I am just coming to the end of my aerospace engineering degree and am taking the avionics option which is a part of the course.
I agree with Ghengis that you would be best looking up an Aerospace Systems course rather than a pure Avionics course because if you specilise too much you may not be Multidiciplinary enough for some applications.
Most Aero courses do contain modules where you can explore avionics and systems and there is plenty of scope to look at these areas.
Good luck fo the future
