Hi. You have 2 modes:
HDG V/S
You set a heading and a vertical speed. In this case heading+wind=course.
TRK-FPA
You set a course and an angle. The “bird” is displayed in the PFD. Whatever the winds, your course is your course, whatever the speed, your angle is your angle.
Something like this:

What is the TRK and FPA system for? Is it for a VOR landing? VOR landings how does it work gets you to the runway? can the airplane land automatically following a glide slope? please someone help meTRK steers the plane left and right to maintain a selected track across the ground
FPA steers the plane up and down to maintain a constant descent or climb angle
The TRK and FPA modes don't react to a VOR needle or any glide path at all, you have to manually adjust the target TRK and FPA values to stay on your VOR radial. You cannot auto-land using the VOR and the autopilot does not capture the VOR itself.
To perform an auto-land you need to use an ILS and use the proper approach modes LOC and G/S.
Please read our tutorial on Airbus autopilots which describes VOR and ILS approaches.
