Help with Interview for air traffic control engineer position
 

I am going for an interview tomorrow for an air traffic control position and was hoping someone could give me some guidance about what I may need to know. I also have to sit a test in the interview (which apparantly I will need the log function on my calculator for) and was wondering if anyone may have any ideas what sort of problems I will be asked to solve? Hopefully someone will be able to help! :confused:
