly this case in Tacview 1.5.1
