There is a few posts early on this thread about the training bond, but from the top of my head it's a 5 year bond if you actually pass the course and get rated. The number $70,000 comes to mind but don't quote me. Rumors are airservices only makes you pay if you leave for another ATC gig, not if you give-up ATC all together. There is no repayments, just have to do the 5 years.
