I recommend you to check on pilotjobnetwork to find salary information, it's pretty much the numbers which were given to us.
Otherwise, read the previous pages of this forum, as far as I remember, some other Infos were given.
About the monthly repayment, it should be more around 450-500 Eur per month during 3 years.
For the loan, it all depends on your country I would say. For example, as French we have very interesting student loans (around 1% 1,5% fixed rates), so you pay around 700 Eur per month during 8 years for getting 60k Eur.
Just an example but it can be different in your country, I even guess it is.
