Thanks a lot for replying.
Nice to here I dont need a university degree in history of aviation or something like that, because in spain(place where I currently live) few years ago there was a restriction when applying of needing to have a university degree in whatever. Yeah I knew they are not aerodrome pos. but eather I didnt know they served approach. One question that I have is: the people that pass the entry exams are they super mega clever you know like they can multiply super large numbers in one second and so one... Or are they just simply aviation enthustiasts with a suficient intigence that allows to multiply with time, a pen and a paper.( I am one of those 2d option)
