For me, I hate studying thing that don't (or barely) move, and I prefer my objects of study to be moving at several hundred km/h at least, so for me aeronautical was a natural choice of mechanical.
I love aircraft everytime i travel and im at the airport im always looking at the aircraft, things the models of aircraft types of different engines etc...this is what started my love for aerospace/aeronautical! Aerospace and aeronautical are virtually identical just maybe 1 or 2 modules in the last year are different. The only reason for mechanical is from what i read on the course structure most universities have modules in aerospace,civil,electronic etc that you can choose from in your final year of study...so with that in mind i wanted to do mechanical then in last year specialise in aero. However i need to start going to open days and asking the lectures these questions perhaps that will help me even more to decide. One question about open days do you pay to go to the uni or is it just transport you have to pay for?
