I don't know why companies like Aerologic doesn't write clearly in theirs pilot requirements that the applicants should speak/write/read GERMAN..
Proficient in English, German desirable but
not mandatory
I would say, this is what you want.
BTW: All emails I have received are in english.
@what_goes_up na dann is ja alles klar
As you might know the german tax system is not known as the easiest one,
it depends on a few factors, married and does your wife work or not, kids.
I would say with 3 kids your net should be around 60k per year, could be more, but 5k net per month plus per diem should be the minimum.
