Practice Mode

I don't know 100%, but from the Official Gameplay Trailer, there is a moment from what I assume is a practice mode, it's at 1:27 in the video, where a the pilot is in a Tie Fighter going through what looks like an obstacle course, with what looks like a drone Tie named "HELIX  01" with slightly altered wings (a bit curved) as its target. It comes after the scene of the 5 pilots walking together.

I almost guarantee that's practice mode.  A throwback to the original games, where you flew obstacle courses and had to shoot drone targets.  It's not so helpful regarding how to fly in a dogfight, but really helps learn the basics of the controls.
