G Loads
« on: February 28, 2020, 01:13:57 PM »
I am using Tacview for some ADS-B data analysis.  Right now, Tacview shows the metric "G", which is the normal G load.  Is there any way I can get the axial and side G loads as well?

Hi,

In your ADS-B data do you have roll, pitch and yaw?

If so we could try adding axial & side G loads.

I have generated the roll, pitch, and yaw from the ADS-B data.  By seeing the axial and side loads I would have greater confidence in my process.  Here is a link to a video of what I am modeling.   
I already have the data in Tacview and I think it is really cool. Thanks for your consideration!  P.S.  Can you tell me how to change the reference time for the data I open as a CSV?  My timecode starts at 0.0 and I want to see the actual date/times in Tacview.

Great! The UI is pretty full but we could add axial and side loads in the export and/or labels. Would that work for you?

To amend the time, go to Debriefing -> Time Shift to shift the time to UTC time you want then go to Options -> Time Offset to choose the correct UTC offset.

Seeing it in the exported telemetry would be fantastic!  Thanks for the tip on the time shift.

Here is a quick, not publicly published, video showing the flight path visualized in Tacview.  I am using it test a hypothesis I have about the crash.



It doesn't matter much, but is there a way to do a chase plane?  The external view doesn't chase, it appears to keep the same bearing.

Thanks!

OK we'll add axial and side loads to exported telemetry in a coming update.

Nice work on that video. If you want to get rid of the active objects overlay you can disable the add-on through Add-Ons -> Enable/Disable Add-Ons -> Lua Tutorial 6 - Active Objects

To get a view kind of like a chase plane, try using the button between the two selected object drop down menus on top. Make sure the button is activated (it will in color if it is activated) and pick either Look Forward or Look at Target and pan the camera around (in the case of Look at Target) to get a view you like.

That's awesome!  Thank you!  I also sent in bug report today on some display issues I am seeing.  Sorry to be a pain.

I am looking to add G-force displays via LUA.  I see where I can get the Vertical G and Absolute G, but is there an interface where I also get the LatG and LongG values from LUA?  Thanks!

We'll try to add this in a coming update. I'll let you know!
