What is this part of the “Flight Data” used for? What does it represent?

Calculated environmental wind speed and direction.

That is an artificial horizon with airspeed, compass and altimeter data around it. It can be called a “heads-up-display” HUD if there is enough info to fly the drone/plane without looking at any other items on the screen.

Sorry about my last post…I did not see your call out.thought you were referring to the artificial horizon
