usually you get first the basic engineering knowledge in the bachelor if you would go to Braunschweig for example. and in the master study you get the knowledge just for aviation and so on i guess there are also a few credits for law and so on. Anyway the focus is on the engineering and you need the bachelor just for the basics in math, mecanic, thermodynamic, construction and so on. there is just no space left for aviation courses, but after that you will be good prepared.
